It performs the same checks as +\fBnamed\fR +does when loading a zone. This makes +\fBnamed\-checkzone\fR +useful for checking zone files before configuring them into a name server. +.PP +\fBnamed\-compilezone\fR +is similar to +\fBnamed\-checkzone\fR, but it always dumps the zone contents to a specified file in a specified format. Additionally, it applies stricter check levels by default, since the dump output will be used as an actual zone file loaded by +\fBnamed\fR. When manually specified otherwise, the check levels must at least be as strict as those specified in the +\fBnamed\fR +configuration file. +.SH "OPTIONS" +.PP +\-d +.RS 4 +Enable debugging. +.RE +.PP +\-h +.RS 4 +Print the usage summary and exit. +.RE +.PP +\-q +.RS 4 +Quiet mode \- exit code only. +.RE +.PP +\-v +.RS 4 +Print the version of the +\fBnamed\-checkzone\fR +program and exit. +.RE +.PP +\-j +.RS 4 +When loading the zone file read the journal if it exists. +.RE +.PP +\-c \fIclass\fR +.RS 4 +Specify the class of the zone. If not specified "IN" is assumed. +.RE +.PP +\-i \fImode\fR +.RS 4 +Perform post\-load zone integrity checks. Possible modes are +\fB"full"\fR +(default), +\fB"full\-sibling"\fR, +\fB"local"\fR, +\fB"local\-sibling"\fR +and +\fB"none"\fR. +.sp +Mode +\fB"full"\fR +checks that MX records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). Mode +\fB"local"\fR +only checks MX records which refer to in\-zone hostnames. +.sp +Mode +\fB"full"\fR +checks that SRV records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). Mode +\fB"local"\fR +only checks SRV records which refer to in\-zone hostnames. +.sp +Mode +\fB"full"\fR +checks that delegation NS records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). It also checks that glue address records in the zone match those advertised by the child. Mode +\fB"local"\fR +only checks NS records which refer to in\-zone hostnames or that some required glue exists, that is when the nameserver is in a child zone. +.sp +Mode +\fB"full\-sibling"\fR +and +\fB"local\-sibling"\fR +disable sibling glue checks but are otherwise the same as +\fB"full"\fR +and +\fB"local"\fR +respectively. +.sp +Mode +\fB"none"\fR +disables the checks. +.RE +.PP +\-f \fIformat\fR +.RS 4 +Specify the format of the zone file. Possible formats are +\fB"text"\fR +(default) and +\fB"raw"\fR. +.RE +.PP +\-F \fIformat\fR +.RS 4 +Specify the format of the output file specified. Possible formats are +\fB"text"\fR +(default) and +\fB"raw"\fR. For +\fBnamed\-checkzone\fR, this does not cause any effects unless it dumps the zone contents. +.RE +.PP +\-k \fImode\fR +.RS 4 +Perform +\fB"check\-names"\fR +checks with the specified failure mode. Possible modes are +\fB"fail"\fR +(default for +\fBnamed\-compilezone\fR), +\fB"warn"\fR +(default for +\fBnamed\-checkzone\fR) and +\fB"ignore"\fR. +.RE +.PP +\-m \fImode\fR +.RS 4 +Specify whether MX records should be checked to see if they are addresses. Possible modes are +\fB"fail"\fR, +\fB"warn"\fR +(default) and +\fB"ignore"\fR. +.RE +.PP +\-M \fImode\fR +.RS 4 +Check if a MX record refers to a CNAME. Possible modes are +\fB"fail"\fR, +\fB"warn"\fR +(default) and +\fB"ignore"\fR. +.RE +.PP +\-n \fImode\fR +.RS 4 +Specify whether NS records should be checked to see if they are addresses. Possible modes are +\fB"fail"\fR +(default for +\fBnamed\-compilezone\fR), +\fB"warn"\fR +(default for +\fBnamed\-checkzone\fR) and +\fB"ignore"\fR. +.RE +.PP +\-o \fIfilename\fR +.RS 4 +Write zone output to +\fIfilename\fR. If +\fIfilename\fR +is +\fI\-\fR +then write to standard out. This is mandatory for +\fBnamed\-compilezone\fR. +.RE +.PP +\-s \fIstyle\fR +.RS 4 +Specify the style of the dumped zone file. Possible styles are +\fB"full"\fR +(default) and +\fB"relative"\fR. The full format is most suitable for processing automatically by a separate script. On the other hand, the relative format is more human\-readable and is thus suitable for editing by hand. For +\fBnamed\-checkzone\fR +this does not cause any effects unless it dumps the zone contents. It also does not have any meaning if the output format is not text. +.RE +.PP +\-S \fImode\fR +.RS 4 +Check if a SRV record refers to a CNAME. Possible modes are +\fB"fail"\fR, +\fB"warn"\fR +(default) and +\fB"ignore"\fR. +.RE +.PP +\-t \fIdirectory\fR +.RS 4 +Chroot to +\fIdirectory\fR +so that include directives in the configuration file are processed as if run by a similarly chrooted named. +.RE +.PP +\-w \fIdirectory\fR +.RS 4 +chdir to +\fIdirectory\fR +so that relative filenames in master file $INCLUDE directives work.

DESCRIPTION

+

named-checkzone + checks the syntax and integrity of a zone file. It performs the + same checks as named does when loading a + zone. This makes named-checkzone useful for + checking zone files before configuring them into a name server. +

+

+ named-compilezone is similar to + named-checkzone, but it always dumps the + zone contents to a specified file in a specified format. + Additionally, it applies stricter check levels by default, + since the dump output will be used as an actual zone file + loaded by named. + When manually specified otherwise, the check levels must at + least be as strict as those specified in the + named configuration file. +

+
+
+

OPTIONS

+
+
-d
+

+ Enable debugging. +

+
-h
+

+ Print the usage summary and exit. +

+
-q
+

+ Quiet mode - exit code only. +

+
-v
+

+ Print the version of the named-checkzone + program and exit. +

+
-j
+

+ When loading the zone file read the journal if it exists. +

+
-c class
+

+ Specify the class of the zone. If not specified "IN" is assumed. +

+
-i mode
+
+

+ Perform post-load zone integrity checks. Possible modes are + "full" (default), + "full-sibling", + "local", + "local-sibling" and + "none". +

+

+ Mode "full" checks that MX records + refer to A or AAAA record (both in-zone and out-of-zone + hostnames). Mode "local" only + checks MX records which refer to in-zone hostnames. +

+

+ Mode "full" checks that SRV records + refer to A or AAAA record (both in-zone and out-of-zone + hostnames). Mode "local" only + checks SRV records which refer to in-zone hostnames. +

+

+ Mode "full" checks that delegation NS + records refer to A or AAAA record (both in-zone and out-of-zone + hostnames). It also checks that glue address records + in the zone match those advertised by the child. + Mode "local" only checks NS records which + refer to in-zone hostnames or that some required glue exists, + that is when the nameserver is in a child zone. +

+

+ Mode "full-sibling" and + "local-sibling" disable sibling glue + checks but are otherwise the same as "full" + and "local" respectively. +

+

+ Mode "none" disables the checks. +

+
+
-f format
+

+ Specify the format of the zone file. + Possible formats are "text" (default) + and "raw". +

+
-F format
+

+ Specify the format of the output file specified. + Possible formats are "text" (default) + and "raw". + For named-checkzone, + this does not cause any effects unless it dumps the zone + contents. +

+
-k mode
+

+ Perform "check-names" checks with the + specified failure mode. + Possible modes are "fail" + (default for named-compilezone), + "warn" + (default for named-checkzone) and + "ignore". +

+
-m mode
+

+ Specify whether MX records should be checked to see if they + are addresses. Possible modes are "fail", + "warn" (default) and + "ignore". +

+
-M mode
+

+ Check if a MX record refers to a CNAME. + Possible modes are "fail", + "warn" (default) and + "ignore". +

+
-n mode
+

+ Specify whether NS records should be checked to see if they + are addresses. + Possible modes are "fail" + (default for named-compilezone), + "warn" + (default for named-checkzone) and + "ignore". +

+
-o filename
+

+ Write zone output to filename. + If filename is - then + write to standard out. + This is mandatory for named-compilezone. +

+
-s style
+

+ Specify the style of the dumped zone file. + Possible styles are "full" (default) + and "relative". + The full format is most suitable for processing + automatically by a separate script. + On the other hand, the relative format is more + human-readable and is thus suitable for editing by hand. + For named-checkzone + this does not cause any effects unless it dumps the zone + contents. + It also does not have any meaning if the output format + is not text. +

+
-S mode
+

+ Check if a SRV record refers to a CNAME. + Possible modes are "fail", + "warn" (default) and + "ignore". +

+
-t directory
+

+ Chroot to directory so that + include + directives in the configuration file are processed as if + run by a similarly chrooted named. +

+
-w directory
+

+ chdir to directory so that + relative + filenames in master file $INCLUDE directives work. This + is similar to the directory clause in + named.conf. +

+
-D
+

+ Dump zone file in canonical format. + This is always enabled for named-compilezone. +

+
-W mode
+

+ Specify whether to check for non-terminal wildcards. + Non-terminal wildcards are almost always the result of a + failure to understand the wildcard matching algorithm (RFC 1034). + Possible modes are "warn" (default) + and + "ignore". +

+
zonename
+

+ The domain name of the zone being checked. +

+
filename
+

+ The name of the zone file. +

+
+
+
+

RETURN VALUES

+

named-checkzone + returns an exit status of 1 if + errors were detected and 0 otherwise. +

It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use +\fBdig\fR +to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than +\fBdig\fR. +.PP +Although +\fBdig\fR +is normally used with command\-line arguments, it also has a batch mode of operation for reading lookup requests from a file. A brief summary of its command\-line arguments and options is printed when the +\fB\-h\fR +option is given. Unlike earlier versions, the BIND 9 implementation of +\fBdig\fR +allows multiple lookups to be issued from the command line. +.PP +Unless it is told to query a specific name server, +\fBdig\fR +will try each of the servers listed in +\fI/etc/resolv.conf\fR. +.PP +When no command line arguments or options are given, +\fBdig\fR +will perform an NS query for "." (the root). +.PP +It is possible to set per\-user defaults for +\fBdig\fR +via +\fI${HOME}/.digrc\fR. This file is read and any options in it are applied before the command line arguments. +.PP +The IN and CH class names overlap with the IN and CH top level domains names. Either use the +\fB\-t\fR +and +\fB\-c\fR +options to specify the type and class, use the +\fB\-q\fR +the specify the domain name, or use "IN." and "CH." when looking up these top level domains. +.SH "SIMPLE USAGE" +.PP +A typical invocation of +\fBdig\fR +looks like: +.sp +.RS 4 +.nf + dig @server name type +.fi +.RE +.sp +where: +.PP +\fBserver\fR +.RS 4 +is the name or IP address of the name server to query. This can be an IPv4 address in dotted\-decimal notation or an IPv6 address in colon\-delimited notation. When the supplied +\fIserver\fR +argument is a hostname, +\fBdig\fR +resolves that name before querying that name server. If no +\fIserver\fR +argument is provided, +\fBdig\fR +consults +\fI/etc/resolv.conf\fR +and queries the name servers listed there. The reply from the name server that responds is displayed. +.RE +.PP +\fBname\fR +.RS 4 +is the name of the resource record that is to be looked up. +.RE +.PP +\fBtype\fR +.RS 4 +indicates what type of query is required \(em ANY, A, MX, SIG, etc. +\fItype\fR +can be any valid query type. If no +\fItype\fR +argument is supplied, +\fBdig\fR +will perform a lookup for an A record. +.RE +.SH "OPTIONS" +.PP +The +\fB\-b\fR +option sets the source IP address of the query to +\fIaddress\fR. This must be a valid address on one of the host's network interfaces or "0.0.0.0" or "::". An optional port may be specified by appending "#" +.PP +The default query class (IN for internet) is overridden by the +\fB\-c\fR +option. +\fIclass\fR +is any valid class, such as HS for Hesiod records or CH for Chaosnet records. +.PP +The +\fB\-f\fR +option makes +\fBdig \fR +operate in batch mode by reading a list of lookup requests to process from the file +\fIfilename\fR. The file contains a number of queries, one per line. Each entry in the file should be organized in the same way they would be presented as queries to +\fBdig\fR +using the command\-line interface. +.PP +The +\fB\-m\fR +option enables memory usage debugging. +.PP +If a non\-standard port number is to be queried, the +\fB\-p\fR +option is used. +\fIport#\fR +is the port number that +\fBdig\fR +will send its queries instead of the standard DNS port number 53. This option would be used to test a name server that has been configured to listen for queries on a non\-standard port number. +.PP +The +\fB\-4\fR +option forces +\fBdig\fR +to only use IPv4 query transport. The +\fB\-6\fR +option forces +\fBdig\fR +to only use IPv6 query transport. +.PP +The +\fB\-t\fR +option sets the query type to +\fItype\fR. It can be any valid query type which is supported in BIND 9. The default query type is "A", unless the +\fB\-x\fR +option is supplied to indicate a reverse lookup. A zone transfer can be requested by specifying a type of AXFR. When an incremental zone transfer (IXFR) is required, +\fItype\fR +is set to +ixfr=N. The incremental zone transfer will contain the changes made to the zone since the serial number in the zone's SOA record was +\fIN\fR. +.PP +The +\fB\-q\fR +option sets the query name to +\fIname\fR. This useful do distinguish the +\fIname\fR +from other arguments. +.PP +Reverse lookups \(em mapping addresses to names \(em are simplified by the +\fB\-x\fR +option. +\fIaddr\fR +is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address. When this option is used, there is no need to provide the +\fIname\fR, +\fIclass\fR +and +\fItype\fR +arguments. +\fBdig\fR +automatically performs a lookup for a name like +11.12.13.10.in\-addr.arpa +and sets the query type and class to PTR and IN respectively. By default, IPv6 addresses are looked up using nibble format under the IP6.ARPA domain. To use the older RFC1886 method using the IP6.INT domain specify the +\fB\-i\fR +option. Bit string labels (RFC2874) are now experimental and are not attempted. +.PP +To sign the DNS queries sent by +\fBdig\fR +and their responses using transaction signatures (TSIG), specify a TSIG key file using the +\fB\-k\fR +option. You can also specify the TSIG key itself on the command line using the +\fB\-y\fR +option; +\fIhmac\fR +is the type of the TSIG, default HMAC\-MD5, +\fIname\fR +is the name of the TSIG key and +\fIkey\fR +is the actual key. The key is a base\-64 encoded string, typically generated by +\fBdnssec\-keygen\fR(8). Caution should be taken when using the +\fB\-y\fR +option on multi\-user systems as the key can be visible in the output from +\fBps\fR(1) +or in the shell's history file. When using TSIG authentication with +\fBdig\fR, the name server that is queried needs to know the key and algorithm that is being used. In BIND, this is done by providing appropriate +\fBkey\fR +and +\fBserver\fR +statements in +\fInamed.conf\fR. +.SH "QUERY OPTIONS" +.PP +\fBdig\fR +provides a number of query options which affect the way in which lookups are made and the results displayed. Some of these set or reset flag bits in the query header, some determine which sections of the answer get printed, and others determine the timeout and retry strategies. +.PP +Each query option is identified by a keyword preceded by a plus sign (+). Some keywords set or reset an option. These may be preceded by the string +no +to negate the meaning of that keyword. Other keywords assign values to options like the timeout interval. They have the form +\fB+keyword=value\fR. The query options are: +.PP +\fB+[no]tcp\fR +.RS 4 +Use [do not use] TCP when querying name servers. The default behavior is to use UDP unless an AXFR or IXFR query is requested, in which case a TCP connection is used. +.RE +.PP +\fB+[no]vc\fR +.RS 4 +Use [do not use] TCP when querying name servers. This alternate syntax to +\fI+[no]tcp\fR +is provided for backwards compatibility. The "vc" stands for "virtual circuit". +.RE +.PP +\fB+[no]ignore\fR +.RS 4 +Ignore truncation in UDP responses instead of retrying with TCP. By default, TCP retries are performed. +.RE +.PP +\fB+domain=somename\fR +.RS 4 +Set the search list to contain the single domain +\fIsomename\fR, as if specified in a +\fBdomain\fR +directive in +\fI/etc/resolv.conf\fR, and enable search list processing as if the +\fI+search\fR +option were given. +.RE +.PP +\fB+[no]search\fR +.RS 4 +Use [do not use] the search list defined by the searchlist or domain directive in +\fIresolv.conf\fR +(if any). The search list is not used by default. +.RE +.PP +\fB+[no]showsearch\fR +.RS 4 +Perform [do not perform] a search showing intermediate results. +.RE +.PP +\fB+[no]defname\fR +.RS 4 +Deprecated, treated as a synonym for +\fI+[no]search\fR +.RE +.PP +\fB+[no]aaonly\fR +.RS 4 +Sets the "aa" flag in the query. +.RE +.PP +\fB+[no]aaflag\fR +.RS 4 +A synonym for +\fI+[no]aaonly\fR. +.RE +.PP +\fB+[no]adflag\fR +.RS 4 +Set [do not set] the AD (authentic data) bit in the query. The AD bit currently has a standard meaning only in responses, not in queries, but the ability to set the bit in the query is provided for completeness. +.RE +.PP +\fB+[no]cdflag\fR +.RS 4 +Set [do not set] the CD (checking disabled) bit in the query. This requests the server to not perform DNSSEC validation of responses. +.RE +.PP +\fB+[no]cl\fR +.RS 4 +Display [do not display] the CLASS when printing the record. +.RE +.PP +\fB+[no]ttlid\fR +.RS 4 +Display [do not display] the TTL when printing the record. +.RE +.PP +\fB+[no]recurse\fR +.RS 4 +Toggle the setting of the RD (recursion desired) bit in the query. This bit is set by default, which means +\fBdig\fR +normally sends recursive queries. Recursion is automatically disabled when the +\fI+nssearch\fR +or +\fI+trace\fR +query options are used. +.RE +.PP +\fB+[no]nssearch\fR +.RS 4 +When this option is set, +\fBdig\fR +attempts to find the authoritative name servers for the zone containing the name being looked up and display the SOA record that each name server has for the zone. +.RE +.PP +\fB+[no]trace\fR +.RS 4 +Toggle tracing of the delegation path from the root name servers for the name being looked up. Tracing is disabled by default. When tracing is enabled, +\fBdig\fR +makes iterative queries to resolve the name being looked up. It will follow referrals from the root servers, showing the answer from each server that was used to resolve the lookup. +.RE +.PP +\fB+[no]cmd\fR +.RS 4 +Toggles the printing of the initial comment in the output identifying the version of +\fBdig\fR +and the query options that have been applied. This comment is printed by default. +.RE +.PP +\fB+[no]short\fR +.RS 4 +Provide a terse answer.

Each of those queries can be supplied with its own set of flags, options and query options. +.PP +In this case, each +\fIquery\fR +argument represent an individual query in the command\-line syntax described above. Each consists of any of the standard options and flags, the name to be looked up, an optional query type and class and any query options that should be applied to that query. +.PP +A global set of query options, which should be applied to all queries, can also be supplied. These global query options must precede the first tuple of name, class, type, options, flags, and query options supplied on the command line. Any global query options (except the +\fB+[no]cmd\fR +option) can be overridden by a query\-specific set of query options. For example: +.sp +.RS 4 +.nf +dig +qr www.isc.org any \-x 127.0.0.1 isc.org ns +noqr +.fi +.RE +.sp +shows how +\fBdig\fR +could be used from the command line to make three lookups: an ANY query for +www.isc.org, a reverse lookup of 127.0.0.1 and a query for the NS records of +isc.org. A global query option of +\fI+qr\fR +is applied, so that +\fBdig\fR +shows the initial query it made for each lookup. The final query has a local query option of +\fI+noqr\fR +which means that +\fBdig\fR +will not print the initial query when it looks up the NS records for +isc.org. +.SH "IDN SUPPORT" +.PP +If +\fBdig\fR +has been built with IDN (internationalized domain name) support, it can accept and display non\-ASCII domain names. +\fBdig\fR +appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the +\fBIDN_DISABLE\fR +environment variable. The IDN support is disabled if the variable is set when +\fBdig\fR +runs. +.SH "FILES" +.PP +\fI/etc/resolv.conf\fR +.PP +\fI${HOME}/.digrc\fR +.SH "SEE ALSO" +.PP +\fBhost\fR(1), +\fBnamed\fR(8), +\fBdnssec\-keygen\fR(8), +RFC1035. +.SH "BUGS" +.PP +There are probably too many query options. +.SH "COPYRIGHT" +Copyright \(co 2004\-2008 Internet Systems Consortium, Inc.

It performs DNS lookups and + displays the answers that are returned from the name server(s) that + were queried. Most DNS administrators use dig to + troubleshoot DNS problems because of its flexibility, ease of use and + clarity of output. Other lookup tools tend to have less functionality + than dig. + + + + Although dig is normally used with + command-line + arguments, it also has a batch mode of operation for reading lookup + requests from a file. A brief summary of its command-line arguments + and options is printed when the option is given. + Unlike earlier versions, the BIND 9 implementation of + dig allows multiple lookups to be issued + from the + command line. + + + + Unless it is told to query a specific name server, + dig will try each of the servers listed + in + /etc/resolv.conf. + + + + When no command line arguments or options are given, + dig will perform an NS query for "." (the root). + + + + It is possible to set per-user defaults for dig via + ${HOME}/.digrc. This file is read and + any options in it + are applied before the command line arguments. + + + + The IN and CH class names overlap with the IN and CH top level + domains names. Either use the and + options to specify the type and class, + use the the specify the domain name, or + use "IN." and "CH." when looking up these top level domains. + + + + + + SIMPLE USAGE + + + A typical invocation of dig looks like: + dig @server name type + where: + + + + + server + + + is the name or IP address of the name server to query. This can + be an IPv4 + address in dotted-decimal notation or an IPv6 + address in colon-delimited notation. When the supplied + server argument is a + hostname, + dig resolves that name before + querying that name + server. If no server + argument is provided, + dig consults /etc/resolv.conf + and queries the name servers listed there. The reply from the + name + server that responds is displayed. + + + + + + name + + + is the name of the resource record that is to be looked up. + + + + + + type + + + indicates what type of query is required — + ANY, A, MX, SIG, etc. + type can be any valid query + type. If no + type argument is supplied, + dig will perform a lookup for an + A record. + + + + + + + + + + + OPTIONS + + + The option sets the source IP address of the query + to address. This must be a valid + address on + one of the host's network interfaces or "0.0.0.0" or "::". An optional + port + may be specified by appending "#<port>" + + + + The default query class (IN for internet) is overridden by the + option. class is + any valid + class, such as HS for Hesiod records or CH for Chaosnet records. + + + + The option makes dig + operate + in batch mode by reading a list of lookup requests to process from the + file filename. The file contains a + number of + queries, one per line. Each entry in the file should be organized in + the same way they would be presented as queries to + dig using the command-line interface. + + + + The option enables memory usage debugging. + + + + + If a non-standard port number is to be queried, the + option is used. port# is + the port number that dig will send its + queries + instead of the standard DNS port number 53. This option would be used + to test a name server that has been configured to listen for queries + on a non-standard port number. + + + + The option forces dig + to only + use IPv4 query transport. The option forces + dig to only use IPv6 query transport. + + + + The option sets the query type to + type. It can be any valid query type + which is + supported in BIND 9. The default query type is "A", unless the + option is supplied to indicate a reverse lookup. + A zone transfer can be requested by specifying a type of AXFR. When + an incremental zone transfer (IXFR) is required, + type is set to ixfr=N. + The incremental zone transfer will contain the changes made to the zone + since the serial number in the zone's SOA record was + N. + + + + The option sets the query name to + name. This useful do distinguish the + name from other arguments. + + + + Reverse lookups — mapping addresses to names — are simplified by the + option. addr is + an IPv4 + address in dotted-decimal notation, or a colon-delimited IPv6 address. + When this option is used, there is no need to provide the + name, class and + type arguments. dig + automatically performs a lookup for a name like + 11.12.13.10.in-addr.arpa and sets the + query type and + class to PTR and IN respectively. By default, IPv6 addresses are + looked up using nibble format under the IP6.ARPA domain. + To use the older RFC1886 method using the IP6.INT domain + specify the option. Bit string labels (RFC2874) + are now experimental and are not attempted. + + + + To sign the DNS queries sent by dig and + their + responses using transaction signatures (TSIG), specify a TSIG key file + using the option. You can also specify the TSIG + key itself on the command line using the option; + hmac is the type of the TSIG, default HMAC-MD5, + name is the name of the TSIG key and + key is the actual key. The key is a + base-64 + encoded string, typically generated by + + dnssec-keygen8 + . + + Caution should be taken when using the option on + multi-user systems as the key can be visible in the output from + + ps1 + + or in the shell's history file. When + using TSIG authentication with dig, the name + server that is queried needs to know the key and algorithm that is + being used. In BIND, this is done by providing appropriate + key and server statements in + named.conf. + + + + + + QUERY OPTIONS + + dig + provides a number of query options which affect + the way in which lookups are made and the results displayed. Some of + these set or reset flag bits in the query header, some determine which + sections of the answer get printed, and others determine the timeout + and retry strategies. + + + + Each query option is identified by a keyword preceded by a plus sign + (+). Some keywords set or reset an + option. These may be preceded + by the string no to negate the meaning of + that keyword. Other + keywords assign values to options like the timeout interval. They + have the form . + The query options are: + + + + + + + + Use [do not use] TCP when querying name servers. The default + behavior is to use UDP unless an AXFR or IXFR query is + requested, in + which case a TCP connection is used. + + + + + + + + + Use [do not use] TCP when querying name servers. This alternate + syntax to +[no]tcp is + provided for backwards + compatibility. The "vc" stands for "virtual circuit". + + + + + + + + + Ignore truncation in UDP responses instead of retrying with TCP. + By + default, TCP retries are performed. + + + + + + + + + Set the search list to contain the single domain + somename, as if specified in + a + domain directive in + /etc/resolv.conf, and enable + search list + processing as if the +search + option were given. + + + + + + + + + Use [do not use] the search list defined by the searchlist or + domain + directive in resolv.conf (if + any). + The search list is not used by default. + + + + + + + + + Perform [do not perform] a search showing intermediate + results. + + + + + + + + + Deprecated, treated as a synonym for +[no]search + + + + + + + + + Sets the "aa" flag in the query. + + + + + + + + + A synonym for +[no]aaonly. + + + + + + + + + Set [do not set] the AD (authentic data) bit in the query. The + AD bit + currently has a standard meaning only in responses, not in + queries, + but the ability to set the bit in the query is provided for + completeness. + + + + + + + + + Set [do not set] the CD (checking disabled) bit in the query. + This + requests the server to not perform DNSSEC validation of + responses. + + + + + + + + + Display [do not display] the CLASS when printing the record. + + + + + + + + + Display [do not display] the TTL when printing the record. + + + + + + + + + Toggle the setting of the RD (recursion desired) bit in the + query. + This bit is set by default, which means dig + normally sends recursive queries. Recursion is automatically + disabled + when the +nssearch or + +trace query options are + used. + + + + + + + + + When this option is set, dig + attempts to find the + authoritative name servers for the zone containing the name + being + looked up and display the SOA record that each name server has + for the + zone. + + + + + + + + + Toggle tracing of the delegation path from the root name servers + for + the name being looked up. Tracing is disabled by default. When + tracing is enabled, dig makes + iterative queries to + resolve the name being looked up. It will follow referrals from + the + root servers, showing the answer from each server that was used + to + resolve the lookup. + + + + + + + + + Toggles the printing of the initial comment in the output + identifying + the version of dig and the query + options that have + been applied.

The default + timeout is 5 seconds. + An attempt to set T to less + than 1 will result + in a query timeout of 1 second being applied. + + + + + + + + + Sets the number of times to try UDP queries to server to + T instead of the default, 3. + If + T is less than or equal to + zero, the number of + tries is silently rounded up to 1. + + + + + + + + + Sets the number of times to retry UDP queries to server to + T instead of the default, 2. + Unlike + +tries, this does not include + the initial + query. + + + + + + + + + Set the number of dots that have to appear in + name to D for it to be + considered absolute.

The + default is + to not try the next server which is the reverse of normal stub + resolver + behavior. + + + + + + + + + Attempt to display the contents of messages which are malformed. + The default is to not display malformed answers. + + + + + + + + + Requests DNSSEC records be sent by setting the DNSSEC OK bit + (DO) + in the OPT record in the additional section of the query. + + + + + + + + + Chase DNSSEC signature chains.

Each of those + queries can be supplied with its own set of flags, options and query + options. + + + + In this case, each query argument + represent an + individual query in the command-line syntax described above. Each + consists of any of the standard options and flags, the name to be + looked up, an optional query type and class and any query options that + should be applied to that query. + + + + A global set of query options, which should be applied to all queries, + can also be supplied. These global query options must precede the + first tuple of name, class, type, options, flags, and query options + supplied on the command line. Any global query options (except + the option) can be + overridden by a query-specific set of query options. For example: + +dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr + + shows how dig could be used from the + command line + to make three lookups: an ANY query for www.isc.org, a + reverse lookup of 127.0.0.1 and a query for the NS records of + isc.org. + + A global query option of +qr is + applied, so + that dig shows the initial query it made + for each + lookup. The final query has a local query option of + +noqr which means that dig + will not print the initial query when it looks up the NS records for + isc.org. + + + + + + IDN SUPPORT + + If dig has been built with IDN (internationalized + domain name) support, it can accept and display non-ASCII domain names. + dig appropriately converts character encoding of + domain name before sending a request to DNS server or displaying a + reply from the server. + If you'd like to turn off the IDN support for some reason, defines + the IDN_DISABLE environment variable. + The IDN support is disabled if the variable is set when + dig runs. + + + + + FILES + /etc/resolv.conf + + ${HOME}/.digrc + + + + + SEE ALSO + + host1 + , + + named8 + , + + dnssec-keygen8 + , + RFC1035. + + + + + BUGS + + There are probably too many query options. + + + diff --git a/bin/dig/dig.html b/bin/dig/dig.html new file mode 100644 index 0000000..7c79c6e --- /dev/null +++ b/bin/dig/dig.html @@ -0,0 +1,637 @@ + + + + + +dig + + +

DESCRIPTION

+

dig + (domain information groper) is a flexible tool + for interrogating DNS name servers. It performs DNS lookups and + displays the answers that are returned from the name server(s) that + were queried. Most DNS administrators use dig to + troubleshoot DNS problems because of its flexibility, ease of use and + clarity of output. Other lookup tools tend to have less functionality + than dig. +

+

+ Although dig is normally used with + command-line + arguments, it also has a batch mode of operation for reading lookup + requests from a file. A brief summary of its command-line arguments + and options is printed when the -h option is given. + Unlike earlier versions, the BIND 9 implementation of + dig allows multiple lookups to be issued + from the + command line. +

+

+ Unless it is told to query a specific name server, + dig will try each of the servers listed + in + /etc/resolv.conf. +

+

+ When no command line arguments or options are given, + dig will perform an NS query for "." (the root). +

+

+ It is possible to set per-user defaults for dig via + ${HOME}/.digrc. This file is read and + any options in it + are applied before the command line arguments. +

+

+ The IN and CH class names overlap with the IN and CH top level + domains names. Either use the -t and + -c options to specify the type and class, + use the -q the specify the domain name, or + use "IN." and "CH." when looking up these top level domains. +

+
+
+

SIMPLE USAGE

+

+ A typical invocation of dig looks like: +

+
 dig @server name type
+

+ where: + +

+
+
server
+

+ is the name or IP address of the name server to query. This can + be an IPv4 + address in dotted-decimal notation or an IPv6 + address in colon-delimited notation. When the supplied + server argument is a + hostname, + dig resolves that name before + querying that name + server. If no server + argument is provided, + dig consults /etc/resolv.conf + and queries the name servers listed there. The reply from the + name + server that responds is displayed. +

+
name
+

+ is the name of the resource record that is to be looked up. +

+
type
+

+ indicates what type of query is required — + ANY, A, MX, SIG, etc. + type can be any valid query + type. If no + type argument is supplied, + dig will perform a lookup for an + A record. +

+
+

+

+
+
+

OPTIONS

+

+ The -b option sets the source IP address of the query + to address. This must be a valid + address on + one of the host's network interfaces or "0.0.0.0" or "::". An optional + port + may be specified by appending "#<port>" +

+

+ The default query class (IN for internet) is overridden by the + -c option. class is + any valid + class, such as HS for Hesiod records or CH for Chaosnet records. +

+

+ The -f option makes dig + operate + in batch mode by reading a list of lookup requests to process from the + file filename. The file contains a + number of + queries, one per line. Each entry in the file should be organized in + the same way they would be presented as queries to + dig using the command-line interface. +

+

+ The -m option enables memory usage debugging. + +

+

+ If a non-standard port number is to be queried, the + -p option is used. port# is + the port number that dig will send its + queries + instead of the standard DNS port number 53. This option would be used + to test a name server that has been configured to listen for queries + on a non-standard port number. +

+

+ The -4 option forces dig + to only + use IPv4 query transport. The -6 option forces + dig to only use IPv6 query transport. +

+

+ The -t option sets the query type to + type. It can be any valid query type + which is + supported in BIND 9. The default query type is "A", unless the + -x option is supplied to indicate a reverse lookup. + A zone transfer can be requested by specifying a type of AXFR. When + an incremental zone transfer (IXFR) is required, + type is set to ixfr=N. + The incremental zone transfer will contain the changes made to the zone + since the serial number in the zone's SOA record was + N. +

+

+ The -q option sets the query name to + name. This useful do distinguish the + name from other arguments. +

+

+ Reverse lookups — mapping addresses to names — are simplified by the + -x option. addr is + an IPv4 + address in dotted-decimal notation, or a colon-delimited IPv6 address. + When this option is used, there is no need to provide the + name, class and + type arguments. dig + automatically performs a lookup for a name like + 11.12.13.10.in-addr.arpa and sets the + query type and + class to PTR and IN respectively. By default, IPv6 addresses are + looked up using nibble format under the IP6.ARPA domain. + To use the older RFC1886 method using the IP6.INT domain + specify the -i option. Bit string labels (RFC2874) + are now experimental and are not attempted. +

+

+ To sign the DNS queries sent by dig and + their + responses using transaction signatures (TSIG), specify a TSIG key file + using the -k option. You can also specify the TSIG + key itself on the command line using the -y option; + hmac is the type of the TSIG, default HMAC-MD5, + name is the name of the TSIG key and + key is the actual key. The key is a + base-64 + encoded string, typically generated by + dnssec-keygen(8). + + Caution should be taken when using the -y option on + multi-user systems as the key can be visible in the output from + ps(1) + or in the shell's history file. When + using TSIG authentication with dig, the name + server that is queried needs to know the key and algorithm that is + being used. In BIND, this is done by providing appropriate + key and server statements in + named.conf. +

+
+
+

QUERY OPTIONS

+

dig + provides a number of query options which affect + the way in which lookups are made and the results displayed. Some of + these set or reset flag bits in the query header, some determine which + sections of the answer get printed, and others determine the timeout + and retry strategies. +

+

+ Each query option is identified by a keyword preceded by a plus sign + (+). Some keywords set or reset an + option. These may be preceded + by the string no to negate the meaning of + that keyword. Other + keywords assign values to options like the timeout interval. They + have the form +keyword=value. + The query options are: + +

+
+
+[no]tcp
+

+ Use [do not use] TCP when querying name servers. The default + behavior is to use UDP unless an AXFR or IXFR query is + requested, in + which case a TCP connection is used. +

+
+[no]vc
+

+ Use [do not use] TCP when querying name servers. This alternate + syntax to +[no]tcp is + provided for backwards + compatibility. The "vc" stands for "virtual circuit". +

+
+[no]ignore
+

+ Ignore truncation in UDP responses instead of retrying with TCP. + By + default, TCP retries are performed. +

+
+domain=somename
+

+ Set the search list to contain the single domain + somename, as if specified in + a + domain directive in + /etc/resolv.conf, and enable + search list + processing as if the +search + option were given. +

+
+[no]search
+

+ Use [do not use] the search list defined by the searchlist or + domain + directive in resolv.conf (if + any). + The search list is not used by default. +

+
+[no]showsearch
+

+ Perform [do not perform] a search showing intermediate + results. +

+
+[no]defname
+

+ Deprecated, treated as a synonym for +[no]search +

+
+[no]aaonly
+

+ Sets the "aa" flag in the query. +

+
+[no]aaflag
+

+ A synonym for +[no]aaonly. +

+
+[no]adflag
+

+ Set [do not set] the AD (authentic data) bit in the query. The + AD bit + currently has a standard meaning only in responses, not in + queries, + but the ability to set the bit in the query is provided for + completeness. +

+
+[no]cdflag
+

+ Set [do not set] the CD (checking disabled) bit in the query. + This + requests the server to not perform DNSSEC validation of + responses. +

+
+[no]cl
+

+ Display [do not display] the CLASS when printing the record. +

+
+[no]ttlid
+

+ Display [do not display] the TTL when printing the record. +

+
+[no]recurse
+

+ Toggle the setting of the RD (recursion desired) bit in the + query. + This bit is set by default, which means dig + normally sends recursive queries. Recursion is automatically + disabled + when the +nssearch or + +trace query options are + used. +

+
+[no]nssearch
+

+ When this option is set, dig + attempts to find the + authoritative name servers for the zone containing the name + being + looked up and display the SOA record that each name server has + for the + zone. +

+
+[no]trace
+

+ Toggle tracing of the delegation path from the root name servers + for + the name being looked up. Tracing is disabled by default. When + tracing is enabled, dig makes + iterative queries to + resolve the name being looked up. It will follow referrals from + the + root servers, showing the answer from each server that was used + to + resolve the lookup. +

+
+[no]cmd
+

+ Toggles the printing of the initial comment in the output + identifying + the version of dig and the query + options that have + been applied. This comment is printed by default. +

+
+[no]short
+

+ Provide a terse answer. The default is to print the answer in a + verbose form. +

+
+[no]identify
+

+ Show [or do not show] the IP address and port number that + supplied the + answer when the +short option + is enabled. If + short form answers are requested, the default is not to show the + source address and port number of the server that provided the + answer. +

+
+[no]comments
+

+ Toggle the display of comment lines in the output. The default + is to + print comments. +

+
+[no]stats
+

+ This query option toggles the printing of statistics: when the + query + was made, the size of the reply and so on. The default + behavior is + to print the query statistics. +

+
+[no]qr
+

+ Print [do not print] the query as it is sent. + By default, the query is not printed. +

+
+[no]question
+

+ Print [do not print] the question section of a query when an + answer is + returned. The default is to print the question section as a + comment. +

+
+[no]answer
+

+ Display [do not display] the answer section of a reply. The + default + is to display it. +

+
+[no]authority
+

+ Display [do not display] the authority section of a reply. The + default is to display it. +

+
+[no]additional
+

+ Display [do not display] the additional section of a reply. + The default is to display it. +

+
+[no]all
+

+ Set or clear all display flags. +

+
+time=T
+

+ + Sets the timeout for a query to + T seconds. The default + timeout is 5 seconds. + An attempt to set T to less + than 1 will result + in a query timeout of 1 second being applied. +

+
+tries=T
+

+ Sets the number of times to try UDP queries to server to + T instead of the default, 3. + If + T is less than or equal to + zero, the number of + tries is silently rounded up to 1. +

+
+retry=T
+

+ Sets the number of times to retry UDP queries to server to + T instead of the default, 2. + Unlike + +tries, this does not include + the initial + query. +

+
+ndots=D
+

+ Set the number of dots that have to appear in + name to D for it to be + considered absolute. The default value is that defined using + the + ndots statement in /etc/resolv.conf, or 1 if no + ndots statement is present. Names with fewer dots are + interpreted as + relative names and will be searched for in the domains listed in + the + search or domain directive in + /etc/resolv.conf. +

+
+bufsize=B
+

+ Set the UDP message buffer size advertised using EDNS0 to + B bytes. The maximum and minimum sizes + of this buffer are 65535 and 0 respectively. Values outside + this range are rounded up or down appropriately. + Values other than zero will cause a EDNS query to be sent. +

+
+edns=#
+

+ Specify the EDNS version to query with. Valid values + are 0 to 255. Setting the EDNS version will cause a + EDNS query to be sent. +noedns clears the + remembered EDNS version. +

+
+[no]multiline
+

+ Print records like the SOA records in a verbose multi-line + format with human-readable comments. The default is to print + each record on a single line, to facilitate machine parsing + of the dig output. +

+
+[no]fail
+

+ Do not try the next server if you receive a SERVFAIL. The + default is + to not try the next server which is the reverse of normal stub + resolver + behavior. +

+
+[no]besteffort
+

+ Attempt to display the contents of messages which are malformed. + The default is to not display malformed answers. +

+
+[no]dnssec
+

+ Requests DNSSEC records be sent by setting the DNSSEC OK bit + (DO) + in the OPT record in the additional section of the query. +

+
+[no]sigchase
+

+ Chase DNSSEC signature chains. Requires dig be compiled with + -DDIG_SIGCHASE. +

+
+trusted-key=####
+
+

+ Specifies a file containing trusted keys to be used with + +sigchase. Each DNSKEY record must be + on its own line. +

+

+ If not specified dig will look for + /etc/trusted-key.key then + trusted-key.key in the current directory. +

+

+ Requires dig be compiled with -DDIG_SIGCHASE. +

+
+
+[no]topdown
+

+ When chasing DNSSEC signature chains perform a top-down + validation. + Requires dig be compiled with -DDIG_SIGCHASE. +

+
+[no]nsid
+

+ Include an EDNS name server ID request when sending a query. +

+
+

+ +

+
+
+

MULTIPLE QUERIES

+

+ The BIND 9 implementation of dig + supports + specifying multiple queries on the command line (in addition to + supporting the -f batch file option). Each of those + queries can be supplied with its own set of flags, options and query + options. +

+

+ In this case, each query argument + represent an + individual query in the command-line syntax described above. Each + consists of any of the standard options and flags, the name to be + looked up, an optional query type and class and any query options that + should be applied to that query. +

+

+ A global set of query options, which should be applied to all queries, + can also be supplied. These global query options must precede the + first tuple of name, class, type, options, flags, and query options + supplied on the command line. Any global query options (except + the +[no]cmd option) can be + overridden by a query-specific set of query options. For example: +

+
+dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
+
+

+ shows how dig could be used from the + command line + to make three lookups: an ANY query for www.isc.org, a + reverse lookup of 127.0.0.1 and a query for the NS records of + isc.org. + + A global query option of +qr is + applied, so + that dig shows the initial query it made + for each + lookup. The final query has a local query option of + +noqr which means that dig + will not print the initial query when it looks up the NS records for + isc.org. +

+
+
+

IDN SUPPORT

+

+ If dig has been built with IDN (internationalized + domain name) support, it can accept and display non-ASCII domain names. + dig appropriately converts character encoding of + domain name before sending a request to DNS server or displaying a + reply from the server. + If you'd like to turn off the IDN support for some reason, defines + the IDN_DISABLE environment variable. + The IDN support is disabled if the variable is set when + dig runs. +

It is normally used to convert names to IP addresses and vice versa. When no arguments or options are given, +\fBhost\fR +prints a short summary of its command line arguments and options. +.PP +\fIname\fR +is the domain name that is to be looked up. It can also be a dotted\-decimal IPv4 address or a colon\-delimited IPv6 address, in which case +\fBhost\fR +will by default perform a reverse lookup for that address. +\fIserver\fR +is an optional argument which is either the name or IP address of the name server that +\fBhost\fR +should query instead of the server or servers listed in +\fI/etc/resolv.conf\fR. +.PP +The +\fB\-a\fR +(all) option is equivalent to setting the +\fB\-v\fR +option and asking +\fBhost\fR +to make a query of type ANY. +.PP +When the +\fB\-C\fR +option is used, +\fBhost\fR +will attempt to display the SOA records for zone +\fIname\fR +from all the listed authoritative name servers for that zone. The list of name servers is defined by the NS records that are found for the zone. +.PP +The +\fB\-c\fR +option instructs to make a DNS query of class +\fIclass\fR. This can be used to lookup Hesiod or Chaosnet class resource records. The default class is IN (Internet). +.PP +Verbose output is generated by +\fBhost\fR +when the +\fB\-d\fR +or +\fB\-v\fR +option is used. The two options are equivalent. They have been provided for backwards compatibility. In previous versions, the +\fB\-d\fR +option switched on debugging traces and +\fB\-v\fR +enabled verbose output. +.PP +List mode is selected by the +\fB\-l\fR +option. This makes +\fBhost\fR +perform a zone transfer for zone +\fIname\fR. Transfer the zone printing out the NS, PTR and address records (A/AAAA). If combined with +\fB\-a\fR +all records will be printed. +.PP +The +\fB\-i\fR +option specifies that reverse lookups of IPv6 addresses should use the IP6.INT domain as defined in RFC1886. The default is to use IP6.ARPA. +.PP +The +\fB\-N\fR +option sets the number of dots that have to be in +\fIname\fR +for it to be considered absolute. The default value is that defined using the ndots statement in +\fI/etc/resolv.conf\fR, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the +\fBsearch\fR +or +\fBdomain\fR +directive in +\fI/etc/resolv.conf\fR. +.PP +The number of UDP retries for a lookup can be changed with the +\fB\-R\fR +option. +\fInumber\fR +indicates how many times +\fBhost\fR +will repeat a query that does not get answered. The default number of retries is 1. If +\fInumber\fR +is negative or zero, the number of retries will default to 1. +.PP +Non\-recursive queries can be made via the +\fB\-r\fR +option. Setting this option clears the +\fBRD\fR +\(em recursion desired \(em bit in the query which +\fBhost\fR +makes. This should mean that the name server receiving the query will not attempt to resolve +\fIname\fR. The +\fB\-r\fR +option enables +\fBhost\fR +to mimic the behavior of a name server by making non\-recursive queries and expecting to receive answers to those queries that are usually referrals to other name servers. +.PP +By default +\fBhost\fR +uses UDP when making queries. The +\fB\-T\fR +option makes it use a TCP connection when querying the name server. TCP will be automatically selected for queries that require it, such as zone transfer (AXFR) requests. +.PP +The +\fB\-4\fR +option forces +\fBhost\fR +to only use IPv4 query transport. The +\fB\-6\fR +option forces +\fBhost\fR +to only use IPv6 query transport. +.PP +The +\fB\-t\fR +option is used to select the query type. +\fItype\fR +can be any recognized query type: CNAME, NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified, +\fBhost\fR +automatically selects an appropriate query type. By default it looks for A, AAAA, and MX records, but if the +\fB\-C\fR +option was given, queries will be made for SOA records, and if +\fIname\fR +is a dotted\-decimal IPv4 address or colon\-delimited IPv6 address, +\fBhost\fR +will query for PTR records. If a query type of IXFR is chosen the starting serial number can be specified by appending an equal followed by the starting serial number (e.g. \-t IXFR=12345678). +.PP +The time to wait for a reply can be controlled through the +\fB\-W\fR +and +\fB\-w\fR +options. The +\fB\-W\fR +option makes +\fBhost\fR +wait for +\fIwait\fR +seconds. If +\fIwait\fR +is less than one, the wait interval is set to one second. When the +\fB\-w\fR +option is used, +\fBhost\fR +will effectively wait forever for a reply. The time to wait for a response will be set to the number of seconds given by the hardware's maximum value for an integer quantity. +.PP +The +\fB\-s\fR +option tells +\fBhost\fR +\fInot\fR +to send the query to the next nameserver if any server responds with a SERVFAIL response, which is the reverse of normal stub resolver behavior. +.PP +The +\fB\-m\fR +can be used to set the memory usage debugging flags +\fIrecord\fR, +\fIusage\fR +and +\fItrace\fR. +.SH "IDN SUPPORT" +.PP +If +\fBhost\fR +has been built with IDN (internationalized domain name) support, it can accept and display non\-ASCII domain names. +\fBhost\fR +appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the +\fBIDN_DISABLE\fR +environment variable. The IDN support is disabled if the variable is set when +\fBhost\fR +runs. +.SH "FILES" +.PP +\fI/etc/resolv.conf\fR +.SH "SEE ALSO" +.PP +\fBdig\fR(1), +\fBnamed\fR(8). +.SH "COPYRIGHT" +Copyright \(co 2004, 2005, 2007, 2008 Internet Systems Consortium, Inc.

DESCRIPTION

+

host + is a simple utility for performing DNS lookups. + It is normally used to convert names to IP addresses and vice versa. + When no arguments or options are given, + host + prints a short summary of its command line arguments and options. +

+

name is the domain name that is to be + looked + up. It can also be a dotted-decimal IPv4 address or a colon-delimited + IPv6 address, in which case host will by + default + perform a reverse lookup for that address. + server is an optional argument which + is either + the name or IP address of the name server that host + should query instead of the server or servers listed in + /etc/resolv.conf. +

+

+ The -a (all) option is equivalent to setting the + -v option and asking host to make + a query of type ANY. +

+

+ When the -C option is used, host + will attempt to display the SOA records for zone + name from all the listed + authoritative name + servers for that zone. The list of name servers is defined by the NS + records that are found for the zone. +

+

+ The -c option instructs to make a DNS query of class + class. This can be used to lookup + Hesiod or + Chaosnet class resource records. The default class is IN (Internet). +

+

+ Verbose output is generated by host when + the + -d or -v option is used. The two + options are equivalent. They have been provided for backwards + compatibility. In previous versions, the -d option + switched on debugging traces and -v enabled verbose + output. +

+

+ List mode is selected by the -l option. This makes + host perform a zone transfer for zone + name. Transfer the zone printing out + the NS, PTR + and address records (A/AAAA). If combined with -a + all records will be printed. +

+

+ The -i + option specifies that reverse lookups of IPv6 addresses should + use the IP6.INT domain as defined in RFC1886. + The default is to use IP6.ARPA. +

+

+ The -N option sets the number of dots that have to be + in name for it to be considered + absolute. The + default value is that defined using the ndots statement in + /etc/resolv.conf, or 1 if no ndots + statement is + present. Names with fewer dots are interpreted as relative names and + will be searched for in the domains listed in the search + or domain directive in + /etc/resolv.conf. +

+

+ The number of UDP retries for a lookup can be changed with the + -R option. number + indicates + how many times host will repeat a query + that does + not get answered. The default number of retries is 1. If + number is negative or zero, the + number of + retries will default to 1. +

+

+ Non-recursive queries can be made via the -r option. + Setting this option clears the RD — recursion + desired — bit in the query which host makes. + This should mean that the name server receiving the query will not + attempt to resolve name. The + -r option enables host + to mimic + the behavior of a name server by making non-recursive queries and + expecting to receive answers to those queries that are usually + referrals to other name servers. +

+

+ By default host uses UDP when making + queries. The + -T option makes it use a TCP connection when querying + the name server. TCP will be automatically selected for queries that + require it, such as zone transfer (AXFR) requests. +

+

+ The -4 option forces host to only + use IPv4 query transport. The -6 option forces + host to only use IPv6 query transport. +

+

+ The -t option is used to select the query type. + type can be any recognized query + type: CNAME, + NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified, + host automatically selects an appropriate + query + type. By default it looks for A, AAAA, and MX records, but if the + -C option was given, queries will be made for SOA + records, and if name is a + dotted-decimal IPv4 + address or colon-delimited IPv6 address, host will + query for PTR records. If a query type of IXFR is chosen the starting + serial number can be specified by appending an equal followed by the + starting serial number (e.g. -t IXFR=12345678). +

+

+ The time to wait for a reply can be controlled through the + -W and -w options. The + -W option makes host + wait for + wait seconds. If wait + is less than one, the wait interval is set to one second. When the + -w option is used, host + will + effectively wait forever for a reply. The time to wait for a response + will be set to the number of seconds given by the hardware's maximum + value for an integer quantity. +

+

+ The -s option tells host + not to send the query to the next nameserver + if any server responds with a SERVFAIL response, which is the + reverse of normal stub resolver behavior. +

+

+ The -m can be used to set the memory usage debugging + flags + record, usage and + trace. +

+
+
+

IDN SUPPORT

+

+ If host has been built with IDN (internationalized + domain name) support, it can accept and display non-ASCII domain names. + host appropriately converts character encoding of + domain name before sending a request to DNS server or displaying a + reply from the server. + If you'd like to turn off the IDN support for some reason, defines + the IDN_DISABLE environment variable. + The IDN support is disabled if the variable is set when + host runs. +

Non\-interactive mode is used to print just the name and requested information for a host or domain. +.SH "ARGUMENTS" +.PP +Interactive mode is entered in the following cases: +.TP 4 +1. +when no arguments are given (the default name server will be used) +.TP 4 +2. +when the first argument is a hyphen (\-) and the second argument is the host name or Internet address of a name server. +.sp +.RE +.PP +Non\-interactive mode is used when the name or Internet address of the host to be looked up is given as the first argument.

("ISC") + + + + + + nslookup + + name | - + server + + + + + DESCRIPTION + Nslookup + is a program to query Internet domain name servers. Nslookup + has two modes: interactive and non-interactive. Interactive mode allows + the user to query name servers for information about various hosts and + domains or to print a list of hosts in a domain. Non-interactive mode + is + used to print just the name and requested information for a host or + domain. + + + + + ARGUMENTS + + Interactive mode is entered in the following cases: + + + + when no arguments are given (the default name server will be used) + + + + + when the first argument is a hyphen (-) and the second argument is + the host name or Internet address of a name server. + + + + + + + Non-interactive mode is used when the name or Internet address of the + host to be looked up is given as the first argument. The optional second + argument specifies the host name or address of a name server. + + + + Options can also be specified on the command line if they precede the + arguments and are prefixed with a hyphen. For example, to + change the default query type to host information, and the initial + timeout to 10 seconds, type: + + +nslookup -query=hinfo -timeout=10 + + + + + + + + INTERACTIVE COMMANDS + + + host server + + + Look up information for host using the current default server or + using server, if specified. If host is an Internet address and + the query type is A or PTR, the name of the host is returned. + If host is a name and does not have a trailing period, the + search list is used to qualify the name. + + + + To look up a host not in the current domain, append a period to + the name. + + + + + + server domain + + + + + + lserver domain + + + Change the default server to domain; lserver uses the initial + server to look up information about domain, while server uses + the current default server.

Name

+

nslookup — query Internet name servers interactively

+
+
+

Synopsis

+

nslookup [-option] [name | -] [server]

+
+
+

DESCRIPTION

+

Nslookup + is a program to query Internet domain name servers. Nslookup + has two modes: interactive and non-interactive. Interactive mode allows + the user to query name servers for information about various hosts and + domains or to print a list of hosts in a domain. Non-interactive mode + is + used to print just the name and requested information for a host or + domain. +

+
+
+

ARGUMENTS

+

+ Interactive mode is entered in the following cases: +

+
    +

  1. + when no arguments are given (the default name server will be used) +

    2. +

  2. + when the first argument is a hyphen (-) and the second argument is + the host name or Internet address of a name server. +

    3. +
+

+

+

+ Non-interactive mode is used when the name or Internet address of the + host to be looked up is given as the first argument. The optional second + argument specifies the host name or address of a name server. +

+

+ Options can also be specified on the command line if they precede the + arguments and are prefixed with a hyphen. For example, to + change the default query type to host information, and the initial + timeout to 10 seconds, type: +

+
+nslookup -query=hinfo  -timeout=10
+
+

+

+
+
+

INTERACTIVE COMMANDS

+
+
host [server]
+
+

+ Look up information for host using the current default server or + using server, if specified. If host is an Internet address and + the query type is A or PTR, the name of the host is returned. + If host is a name and does not have a trailing period, the + search list is used to qualify the name. +

+

+ To look up a host not in the current domain, append a period to + the name. +

+
+
server domain
+

+
lserver domain
+

+ Change the default server to domain; lserver uses the initial + server to look up information about domain, while server uses + the current default server. If an authoritative answer can't be + found, the names of servers that might have the answer are + returned. +

+
set + keyword[=value]
+
+

+ This command is used to change state information that affects + the lookups. Valid keywords are: +

+
+
all
+

+ Prints the current values of the frequently used + options to set. + Information about the current default + server and host is also printed. +

+
class=value
+
+

+ Change the query class to one of: +

+
+
IN
+

+ the Internet class +

+
CH
+

+ the Chaos class +

+
HS
+

+ the Hesiod class +

+
ANY
+

+ wildcard +

+
+

+ The class specifies the protocol group of the information. + +

+

+ (Default = IN; abbreviation = cl) +

+
+
+ [no]debug
+
+

+ Turn on or off the display of the full response packet and + any intermediate response packets when searching. +

+

+ (Default = nodebug; abbreviation = [no]deb) +

+
+
+ [no]d2
+
+

+ Turn debugging mode on or off. This displays more about + what nslookup is doing. +

+

+ (Default = nod2) +

+
+
domain=name
+

+ Sets the search list to name. +

+
+ [no]search
+
+

+ If the lookup request contains at least one period but + doesn't end with a trailing period, append the domain + names in the domain search list to the request until an + answer is received. +

+

+ (Default = search) +

+
+
port=value
+
+

+ Change the default TCP/UDP name server port to value. +

+

+ (Default = 53; abbreviation = po) +

+
+
querytype=value
+

+
type=value
+
+

+ Change the type of the information query. +

+

+ (Default = A; abbreviations = q, ty) +

+
+
+ [no]recurse
+
+

+ Tell the name server to query other servers if it does not + have the + information. +

+

+ (Default = recurse; abbreviation = [no]rec) +

+
+
retry=number
+

+ Set the number of retries to number. +

+
timeout=number
+

+ Change the initial timeout interval for waiting for a + reply to number seconds. +

+
+ [no]vc
+
+

+ Always use a virtual circuit when sending requests to the + server. +

+

+ (Default = novc) +

+
+
+ [no]fail
+
+

+ Try the next nameserver if a nameserver responds with + SERVFAIL or a referral (nofail) or terminate query + (fail) on such a response. +

+

+ (Default = nofail) +

+

Name

+

dnssec-dsfromkey — DNSSEC DS RR generation tool

+
+
+

Synopsis

+

dnssec-dsfromkey [-v level] [-1] [-2] [-a alg] {keyfile}

+

dnssec-dsfromkey {-s} [-v level] [-1] [-2] [-a alg] [-c class] [-d dir] {dnsname}

+
+
+

DESCRIPTION

+

dnssec-dsfromkey + outputs the Delegation Signer (DS) resource record (RR), as defined in + RFC 3658 and RFC 4509, for the given key(s). +

+
+
+

OPTIONS

+
+
-1
+

+ Use SHA-1 as the digest algorithm (the default is to use + both SHA-1 and SHA-256). +

+
-2
+

+ Use SHA-256 as the digest algorithm. +

+
-a algorithm
+

+ Select the digest algorithm. The value of + algorithm must be one of SHA-1 (SHA1) or + SHA-256 (SHA256). These values are case insensitive. +

+
-v level
+

+ Sets the debugging level. +

+
-s
+

+ Keyset mode: in place of the keyfile name, the argument is + the DNS domain name of a keyset file. Following options make sense + only in this mode. +

+
-c class
+

+ Specifies the DNS class (default is IN), useful only + in the keyset mode. +

+
-d directory
+

+ Look for keyset files in + directory as the directory, ignored when + not in the keyset mode. +

+
+
+
+

EXAMPLE

+

+ To build the SHA-256 DS RR from the + Kexample.com.+003+26160 + keyfile name, the following command would be issued: +

+

dnssec-dsfromkey -2 Kexample.com.+003+26160 +

+

+ The command would print something like: +

+

example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94 +

+
+
+

FILES

+

+ The keyfile can be designed by the key identification + Knnnn.+aaa+iiiii or the full file name + Knnnn.+aaa+iiiii.key as generated by + dnssec-keygen(8). +

+

+ The keyset file name is built from the directory, + the string keyset- and the + dnsname. +

+
+
+

CAVEAT

+

+ A keyfile error can give a "file not found" even if the file exists. +

+
+
+

dnssec-keyfromlabel — DNSSEC key generation tool

+
+
+

Synopsis

+

dnssec-keyfromlabel {-a algorithm} {-l label} [-c class] [-f flag] [-k] [-n nametype] [-p protocol] [-t type] [-v level] {name}

+
+
+

DESCRIPTION

+

dnssec-keyfromlabel + gets keys with the given label from a crypto hardware and builds + key files for DNSSEC (Secure DNS), as defined in RFC 2535 + and RFC 4034. +

+
+
+

OPTIONS

+
+
-a algorithm
+
+

+ Selects the cryptographic algorithm. The value of + algorithm must be one of RSAMD5 (RSA) + or RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA or DH (Diffie Hellman). + These values are case insensitive. +

+

+ Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement + algorithm, and DSA is recommended. +

+

+ Note 2: DH automatically sets the -k flag. +

+
+
-l label
+

+ Specifies the label of keys in the crypto hardware + (PKCS#11 device). +

+
-n nametype
+

+ Specifies the owner type of the key. The value of + nametype must either be ZONE (for a DNSSEC + zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with + a host (KEY)), + USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). + These values are + case insensitive. +

+
-c class
+

+ Indicates that the DNS record containing the key should have + the specified class. If not specified, class IN is used. +

+
-f flag
+

+ Set the specified flag in the flag field of the KEY/DNSKEY record. + The only recognized flag is KSK (Key Signing Key) DNSKEY. +

+
-h
+

+ Prints a short summary of the options and arguments to + dnssec-keygen. +

+
-k
+

+ Generate KEY records rather than DNSKEY records. +

+
-p protocol
+

+ Sets the protocol value for the generated key. The protocol + is a number between 0 and 255. The default is 3 (DNSSEC). + Other possible values for this argument are listed in + RFC 2535 and its successors. +

+
-t type
+

+ Indicates the use of the key. type must be + one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default + is AUTHCONF. AUTH refers to the ability to authenticate + data, and CONF the ability to encrypt data. +

+
-v level
+

+ Sets the debugging level. +

+
+
+
+

GENERATED KEY FILES

+

+ When dnssec-keyfromlabel completes + successfully, + it prints a string of the form Knnnn.+aaa+iiiii + to the standard output. This is an identification string for + the key files it has generated. +

+
    +

  • nnnn is the key name. +

    • +

  • aaa is the numeric representation + of the + algorithm. +

    • +

  • iiiii is the key identifier (or + footprint). +

    • +
+

dnssec-keyfromlabel + creates two files, with names based + on the printed string. Knnnn.+aaa+iiiii.key + contains the public key, and + Knnnn.+aaa+iiiii.private contains the + private + key. +

+

+ The .key file contains a DNS KEY record + that + can be inserted into a zone file (directly or with a $INCLUDE + statement). +

+

+ The .private file contains algorithm + specific + fields. For obvious security reasons, this file does not have + general read permission. +

+

DESCRIPTION

+

dnssec-keygen + generates keys for DNSSEC (Secure DNS), as defined in RFC 2535 + and RFC 4034. It can also generate keys for use with + TSIG (Transaction Signatures), as defined in RFC 2845. +

+
+
+

OPTIONS

+
+
-a algorithm
+
+

+ Selects the cryptographic algorithm. The value of + algorithm must be one of RSAMD5 (RSA) or RSASHA1, + DSA, NSEC3RSASHA1, NSEC3DSA, DH (Diffie Hellman), or HMAC-MD5. + These values are case insensitive. +

+

+ Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement + algorithm, and DSA is recommended. For TSIG, HMAC-MD5 is + mandatory. +

+

+ Note 2: HMAC-MD5 and DH automatically set the -k flag. +

+
+
-b keysize
+

+ Specifies the number of bits in the key. The choice of key + size depends on the algorithm used. RSAMD5 / RSASHA1 keys must be + between + 512 and 2048 bits. Diffie Hellman keys must be between + 128 and 4096 bits. DSA keys must be between 512 and 1024 + bits and an exact multiple of 64. HMAC-MD5 keys must be + between 1 and 512 bits. +

+
-n nametype
+

+ Specifies the owner type of the key. The value of + nametype must either be ZONE (for a DNSSEC + zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with + a host (KEY)), + USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). + These values are case insensitive. Defaults to ZONE for DNSKEY + generation. +

+
-c class
+

+ Indicates that the DNS record containing the key should have + the specified class. If not specified, class IN is used. +

+
-e
+

+ If generating an RSAMD5/RSASHA1 key, use a large exponent. +

+
-f flag
+

+ Set the specified flag in the flag field of the KEY/DNSKEY record. + The only recognized flag is KSK (Key Signing Key) DNSKEY. +

+
-g generator
+

+ If generating a Diffie Hellman key, use this generator. + Allowed values are 2 and 5. If no generator + is specified, a known prime from RFC 2539 will be used + if possible; otherwise the default is 2. +

+
-h
+

+ Prints a short summary of the options and arguments to + dnssec-keygen. +

+
-k
+

+ Generate KEY records rather than DNSKEY records. +

+
-p protocol
+

+ Sets the protocol value for the generated key. The protocol + is a number between 0 and 255. The default is 3 (DNSSEC). + Other possible values for this argument are listed in + RFC 2535 and its successors. +

+
-r randomdev
+

+ Specifies the source of randomness. If the operating + system does not provide a /dev/random + or equivalent device, the default source of randomness + is keyboard input. randomdev + specifies + the name of a character device or file containing random + data to be used instead of the default. The special value + keyboard indicates that keyboard + input should be used. +

+
-s strength
+

+ Specifies the strength value of the key. The strength is + a number between 0 and 15, and currently has no defined + purpose in DNSSEC. +

+
-t type
+

+ Indicates the use of the key. type must be + one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default + is AUTHCONF. AUTH refers to the ability to authenticate + data, and CONF the ability to encrypt data. +

+
-v level
+

+ Sets the debugging level. +

+
+
+
+

GENERATED KEYS

+

+ When dnssec-keygen completes + successfully, + it prints a string of the form Knnnn.+aaa+iiiii + to the standard output. This is an identification string for + the key it has generated. +

+
    +

  • nnnn is the key name. +

    • +

  • aaa is the numeric representation + of the + algorithm. +

    • +

  • iiiii is the key identifier (or + footprint). +

    • +
+

dnssec-keygen + creates two files, with names based + on the printed string. Knnnn.+aaa+iiiii.key + contains the public key, and + Knnnn.+aaa+iiiii.private contains the + private + key. +

+

+ The .key file contains a DNS KEY record + that + can be inserted into a zone file (directly or with a $INCLUDE + statement). +

+

+ The .private file contains + algorithm-specific + fields. For obvious security reasons, this file does not have + general read permission. +

+

+ Both .key and .private + files are generated for symmetric encryption algorithms such as + HMAC-MD5, even though the public and private key are equivalent. +

+
+
+

EXAMPLE

+

+ To generate a 768-bit DSA key for the domain + example.com, the following command would be + issued: +

+

dnssec-keygen -a DSA -b 768 -n ZONE example.com +

+

+ The command would print a string of the form: +

+

Kexample.com.+003+26160 +

+

+ In this example, dnssec-keygen creates + the files Kexample.com.+003+26160.key + and + Kexample.com.+003+26160.private. +

Existing DS records will be removed. +.RE +.PP +\-s \fIstart\-time\fR +.RS 4 +Specify the date and time when the generated RRSIG records become valid. This can be either an absolute or relative time. An absolute start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative start time is indicated by +N, which is N seconds from the current time. If no +\fBstart\-time\fR +is specified, the current time minus 1 hour (to allow for clock skew) is used. +.RE +.PP +\-e \fIend\-time\fR +.RS 4 +Specify the date and time when the generated RRSIG records expire. As with +\fBstart\-time\fR, an absolute time is indicated in YYYYMMDDHHMMSS notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A time relative to the current time is indicated with now+N. If no +\fBend\-time\fR +is specified, 30 days from the start time is used as a default. +.RE +.PP +\-f \fIoutput\-file\fR +.RS 4 +The name of the output file containing the signed zone. The default is to append +\fI.signed\fR +to the input filename. +.RE +.PP +\-h +.RS 4 +Prints a short summary of the options and arguments to +\fBdnssec\-signzone\fR. +.RE +.PP +\-i \fIinterval\fR +.RS 4 +When a previously\-signed zone is passed as input, records may be resigned. The +\fBinterval\fR +option specifies the cycle interval as an offset from the current time (in seconds). If a RRSIG record expires after the cycle interval, it is retained. Otherwise, it is considered to be expiring soon, and it will be replaced. +.sp +The default cycle interval is one quarter of the difference between the signature end and start times. So if neither +\fBend\-time\fR +or +\fBstart\-time\fR +are specified, +\fBdnssec\-signzone\fR +generates signatures that are valid for 30 days, with a cycle interval of 7.5 days. Therefore, if any existing RRSIG records are due to expire in less than 7.5 days, they would be replaced. +.RE +.PP +\-I \fIinput\-format\fR +.RS 4 +The format of the input zone file. Possible formats are +\fB"text"\fR +(default) and +\fB"raw"\fR. This option is primarily intended to be used for dynamic signed zones so that the dumped zone file in a non\-text format containing updates can be signed directly. The use of this option does not make much sense for non\-dynamic zones. +.RE +.PP +\-j \fIjitter\fR +.RS 4 +When signing a zone with a fixed signature lifetime, all RRSIG records issued at the time of signing expires simultaneously. If the zone is incrementally signed, i.e. a previously\-signed zone is passed as input to the signer, all expired signatures have to be regenerated at about the same time. The +\fBjitter\fR +option specifies a jitter window that will be used to randomize the signature expire time, thus spreading incremental signature regeneration over time. +.sp +Signature lifetime jitter also to some extent benefits validators and servers by spreading out cache expiration, i.e. if large numbers of RRSIGs don't expire at the same time from all caches there will be less congestion than if all validators need to refetch at mostly the same time. +.RE +.PP +\-n \fIncpus\fR +.RS 4 +Specifies the number of threads to use. By default, one thread is started for each detected CPU. +.RE +.PP +\-N \fIsoa\-serial\-format\fR +.RS 4 +The SOA serial number format of the signed zone.

If the operating system does not provide a +\fI/dev/random\fR +or equivalent device, the default source of randomness is keyboard input. +\fIrandomdev\fR +specifies the name of a character device or file containing random data to be used instead of the default.

DESCRIPTION

+

dnssec-signzone + signs a zone. It generates + NSEC and RRSIG records and produces a signed version of the + zone. The security status of delegations from the signed zone + (that is, whether the child zones are secure or not) is + determined by the presence or absence of a + keyset file for each child zone. +

+
+
+

OPTIONS

+
+
-a
+

+ Verify all generated signatures. +

+
-c class
+

+ Specifies the DNS class of the zone. +

+
-k key
+

+ Treat specified key as a key signing key ignoring any + key flags. This option may be specified multiple times. +

+
-l domain
+

+ Generate a DLV set in addition to the key (DNSKEY) and DS sets. + The domain is appended to the name of the records. +

+
-d directory
+

+ Look for keyset files in + directory as the directory +

+
-g
+

+ Generate DS records for child zones from keyset files. + Existing DS records will be removed. +

+
-s start-time
+

+ Specify the date and time when the generated RRSIG records + become valid. This can be either an absolute or relative + time. An absolute start time is indicated by a number + in YYYYMMDDHHMMSS notation; 20000530144500 denotes + 14:45:00 UTC on May 30th, 2000. A relative start time is + indicated by +N, which is N seconds from the current time. + If no start-time is specified, the current + time minus 1 hour (to allow for clock skew) is used. +

+
-e end-time
+

+ Specify the date and time when the generated RRSIG records + expire. As with start-time, an absolute + time is indicated in YYYYMMDDHHMMSS notation. A time relative + to the start time is indicated with +N, which is N seconds from + the start time. A time relative to the current time is + indicated with now+N. If no end-time is + specified, 30 days from the start time is used as a default. +

+
-f output-file
+

+ The name of the output file containing the signed zone. The + default is to append .signed to + the + input filename. +

+
-h
+

+ Prints a short summary of the options and arguments to + dnssec-signzone. +

+
-i interval
+
+

+ When a previously-signed zone is passed as input, records + may be resigned. The interval option + specifies the cycle interval as an offset from the current + time (in seconds). If a RRSIG record expires after the + cycle interval, it is retained. Otherwise, it is considered + to be expiring soon, and it will be replaced. +

+

+ The default cycle interval is one quarter of the difference + between the signature end and start times. So if neither + end-time or start-time + are specified, dnssec-signzone + generates + signatures that are valid for 30 days, with a cycle + interval of 7.5 days. Therefore, if any existing RRSIG records + are due to expire in less than 7.5 days, they would be + replaced. +

+
+
-I input-format
+

+ The format of the input zone file. + Possible formats are "text" (default) + and "raw". + This option is primarily intended to be used for dynamic + signed zones so that the dumped zone file in a non-text + format containing updates can be signed directly. + The use of this option does not make much sense for + non-dynamic zones. +

+
-j jitter
+
+

+ When signing a zone with a fixed signature lifetime, all + RRSIG records issued at the time of signing expires + simultaneously. If the zone is incrementally signed, i.e. + a previously-signed zone is passed as input to the signer, + all expired signatures have to be regenerated at about the + same time. The jitter option specifies a + jitter window that will be used to randomize the signature + expire time, thus spreading incremental signature + regeneration over time. +

+

+ Signature lifetime jitter also to some extent benefits + validators and servers by spreading out cache expiration, + i.e. if large numbers of RRSIGs don't expire at the same time + from all caches there will be less congestion than if all + validators need to refetch at mostly the same time. +

+
+
-n ncpus
+

+ Specifies the number of threads to use. By default, one + thread is started for each detected CPU. +

+
-N soa-serial-format
+
+

+ The SOA serial number format of the signed zone. + Possible formats are "keep" (default), + "increment" and + "unixtime". +

+
+
"keep"
+

Do not modify the SOA serial number.

+
"increment"
+

Increment the SOA serial number using RFC 1982 + arithmetics.

+
"unixtime"
+

Set the SOA serial number to the number of seconds + since epoch.

+
+
+
-o origin
+

+ The zone origin. If not specified, the name of the zone file + is assumed to be the origin. +

+
-O output-format
+

+ The format of the output file containing the signed zone. + Possible formats are "text" (default) + and "raw". +

+
-p
+

+ Use pseudo-random data when signing the zone. This is faster, + but less secure, than using real random data. This option + may be useful when signing large zones or when the entropy + source is limited. +

+
-r randomdev
+

+ Specifies the source of randomness. If the operating + system does not provide a /dev/random + or equivalent device, the default source of randomness + is keyboard input. randomdev + specifies + the name of a character device or file containing random + data to be used instead of the default. The special value + keyboard indicates that keyboard + input should be used. +

+
-t
+

+ Print statistics at completion. +

+
-v level
+

+ Sets the debugging level. +

+
-z
+

+ Ignore KSK flag on key when determining what to sign. +

+
-3 salt
+

+ Generate a NSEC3 chain with the given hex encoded salt. + A dash (salt) can + be used to indicate that no salt is to be used when generating the NSEC3 chain. +

+
-H iterations
+

+ When generating a NSEC3 chain use this many interations. The + default is 100. +

+
-A
+

+ When generating a NSEC3 chain set the OPTOUT flag on all + NSEC3 records and do not generate NSEC3 records for insecure + delegations. +

+
zonefile
+

+ The file containing the zone to be signed. +

+
key
+

+ Specify which keys should be used to sign the zone. If + no keys are specified, then the zone will be examined + for DNSKEY records at the zone apex. If these are found and + there are matching private keys, in the current directory, + then these will be used for signing. +

+
+
+
+

EXAMPLE

+

+ The following command signs the example.com + zone with the DSA key generated by dnssec-keygen + (Kexample.com.+003+17247). The zone's keys must be in the master + file (db.example.com). This invocation looks + for keyset files, in the current directory, + so that DS records can be generated from them (-g). +

+
% dnssec-signzone -g -o example.com db.example.com \
+Kexample.com.+003+17247
+db.example.com.signed
+%
+

+ In the above example, dnssec-signzone creates + the file db.example.com.signed. This + file should be referenced in a zone statement in a + named.conf file. +

+

+ This example re-signs a previously signed zone with default parameters. + The private keys are assumed to be in the current directory. +

+
% cp db.example.com.signed db.example.com
+% dnssec-signzone -o example.com db.example.com
+db.example.com.signed
+%

It is essentially a stripped\-down, caching\-only name server that answers queries using the BIND 9 lightweight resolver protocol rather than the DNS protocol. +.PP +\fBlwresd\fR +listens for resolver queries on a UDP port on the IPv4 loopback interface, 127.0.0.1. This means that +\fBlwresd\fR +can only be used by processes running on the local machine. By default UDP port number 921 is used for lightweight resolver requests and responses. +.PP +Incoming lightweight resolver requests are decoded by the server which then resolves them using the DNS protocol. When the DNS lookup completes, +\fBlwresd\fR +encodes the answers in the lightweight resolver format and returns them to the client that made the request. +.PP +If +\fI/etc/resolv.conf\fR +contains any +\fBnameserver\fR +entries, +\fBlwresd\fR +sends recursive DNS queries to those servers. This is similar to the use of forwarders in a caching name server. If no +\fBnameserver\fR +entries are present, or if forwarding fails, +\fBlwresd\fR +resolves the queries autonomously starting at the root name servers, using a built\-in list of root server hints. +.SH "OPTIONS" +.PP +\-4 +.RS 4 +Use IPv4 only even if the host machine is capable of IPv6. +\fB\-4\fR +and +\fB\-6\fR +are mutually exclusive. +.RE +.PP +\-6 +.RS 4 +Use IPv6 only even if the host machine is capable of IPv4. +\fB\-4\fR +and +\fB\-6\fR +are mutually exclusive. +.RE +.PP +\-c \fIconfig\-file\fR +.RS 4 +Use +\fIconfig\-file\fR +as the configuration file instead of the default, +\fI/etc/lwresd.conf\fR. +\fB\-c\fR +can not be used with +\fB\-C\fR. +.RE +.PP +\-C \fIconfig\-file\fR +.RS 4 +Use +\fIconfig\-file\fR +as the configuration file instead of the default, +\fI/etc/resolv.conf\fR. +\fB\-C\fR +can not be used with +\fB\-c\fR. +.RE +.PP +\-d \fIdebug\-level\fR +.RS 4 +Set the daemon's debug level to +\fIdebug\-level\fR.

Name

+

lwresd — lightweight resolver daemon

+
+
+

Synopsis

+

lwresd [-c config-file] [-C config-file] [-d debug-level] [-f] [-g] [-i pid-file] [-m flag] [-n #cpus] [-P port] [-p port] [-s] [-t directory] [-u user] [-v] [-4] [-6]

+
+

DESCRIPTION

+

lwresd + is the daemon providing name lookup + services to clients that use the BIND 9 lightweight resolver + library. It is essentially a stripped-down, caching-only name + server that answers queries using the BIND 9 lightweight + resolver protocol rather than the DNS protocol. +

+

lwresd + listens for resolver queries on a + UDP port on the IPv4 loopback interface, 127.0.0.1. This + means that lwresd can only be used by + processes running on the local machine. By default UDP port + number 921 is used for lightweight resolver requests and + responses. +

+

+ Incoming lightweight resolver requests are decoded by the + server which then resolves them using the DNS protocol. When + the DNS lookup completes, lwresd encodes + the answers in the lightweight resolver format and returns + them to the client that made the request. +

+

+ If /etc/resolv.conf contains any + nameserver entries, lwresd + sends recursive DNS queries to those servers. This is similar + to the use of forwarders in a caching name server. If no + nameserver entries are present, or if + forwarding fails, lwresd resolves the + queries autonomously starting at the root name servers, using + a built-in list of root server hints. +

+
+
+

OPTIONS

+
+
-4
+

+ Use IPv4 only even if the host machine is capable of IPv6. + -4 and -6 are mutually + exclusive. +

+
-6
+

+ Use IPv6 only even if the host machine is capable of IPv4. + -4 and -6 are mutually + exclusive. +

+
-c config-file
+

+ Use config-file as the + configuration file instead of the default, + /etc/lwresd.conf. + + -c can not be used with -C. +

+
-C config-file
+

+ Use config-file as the + configuration file instead of the default, + /etc/resolv.conf. + -C can not be used with -c. +

+
-d debug-level
+

+ Set the daemon's debug level to debug-level. + Debugging traces from lwresd become + more verbose as the debug level increases. +

+
-f
+

+ Run the server in the foreground (i.e. do not daemonize). +

+
-g
+

+ Run the server in the foreground and force all logging + to stderr. +

+
-i pid-file
+

+ Use pid-file as the + PID file instead of the default, + /var/run/lwresd/lwresd.pid. +

+
-m flag
+

+ Turn on memory usage debugging flags. Possible flags are + usage, + trace, + record, + size, and + mctx. + These correspond to the ISC_MEM_DEBUGXXXX flags described in + <isc/mem.h>. +

+
-n #cpus
+

+ Create #cpus worker threads + to take advantage of multiple CPUs. If not specified, + lwresd will try to determine the + number of CPUs present and create one thread per CPU. + If it is unable to determine the number of CPUs, a + single worker thread will be created. +

+
-P port
+

+ Listen for lightweight resolver queries on port + port. If + not specified, the default is port 921. +

+
-p port
+

+ Send DNS lookups to port port. If not + specified, the default is port 53. This provides a + way of testing the lightweight resolver daemon with a + name server that listens for queries on a non-standard + port number. +

+
-s
+
+

+ Write memory usage statistics to stdout + on exit. +

+
+

Note

+

+ This option is mainly of interest to BIND 9 developers + and may be removed or changed in a future release. +

+
+
+
-t directory
+
+

Chroot + to directory after + processing the command line arguments, but before + reading the configuration file. +

+
+

Warning

+

+ This option should be used in conjunction with the + -u option, as chrooting a process + running as root doesn't enhance security on most + systems; the way chroot(2) is + defined allows a process with root privileges to + escape a chroot jail. +

+
+
+
-u user
+

Setuid + to user after completing + privileged operations, such as creating sockets that + listen on privileged ports. +

+
-v
+

+ Report the version number and exit. +

+
+
+
+

FILES

+
+
/etc/resolv.conf
+

+ The default configuration file. +

+
/var/run/lwresd.pid
+

+ The default process-id file. +

+
+
+

Name

+

named — Internet domain name server

+
+
+

Synopsis

+

named [-4] [-6] [-c config-file] [-d debug-level] [-f] [-g] [-m flag] [-n #cpus] [-p port] [-s] [-S #max-socks] [-t directory] [-u user] [-v] [-V] [-x cache-file]

+
+
+

DESCRIPTION

+

named + is a Domain Name System (DNS) server, + part of the BIND 9 distribution from ISC. For more + information on the DNS, see RFCs 1033, 1034, and 1035. +

+

+ When invoked without arguments, named + will + read the default configuration file + /etc/named.conf, read any initial + data, and listen for queries. +

+
+
+

OPTIONS

+
+
-4
+

+ Use IPv4 only even if the host machine is capable of IPv6. + -4 and -6 are mutually + exclusive. +

+
-6
+

+ Use IPv6 only even if the host machine is capable of IPv4. + -4 and -6 are mutually + exclusive. +

+
-c config-file
+

+ Use config-file as the + configuration file instead of the default, + /etc/named.conf. To + ensure that reloading the configuration file continues + to work after the server has changed its working + directory due to to a possible + directory option in the configuration + file, config-file should be + an absolute pathname. +

+
-d debug-level
+

+ Set the daemon's debug level to debug-level. + Debugging traces from named become + more verbose as the debug level increases. +

+
-f
+

+ Run the server in the foreground (i.e. do not daemonize). +

+
-g
+

+ Run the server in the foreground and force all logging + to stderr. +

+
-m flag
+

+ Turn on memory usage debugging flags. Possible flags are + usage, + trace, + record, + size, and + mctx. + These correspond to the ISC_MEM_DEBUGXXXX flags described in + <isc/mem.h>. +

+
-n #cpus
+

+ Create #cpus worker threads + to take advantage of multiple CPUs. If not specified, + named will try to determine the + number of CPUs present and create one thread per CPU. + If it is unable to determine the number of CPUs, a + single worker thread will be created. +

+
-p port
+

+ Listen for queries on port port. If not + specified, the default is port 53. +

+
-s
+
+

+ Write memory usage statistics to stdout on exit. +

+
+

Note

+

+ This option is mainly of interest to BIND 9 developers + and may be removed or changed in a future release. +

+
+
+
-S #max-socks
+
+

+ Allow named to use up to + #max-socks sockets. +

+
+

Warning

+

+ This option should be unnecessary for the vast majority + of users. + The use of this option could even be harmful because the + specified value may exceed the limitation of the + underlying system API. + It is therefore set only when the default configuration + causes exhaustion of file descriptors and the + operational environment is known to support the + specified number of sockets. + Note also that the actual maximum number is normally a little + fewer than the specified value because + named reserves some file descriptors + for its internal use. +

+
+
+
-t directory
+
+

Chroot + to directory after + processing the command line arguments, but before + reading the configuration file. +

+
+

Warning

+

+ This option should be used in conjunction with the + -u option, as chrooting a process + running as root doesn't enhance security on most + systems; the way chroot(2) is + defined allows a process with root privileges to + escape a chroot jail. +

+
+
+
-u user
+
+

Setuid + to user after completing + privileged operations, such as creating sockets that + listen on privileged ports. +

+
+

Note

+

+ On Linux, named uses the kernel's + capability mechanism to drop all root privileges + except the ability to bind(2) to + a + privileged port and set process resource limits. + Unfortunately, this means that the -u + option only works when named is + run + on kernel 2.2.18 or later, or kernel 2.3.99-pre3 or + later, since previous kernels did not allow privileges + to be retained after setuid(2). +

+
+
+
-v
+

+ Report the version number and exit. +

+
-V
+

+ Report the version number and build options, and exit. +

+
-x cache-file
+
+

+ Load data from cache-file into the + cache of the default view. +

+
+

Warning

+

+ This option must not be used. It is only of interest + to BIND 9 developers and may be removed or changed in a + future release. +

+
+
+
+
+
+

SIGNALS

+

+ In routine operation, signals should not be used to control + the nameserver; rndc should be used + instead. +

+
+
SIGHUP
+

+ Force a reload of the server. +

+
SIGINT, SIGTERM
+

+ Shut down the server. +

+
+

+ The result of sending any other signals to the server is undefined. +

+
+
+

CONFIGURATION

+

+ The named configuration file is too complex + to describe in detail here. A complete description is provided + in the + BIND 9 Administrator Reference Manual. +

+
+
+

FILES

+
+
/etc/named.conf
+

+ The default configuration file. +

+
/var/run/named/named.pid
+

+ The default process-id file. +

+
+
+
+

This allows resource records to be added or removed from a zone without manually editing the zone file. A single update request can contain requests to add or remove more than one resource record. +.PP +Zones that are under dynamic control via +\fBnsupdate\fR +or a DHCP server should not be edited by hand. Manual edits could conflict with dynamic updates and cause data to be lost. +.PP +The resource records that are dynamically added or removed with +\fBnsupdate\fR +have to be in the same zone. Requests are sent to the zone's master server. This is identified by the MNAME field of the zone's SOA record. +.PP +The +\fB\-d\fR +option makes +\fBnsupdate\fR +operate in debug mode. This provides tracing information about the update requests that are made and the replies received from the name server. +.PP +The +\fB\-D\fR +option makes +\fBnsupdate\fR +report additional debugging information to +\fB\-d\fR. +.PP +Transaction signatures can be used to authenticate the Dynamic DNS updates. These use the TSIG resource record type described in RFC2845 or the SIG(0) record described in RFC3535 and RFC2931. TSIG relies on a shared secret that should only be known to +\fBnsupdate\fR +and the name server. Currently, the only supported encryption algorithm for TSIG is HMAC\-MD5, which is defined in RFC 2104. Once other algorithms are defined for TSIG, applications will need to ensure they select the appropriate algorithm as well as the key when authenticating each other. For instance, suitable +\fBkey\fR +and +\fBserver\fR +statements would be added to +\fI/etc/named.conf\fR +so that the name server can associate the appropriate secret key and algorithm with the IP address of the client application that will be using TSIG authentication. SIG(0) uses public key cryptography. To use a SIG(0) key, the public key must be stored in a KEY record in a zone served by the name server. +\fBnsupdate\fR +does not read +\fI/etc/named.conf\fR. +.PP +\fBnsupdate\fR +uses the +\fB\-y\fR +or +\fB\-k\fR +option to provide the shared secret needed to generate a TSIG record for authenticating Dynamic DNS update requests, default type HMAC\-MD5. These options are mutually exclusive. With the +\fB\-k\fR +option, +\fBnsupdate\fR +reads the shared secret from the file +\fIkeyfile\fR, whose name is of the form +\fIK{name}.+157.+{random}.private\fR. For historical reasons, the file +\fIK{name}.+157.+{random}.key\fR +must also be present. When the +\fB\-y\fR +option is used, a signature is generated from +[\fIhmac:\fR]\fIkeyname:secret.\fR +\fIkeyname\fR +is the name of the key, and +\fIsecret\fR +is the base64 encoded shared secret. Use of the +\fB\-y\fR +option is discouraged because the shared secret is supplied as a command line argument in clear text. This may be visible in the output from +\fBps\fR(1) +or in a history file maintained by the user's shell. +.PP +The +\fB\-k\fR +may also be used to specify a SIG(0) key used to authenticate Dynamic DNS update requests. In this case, the key specified is not an HMAC\-MD5 key. +.PP +By default +\fBnsupdate\fR +uses UDP to send update requests to the name server unless they are too large to fit in a UDP request in which case TCP will be used. The +\fB\-v\fR +option makes +\fBnsupdate\fR +use a TCP connection. This may be preferable when a batch of update requests is made. +.PP +The +\fB\-t\fR +option sets the maximum time an update request can take before it is aborted. The default is 300 seconds. Zero can be used to disable the timeout. +.PP +The +\fB\-u\fR +option sets the UDP retry interval. The default is 3 seconds. If zero, the interval will be computed from the timeout interval and number of UDP retries. +.PP +The +\fB\-r\fR +option sets the number of UDP retries. The default is 3. If zero, only one update request will be made. +.PP +The +\fB\-R \fR\fB\fIrandomdev\fR\fR +option specifies a source of randomness. If the operating system does not provide a +\fI/dev/random\fR +or equivalent device, the default source of randomness is keyboard input. +\fIrandomdev\fR +specifies the name of a character device or file containing random data to be used instead of the default. The special value +\fIkeyboard\fR +indicates that keyboard input should be used. This option may be specified multiple times. +.SH "INPUT FORMAT" +.PP +\fBnsupdate\fR +reads input from +\fIfilename\fR +or standard input. Each command is supplied on exactly one line of input. Some commands are for administrative purposes. The others are either update instructions or prerequisite checks on the contents of the zone. These checks set conditions that some name or set of resource records (RRset) either exists or is absent from the zone. These conditions must be met if the entire update request is to succeed. Updates will be rejected if the tests for the prerequisite conditions fail. +.PP +Every update request consists of zero or more prerequisites and zero or more updates. This allows a suitably authenticated update request to proceed if some specified resource records are present or missing from the zone. A blank input line (or the +\fBsend\fR +command) causes the accumulated commands to be sent as one Dynamic DNS update request to the name server. +.PP +The command formats and their meaning are as follows: +.PP +\fBserver\fR {servername} [port] +.RS 4 +Sends all dynamic update requests to the name server +\fIservername\fR. When no server statement is provided, +\fBnsupdate\fR +will send updates to the master server of the correct zone. The MNAME field of that zone's SOA record will identify the master server for that zone. +\fIport\fR +is the port number on +\fIservername\fR +where the dynamic update requests get sent. If no port number is specified, the default DNS port number of 53 is used. +.RE +.PP +\fBlocal\fR {address} [port] +.RS 4 +Sends all dynamic update requests using the local +\fIaddress\fR. When no local statement is provided, +\fBnsupdate\fR +will send updates using an address and port chosen by the system. +\fIport\fR +can additionally be used to make requests come from a specific port. If no port number is specified, the system will assign one. +.RE +.PP +\fBzone\fR {zonename} +.RS 4 +Specifies that all updates are to be made to the zone +\fIzonename\fR. If no +\fIzone\fR +statement is provided, +\fBnsupdate\fR +will attempt determine the correct zone to update based on the rest of the input. +.RE +.PP +\fBclass\fR {classname} +.RS 4 +Specify the default class. If no +\fIclass\fR +is specified, the default class is +\fIIN\fR. +.RE +.PP +\fBttl\fR {seconds} +.RS 4 +Specify the default time to live for records to be added. The value +\fInone\fR +will clear the default ttl. +.RE +.PP +\fBkey\fR {name} {secret} +.RS 4 +Specifies that all updates are to be TSIG\-signed using the +\fIkeyname\fR +\fIkeysecret\fR +pair. The +\fBkey\fR +command overrides any key specified on the command line via +\fB\-y\fR +or +\fB\-k\fR. +.RE +.PP +\fBprereq nxdomain\fR {domain\-name} +.RS 4 +Requires that no resource record of any type exists with name +\fIdomain\-name\fR. +.RE +.PP +\fBprereq yxdomain\fR {domain\-name} +.RS 4 +Requires that +\fIdomain\-name\fR +exists (has as at least one resource record, of any type). +.RE +.PP +\fBprereq nxrrset\fR {domain\-name} [class] {type} +.RS 4 +Requires that no resource record exists of the specified +\fItype\fR, +\fIclass\fR +and +\fIdomain\-name\fR. If +\fIclass\fR +is omitted, IN (internet) is assumed. +.RE +.PP +\fBprereq yxrrset\fR {domain\-name} [class] {type} +.RS 4 +This requires that a resource record of the specified +\fItype\fR, +\fIclass\fR +and +\fIdomain\-name\fR +must exist. If +\fIclass\fR +is omitted, IN (internet) is assumed. +.RE +.PP +\fBprereq yxrrset\fR {domain\-name} [class] {type} {data...} +.RS 4 +The +\fIdata\fR +from each set of prerequisites of this form sharing a common +\fItype\fR, +\fIclass\fR, and +\fIdomain\-name\fR +are combined to form a set of RRs. This set of RRs must exactly match the set of RRs existing in the zone at the given +\fItype\fR, +\fIclass\fR, and +\fIdomain\-name\fR. The +\fIdata\fR +are written in the standard text representation of the resource record's RDATA. +.RE +.PP +\fBupdate delete\fR {domain\-name} [ttl] [class] [type\ [data...]] +.RS 4 +Deletes any resource records named +\fIdomain\-name\fR. If +\fItype\fR +and +\fIdata\fR +is provided, only matching resource records will be removed. The internet class is assumed if +\fIclass\fR +is not supplied. The +\fIttl\fR +is ignored, and is only allowed for compatibility. +.RE +.PP +\fBupdate add\fR {domain\-name} {ttl} [class] {type} {data...} +.RS 4 +Adds a new resource record with the specified +\fIttl\fR, +\fIclass\fR +and +\fIdata\fR. +.RE +.PP +\fBshow\fR +.RS 4 +Displays the current message, containing all of the prerequisites and updates specified since the last send. +.RE +.PP +\fBsend\fR +.RS 4 +Sends the current message. This is equivalent to entering a blank line. +.RE +.PP +\fBanswer\fR +.RS 4 +Displays the answer. +.RE +.PP +\fBdebug\fR +.RS 4 +Turn on debugging. +.RE +.PP +Lines beginning with a semicolon are comments and are ignored. +.SH "EXAMPLES" +.PP +The examples below show how +\fBnsupdate\fR +could be used to insert and delete resource records from the +\fBexample.com\fR +zone. Notice that the input in each example contains a trailing blank line so that a group of commands are sent as one dynamic update request to the master name server for +\fBexample.com\fR. +.sp +.RS 4 +.nf +# nsupdate +> update delete oldhost.example.com A +> update add newhost.example.com 86400 A 172.16.1.1 +> send +.fi +.RE +.sp +.PP +Any A records for +\fBoldhost.example.com\fR +are deleted. And an A record for +\fBnewhost.example.com\fR +with IP address 172.16.1.1 is added.

If there are, the update request fails. If this name does not exist, a CNAME for it is added. This ensures that when the CNAME is added, it cannot conflict with the long\-standing rule in RFC1034 that a name must not exist as any other record type if it exists as a CNAME. (The rule has been updated for DNSSEC in RFC2535 to allow CNAMEs to have RRSIG, DNSKEY and NSEC records.) +.SH "FILES" +.PP +\fB/etc/resolv.conf\fR +.RS 4 +used to identify default name server +.RE +.PP +\fBK{name}.+157.+{random}.key\fR +.RS 4 +base\-64 encoding of HMAC\-MD5 key created by +\fBdnssec\-keygen\fR(8). +.RE +.PP +\fBK{name}.+157.+{random}.private\fR +.RS 4 +base\-64 encoding of HMAC\-MD5 key created by +\fBdnssec\-keygen\fR(8). +.RE +.SH "SEE ALSO" +.PP +\fBRFC2136\fR(), +\fBRFC3007\fR(), +\fBRFC2104\fR(), +\fBRFC2845\fR(), +\fBRFC1034\fR(), +\fBRFC2535\fR(), +\fBRFC2931\fR(), +\fBnamed\fR(8), +\fBdnssec\-keygen\fR(8). +.SH "BUGS" +.PP +The TSIG key is redundantly stored in two separate files.

Synopsis

+

nsupdate [-d] [-D] [[-y [hmac:]keyname:secret] | [-k keyfile]] [-t timeout] [-u udptimeout] [-r udpretries] [-R randomdev] [-v] [filename]

+
+
+

DESCRIPTION

+

nsupdate + is used to submit Dynamic DNS Update requests as defined in RFC2136 + to a name server. + This allows resource records to be added or removed from a zone + without manually editing the zone file. + A single update request can contain requests to add or remove more than + one + resource record. +

+

+ Zones that are under dynamic control via + nsupdate + or a DHCP server should not be edited by hand. + Manual edits could + conflict with dynamic updates and cause data to be lost. +

+

+ The resource records that are dynamically added or removed with + nsupdate + have to be in the same zone. + Requests are sent to the zone's master server. + This is identified by the MNAME field of the zone's SOA record. +

+

+ The + -d + option makes + nsupdate + operate in debug mode. + This provides tracing information about the update requests that are + made and the replies received from the name server. +

+

+ The -D option makes nsupdate + report additional debugging information to -d. +

+

+ Transaction signatures can be used to authenticate the Dynamic DNS + updates. + These use the TSIG resource record type described in RFC2845 or the + SIG(0) record described in RFC3535 and RFC2931. + TSIG relies on a shared secret that should only be known to + nsupdate and the name server. + Currently, the only supported encryption algorithm for TSIG is + HMAC-MD5, which is defined in RFC 2104. + Once other algorithms are defined for TSIG, applications will need to + ensure they select the appropriate algorithm as well as the key when + authenticating each other. + For instance, suitable + key + and + server + statements would be added to + /etc/named.conf + so that the name server can associate the appropriate secret key + and algorithm with the IP address of the + client application that will be using TSIG authentication. + SIG(0) uses public key cryptography. To use a SIG(0) key, the public + key must be stored in a KEY record in a zone served by the name server. + nsupdate + does not read + /etc/named.conf. +

+

nsupdate + uses the -y or -k option + to provide the shared secret needed to generate a TSIG record + for authenticating Dynamic DNS update requests, default type + HMAC-MD5. These options are mutually exclusive. With the + -k option, nsupdate reads + the shared secret from the file keyfile, + whose name is of the form + K{name}.+157.+{random}.private. For + historical reasons, the file + K{name}.+157.+{random}.key must also be + present. When the -y option is used, a + signature is generated from + [hmac:]keyname:secret. + keyname is the name of the key, and + secret is the base64 encoded shared + secret. Use of the -y option is discouraged + because the shared secret is supplied as a command line + argument in clear text. This may be visible in the output + from + ps(1) or in a history file maintained by the user's + shell. +

+

+ The -k may also be used to specify a SIG(0) key used + to authenticate Dynamic DNS update requests. In this case, the key + specified is not an HMAC-MD5 key. +

+

+ By default + nsupdate + uses UDP to send update requests to the name server unless they are too + large to fit in a UDP request in which case TCP will be used. + The + -v + option makes + nsupdate + use a TCP connection. + This may be preferable when a batch of update requests is made. +

+

+ The -t option sets the maximum time an update request + can + take before it is aborted. The default is 300 seconds. Zero can be + used + to disable the timeout. +

+

+ The -u option sets the UDP retry interval. The default + is + 3 seconds. If zero, the interval will be computed from the timeout + interval + and number of UDP retries. +

+

+ The -r option sets the number of UDP retries. The + default is + 3. If zero, only one update request will be made. +

+

+ The -R randomdev option + specifies a source of randomness. If the operating system + does not provide a /dev/random or + equivalent device, the default source of randomness is keyboard + input. randomdev specifies the name of + a character device or file containing random data to be used + instead of the default. The special value + keyboard indicates that keyboard input + should be used. This option may be specified multiple times. +

+
+
+

INPUT FORMAT

+

nsupdate + reads input from + filename + or standard input. + Each command is supplied on exactly one line of input. + Some commands are for administrative purposes. + The others are either update instructions or prerequisite checks on the + contents of the zone. + These checks set conditions that some name or set of + resource records (RRset) either exists or is absent from the zone. + These conditions must be met if the entire update request is to succeed. + Updates will be rejected if the tests for the prerequisite conditions + fail. +

+

+ Every update request consists of zero or more prerequisites + and zero or more updates. + This allows a suitably authenticated update request to proceed if some + specified resource records are present or missing from the zone. + A blank input line (or the send command) + causes the + accumulated commands to be sent as one Dynamic DNS update request to the + name server. +

+

+ The command formats and their meaning are as follows: +

+
+
+ server + {servername} + [port] +
+

+ Sends all dynamic update requests to the name server + servername. + When no server statement is provided, + nsupdate + will send updates to the master server of the correct zone. + The MNAME field of that zone's SOA record will identify the + master + server for that zone. + port + is the port number on + servername + where the dynamic update requests get sent. + If no port number is specified, the default DNS port number of + 53 is + used. +

+
+ local + {address} + [port] +
+

+ Sends all dynamic update requests using the local + address. + + When no local statement is provided, + nsupdate + will send updates using an address and port chosen by the + system. + port + can additionally be used to make requests come from a specific + port. + If no port number is specified, the system will assign one. +

+
+ zone + {zonename} +
+

+ Specifies that all updates are to be made to the zone + zonename. + If no + zone + statement is provided, + nsupdate + will attempt determine the correct zone to update based on the + rest of the input. +

+
+ class + {classname} +
+

+ Specify the default class. + If no class is specified, the + default class is + IN. +

+
+ ttl + {seconds} +
+

+ Specify the default time to live for records to be added. + The value none will clear the default + ttl. +

+
+ key + {name} + {secret} +
+

+ Specifies that all updates are to be TSIG-signed using the + keyname keysecret pair. + The key command + overrides any key specified on the command line via + -y or -k. +

+
+ prereq nxdomain + {domain-name} +
+

+ Requires that no resource record of any type exists with name + domain-name. +

+
+ prereq yxdomain + {domain-name} +
+

+ Requires that + domain-name + exists (has as at least one resource record, of any type). +

+
+ prereq nxrrset + {domain-name} + [class] + {type} +
+

+ Requires that no resource record exists of the specified + type, + class + and + domain-name. + If + class + is omitted, IN (internet) is assumed. +

+
+ prereq yxrrset + {domain-name} + [class] + {type} +
+

+ This requires that a resource record of the specified + type, + class + and + domain-name + must exist. + If + class + is omitted, IN (internet) is assumed. +

+
+ prereq yxrrset + {domain-name} + [class] + {type} + {data...} +
+

+ The + data + from each set of prerequisites of this form + sharing a common + type, + class, + and + domain-name + are combined to form a set of RRs. This set of RRs must + exactly match the set of RRs existing in the zone at the + given + type, + class, + and + domain-name. + The + data + are written in the standard text representation of the resource + record's + RDATA. +

+
+ update delete + {domain-name} + [ttl] + [class] + [type [data...]] +
+

+ Deletes any resource records named + domain-name. + If + type + and + data + is provided, only matching resource records will be removed. + The internet class is assumed if + class + is not supplied. The + ttl + is ignored, and is only allowed for compatibility. +

+
+ update add + {domain-name} + {ttl} + [class] + {type} + {data...} +
+

+ Adds a new resource record with the specified + ttl, + class + and + data. +

+
+ show +
+

+ Displays the current message, containing all of the + prerequisites and + updates specified since the last send. +

+
+ send +
+

+ Sends the current message. This is equivalent to entering a + blank line. +

+
+ answer +
+

+ Displays the answer. +

+
+ debug +
+

+ Turn on debugging. +

+
+

+

+

+ Lines beginning with a semicolon are comments and are ignored. +

+
+
+

EXAMPLES

+

+ The examples below show how + nsupdate + could be used to insert and delete resource records from the + example.com + zone. + Notice that the input in each example contains a trailing blank line so + that + a group of commands are sent as one dynamic update request to the + master name server for + example.com. + +

+
+# nsupdate
+> update delete oldhost.example.com A
+> update add newhost.example.com 86400 A 172.16.1.1
+> send
+
+

+

+

+ Any A records for + oldhost.example.com + are deleted. + And an A record for + newhost.example.com + with IP address 172.16.1.1 is added. + The newly-added record has a 1 day TTL (86400 seconds). +

+
+# nsupdate
+> prereq nxdomain nickname.example.com
+> update add nickname.example.com 86400 CNAME somehost.example.com
+> send
+
+

+ The prerequisite condition gets the name server to check that there + are no resource records of any type for + nickname.example.com. + + If there are, the update request fails. + If this name does not exist, a CNAME for it is added. + This ensures that when the CNAME is added, it cannot conflict with the + long-standing rule in RFC1034 that a name must not exist as any other + record type if it exists as a CNAME. + (The rule has been updated for DNSSEC in RFC2535 to allow CNAMEs to have + RRSIG, DNSKEY and NSEC records.) +

BUGS

+

+ The TSIG key is redundantly stored in two separate files. + This is a consequence of nsupdate using the DST library + for its cryptographic operations, and may change in future + releases. +

Name

+

rndc-confgen — rndc key generation tool

+
+
+

Synopsis

+

rndc-confgen [-a] [-b keysize] [-c keyfile] [-h] [-k keyname] [-p port] [-r randomfile] [-s address] [-t chrootdir] [-u user]

+
+
+

DESCRIPTION

+

rndc-confgen + generates configuration files + for rndc. It can be used as a + convenient alternative to writing the + rndc.conf file + and the corresponding controls + and key + statements in named.conf by hand. + Alternatively, it can be run with the -a + option to set up a rndc.key file and + avoid the need for a rndc.conf file + and a controls statement altogether. +

+
+
+

OPTIONS

+
+
-a
+
+

+ Do automatic rndc configuration. + This creates a file rndc.key + in /etc (or whatever + sysconfdir + was specified as when BIND was + built) + that is read by both rndc + and named on startup. The + rndc.key file defines a default + command channel and authentication key allowing + rndc to communicate with + named on the local host + with no further configuration. +

+

+ Running rndc-confgen -a allows + BIND 9 and rndc to be used as + drop-in + replacements for BIND 8 and ndc, + with no changes to the existing BIND 8 + named.conf file. +

+

+ If a more elaborate configuration than that + generated by rndc-confgen -a + is required, for example if rndc is to be used remotely, + you should run rndc-confgen without + the + -a option and set up a + rndc.conf and + named.conf + as directed. +

+
+
-b keysize
+

+ Specifies the size of the authentication key in bits. + Must be between 1 and 512 bits; the default is 128. +

+
-c keyfile
+

+ Used with the -a option to specify + an alternate location for rndc.key. +

+
-h
+

+ Prints a short summary of the options and arguments to + rndc-confgen. +

+
-k keyname
+

+ Specifies the key name of the rndc authentication key. + This must be a valid domain name. + The default is rndc-key. +

+
-p port
+

+ Specifies the command channel port where named + listens for connections from rndc. + The default is 953. +

+
-r randomfile
+

+ Specifies a source of random data for generating the + authorization. If the operating + system does not provide a /dev/random + or equivalent device, the default source of randomness + is keyboard input. randomdev + specifies + the name of a character device or file containing random + data to be used instead of the default. The special value + keyboard indicates that keyboard + input should be used. +

+
-s address
+

+ Specifies the IP address where named + listens for command channel connections from + rndc. The default is the loopback + address 127.0.0.1. +

+
-t chrootdir
+

+ Used with the -a option to specify + a directory where named will run + chrooted. An additional copy of the rndc.key + will be written relative to this directory so that + it will be found by the chrooted named. +

+
-u user
+

+ Used with the -a option to set the + owner + of the rndc.key file generated. + If + -t is also specified only the file + in + the chroot area has its owner changed. +

+
+
+
+

EXAMPLES

+

+ To allow rndc to be used with + no manual configuration, run +

+

rndc-confgen -a +

+

+ To print a sample rndc.conf file and + corresponding controls and key + statements to be manually inserted into named.conf, + run +

+

rndc-confgen +

It supersedes the +\fBndc\fR +utility that was provided in old BIND releases. If +\fBrndc\fR +is invoked with no command line options or arguments, it prints a short summary of the supported commands and the available options and their arguments. +.PP +\fBrndc\fR +communicates with the name server over a TCP connection, sending commands authenticated with digital signatures. In the current versions of +\fBrndc\fR +and +\fBnamed\fR, the only supported authentication algorithm is HMAC\-MD5, which uses a shared secret on each end of the connection. This provides TSIG\-style authentication for the command request and the name server's response. All commands sent over the channel must be signed by a key_id known to the server. +.PP +\fBrndc\fR +reads a configuration file to determine how to contact the name server and decide what algorithm and key it should use. +.SH "OPTIONS" +.PP +\-b \fIsource\-address\fR +.RS 4 +Use +\fIsource\-address\fR +as the source address for the connection to the server. Multiple instances are permitted to allow setting of both the IPv4 and IPv6 source addresses. +.RE +.PP +\-c \fIconfig\-file\fR +.RS 4 +Use +\fIconfig\-file\fR +as the configuration file instead of the default, +\fI/etc/rndc.conf\fR. +.RE +.PP +\-k \fIkey\-file\fR +.RS 4 +Use +\fIkey\-file\fR +as the key file instead of the default, +\fI/etc/rndc.key\fR.

If no server is supplied on the command line, the host named by the default\-server clause in the options statement of the +\fBrndc\fR +configuration file will be used. +.RE +.PP +\-p \fIport\fR +.RS 4 +Send commands to TCP port +\fIport\fR +instead of BIND 9's default control channel port, 953. +.RE +.PP +\-V +.RS 4 +Enable verbose logging. +.RE +.PP +\-y \fIkey_id\fR +.RS 4 +Use the key +\fIkey_id\fR +from the configuration file. +\fIkey_id\fR +must be known by named with the same algorithm and secret string in order for control message validation to succeed. If no +\fIkey_id\fR +is specified, +\fBrndc\fR +will first look for a key clause in the server statement of the server being used, or if no server statement is present for that host, then the default\-key clause of the options statement. Note that the configuration file contains shared secrets which are used to send authenticated control commands to name servers. It should therefore not have general read or write access. +.RE +.PP +For the complete set of commands supported by +\fBrndc\fR, see the BIND 9 Administrator Reference Manual or run +\fBrndc\fR +without arguments to see its help message. +.SH "LIMITATIONS" +.PP +\fBrndc\fR +does not yet support all the commands of the BIND 8 +\fBndc\fR +utility. +.PP +There is currently no way to provide the shared secret for a +\fBkey_id\fR +without using the configuration file. +.PP +Several error messages could be clearer. +.SH "SEE ALSO" +.PP +\fBrndc.conf\fR(5), +\fBrndc\-confgen\fR(8), +\fBnamed\fR(8), +\fBnamed.conf\fR(5), +\fBndc\fR(8), +BIND 9 Administrator Reference Manual. +.SH "AUTHOR" +.PP +Internet Systems Consortium +.SH "COPYRIGHT" +Copyright \(co 2004, 2005, 2007 Internet Systems Consortium, Inc.

DESCRIPTION

+

rndc.conf is the configuration file + for rndc, the BIND 9 name server control + utility. This file has a similar structure and syntax to + named.conf. Statements are enclosed + in braces and terminated with a semi-colon. Clauses in + the statements are also semi-colon terminated. The usual + comment styles are supported: +

+

+ C style: /* */ +

+

+ C++ style: // to end of line +

+

+ Unix style: # to end of line +

+

rndc.conf is much simpler than + named.conf. The file uses three + statements: an options statement, a server statement + and a key statement. +

+

+ The options statement contains five clauses. + The default-server clause is followed by the + name or address of a name server. This host will be used when + no name server is given as an argument to + rndc. The default-key + clause is followed by the name of a key which is identified by + a key statement. If no + keyid is provided on the rndc command line, + and no key clause is found in a matching + server statement, this default key will be + used to authenticate the server's commands and responses. The + default-port clause is followed by the port + to connect to on the remote name server. If no + port option is provided on the rndc command + line, and no port clause is found in a + matching server statement, this default port + will be used to connect. + The default-source-address and + default-source-address-v6 clauses which + can be used to set the IPv4 and IPv6 source addresses + respectively. +

+

+ After the server keyword, the server + statement includes a string which is the hostname or address + for a name server. The statement has three possible clauses: + key, port and + addresses. The key name must match the + name of a key statement in the file. The port number + specifies the port to connect to. If an addresses + clause is supplied these addresses will be used instead of + the server name. Each address can take an optional port. + If an source-address or source-address-v6 + of supplied then these will be used to specify the IPv4 and IPv6 + source addresses respectively. +

+

+ The key statement begins with an identifying + string, the name of the key. The statement has two clauses. + algorithm identifies the encryption algorithm + for rndc to use; currently only HMAC-MD5 + is + supported. This is followed by a secret clause which contains + the base-64 encoding of the algorithm's encryption key. The + base-64 string is enclosed in double quotes. +

+

+ There are two common ways to generate the base-64 string for the + secret. The BIND 9 program rndc-confgen + can + be used to generate a random key, or the + mmencode program, also known as + mimencode, can be used to generate a + base-64 + string from known input. mmencode does + not + ship with BIND 9 but is available on many systems. See the + EXAMPLE section for sample command lines for each. +

+
+
+

EXAMPLE

+
+      options {
+        default-server  localhost;
+        default-key     samplekey;
+      };
+
+

+

+
+      server localhost {
+        key             samplekey;
+      };
+
+

+

+
+      server testserver {
+        key		testkey;
+        addresses	{ localhost port 5353; };
+      };
+
+

+

+
+      key samplekey {
+        algorithm       hmac-md5;
+        secret          "6FMfj43Osz4lyb24OIe2iGEz9lf1llJO+lz";
+      };
+
+

+

+
+      key testkey {
+        algorithm	hmac-md5;
+        secret		"R3HI8P6BKw9ZwXwN3VZKuQ==";
+      };
+
+

+

+

+ In the above example, rndc will by + default use + the server at localhost (127.0.0.1) and the key called samplekey. + Commands to the localhost server will use the samplekey key, which + must also be defined in the server's configuration file with the + same name and secret. The key statement indicates that samplekey + uses the HMAC-MD5 algorithm and its secret clause contains the + base-64 encoding of the HMAC-MD5 secret enclosed in double quotes. +

+

+ If rndc -s testserver is used then rndc will + connect to server on localhost port 5353 using the key testkey. +

+

+ To generate a random secret with rndc-confgen: +

+

rndc-confgen +

+

+ A complete rndc.conf file, including + the + randomly generated key, will be written to the standard + output. Commented-out key and + controls statements for + named.conf are also printed. +

+

+ To generate a base-64 secret with mmencode: +

+

echo "known plaintext for a secret" | mmencode +

+
+
+

NAME SERVER CONFIGURATION

+

+ The name server must be configured to accept rndc connections and + to recognize the key specified in the rndc.conf + file, using the controls statement in named.conf. + See the sections on the controls statement in the + BIND 9 Administrator Reference Manual for details. +

Name

+

Synopsis

+

rndc [-b source-address] [-c config-file] [-k key-file] [-s server] [-p port] [-V] [-y key_id] {command}

+
+
+

DESCRIPTION

+

rndc + controls the operation of a name + server. It supersedes the ndc utility + that was provided in old BIND releases. If + rndc is invoked with no command line + options or arguments, it prints a short summary of the + supported commands and the available options and their + arguments. +

+

rndc + communicates with the name server + over a TCP connection, sending commands authenticated with + digital signatures. In the current versions of + rndc and named, + the only supported authentication algorithm is HMAC-MD5, + which uses a shared secret on each end of the connection. + This provides TSIG-style authentication for the command + request and the name server's response. All commands sent + over the channel must be signed by a key_id known to the + server. +

+

rndc + reads a configuration file to + determine how to contact the name server and decide what + algorithm and key it should use. +

+
+
+

OPTIONS

+
+
-b source-address
+

+ Use source-address + as the source address for the connection to the server. + Multiple instances are permitted to allow setting of both + the IPv4 and IPv6 source addresses. +

+
-c config-file
+

+ Use config-file + as the configuration file instead of the default, + /etc/rndc.conf. +

+
-k key-file
+

+ Use key-file + as the key file instead of the default, + /etc/rndc.key. The key in + /etc/rndc.key will be used to + authenticate + commands sent to the server if the config-file + does not exist. +

+
-s server
+

server is + the name or address of the server which matches a + server statement in the configuration file for + rndc. If no server is supplied on the + command line, the host named by the default-server clause + in the options statement of the rndc + configuration file will be used. +

+
-p port
+

+ Send commands to TCP port + port + instead + of BIND 9's default control channel port, 953. +

+
-V
+

+ Enable verbose logging. +

+
-y key_id
+

+ Use the key key_id + from the configuration file. + key_id + must be + known by named with the same algorithm and secret string + in order for control message validation to succeed. + If no key_id + is specified, rndc will first look + for a key clause in the server statement of the server + being used, or if no server statement is present for that + host, then the default-key clause of the options statement. + Note that the configuration file contains shared secrets + which are used to send authenticated control commands + to name servers. It should therefore not have general read + or write access. +

+
+

+ For the complete set of commands supported by rndc, + see the BIND 9 Administrator Reference Manual or run + rndc without arguments to see its help + message. +

+
+
+

LIMITATIONS

+

rndc + does not yet support all the commands of + the BIND 8 ndc utility. +

+

+ There is currently no way to provide the shared secret for a + key_id without using the configuration file. +

+

+ Several error messages could be clearer. +

+

Overview + +The goal of domain names is to provide a mechanism for naming resources +in such a way that the names are usable in different hosts, networks, +protocol families, internets, and administrative organizations. + +From the user's point of view, domain names are useful as arguments to a +local agent, called a resolver, which retrieves information associated +with the domain name. Thus a user might ask for the host address or +mail information associated with a particular domain name. To enable +the user to request a particular type of information, an appropriate +query type is passed to the resolver with the domain name. To the user, +the domain tree is a single information space; the resolver is +responsible for hiding the distribution of data among name servers from +the user. + +From the resolver's point of view, the database that makes up the domain +space is distributed among various name servers. Different parts of the +domain space are stored in different name servers, although a particular +data item will be stored redundantly in two or more name servers. The +resolver starts with knowledge of at least one name server. When the +resolver processes a user query it asks a known name server for the +information; in return, the resolver either receives the desired +information or a referral to another name server. Using these +referrals, resolvers learn the identities and contents of other name +servers. Resolvers are responsible for dealing with the distribution of +the domain space and dealing with the effects of name server failure by +consulting redundant databases in other servers. + +Name servers manage two kinds of data. The first kind of data held in +sets called zones; each zone is the complete database for a particular +"pruned" subtree of the domain space. This data is called +authoritative. A name server periodically checks to make sure that its +zones are up to date, and if not, obtains a new copy of updated zones + + + +Mockapetris [Page 3] + +RFC 1035 Domain Implementation and Specification November 1987 + + +from master files stored locally or in another name server. The second +kind of data is cached data which was acquired by a local resolver. +This data may be incomplete, but improves the performance of the +retrieval process when non-local data is repeatedly accessed. Cached +data is eventually discarded by a timeout mechanism. + +This functional structure isolates the problems of user interface, +failure recovery, and distribution in the resolvers and isolates the +database update and refresh problems in the name servers. + +2.2. Common configurations + +A host can participate in the domain name system in a number of ways, +depending on whether the host runs programs that retrieve information +from the domain system, name servers that answer queries from other +hosts, or various combinations of both functions. The simplest, and +perhaps most typical, configuration is shown below: + + Local Host | Foreign + | + +---------+ +----------+ | +--------+ + | | user queries | |queries | | | + | User |-------------->| |---------|->|Foreign | + | Program | | Resolver | | | Name | + | |<--------------| |<--------|--| Server | + | | user responses| |responses| | | + +---------+ +----------+ | +--------+ + | A | + cache additions | | references | + V | | + +----------+ | + | cache | | + +----------+ | + +User programs interact with the domain name space through resolvers; the +format of user queries and user responses is specific to the host and +its operating system. User queries will typically be operating system +calls, and the resolver and its cache will be part of the host operating +system. Less capable hosts may choose to implement the resolver as a +subroutine to be linked in with every program that needs its services. +Resolvers answer user queries with information they acquire via queries +to foreign name servers and the local cache. + +Note that the resolver may have to make several queries to several +different foreign name servers to answer a particular user query, and +hence the resolution of a user query may involve several network +accesses and an arbitrary amount of time. The queries to foreign name +servers and the corresponding responses have a standard format described + + + +Mockapetris [Page 4] + +RFC 1035 Domain Implementation and Specification November 1987 + + +in this memo, and may be datagrams. + +Depending on its capabilities, a name server could be a stand alone +program on a dedicated machine or a process or processes on a large +timeshared host. A simple configuration might be: + + Local Host | Foreign + | + +---------+ | + / /| | + +---------+ | +----------+ | +--------+ + | | | | |responses| | | + | | | | Name |---------|->|Foreign | + | Master |-------------->| Server | | |Resolver| + | files | | | |<--------|--| | + | |/ | | queries | +--------+ + +---------+ +----------+ | + +Here a primary name server acquires information about one or more zones +by reading master files from its local file system, and answers queries +about those zones that arrive from foreign resolvers. + +The DNS requires that all zones be redundantly supported by more than +one name server. Designated secondary servers can acquire zones and +check for updates from the primary server using the zone transfer +protocol of the DNS. This configuration is shown below: + + Local Host | Foreign + | + +---------+ | + / /| | + +---------+ | +----------+ | +--------+ + | | | | |responses| | | + | | | | Name |---------|->|Foreign | + | Master |-------------->| Server | | |Resolver| + | files | | | |<--------|--| | + | |/ | | queries | +--------+ + +---------+ +----------+ | + A |maintenance | +--------+ + | +------------|->| | + | queries | |Foreign | + | | | Name | + +------------------|--| Server | + maintenance responses | +--------+ + +In this configuration, the name server periodically establishes a +virtual circuit to a foreign name server to acquire a copy of a zone or +to check that an existing copy has not changed. The messages sent for + + + +Mockapetris [Page 5] + +RFC 1035 Domain Implementation and Specification November 1987 + + +these maintenance activities follow the same form as queries and +responses, but the message sequences are somewhat different. + +The information flow in a host that supports all aspects of the domain +name system is shown below: + + Local Host | Foreign + | + +---------+ +----------+ | +--------+ + | | user queries | |queries | | | + | User |-------------->| |---------|->|Foreign | + | Program | | Resolver | | | Name | + | |<--------------| |<--------|--| Server | + | | user responses| |responses| | | + +---------+ +----------+ | +--------+ + | A | + cache additions | | references | + V | | + +----------+ | + | Shared | | + | database | | + +----------+ | + A | | + +---------+ refreshes | | references | + / /| | V | + +---------+ | +----------+ | +--------+ + | | | | |responses| | | + | | | | Name |---------|->|Foreign | + | Master |-------------->| Server | | |Resolver| + | files | | | |<--------|--| | + | |/ | | queries | +--------+ + +---------+ +----------+ | + A |maintenance | +--------+ + | +------------|->| | + | queries | |Foreign | + | | | Name | + +------------------|--| Server | + maintenance responses | +--------+ + +The shared database holds domain space data for the local name server +and resolver. The contents of the shared database will typically be a +mixture of authoritative data maintained by the periodic refresh +operations of the name server and cached data from previous resolver +requests. The structure of the domain data and the necessity for +synchronization between name servers and resolvers imply the general +characteristics of this database, but the actual format is up to the +local implementor. + + + + +Mockapetris [Page 6] + +RFC 1035 Domain Implementation and Specification November 1987 + + +Information flow can also be tailored so that a group of hosts act +together to optimize activities. Sometimes this is done to offload less +capable hosts so that they do not have to implement a full resolver. +This can be appropriate for PCs or hosts which want to minimize the +amount of new network code which is required. This scheme can also +allow a group of hosts can share a small number of caches rather than +maintaining a large number of separate caches, on the premise that the +centralized caches will have a higher hit ratio. In either case, +resolvers are replaced with stub resolvers which act as front ends to +resolvers located in a recursive server in one or more name servers +known to perform that service: + + Local Hosts | Foreign + | + +---------+ | + | | responses | + | Stub |<--------------------+ | + | Resolver| | | + | |----------------+ | | + +---------+ recursive | | | + queries | | | + V | | + +---------+ recursive +----------+ | +--------+ + | | queries | |queries | | | + | Stub |-------------->| Recursive|---------|->|Foreign | + | Resolver| | Server | | | Name | + | |<--------------| |<--------|--| Server | + +---------+ responses | |responses| | | + +----------+ | +--------+ + | Central | | + | cache | | + +----------+ | + +In any case, note that domain components are always replicated for +reliability whenever possible. + +2.3. Conventions + +The domain system has several conventions dealing with low-level, but +fundamental, issues. While the implementor is free to violate these +conventions WITHIN HIS OWN SYSTEM, he must observe these conventions in +ALL behavior observed from other hosts. + +2.3.1. Preferred name syntax + +The DNS specifications attempt to be as general as possible in the rules +for constructing domain names. The idea is that the name of any +existing object can be expressed as a domain name with minimal changes. + + + +Mockapetris [Page 7] + +RFC 1035 Domain Implementation and Specification November 1987 + + +However, when assigning a domain name for an object, the prudent user +will select a name which satisfies both the rules of the domain system +and any existing rules for the object, whether these rules are published +or implied by existing programs. + +For example, when naming a mail domain, the user should satisfy both the +rules of this memo and those in RFC-822. When creating a new host name, +the old rules for HOSTS.TXT should be followed. This avoids problems +when old software is converted to use domain names. + +The following syntax will result in fewer problems with many + +applications that use domain names (e.g., mail, TELNET). + + ::= | " " + + ::=
