---------------------------------------------------------------------------
+Version 4.5.8 [v4-beta] (rgerhards), 2010-01-??
+- (slightly) enhanced support for FreeBSD by setting _PATH_MODDIR to
+ the correct value on FreeBSD.
+ Thanks to Cristiano for the patch.
+- bugfix: -d did not enable display of debug messages
+ regression from introduction of "debug on demand" mode
+ Thanks to Michael Biebl for reporting this bug
+- bugfix: blanks inside file names did not terminate file name parsing.
+ This could reslult in the whole rest of a line (including comments)
+ to be treated as file name in "write to file" actions.
+ Thanks to Jack for reporting this issue.
+- bugfix: rsyslog hang when writing to a named pipe which nobody was
+ reading. Thanks to Michael Biebl for reporting this bug.
+- bugfix: memory leak when sending messages in zip-compressed format
+ Thanks to Naoya Nakazawa for analyzing this issue and providing a patch.
+- bugfix: potential segfaults during queue shutdown
+ (bugs require certain non-standard settings to appear)
+ Thanks to varmojfekoj for the patch
+---------------------------------------------------------------------------
+Version 4.5.7 [v4-beta] (rgerhards), 2009-11-18
+- added a so-called "On Demand Debug" mode, in which debug output can
+ be generated only after the process has started, but not right from
+ the beginning. This is assumed to be useful for hard-to-find bugs.
+ Also improved the doc on the debug system.
+- bugfix (kind of): check if TCP connection is still alive if using TLS
+ Thanks to Jonathan Bond-Caron for the patch.
+- bugfix: hostname accidently set to IP address for some message sources,
+ for example imudp. Thanks to Anton for reporting this bug.
+- bugfix [imported from 4.4.3]: $ActionExecOnlyOnceEveryInterval did
+ not work.
+---------------------------------------------------------------------------
+Version 4.5.6 [v4-beta] (rgerhards), 2009-11-05
+- bugfix: named pipes did no longer work (they always got an open error)
+ this was a regression from the omfile rewrite in 4.5.0
+- bugfix(minor): diag function returned wrong queue memeber count
+ for the main queue if an active DA queue existed. This had no relevance
+ to real deployments (assuming they are not running the debug/diagnostic
+ module...), but sometimes caused grief and false alerts in the
+ testbench.
+- included some important fixes from v4-stable:
+ * bugfix: invalid handling of zero-sized messages
+ * bugfix: zero-sized UDP messages are no longer processed
+ * bugfix: random data could be appended to message
+ * bugfix: reverse lookup reduction logic in imudp do DNS queries too often
+- bugfix(testbench): testcase did not properly wait for rsyslod shutdown
+ thus some unpredictable behavior and a false negative test result
+ could occur. [BACKPORTED from v5]
+- bugfix(testbench): sequence check was not always performed correctly,
+ that could result in tests reporting success when they actually failed
+---------------------------------------------------------------------------
+Version 4.5.5 [v4-beta] (rgerhards), 2009-10-21
+- added $InputTCPServerNotifyOnConnectionClose config directive
+ see doc for details
+- bugfix: debug string larger than 1K were improperly displayed. Max size
+ is now 32K
+- bugfix: invalid storage class selected for some size config parameters.
+ This resulted in wrong values. The most prominent victim was the
+ directory creation mode, which was set to zero in some cases. For
+ details, see related blog post:
+ http://blog.gerhards.net/2009/10/another-note-on-hard-to-find-bugs.html
+---------------------------------------------------------------------------
+Version 4.5.4 [v4-beta] (rgerhards), 2009-09-29
+- bugfix: potential segfault in stream writer on destruction
+ Most severely affected omfile. The problem was that some buffers were
+ freed before the asynchronous writer thread was shut down. So the
+ writer thread accessed invalid data, which may even already be
+ overwritten. Symptoms (with omfile) were segfaults, grabled data
+ and files with random names placed around the file system (most
+ prominently into the root directory). Special thanks to Aaron for
+ helping to track this down.
+- bugfix: potential race in object loader (obj.c) during use/release
+ of object interface
+- bugfixes: potential problems in out file zip writer. Problems could
+ lead to abort and/or memory leak. The module is now hardened in a very
+ conservative way, which is sub-optimal from a performance point of view.
+ This should be improved if it has proven reliable in practice.
+---------------------------------------------------------------------------
+Version 4.5.3 [v4-beta] (rgerhards), 2009-09-17
+- bugfix: repeated messages were incorrectly processed
+ this could lead to loss of the repeated message content. As a side-
+ effect, it could probably also be possible that some segfault occurs
+ (quite unlikely). The root cause was that some counters introduced
+ during the malloc optimizations were not properly duplicated in
+ MsgDup(). Note that repeated message processing is not enabled
+ by default.
+- bugfix: message sanitation had some issues:
+ - control character DEL was not properly escaped
+ - NUL and LF characters were not properly stripped if no control
+ character replacement was to be done
+ - NUL characters in the message body were silently dropped (this was
+ a regeression introduced by some of the recent optimizations)
+- bugfix: strings improperly reused, resulting in some message properties
+ be populated with strings from previous messages. This was caused by
+ an improper predicate check. [backported from v5]
+- fixed some minor portability issues
+- bugfix: reverse lookup reduction logic in imudp do DNS queries too often
+ [imported from 4.4.2]
+---------------------------------------------------------------------------
+Version 4.5.2 [v4-beta] (rgerhards), 2009-08-21
+- legacy syslog parser changed so that it now accepts date stamps in
+ wrong case. Some devices seem to create them and I do not see any harm
+ in supporting that.
+- added $InputTCPMaxListeners directive - permits to specify how many
+ TCP servers shall be possible (default is 20).
+- bugfix: memory leak with some input modules. Those inputs that
+ use parseAndSubmitMsg() leak two small memory blocks with every message.
+ Typically, those process only relatively few messages, so the issue
+ does most probably not have any effect in practice.
+- bugfix: if tcp listen port could not be created, no error message was
+ emitted
+- bugfix: potential segfault in output file writer (omfile)
+ In async write mode, we use modular arithmetic to index the output
+ buffer array. However, the counter variables accidently were signed,
+ thus resulting in negative indizes after integer overflow. That in turn
+ could lead to segfaults, but was depending on the memory layout of
+ the instance in question (which in turn depended on a number of
+ variables, like compile settings but also configuration). The counters
+ are now unsigned (as they always should have been) and so the dangling
+ mis-indexing does no longer happen. This bug potentially affected all
+ installations, even if only some may actually have seen a segfault.
+- bugfix: hostnames with dashes in them were incorrectly treated as
+ malformed, thus causing them to be treated as TAG (this was a regression
+ introduced from the "rfc3164 strict" change in 4.5.0).
+---------------------------------------------------------------------------
+Version 4.5.1 [DEVEL] (rgerhards), 2009-07-15
+- CONFIG CHANGE: $HUPisRestart default is now "off". We are doing this
+ to support removal of restart-type HUP in v5.
+- bugfix: fromhost-ip was sometimes truncated
+- bugfix: potential segfault when zip-compressed syslog records were
+ received (double free)
+- bugfix: properties inputname, fromhost, fromhost-ip, msg were lost when
+ working with disk queues
+- performance enhancement: much faster, up to twice as fast (depending
+ on configuration)
+- bugfix: abort condition when RecvFrom was not set and message reduction
+ was on. Happend e.g. with imuxsock.
+- added $klogConsoleLogLevel directive which permits to set a new
+ console log level while rsyslog is active
+- bugfix: message could be truncated after TAG, often when forwarding
+ This was a result of an internal processing error if maximum field
+ sizes had been specified in the property replacer.
+- added ability for the TCP output action to "rebind" its send socket after
+ sending n messages (actually, it re-opens the connection, the name is
+ used because this is a concept very similiar to $ActionUDPRebindInterval).
+ New config directive $ActionSendTCPRebindInterval added for the purpose.
+ By default, rebinding is disabled. This is considered useful for load
+ balancers.
+- testbench improvements
+---------------------------------------------------------------------------
+Version 4.5.0 [DEVEL] (rgerhards), 2009-07-02
+- activation order of inputs changed, they are now activated only after
+ privileges are dropped. Thanks to Michael Terry for the patch.
+- greatly improved performance
+- greatly reduced memory requirements of msg object
+ to around half of the previous demand. This means that more messages can
+ be stored in core! Due to fewer cache misses, this also means some
+ performance improvement.
+- improved config error messages: now contain a copy of the config line
+ that (most likely) caused the error
+- reduced max value for $DynaFileCacheSize to 1,000 (the former maximum
+ of 10,000 really made no sense, even 1,000 is very high, but we like
+ to keep the user in control ;)).
+- added capability to fsync() queue disk files for enhanced reliability
+ (also add's speed, because you do no longer need to run the whole file
+ system in sync mode)
+- more strict parsing of the hostname in rfc3164 mode, hopefully
+ removes false positives (but may cause some trouble with hostname
+ parsing). For details, see this bug tracker:
+ http://bugzilla.adiscon.com/show_bug.cgi?id=126
+- omfile rewrite to natively support zip files (includes large extension
+ of the stream class)
+- added configuration commands (see doc for explanations)
+ * $OMFileZipLevel
+ * $OMFileIOBufferSize
+ * $OMFileFlushOnTXEnd
+ * $MainMsgQueueSyncQueueFiles
+ * $ActionQueueSyncQueueFiles
+- done some memory accesses explicitely atomic
+- bugfix: subtle (and usually irrelevant) issue in timout processing
+ timeout could be one second too early if nanoseconds wrapped
+- set a more sensible timeout for shutdow, now 1.5 seconds to complete
+ processing (this also removes those cases where the shutdown message
+ was not written because the termination happened before it)
+- internal bugfix: object pointer was only reset to NULL when an object
+ was actually destructed. This most likely had no effect to existing code,
+ but it may also have caused trouble in remote cases. Similarly, the fix
+ may also cause trouble...
+- bugfix: missing initialization during timestamp creation
+ This could lead to timestamps written in the wrong format, but not to
+ an abort
+---------------------------------------------------------------------------
Version 4.4.3 [v4-stable] (rgerhards), 2009-10-??
- bugfix: several smaller bugs resolved after flexelint review
Thanks to varmojfekoj for the patch.

+<h2>Environment Variables</h2>
+<p>There are two environment variables that set several debug settings:
+<ul>
+<li>The "RSYSLOG_DEBUGLOG" (sample: &nbsp;RSYSLOG_DEBUGLOG="/path/to/debuglog/")
writes (allmost)
all debug message to the specified log file in addition to stdout. Some
system messages (e.g. segfault or abort message) are not written to the
-file as we can not capture them. Runtime debug support is controlled by
-"RSYSLOG_DEBUG". It contains an option string with the following
-options possible (all are case insensitive):</p><ul><li><span style="font-weight: bold;">LogFuncFlow</span> - print out the logical flow of functions (entering and exiting them)</li><li><span style="font-weight: bold;">FileTrace</span> - specifies which files to trace LogFuncFlow. If <span style="font-weight: bold;">not</span>
+file as we can not capture them.
+<li>Runtime debug support is controlled by "RSYSLOG_DEBUG".
+<p>The "RSYSLOG_DEBUG" environment variable contains an option string with the following
+options possible (all are case insensitive):</p>
+<ul>
+<li><b>LogFuncFlow</b> - print out the logical flow of functions (entering and exiting them)</li>
+<li><b>FileTrace</b> - specifies which files to trace LogFuncFlow. If <b>not</b>
set (the default), a LogFuncFlow trace is provided for all files. Set
to limit it to the files specified. FileTrace may be specified multiple
times, one file each (e.g. export RSYSLOG_DEBUG="LogFuncFlow
-FileTrace=vm.c FileTrace=expr.c"</li><li><span style="font-weight: bold;">PrintFuncDB</span> - print the content of the debug function database whenever debug information is printed (e.g. abort case)!</li><li><span style="font-weight: bold;">PrintAllDebugInfoOnExit</span> - print all debug information immediately before rsyslogd exits (<span style="font-weight: bold; font-style: italic;">currently not implemented!</span>)</li><li><span style="font-weight: bold;">PrintMutexAction</span> - print mutex action as it happens.

If RSYSLOG_DEBUGLOG is not set, this means no messages will be displayed at all.</li><li><span style="font-weight: bold;">help</span> - display a very short list of commands - hopefully a life saver if you can't access the documentation...</li></ul>

+</ul>
+</ul>
+<h3>Why Environment Variables?</h3>
+<p>You may ask why we use environment variables for debug-system parameters and not
+the usual rsyslog.conf configuration commands. After all, environment variables force one
+to change distro-specific configuration files, whereas regular configuration directives
+would fit nicely into the one central rsyslog.conf.
+<p>The problem here is that many settings of the debug system must be initialized
+before the full rsyslog engine starts up. At that point, there is no such thing like
+rsyslog.conf or the objects needed to process it present in an running instance.
+And even if we would enable to change settings some time later, that would mean that
+we can not correctly monitor (and debug) the initial startup phase of rsyslogd. What
+makes matters worse is that during this startup phase (and never again later!) some
+of the base debug structure needs to be created, at least if the build is
+configured for that (many of these things only happen in --enable-rtinst mode). So
+if we do not initialize the debug system <b>before</b> actually startig up the
+rsyslog core, we get a number of data structures wrong.
+<p>For these reasons, we utilize environment variables to initialize and configure
+the debugging system. We understand this may be somewhat painful, but now you know
+there are at least some good reasons for doing so.
+<h2>Getting debug information from a running Instance</h2>
+<p>It is possible to obtain debugging information from a running instance, but this requires
+some setup. We assume that the instance runs in the background, so debug output to
+stdout is not desired. As such, all debug information needs to go into a log file.
+<p>To create this setup, you need to
<ul>
+<li>point the RSYSLOG_DEBUGLOG environment variable to a file that is accessible
+during the while runtime (we strongly suggest a file in the local file system!)
+<li>set RSYSLOG_DEBUG at least to "DebugOnDeman NoStdOut"
+<li>make sure these environment variables are set in the correct (distro-specifc)
+startup script if you do not run rsyslogd interactively
</ul>
+<p>These settings enable the capability to react to SIGUSR1. The signal will toggle
+debug status when received. So send it one to turn debug loggin on, and send it again
+to turn debug logging off again. The third time it will be turned on again ... and so on.
+<p>On a typical system, you can signal rsyslogd as follows:
+<pre>
+kill -USR1 `cat /var/run/rsyslogd.pid`
+</pre>
+Important: there are backticks around the "cat"-command. If you use the regular
+quote it won't work. The debug log will show whether debug logging has been turned
+on or off. There is no other indication of the status.
+<p>Note: running with DebugOnDemand by itself does in practice not have any performance
+toll. However, switching debug logging on has a severe performance toll. Also, debug
+logging synchronizes much of the code, removing a lot of concurrency and thus
+potential race conditions. As such, the very same running instance may behave
+very differently with debug logging turned on vs. off. The on-demand debug log
+functionality is considered to be very valuable to analyze hard-to-find bugs that
+only manifest after a long runtime. Turning debug logging on a failing instance
+may reveal the cause of the failure. However, depending on the failure, debug logging
+may not even be successfully be turned on. Also note that with this rsyslog version we cannot
+obtain any debug information on events that happened <i>before</i> debug logging was
+turned on.
+<p>If an instance hangs, it is possible to obtain some useful information about the current
+threads and their calling stack by sending SIGUSR2. However, the usefulness of that
+information is very much depending on rsyslog compile-time settings, must importantly
+the --enable-rtinst configure flag. Note that activating this option causes additional overhead
+and slows down rsyslgod considerable. So if you do that, you need to check if it is
+capable to handle the workload. Also, threading behavior is modified by the
+runtime instrumentation.
+<p>Sending SIGUSR2 writes new process state information to the log file each time
+it is sent. So it may be useful to do that from time to time. It probably is most
+useful if the process seems to hang, in which case it may (may!) be able to output
+some diagnostic information on the current processing state. In that case, turning
+on the mutex debugging options (see above) is probably useful.
+<h2>Interpreting the Logs</h2>
+<p>Debug logs are primarily meant for rsyslog developers. But they may still provide valuable
+information to users. Just be warned that logs sometimes contains informaton the looks like
+an error, but actually is none. We put a lot of extra information into the logs, and there
+are some cases where it is OK for an error to happen, we just wanted to record it inside
+the log. The code handles many cases automatically. So, in short, the log may not make sense to
+you, but it (hopefully) makes sense to a developer. Note that we developers often need
+many lines of the log file, it is relatively rare that a problem can be diagnosed by
+looking at just a couple of (hundered) log records.
+<h2>Security Risks</h2>
+<p>The debug log will reveal potentially sensible information, including user accounts and
+passwords, to anyone able to read the log file. As such, it is recommended to properly
+guard access to the log file. Also, an instance running with debug log enabled runs much
+slower than one without. An attacker may use this to place carry out a denial-of-service
+attack or try to hide some information from the log file. As such, it is suggested to
+enable DebugOnDemand mode only for a reason. Note that when no debug mode is enabled,
+SIGUSR1 and SIGUSR2 are completely ignored.
+<p>When running in any of the debug modes (including on demand mode), an interactive
+instance of rsyslogd can be aborted by pressing ctl-c.

-
-
-<B>DESCRIPTION</B>
- <B>Rsyslogd </B>is a system utility providing support for message logging.
- Support of both internet and unix domain sockets enables this utility
- to support both local and remote logging (via UDP and TCP).
-
- <B>Rsyslogd</B>(8) is derived from the sysklogd package which in turn is
- derived from the stock BSD sources.
-
- <B>Rsyslogd </B>provides a kind of logging that many modern programs use.
- Every logged message contains at least a time and a hostname field,
- normally a program name field, too, but that depends on how trusty the
- logging program is. The rsyslog package supports free definition of
- output formats via templates. It also supports precise timestamps and
- writing directly to MySQL databases. If the database option is used,
- tools like phpLogCon can be used to view the log data.
-
- While the <B>rsyslogd </B>sources have been heavily modified a couple of notes
- are in order. First of all there has been a systematic attempt to
- insure that rsyslogd follows its default, standard BSD behavior. Of
- course, some configuration file changes are necessary in order to sup-
- port the template system. However, rsyslogd should be able to use a
- standard syslog.conf and act like the original syslogd. However, an
- original syslogd will not work correctly with a rsyslog-enhanced con-
- figuration file. At best, it will generate funny looking file names.
- The second important concept to note is that this version of rsyslogd
- interacts transparently with the version of syslog found in the stan-
- dard libraries. If a binary linked to the standard shared libraries
- fails to function correctly we would like an example of the anomalous
- behavior.
-
- The main configuration file <I>/etc/rsyslog.conf </I>or an alternative file,
- given with the <B>-f </B>option, is read at startup. Any lines that begin
- with the hash mark (‘‘#’’) and empty lines are ignored. If an error
- occurs during parsing the error element is ignored. It is tried to
- parse the rest of the line.
-
- For details and configuration examples, see the <B>rsyslog.conf (5) </B>man
- page.
-
-
-
-<B>OPTIONS</B>
- <B>-A </B>When sending UDP messages, there are potentially multiple paths
- to the target destination. By default, <B>rsyslogd </B>only sends to
- the first target it can successfully send to. If -A is given,
- messages are sent to all targets. This may improve reliability,
- but may also cause message duplication. This option should
- enabled only if it is fully understood.
-
- <B>-4 </B>Causes <B>rsyslogd </B>to listen to IPv4 addresses only. If neither -4
- nor -6 is given, <B>rsyslogd </B>listens to all configured addresses of
- the system.
-
- <B>-6 </B>Causes <B>rsyslogd </B>to listen to IPv6 addresses only. If neither -4
- nor -6 is given, <B>rsyslogd </B>listens to all configured addresses of
- the system.
-
- <B>-a </B><I>socket</I>
- Using this argument you can specify additional sockets from that
- <B>rsyslogd </B>has to listen to. This is needed if you’re going to
- let some daemon run within a chroot() environment. You can use
- up to 19 additional sockets. If your environment needs even
- more, you have to increase the symbol <B>MAXFUNIX </B>within the sys-
- logd.c source file. An example for a chroot() daemon is
- described by the people from OpenBSD at
- http://www.psionic.com/papers/dns.html.
-
- <B>-d </B>Turns on debug mode. Using this the daemon will not proceed a
- <B>fork</B>(2) to set itself in the background, but opposite to that
- stay in the foreground and write much debug information on the
- current tty. See the DEBUGGING section for more information.
-
- <B>-e </B>Set the default of $RepeatedMsgReduction config option to "off".
- Hine: "e" like "every message". For further information, see
- there.
-
- <B>-f </B><I>config file</I>
- Specify an alternative configuration file instead of <I>/etc/rsys-</I>
- <I>log.conf</I>, which is the default.
-
- <B>-h </B>By default rsyslogd will not forward messages it receives from
- remote hosts. Specifying this switch on the command line will
- cause the log daemon to forward any remote messages it receives
- to forwarding hosts which have been defined.
-
- <B>-i </B><I>pid file</I>
- Specify an alternative pid file instead of the default one.
- This option must be used if multiple instances of rsyslogd
- should run on a single machine.
-
- <B>-l </B><I>hostlist</I>
- Specify a hostname that should be logged only with its simple
- hostname and not the fqdn. Multiple hosts may be specified
- using the colon (‘‘:’’) separator.
-
- <B>-m </B><I>interval</I>
- The <B>rsyslogd </B>logs a mark timestamp regularly. The default
- <I>interval </I>between two <I>-- MARK -- </I>lines is 20 minutes. This can
- be changed with this option. Setting the <I>interval </I>to zero turns
- it off entirely.
-
- <B>-n </B>Avoid auto-backgrounding. This is needed especially if the
- <B>rsyslogd </B>is started and controlled by <B>init</B>(8).
-
- <B>-o </B>Omit reading the standard local log socket. This option is most
- useful for running multiple instances of rsyslogd on a single
- machine. When specified, no local log socket is opened at all.
-
- <B>-p </B><I>socket</I>
- You can specify an alternative unix domain socket instead of
- <I>/dev/log</I>.
-
- <B>-r </B><I>["port"]</I>
- Activates the syslog/udp listener service. The listener will
- listen to the specified port. If no port is specified, 0 is
- used as port number, which in turn will lead to a lookup of the
- system default syslog port. If there is no system default, 514
- is used. Please note that the port must immediately follow the
- -r option. Thus "-r514" is valid while "-r 514" is invalid (note
- the space).
-
- <B>-s </B><I>domainlist</I>
- Specify a domainname that should be stripped off before logging.
- Multiple domains may be specified using the colon (‘‘:’’) sepa-
- rator. Please be advised that no sub-domains may be specified
- but only entire domains. For example if <B>-s north.de </B>is speci-
- fied and the host logging resolves to satu.infodrom.north.de no
- domain would be cut, you will have to specify two domains like:
- <B>-s north.de:infodrom.north.de</B>.
-
- <B>-t </B><I>port,max-nbr-of-sessions</I>
- Activates the syslog/tcp listener service. The listener will
- listen to the specified port. If max-nbr-of-sessions is speci-
- fied, that becomes the maximum number of concurrent tcp ses-
- sions. If not specified, the default is 200. Please note that
- syslog/tcp is not standardized, but the implementation in rsys-
- logd follows common practice and is compatible with e.g. Cisco
- PIX, syslog-ng and MonitorWare (Windows). Please note that the
- port must immediately follow the -t option. Thus "-t514" is
- valid while "-t 514" is invalid (note the space).
-
- <B>-v </B>Print version and exit.
-
- <B>-w </B>Supress warnings issued when messages are received from non-
- authorized machines (those, that are in no AllowedSender list).
-
- <B>-x </B>Disable DNS for remote messages.
-
-
-<B>SIGNALS</B>
- <B>Rsyslogd </B>reacts to a set of signals. You may easily send a signal to
- <B>rsyslogd </B>using the following:
-
- kill -SIGNAL ‘cat /var/run/rsyslogd.pid‘
-
-
- <B>SIGHUP </B>This lets <B>rsyslogd </B>perform a re-initialization. All open files
- are closed, the configuration file (default is <I>/etc/rsys-</I>
- <I>log.conf</I>) will be reread and the <B>rsyslog</B>(3) facility is started
- again.
-
- <B>SIGTERM</B>
- <B>Rsyslogd </B>will die.
-
- <B>SIGINT</B>, <B>SIGQUIT</B>
- If debugging is enabled these are ignored, otherwise <B>rsyslogd</B>
- will die.
-
- <B>SIGUSR1</B>
- Switch debugging on/off. This option can only be used if <B>rsys-</B>
- <B>logd </B>is started with the <B>-d </B>debug option.
-
- <B>SIGCHLD</B>
- Wait for childs if some were born, because of wall’ing messages.
-
-
-<B>SUPPORT FOR REMOTE LOGGING</B>
- <B>Rsyslogd </B>provides network support to the syslogd facility. Network
- support means that messages can be forwarded from one node running
- rsyslogd to another node running rsyslogd (or a compatible syslog
- implementation) where they will be actually logged to a disk file.
-
- To enable this you have to specify either the <B>-r </B>or <B>-t </B>option on the
- command line. The default behavior is that <B>rsyslogd </B>won’t listen to
- the network. You can also combine these two options if you want rsys-
- logd to listen to both TCP and UDP messages.
-
- The strategy is to have rsyslogd listen on a unix domain socket for
- locally generated log messages. This behavior will allow rsyslogd to
- inter-operate with the syslog found in the standard C library. At the
- same time rsyslogd listens on the standard syslog port for messages
- forwarded from other hosts. To have this work correctly the <B>ser-</B>
- <B>vices</B>(5) files (typically found in <I>/etc</I>) must have the following entry:
-
- syslog 514/udp
-
- If this entry is missing <B>rsyslogd </B>will use the well known port of 514
- (so in most cases, it’s not really needed).
-
- To cause messages to be forwarded to another host replace the normal
- file line in the <I>rsyslog.conf </I>file with the name of the host to which
- the messages is to be sent prepended with an @ (for UDP delivery) or
- the sequence @@ (for TCP delivery). The host name can also be followed
- by a colon and a port number, in which case the message is sent to the
- specified port on the remote host.
-
- For example, to forward <B>ALL </B>messages to a remote host use the
- following <I>rsyslog.conf </I>entry:
-
- # Sample rsyslogd configuration file to
- # messages to a remote host forward all.
- *.* @hostname
- More samples can be found in sample.conf.
-
- If the remote hostname cannot be resolved at startup, because
- the name-server might not be accessible (it may be started after
- rsyslogd) you don’t have to worry. <B>Rsyslogd </B>will retry to
- resolve the name ten times and then complain. Another possibil-
- ity to avoid this is to place the hostname in <I>/etc/hosts</I>.
-
- With normal <B>syslogd</B>s you would get syslog-loops if you send out
- messages that were received from a remote host to the same host
- (or more complicated to a third host that sends it back to the
- first one, and so on).
-
- To avoid this no messages that were received from a remote host
- are sent out to another (or the same) remote host. You can dis-
- able this feature by the <B>-h </B>option.
-
- If the remote host is located in the same domain as the host,
- <B>rsyslogd </B>is running on, only the simple hostname will be logged
- instead of the whole fqdn.
-
- In a local network you may provide a central log server to have
- all the important information kept on one machine. If the net-
- work consists of different domains you don’t have to complain
- about logging fully qualified names instead of simple hostnames.
- You may want to use the strip-domain feature <B>-s </B>of this server.
- You can tell <B>rsyslogd </B>to strip off several domains other than
- the one the server is located in and only log simple hostnames.
-
- Using the <B>-l </B>option there’s also a possibility to define single
- hosts as local machines. This, too, results in logging only
- their simple hostnames and not the fqdns.
-
-
-<B>OUTPUT TO DATABASES</B>
- <B>Rsyslogd </B>has support for writing data to MySQL database tables. The
- exact specifics are described in the <B>rsyslog.conf (5) </B>man page. Be sure
- to read it if you plan to use database logging.
-
- While it is often handy to have the data in a database, you must be
- aware of the implications. Most importantly, database logging takes far
- longer than logging to a text file. A system that can handle a large
- log volume when writing to text files can most likely not handle a sim-
- ilar large volume when writing to a database table.
-
-
-<B>OUTPUT TO NAMED PIPES (FIFOs)</B>
- <B>Rsyslogd </B>has support for logging output to named pipes (fifos). A fifo
- or named pipe can be used as a destination for log messages by prepend-
- ing a pipy symbol (‘‘|’’) to the name of the file. This is handy for
- debugging. Note that the fifo must be created with the mkfifo command
- before <B>rsyslogd </B>is started.
-
- The following configuration file routes debug messages from the
- kernel to a fifo:
-
- # Sample configuration to route kernel debugging
- # messages ONLY to /usr/adm/debug which is a
- # named pipe.
- kern.=debug |/usr/adm/debug
-
-
-<B>INSTALLATION CONCERNS</B>
- There is probably one important consideration when installing rsyslogd.
- It is dependent on proper formatting of messages by the syslog func-
- tion. The functioning of the syslog function in the shared libraries
- changed somewhere in the region of libc.so.4.[2-4].n. The specific
- change was to null-terminate the message before transmitting it to the
- <I>/dev/log </I>socket. Proper functioning of this version of rsyslogd is
- dependent on null-termination of the message.
-
- This problem will typically manifest itself if old statically linked
- binaries are being used on the system. Binaries using old versions of
- the syslog function will cause empty lines to be logged followed by the
- message with the first character in the message removed. Relinking
- these binaries to newer versions of the shared libraries will correct
- this problem.
-
- The <B>rsyslogd</B>(8) can be run from <B>init</B>(8) or started as part of the rc.*
- sequence. If it is started from init the option <I>-n </I>must be set, other-
- wise you’ll get tons of syslog daemons started. This is because
- <B>init</B>(8) depends on the process ID.
-
-
-<B>SECURITY THREATS</B>
- There is the potential for the rsyslogd daemon to be used as a conduit
- for a denial of service attack. A rogue program(mer) could very easily
- flood the rsyslogd daemon with syslog messages resulting in the log
- files consuming all the remaining space on the filesystem. Activating
- logging over the inet domain sockets will of course expose a system to
- risks outside of programs or individuals on the local machine.
-
- There are a number of methods of protecting a machine:
-
- 1. Implement kernel firewalling to limit which hosts or networks
- have access to the 514/UDP socket.
-
- 2. Logging can be directed to an isolated or non-root filesystem
- which, if filled, will not impair the machine.
-
- 3. The ext2 filesystem can be used which can be configured to limit
- a certain percentage of a filesystem to usage by root only.
- <B>NOTE </B>that this will require rsyslogd to be run as a non-root
- process. <B>ALSO NOTE </B>that this will prevent usage of remote log-
- ging since rsyslogd will be unable to bind to the 514/UDP
- socket.
-
- 4. Disabling inet domain sockets will limit risk to the local
- machine.
-
- 5. Use step 4 and if the problem persists and is not secondary to a
- rogue program/daemon get a 3.5 ft (approx. 1 meter) length of
- sucker rod* and have a chat with the user in question.
-
- Sucker rod def. — 3/4, 7/8 or 1in. hardened steel rod, male
- threaded on each end. Primary use in the oil industry in West-
- ern North Dakota and other locations to pump ’suck’ oil from oil
- wells. Secondary uses are for the construction of cattle feed
- lots and for dealing with the occasional recalcitrant or bel-
- ligerent individual.
-
- <B>Message replay and spoofing</B>
- If remote logging is enabled, messages can easily be spoofed and
- replayed. As the messages are transmitted in clear-text, an attacker
- might use the information obtained from the packets for malicious
- things. Also, an attacker might reply recorded messages or spoof a
- sender’s IP address, which could lead to a wrong perception of system
- activity. Be sure to think about syslog network security before
- enabling it.
-
-
-<B>DEBUGGING</B>
- When debugging is turned on using <B>-d </B>option then <B>rsyslogd </B>will be very
- verbose by writing much of what it does on stdout. Whenever the con-
- figuration file is reread and re-parsed you’ll see a tabular, corre-
- sponding to the internal data structure. This tabular consists of four
- fields:
-
- <I>number </I>This field contains a serial number starting by zero. This num-
- ber represents the position in the internal data structure (i.e.
- the array). If one number is left out then there might be an
- error in the corresponding line in <I>/etc/rsyslog.conf</I>.
-
- <I>pattern</I>
- This field is tricky and represents the internal structure
- exactly. Every column stands for a facility (refer to <B>sys-</B>
- <B>log</B>(3)). As you can see, there are still some facilities left
- free for former use, only the left most are used. Every field
- in a column represents the priorities (refer to <B>syslog</B>(3)).
-
- <I>action </I>This field describes the particular action that takes place
- whenever a message is received that matches the pattern. Refer
- to the <B>syslog.conf</B>(5) manpage for all possible actions.
-
- <I>arguments</I>
- This field shows additional arguments to the actions in the last
- field. For file-logging this is the filename for the logfile;
- for user-logging this is a list of users; for remote logging
- this is the hostname of the machine to log to; for console-log-
- ging this is the used console; for tty-logging this is the spec-
- ified tty; wall has no additional arguments.
-
-
- <B>templates</B>
- There will also be a second internal structure which lists all
- defined templates and there contents. This also enables you to
- see the internally-defined, hardcoded templates.
-
-<B>FILES</B>
- <I>/etc/rsyslog.conf</I>
- Configuration file for <B>rsyslogd</B>. See <B>rsyslog.conf</B>(5) for exact
- information.

+<title>Multiple Rulesets in rsyslog</title></head>
+<body>
+<h1>Multiple Rulesets in rsyslog</h1>
+<p>Starting with version 4.5.0 and 5.1.1, <a href="http://www.rsyslog.com">rsyslog</a> supports
+multiple rulesets within a single configuration.
+This is especially useful for routing the recpetion of remote messages to a set of specific rules.
+Note that the input module must support binding to non-standard rulesets, so the functionality
+may not be available with all inputs.
+<p>In this document, I am using <a href="imtcp.html">imtcp</a>, an input module
+that supports binding to non-standard rulesets since rsyslog started to support them.
+<h2>What is a Ruleset?</h2>
+If you have worked with (r)syslog.conf, you know that it is made up of what I call rules (others
+tend to call them selectors, a sysklogd term). Each rule consist of a filter and one or more
+actions to be carried out when the filter evaluates to true. A filter may be as simple as a
+traditional
+syslog priority based filter (like &quot;*.*&quot; or &quot;mail.info&quot; or a as complex as a
+script-like expression. Details on that are covered in the config file documentation. After the
+filter come action specifiers, and an action is something that does something to a message, e.g.
+write it to a file or forward it to a remote logging server.
+
+<p>A traditional configuration file is made up of one or more of these rules. When a new
+message arrives, its processing starts with the first rule (in order of appearance in
+rsyslog.conf) and continues for each rule until either all rules have been processed or
+a so-called &quote;discard&quot; action happens, in which case processing stops and the
+message is thrown away (what also happens after the last rule has been processed).
+
+<p>The <b>multi-ruleset</b> support now permits to specify more than one such rule sequence.
+You can think of a traditional config file just as a single default rule set, which is
+automatically bound to each of the inputs. This is even what actually happens. When
+rsyslog.conf is processed, the config file parser looks for the directive
+
+<pre>$RuleSet &lt;name&gt;
+</pre>
+
+<p>Where name is any name the user likes (but must not start with &quot;RSYSLOG_&quot;, which
+is the name space reserved for rsyslog use). If it finds this directive, it begins a new
+rule set (if the name was not yet know) or switches to an already-existing one (if the name
+was known). All rules defined between this $RuleSet directive and the next one are appended
+to the named ruleset. Note that the reserved name "RSYSLOG_DefaultRuleset" is used to
+specify rsyslogd's default ruleset. You can use that name whereever you can use a ruleset name,
+including when binding an input to it.
+
+<p>Inside a ruleset, messages are processed as described above: they start with the first rule
+and rules are processed in the order of appearance of the configuration file until either
+there are no more rules or the discard action is executed. Note that with multiple rulesets
+no longer <b>all</b> rsyslog.conf rules are executed but <b>only</b> those that are
+contained within the specific ruleset.
+
+<p>Inputs must explicitely bind to rulesets. If they don't do, the default ruleset is bound.
+
+<p>This brings up the next question:
+
+<h2>What does &quot;To bind to a Ruleset&quot; mean?</h2>
+<p>This term is used in the same sense as &quot;to bind an IP address to an interface&quot;:
+it means that a specific input, or part of an input (like a tcp listener) will use a specific
+ruleset to &quot;pass its messages to&quot;. So when a new message arrives, it will be processed
+via the bound ruleset. Rule from all other rulesets are irrelevant and will never be processed.
+<p>This makes multiple rulesets very handy to process local and remote message via
+seperate means: bind the respective receivers to different rule sets, and you do not need
+to seperate the messages by any other method.
+
+<p>Binding to rulesets is input-specifc. For imtcp, this is done via the
+
+<pre>$InputTCPServerBindRuleset &lt;name&gt;
+</pre>
+
+directive. Note that &quot;name&quote; must be the name of a ruleset that is already defined
+at the time the bind directive is given. There are many ways to make sure this happens, but
+I personally think that it is best to define all rule sets at the top of rsyslog.conf and
+define the inputs at the bottom. This kind of reverses the traditional recommended ordering, but
+seems to be a really useful and straightforward way of doing things.
+<h2>Can I use a different Ruleset as the default?</h2>
+<p>This is possible by using the
+
+<pre>$DefaultRuleset &lt;name&gt;
+</pre>
+
+Directive. Please note, however, that this directive is actually global: that is, it does not
+modify the ruleset to which the next input is bound but rather provides a system-wide
+default rule set for those inputs that did not explicitly bind to one. As such, the directive
+can not be used as a work-around to bind inputs to non-default rulesets that do not support
+ruleset binding.
+<h2>Examples</h2>
+<h3>Split local and remote logging</h3>
+<p>Let's say you have a pretty standard system that logs its local messages to the usual
+bunch of files that are specified in the default rsyslog.conf. As an example, your rsyslog.conf
+might look like this:
+
+<pre>
+# ... module loading ...
+# The authpriv file has restricted access.
+authpriv.* /var/log/secure
+# Log all the mail messages in one place.
+mail.* /var/log/maillog
+# Log cron stuff
+cron.* /var/log/cron
+# Everybody gets emergency messages
+*.emerg *
+... more ...
+</pre>
+
+<p>Now, you want to add receive messages from a remote system and log these to
+a special file, but you do not want to have these messages written to the files
+specified above. The traditional approach is to add a rule in front of all others that
+filters on the message, processes it and then discards it:
+
+<pre>
+# ... module loading ...
+# process remote messages
+:fromhost-ip, isequal, "192.0.2.1" /var/log/remotefile
+& ~
+# only messages not from 192.0.21 make it past this point
+
+# The authpriv file has restricted access.
+authpriv.* /var/log/secure
+# Log all the mail messages in one place.
+mail.* /var/log/maillog
+# Log cron stuff
+cron.* /var/log/cron
+# Everybody gets emergency messages
+*.emerg *
+... more ...
+</pre>
+
+<p>Note the tilde character, which is the discard action!. Also note that we assume that
+192.0.2.1 is the sole remote sender (to keep it simple).
+
+<p>With multiple rulesets, we can simply define a dedicated ruleset for the remote reception
+case and bind it to the receiver. This may be written as follows:
+
+<pre>
+# ... module loading ...
+# process remote messages
+# define new ruleset and add rules to it:
+$RuleSet remote
+*.* /var/log/remotefile
+# only messages not from 192.0.21 make it past this point
+
+# bind ruleset to tcp listener
+$InputTCPServerBindRuleset remote
+# and activate it:
+$InputTCPServerRun 10514
+
+# switch back to the default ruleset:
+$RuleSet RSYSLOG_DefaultRuleset
+# The authpriv file has restricted access.
+authpriv.* /var/log/secure
+# Log all the mail messages in one place.
+mail.* /var/log/maillog
+# Log cron stuff
+cron.* /var/log/cron
+# Everybody gets emergency messages
+*.emerg *
+... more ...
+</pre>
+
+<p>Here, we need to switch back to the default ruleset after we have defined our custom
+one. This is why I recommend a different ordering, which I find more intuitive. The sample
+below has it, and it leads to the same results:
+
+<pre>
+# ... module loading ...
+# at first, this is a copy of the unmodified rsyslog.conf
+# The authpriv file has restricted access.
+authpriv.* /var/log/secure
+# Log all the mail messages in one place.
+mail.* /var/log/maillog
+# Log cron stuff
+cron.* /var/log/cron
+# Everybody gets emergency messages
+*.emerg *
+... more ...
+# end of the "regular" rsyslog.conf. Now come the new definitions:
+
+# process remote messages
+# define new ruleset and add rules to it:
+$RuleSet remote
+*.* /var/log/remotefile
+
+# bind ruleset to tcp listener
+$InputTCPServerBindRuleset remote
+# and activate it:
+$InputTCPServerRun 10514
+</pre>
+
+<p>Here, we do not switch back to the default ruleset, because this is not needed as it is
+completely defined when we begin the &quot;remote&quot; ruleset.
+
+<p>Now look at the examples and compare them to the single-ruleset solution. You will notice
+that we do <b>not</b> need a real filter in the multi-ruleset case: we can simply use
+&quot;*.*&quot; as all messages now means all messages that are being processed by this
+rule set and all of them come in via the TCP receiver! This is what makes using multiple
+rulesets so much easier.
+
+<h3>Split local and remote logging for three different ports</h3>
+<p>This example is almost like the first one, but it extends it a little bit. While it is
+very similar, I hope it is different enough to provide a useful example why you may want
+to have more than two rulesets.
+
+<p>Again, we would like to use the &quot;regular&quot; log files for local logging, only. But
+this time we set up three syslog/tcp listeners, each one listening to a different
+port (in this example 10514, 10515, and 10516). Logs received from these receivers shall go into
+different files. Also, logs received from 10516 (and only from that port!) with
+&quot;mail.*&quot; priority, shall be written into a specif file and <b>not</b> be
+written to 10516's general log file.
+
+<p>This is the config:
+
+<pre>
+# ... module loading ...
+# at first, this is a copy of the unmodified rsyslog.conf
+# The authpriv file has restricted access.
+authpriv.* /var/log/secure
+# Log all the mail messages in one place.
+mail.* /var/log/maillog
+# Log cron stuff
+cron.* /var/log/cron
+# Everybody gets emergency messages
+*.emerg *
+... more ...
+# end of the "regular" rsyslog.conf. Now come the new definitions:
+
+# process remote messages
+
+#define rulesets first
+$RuleSet remote10514
+*.* /var/log/remote10514
+
+$RuleSet remote10515
+*.* /var/log/remote10515
+
+$RuleSet remote10516
+mail.* /var/log/mail10516
+& ~
+# note that the discard-action will prevent this messag from
+# being written to the remote10516 file - as usual...
+*.* /var/log/remote10516
+
+# and now define listners bound to the relevant ruleset
+$InputTCPServerBindRuleset remote10514
+$InputTCPServerRun 10514
+
+$InputTCPServerBindRuleset remote10515
+$InputTCPServerRun 10515
+
+$InputTCPServerBindRuleset remote10516
+$InputTCPServerRun 10516
+</pre>
+
+<p>Note that the &quot;mail.*&quot; rule inside the &quot;remote10516&quote; ruleset does
+not affect processing inside any other rule set, including the default rule set.
+
+
+<h2>Performance</h2>
+<p>No rule processing can be faster than not processing a rule at all. As such, it is useful
+for a high performance system to identify disjunct actions and try to split these off to
+different rule sets. In the example section, we had a case where three different tcp listeners
+need to write to three different files. This is a perfect example of where multiple rule sets
+are easier to use and offer more performance. The performance is better simply because there
+is no need to check the reception service - instead messages are automatically pushed to the
+right rule set and can be processed by very simple rules (maybe even with
+&quot;*.*&quot;-filters, the fastest ones available).
+
+<p>In the long term, multiple rule sets will probably lay the foundation for even better
+optimizations. So it is not a bad idea to get aquainted with them.

+<h1>Compatibility Notes for rsyslog v4</h1>
+<p><small><i>Written by <a href="http://www.gerhards.net/rainer">Rainer Gerhards</a>
+(2009-07-15)</i></small></p>
+<p>The changes introduced in rsyslog v4 are numerous, but not very intrusive.
+This document describes things to keep in mind when moving from v3 to v4. It
+does not list enhancements nor does it talk about compatibility concerns introduced
+by v3 (for this, see the <a href="v3compatibility.html">rsyslog v3 compatibility notes</a>).
+<h2>HUP processing</h2>
+<p>With v3 and below, rsyslog used the traditional HUP behaviour. That meant that
+all output files are closed and the configuration file is re-read and the new configuration
+applied.
+<p>With a program as simple and static as sysklogd, this was not much of an issue. The
+most important config settings (like udp reception) of a traditional syslogd can not be
+modified via the configuration file. So a config file reload only meant setting up a new set of filters. It also didn't account as problem that while doing so messages may be lost - without
+any threading and queuing model, a traditional syslogd will potentially always loose
+messages, so it is irrelevant if this happens, too, during the short config re-read
+phase.
+<p>In rsyslog, things are quite different: the program is more or less a framework into
+which loadable modules are loaded as needed for a particular configuration. The software
+that will acutally be running is taylored via the config file. Thus, a re-read of
+the config file requires a full, very heavy restart, because the software acutally
+running with the new config can be totally different from what ran with the old config.
+<p>Consequently, the traditional HUP is a very heavy operation and may even cause some
+data loss because queues must be shut down, listeners stopped and so on. Some of these
+operations (depending on their configuration) involve intentional message loss. The operation
+also takes up a lot of system resources and needs quite some time (maybe seconds) to be
+completed. During this restart period, the syslog subsytem is not fully available.
+<p>From the software developer's point of view, the full restart done by a HUP is rather complex,
+especially if user-timeout limits set on action completion are taken into consideration (for
+those in the know: at the extreme ends this means we need to cancel threads as a last resort,
+but than we need to make sure that such cancellation does not happen at points where it
+would be fatal for a restart). A regular restart, where the process is actually terminated, is
+much less complex, because the operating system does a full cleanup after process termination,
+so rsyslogd does not need to take care for exotic cleanup cases and leave that to the OS.
+In the end result, restart-type HUPs clutter the code, increase complexity (read: add bugs)
+and cost performance.
+<p>On the contrary, a HUP is typically needed for log rotation, and the real desire is
+to close files. This is a non-disruptive and very lightweigth operation.
+<p>Many people have said that they are used to HUP the syslogd to apply configuration
+changes. This is true, but it is questionable if that really justifies all the cost that
+comes with it. After all, it is the difference between typing
+<pre>
+$ kill -HUP `cat /var/run/rsyslogd.pid`
+</pre>
+versus
+<pre>
+$ /etc/init.d/rsyslog restart
+</pre>
+Semantically, both is mostly the same thing. The only difference is that with the restart
+command rsyslogd can spit config error message to stderr, so that the user is able to see
+any problems and fix them. With a HUP, we do not have access to stderr and thus can log
+error messages only to their configured destinations; exprience tells that most users
+will never find them there. What, by the way, is another strong argument against
+restarting rsyslogd by HUPing it.
+<p>So a restart via HUP is not strictly necessary
+and most other deamons require that a restart command is typed in if a restart is required.
+<p>Rsyslog will follow this paradigm in the next versions, resulting in many benefits. In v4,
+we provide some support for the old-style semantics. We introduced a setting $HUPisRestart
+which may be set to &quot;on&quot; (tradional, heavy operationg)
+or &quot;off&quot; (new, lightweight &quot;file close only&quot; operation).
+The initial versions had the default set to traditional behavior, but starting with 4.5.1
+we are now using the new behavior as the default.
+<p>Most importantly, <b>this may break some scripts</b>, but my sincere belief is that
+there are very few scripts that automatically <b>change</b> rsyslog's config and then do a
+HUP to reload it. Anyhow, if you have some of these, it may be a good idea to change
+them now instead of turning restart-type HUPs on. Other than that, one mainly needs
+to change the habit of how to restart rsyslog after a configuration change.
+<p><b>Please note that restart-type HUP is depricated and will go away in rsyslog v5.</b>
+So it is a good idea to become ready for the new version now and also enjoy some of the
+benefits of the &quot;real restart&quot;, like the better error-reporting capability.
+<p>Note that code complexity reduction (and thus performance improvement) needs the restart-type
+HUP code to be removed, so these changes can (and will) only happen in version 5.

+ * an extended period of time, as this either causes message loss or - even worse - some
+ * other bad effects (e.g. unresponsive system in respect to the main system log socket).
+ * Finally, there are some (few) sources which can not be blocked at all. UDP syslog is
+ * a prime example. If a UDP message is not received, it is simply lost. So we can't
+ * do anything against UDP sockets that come in too fast. The core idea of advanced
+ * flow control is that we take into account the different natures of the sources and
