If any problems are discovered, +error messages are displayed on +.I stderr +and +.B nslint +exits with a non-zero status. +.LP +Here is a short list of errors +.B nslint +detects: +.IP +Records that are malformed. +.IP +Names that contain dots but are missing a trailing dot. +.IP +.B PTR +records with names that are missing a trailing dot. +.IP +Names that contain illegal characters (rfc1034). +.IP +.B A +records +without matching +.B PTR +records +.IP +.B PTR +records +without matching +.B A +records +.IP +Names with more than one address on the same subnet. +.IP +Addresses in use by more than one name. +.IP +Names with +.B CNAME +and other records (rfc1033). +.IP +Unknown service and/or protocol keywords in +.B WKS +records. +.IP +Missing quotes. +.LP +.SH OPTIONS +.TP +.B -b +Specify an alternate +.I named.boot +file. The default is +.IR /etc/named.boot . +.TP +.TP +.B -c +Specify an alternate +.I named.conf +file. The default is +.IR /etc/named.conf . +.TP +.B -B +Specify an alternate +.I nslint.boot +file. The default is +.I nslint.boot +in the last +.B directory +line processed in +.I named.boot +(or the current working directory). +This file is processed like a second +.IR named.boot . +The most common use is to tell +.B nslint +about +.B A +records that match +.B PTR +records that point outside the domains listed in +.IR named.boot . +.TP +.B -C +Specify an alternate +.I nslint.conf +file. The default is +.I nslint.conf +in the last +.B directory +line processed in +.I named.conf +(or the current working directory). +This file is processed like a second +.IR named.conf . +.TP +.B -d +Raise the debugging level. Debugging information is +displayed on +.IR stdout . +.LP +.B Nslint +knows how to read old style +.I named.boot +and BIND 8's new +.I named.conf +files. If both files exist, +.B nslint +will prefer +.I named.conf +(on the theory that you forgot to delete +.I named.boot +when you upgraded to BIND 8). +.LP +.SH "ADVANCED CONFIGURATION" +There are some cases where it is necessary to use the +advanced configuration features of +.BR nslint . +Advanced configuration is done with the +.I nslint.boot +file. +.LP +The most common is when a site has a demilitarized zone (DMZ). +The problem here is that the DMZ network will have +.B PTR +records for hosts outside its domain. For example lets say +we have +.I 128.0.rev +with: +.LP +.RS +.nf +.sp .5 +1.1 604800 in ptr gateway.lbl.gov. +2.1 604800 in ptr gateway.es.net. +.sp .5 +.fi +.RE +.LP +Obviously we will define an +.B A +record for +.I gateway.lbl.gov +pointing to +.I 128.0.1.1 +but we will get errors because there is no +.B A +record defined for +.IR gateway.es.net . +The solution is to create a +.I nslint.boot +file (in the same directory as the other dns files) +with: +.LP +.RS +.nf +.sp .5 +primary es.net nslint.es.net +.sp .5 +.fi +.RE +.LP +And then create the file +.I nslint.es.net +with: +.LP +.RS +.nf +.sp .5 +gateway 1 in a 128.0.1.2 +.sp .5 +.fi +.RE +.LP +Another problem occurs when there is a +.B CNAME +that points to a host outside the local domains. Let's say we have +.I info.lbl.gov +pointing to +.IR larry.es.net : +.LP +.RS +.nf +.sp .5 +info 604800 in cname larry.es.net. +.sp .5 +.fi +.RE +.LP +In this case we would need: +.LP +.RS +.nf +.sp .5 +primary es.net nslint.es.net +.sp .5 +.fi +.RE +.LP +in +.I nslint.boot +and: +.LP +.RS +.nf +.sp .5 +larry 1 in txt "place holder" +.sp .5 +.fi +.RE +.LP +.IR nslint.es.net . +.LP +One last problem +when a pseudo host is setup to allow two more +more actual hosts provide a service. For, let's say that +.I lbl.gov +contains: +.LP +.RS +.nf +.sp .5 +server 604800 in a 128.0.6.6 +server 604800 in a 128.0.6.94 +; +tom 604800 in a 128.0.6.6 +tom 604800 in mx 0 lbl.gov. +; +jerry 604800 in a 128.0.6.94 +jerry 604800 in mx 0 lbl.gov. +.sp .5 +.fi +.RE +.LP +In this case +.B nslint +would complain about missing +.B PTR +records and ip addresses in use by more than one host. +To suppress these warnings, add you would the lines: +.LP +.RS +.nf +.sp .5 +primary lbl.gov nslint.lbl.gov +primary 0.128.in-addr.arpa nslint.128.0.rev +.sp .5 +.fi +.RE +.LP +to +.I nslint.boot +and create +.I nslint.lbl.gov +with: +.LP +.RS +.nf +.sp .5 +server 1 in allowdupa 128.0.6.6 +server 1 in allowdupa 128.0.6.94 +.sp .5 +.fi +.RE +.LP +and create +.I nslint.128.0.rev +with: +.LP +.RS +.nf +.sp .5 +6.6 604800 in ptr server.lbl.gov. +94.6 604800 in ptr server.lbl.gov. +.sp .5 +.fi +.RE +.LP +In this example, the +.B allowdupa +keyword tells +.B nslint +that it's ok for +.I 128.0.6.6 +and +.I 128.0.6.94 +to be shared by +.IR server.lbl.gov , +.IR tom.lbl.gov , +and +.IR jerry.lbl.gov . +.LP +One last +.B nslint +feature helps detect hosts that have mistakenly had two ip addresses +assigned on the same subnet. This can happen when two different +people request an ip address for the same hostname or when someone +forgets an address has been assigned and requests a new number. +.LP +To detect such +.B A +records, add a +.B nslint +section to your +.I nslint.conf +containing something similar to: +.LP +.RS +.nf +.sp .5 +nslint { +.RS +network "128.0.6/22"; +network "128.0.6 255.255.252.0"; +.RE +}; +.sp .5 +.fi +.RE +.LP +The two network lines in this example are equivalent ways of saying the same +thing; that subnet +.I 128.0.6 +has a 22 bit wide subnet mask. +.LP +If you are using +.IR nslint.boot , +the syntax would be: +.LP +.RS +.nf +.sp .5 +network 128.0.6/22 +network 128.0.6 255.255.252.0 +.sp .5 +.fi +.RE +.LP +Again this shows two ways of saying the same thing. +.LP +Using information from the above +.B network +statement, +.B nslint +would would flag the following +.B A +records as being in error: +.LP +.RS +.nf +.sp .5 +server 1 in a 128.0.6.48 +server 1 in a 128.0.7.16 +.sp .5 +.fi +.RE +.LP +Note that if you specify any +.B network +lines in your +.I nslint.conf +or +.I nslint.boot +files, +.B nslint +requires you to include lines for all networks; +otherwise you might forget to add +.B network +lines for new networks. +.LP +.SH FILES +.na +.nh +.nf +/etc/named.boot - default named configuration file +nslint.boot - default nslint configuration file +.ad +.hy +.fi +.LP +.SH "SEE ALSO" +.na +.nh +.IR named (8), +rfc1033, +rfc1034 +.ad +.hy +.SH AUTHOR +Craig Leres of the +Lawrence Berkeley National Laboratory, University of California, Berkeley, CA. +.LP +The current version is available via anonymous ftp: +.LP +.RS +.I ftp://ftp.ee.lbl.gov/nslint.tar.gz +.RE +.SH BUGS +Please send bug reports to nslint@ee.lbl.gov. +.LP +Not everyone is guaranteed to agree with all the checks done. diff --git a/contrib/nslint-2.1a3/nslint.c b/contrib/nslint-2.1a3/nslint.c new file mode 100644 index 0000000..8ce9505 --- /dev/null +++ b/contrib/nslint-2.1a3/nslint.c @@ -0,0 +1,2382 @@ +/* + * Copyright (c) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001 + * The Regents of the University of California.
