+Version 3.19.12 [BETA] (rgerhards), 2008-08-25
+---------------------------------------------------------------------------
+Version 3.19.11 [BETA] (rgerhards), 2008-08-25
+This is a refresh of the beta. No beta-specific fixes have been added.
+- included fixes from v3-stable (most importantly 3.18.3)
+---------------------------------------------------------------------------
+Version 3.19.10 [BETA] (rgerhards), 2008-07-15
+- start of a new beta branch based on former 3.19 devel branch
+- bugfix: bad memory leak in disk-based queue modes
+- bugfix: UDP syslog forwarding did not work on all platforms
+  the ai_socktype was incorrectly set to 1. On some platforms, this
+  lead to failing name resolution (e.g. FreeBSD 7). Thanks to HKS for
+  reporting the bug.
+- bugfix: priority was incorrectly calculated on FreeBSD 7,
+  because the LOG_MAKEPRI() C macro has a different meaning there (it
+  is just a simple addition of faciltity and severity). I have changed
+  this to use own, consistent, code for PRI calculation. Thank to HKS
+  for reporting this bug.
+- bugfix (cosmetical): authorization was not checked when gtls handshake
+  completed immediately. While this sounds scary, the situation can not
+  happen in practice. We use non-blocking IO only for server-based gtls
+  session setup. As TLS requires the exchange of multiple frames before
+  the handshake completes, it simply is impossible to do this in one
+  step. However, it is useful to have the code path correct even for 
+  this case - otherwise, we may run into problems if the code is changed
+  some time later (e.g. to use blocking sockets). Thanks to varmojfekoj
+  for providing the patch.
+- important queue bugfix from 3.18.1 imported (see below)
+- cleanup of some debug messages
+---------------------------------------------------------------------------
+Version 3.19.9 (rgerhards), 2008-07-07
+- added tutorial for creating a TLS-secured syslog infrastructure
+- rewritten omusrmsg to no longer fork() a new process for sending messages
+  this caused some problems with the threading model, e.g. zombies. Also,
+  it was far less optimal than it is now.
+- bugfix: machine certificate was required for client even in TLS anon mode
+  Reference: http://bugzilla.adiscon.com/show_bug.cgi?id=85
+  The fix also slightly improves performance by not storing certificates in
+  client sessions when there is no need to do so.
+- bugfix: RainerScript syntax error was not always detected
+---------------------------------------------------------------------------
+Version 3.19.8 (rgerhards), 2008-07-01
+- bugfix: gtls module did not correctly handle EGAIN (and similar) recv()
+  states. This has been fixed by introducing a new abstraction layer inside
+  gtls.
+- added (internal) error codes to error messages; added redirector to
+  web description of error codes
+  closes bug http://bugzilla.adiscon.com/show_bug.cgi?id=20
+- disabled compile warnings caused by third-party libraries
+- reduced number of compile warnings in gcc's -pedantic mode
+- some minor documentation improvements
+- included all fixes from beta 3.17.5
+---------------------------------------------------------------------------
+Version 3.19.7 (rgerhards), 2008-06-11
+- added new property replacer option "date-subseconds" that enables
+  to query just the subsecond part of a high-precision timestamp
+- somewhat improved plain tcp syslog reliability by doing a connection
+  check before sending. Credits to Martin Schuette for providing the
+  idea. Details are available at
+  http://blog.gerhards.net/2008/06/reliable-plain-tcp-syslog-once-again.html
+- made rsyslog tickless in the (usual and default) case that repeated
+  message reduction is turned off. More info:
+  http://blog.gerhards.net/2008/06/coding-to-save-environment.html
+- some build system cleanup, thanks to Michael Biebl
+- bugfix: compile under (Free)BSD failed due to some invalid library
+  definitions - this is fixed now. Thanks to Michael Biebl for the patch.
+---------------------------------------------------------------------------
+Version 3.19.6 (rgerhards), 2008-06-06
+- enhanced property replacer to support multiple regex matches
+- bugfix: part of permittedPeer structure was not correctly initialized
+  thanks to varmojfekoj for spotting this
+- bugfix: off-by-one bug during certificate check
+- bugfix: removed some memory leaks in TLS code
+---------------------------------------------------------------------------
+Version 3.19.5 (rgerhards), 2008-05-30
+- enabled Posix ERE expressions inside the property replacer
+  (previously BRE was permitted only)
+- provided ability to specify that a regular expression submatch shall
+  be used inside the property replacer
+- implemented in property replacer: if a regular expression does not match,
+  it can now either return "**NO MATCH** (default, as before), a blank
+  property or the full original property text
+- enhanced property replacer to support multiple regex matches
+---------------------------------------------------------------------------
+Version 3.19.4 (rgerhards), 2008-05-27
+- implemented x509/certvalid gtls auth mode
+- implemented x509/name gtls auth mode (including wildcards)
+- changed fingerprint gtls auth mode to new format fingerprint
+- protected gtls error string function by a mutex. Without it, we
+  could have a race condition in extreme cases. This was very remote,
+  but now can no longer happen.
+- changed config directive name to reflect different use
+  $ActionSendStreamDriverCertFingerprint is now
+  $ActionSendStreamDriverPermittedPeer and can be used both for
+  fingerprint and name authentication (similar to the input side)
+- bugfix: sender information (fromhost et al) was missing in imudp
+  thanks to sandiso for reporting this bug
+- this release fully inplements IETF's syslog-transport-tls-12 plus
+  the latest text changes Joe Salowey provided via email. Not included
+  is ipAddress subjectAltName authentication, which I think will be
+  dropped from the draft. I don't think there is any real need for it.
+This release also includes all bug fix up to today from the beta
+and stable branches. Most importantly, this means the bugfix for
+100% CPU utilization by imklog.
+---------------------------------------------------------------------------
+Version 3.19.3 (rgerhards), 2008-05-21
+- added ability to authenticate the server against its certificate
+  fingerprint
+- added ability for client to provide its fingerprint
+- added ability for server to obtain client cert's fingerprint
+- bugfix: small mem leak in omfwd on exit (strmdriver name was not freed)
+- bugfix: $ActionSendStreamDriver had no effect
+- bugfix: default syslog port was no longer used if none was
+  configured. Thanks to varmojfekoj for the patch
+- bugfix: missing linker options caused build to fail on some
+  systems. Thanks to Tiziano Mueller for the patch.
+---------------------------------------------------------------------------
+Version 3.19.2 (rgerhards), 2008-05-16
+- bugfix: TCP input modules did incorrectly set fromhost property
+  (always blank)
+- bugfix: imklog did not set fromhost property
+- added "fromhost-ip" property
+  Note that adding this property changes the on-disk format for messages.
+  However, that should not have any bad effect on existing spool files.
+  But you will run into trouble if you create a spool file with this
+  version and then try to process it with an older one (after a downgrade).
+  Don't do that ;)
+- added "RSYSLOG_DebugFormat" canned template
+- bugfix: hostname and fromhost were swapped when a persisted message
+  (in queued mode) was read in
+- bugfix: lmtcpclt, lmtcpsrv and lmgssutil did all link to the static
+  runtime library, resulting in a large size increase (and potential
+  "interesting" effects). Thanks to Michael Biebel for reporting the size
+  issue.
+- bugfix: TLS server went into an endless loop in some situations.
+  Thanks to Michael Biebl for reporting the problem.
+- fixed potential segfault due to invalid call to cfsysline
+  thanks to varmojfekoj for the patch
+---------------------------------------------------------------------------
+Version 3.19.1 (rgerhards), 2008-05-07
+- configure help for --enable-gnutls wrong - said default is "yes" but
+  default actually is "no" - thanks to darix for pointing this out
+- file dirty.h was missing - thanks to darix for pointing this out
+- bugfix: man files were not properly distributed - thanks to
+  darix for reporting and to Michael Biebl for help with the fix
+- some minor cleanup
+---------------------------------------------------------------------------
+Version 3.19.0 (rgerhards), 2008-05-06
+- begins new devel branch version
+- implemented TLS for plain tcp syslog (this is also the world's first
+  implementation of IETF's upcoming syslog-transport-tls draft)
+- partly rewritten and improved omfwd among others, now loads TCP
+  code only if this is actually necessary
+- split of a "runtime library" for rsyslog - this is not yet a clean
+  model, because some modularization is still outstanding. In theory,
+  this shall enable other utilities but rsyslogd to use the same
+  runtime
+- implemented im3195, the RFC3195 input as a plugin
+- changed directory structure, files are now better organized
+- a lot of cleanup in regard to modularization
+- -c option no longer must be the first option - thanks to varmjofekoj
+  for the patch
+---------------------------------------------------------------------------
 Version 3.18.5 (rgerhards), 2008-10-??
 - added doc on malformed messages, cause and how to work-around, to the
   doc set

+<h1>RFC3195 Input Module</h1>
+<p><b>Module Name:&nbsp;&nbsp;&nbsp; im3195</b></p>
+<p><b>Author: </b>Rainer Gerhards
+&lt;rgerhards@adiscon.com&gt;</p>
+<p><b>Description</b>:</p>
+<p>Receives syslog messages via RFC 3195. The RAW profile is fully implemented and the 
+COOKED profile is provided in an experimental state. This module uses
+<a href="http://www.liblogging.org">liblogging</a> for the actual protocol handling.</p>
+<p><b>Configuration Directives</b>:</p>
+<ul>
+<li><strong>$Input3195ListenPort &lt;port&gt;</strong><br>
+The port on which imklog listens for RFC 3195 messages. The default port is 601
+(the IANA-assigned port)</li>
+</ul>
+<b>Caveats/Known Bugs:</b>
+<p>Due to no demand at all for RFC3195, we have converted rfc3195d
+to this input module, but we have NOT conducted any testing. Also,
+the module does not yet properly handle the recovery case. If someone
+intends to put this module into production, good testing should be
+cunducted. It also is a good idea to notify the rsyslog project that you intend to use
+it in production. In this case, we'll probably give the module another
+cleanup. We don't do this now because so far it looks just like a big
+waste of time.
+<p>Currently only a single listener can be defined. That one binds to all interfaces.</p>
+<p><b>Sample:</b></p>
+<p>The following sample accepts syslog messages via RFC 3195 on port 1601.

+Note: "anon" does not permit to authenticate the remote peer. As such,
+this mode is vulnerable to man in the middle attacks as well as
+unauthorized access. It is recommended NOT to use this mode.</p>
+<p>x509/certvalid is a nonstandard mode. It validates the remote
+peers certificate, but does not check the subject name. This is 
+weak authentication that may be useful in scenarios where multiple
+devices are deployed and it is sufficient proof of authenticy when
+their certificates are signed by the CA the server trusts. This is
+better than anon authentication, but still not recommended.
+<b>Known Problems</b><br>
+<p>Even in x509/fingerprint mode, both the client and sever
+certificate currently must be signed by the same root CA. This is an
+artifact of the underlying GnuTLS library and the way we use it. It is
+expected that we can resolve this issue in the future.</p>

+<p>Please note that custom development is not limited to rsyslog. We offer
+a number of logging solutions and can also work as part of your time

+solutions. We sweat logging for over 15 years now and can help quickly.
+Depending on your needs, consulting can be carried out via email, the
+phone or on your premises (for larger or local projects). Everything is
+possible, it just depends on your needs. Consulting services are

+<p>regexp-type is either "BRE" for Posix basic regular expressions or
+"ERE" for extended ones. The string must be given in upper case. The
+default is "BRE" to be consistent with earlier versions of rsyslog that
+did not support ERE. The submatch identifies the submatch to be used
+with the result. A single digit is supported. Match 0 is the full match,
+while 1 to 9 are the acutal submatches. The match-number identifies which match to
+use, if the expression occurs more than once inside the string. Please note
+that the first match is number 0, the second 1 and so on. Up to 10 matches
+(up to number 9) are supported. Please note that it would be more
+natural to have the match-number in front of submatch, but this would break 
+backward-compatibility. So the match-number must be specified after "nomatch".
+<p>nomatch is either "DFLT", "BLANK" or "FIELD" (all upper case!). It tells
+what to use if no match is found. With "DFLT", the strig "**NO MATCH**" is
+used. This was the only supported value up to rsyslog 3.19.5. With "BLANK"
+a blank text is used (""). Finally, "FIELD" uses the full property text
+instead of the expression. Some folks have requested that, so it seems
+to be useful.

+submatch from the message string and replaces the expression with

+
+<h2>Overview</h2>
+<p>This document describes a secure way to set up rsyslog TLS. A secure logging
+environment requires more than just encrypting the transmission channel. This document
+provides one possible way to create such a secure system.
+<p>Rsyslog's TLS authentication can be used very flexible and thus supports a 
+wide range of security policies. This section tries to give some advise on a 
+scenario that works well for many environments. However, it may not be suitable 
+for you - please assess you security needs before using the recommendations 
+below. Do not blame us if it doesn't provide what you need ;)</p>
+<p>Our policy offers these security benefits:</p>
+<ul>
+	<li>syslog messages are encrypted while traveling on the wire</li>
+	<li>the syslog sender authenticates to the syslog receiver; thus, the 
+	receiver knows who is talking to it</li>
+	<li>the syslog receiver authenticates to the syslog sender; thus, the sender 
+	can check if it indeed is sending to the expected receiver</li>
+	<li>the mutual authentication prevents man-in-the-middle attacks</li>
+</ul>
+<p>Our secrity goals are achived via public/private key security. As such, it is 
+vital that private keys are well protected and not accessible to third parties. 
+<span style="float: left">
+<script type="text/javascript"><!--
+google_ad_client = "pub-3204610807458280";

+</script>
+</span>
+I private keys have become known to third parties, the system does not provide 
+any security at all. Also, our solution bases on X.509 certificates and a (very 
+limited) chain of trust. We have one instance (the CA) that issues all machine 
+certificates. The machine certificate indentifies a particular machine. hile in 
+theory (and practice), there could be several &quot;sub-CA&quot; that issues machine 
+certificates for a specific adminitrative domain, we do not include this in our 
+&quot;simple yet secure&quot; setup. If you intend to use this, rsyslog supports it, but 
+then you need to dig a bit more into the documentation (or use the forum to ask). 
+In general, if you depart from our simple model, you should have good reasons 
+for doing so and know quite well what you are doing - otherwise you may 
+compromise your system security.</p>
+<p>Please note that security never comes without effort. In the scenario 
+described here, we have limited the effort as much as possible. What remains is 
+some setup work for the central CA, the certificate setup for each machine as 
+well as a few configuration commands that need to be applied to all of them. 
+Proably the most important limiting factor in our setup is that all senders and 
+receivers must support IETF's syslog-transport-tls standard (which is not 
+finalized yet). We use mandatory-to-implement technology, yet you may have 
+trouble finding all required features in some implementations. More often, 
+unfortunately, you will find that an implementation does not support the 
+upcoming IETF standard at all - especially in the &quot;early days&quot; (starting May 
+2008) when rsyslog is the only implementation of said standard.</p>
+<p>Fortunately, rsyslog supports allmost every protocol that is out there in the 
+syslog world. So in cases where transport-tls is not available on a sender, we 
+recommend to use rsyslog as the initial relay. In that mode, the not-capabe 
+sender sends to rsyslog via another protocol, which then relays the message via 
+transport-tls to either another interim relay or the final destination (which, 
+of course, must by transport-tls capable). In such a scenario, it is best to try 
+see what the sender support. Maybe it is possible to use industry-standard plain 
+tcp syslog with it. Often you can even combine it with stunnel, which then, too, 
+enables a secure delivery to the first rsyslog relay. If all of that is not 
+possible, you can (and often must...) resort to UDP. Even though this is now 
+lossy and insecure, this is better than not having the ability to listen to that 
+device at all. It may even be reasonale secure if the uncapable sender and the 
+first rsyslog relay communicate via a private channel, e.g. a dedicated network 
+link.</p>
+<p>One final word of caution: transport-tls protects the connection between the 
+sender and the receiver. It does not necessarily protect against attacks that 
+are present in the message itself. Especially in a relay environment, the 
+message may have been originated from a malicious system, which placed invalid 
+hostnames and/or other content into it. If there is no provisioning against such 
+things, these records may show up in the receivers' repository. -transport-tls 
+does not protect against this (but it may help, properly used). Keep in mind 
+that syslog-transport-tls provides hop-by-hop security. It does not provide 
+end-to-end security and it does not authenticate the message itself (just the 
+last sender).</p>

-<h1>SSL Encrypting Syslog with Stunnel</h1>

-		<P><small><i>Written by

-		<a href="http://www.adiscon.com/en/people/rainer-gerhards.php">Rainer 

-		Gerhards</a> (2005-07-22)</i></small></P>

-<h2>Abstract</h2>

-<p><i><b>In this paper, I describe how to encrypt <a href="http://www.monitorware.com/en/topics/syslog/">syslog</a>

-messages on the network.</b> Encryption

-is vital to keep the confidiental content of syslog messages secure. I describe the overall

-approach and provide an HOWTO do it with the help of 

-<a href="http://www.rsyslog.com">rsyslogd</a> and <a href="http://www.stunnel.org">stunnel</a>.</i></p>

-<h2>Background</h2>

-<P><b>Syslog is a 

-clear-text protocol. That means anyone with a sniffer can have 

-a peek at your data.</b> In some environments, this is no problem at all. In 

-others, it is a huge setback, probably even preventing deployment of syslog 

-solutions. Thankfully, there is an easy way to encrypt syslog communication. I 

-will describe one approach in this paper.</P>

-<P>The most straigthforward solution would be that the syslogd itself encrypts 

-messages. Unfortuantely, encryption is only standardized in

-<a href="http://www.monitorware.com/Common/en/glossary/rfc3195.php">RFC 3195</a>. But there 

-is currently no syslogd that implements RFC 3195's encryption features, 

-so this route leads to nothing. Another approach would be to use vendor- or 

-project-specific syslog extensions. There are a few around, but the problem here 

-is that they have compatibility issues. However, there is one surprisingly easy 

-and interoperable solution: though not standardized, many vendors and projects 

-implement plain tcp syslog. In a nutshell, plain tcp syslog is a mode where 

-standard syslog messages are transmitted via tcp and records are separated by 

-newline characters. This mode is supported by all major syslogd's (both on Linux/Unix 

-and Windows) as well as log sources (for example,

-<a href="http://www.eventreporter.com/en/">EventReporter</a> for Windows 

-Event Log forwarding). Plain tcp syslog offers reliability, but it does not 

-offer encryption in itself. However, since it operates on a tcp stream, it is now easy 

-to add encryption. There are various ways to do that. In this paper, I will 

-describe how it is done with stunnel (an

-other alternative would be <a href="http://en.wikipedia.org/wiki/IPSec">IPSec</a>, for example).</P>

-<P>Stunnel is open source and it is available both for Unix/Linux and Windows. 

-It provides a way to 

-			use ssl communication for any non-ssl aware client and server - in this case,

-		our syslogd.</P>

-		<P>Stunnel works much like a wrapper. Both on the client and on the server machine, 

-			tunnel portals are created. The non-ssl aware client and server software is 

-			configured to not directly talk to the remote partner, but to the local 

-			(s)tunnel portal instead. Stunnel, in turn, takes the data received from the 

-			client, encrypts it via ssl, sends it to the remote tunnel portal and that 

-			remote portal sends it to the recipient process on the remote machine. The 

-			transfer to the portals is done via unencrypted communication. As such, 

-			it is vital that 

-			the portal and the respective program that is talking to it are on the same 

-			machine, otherwise data would travel partly unencrypted. Tunneling, as done by stunnel, 

-		requires connection oriented communication. This is why you need to use 

-		tcp-based syslog. As a side-note, you can also encrypt a plain-text RFC 

-		3195 session via stunnel, though this definitely is not what the 

-		protocol designers had on their mind ;)</P>

-<P>In the rest of this document, I assume that you use rsyslog on both the 

-client and the server. For the samples, I use <a href="http://www.debian.org/">Debian</a>.

-Interestingly, there are 

-some annoying differences between stunnel implementations. For example, on 

-Debian a comment line starts with a semicolon (';'). On 

-<a href="http://www.redhat.com">Red Hat</a>, it starts with 

-a hash sign ('#'). So you need to watch out for subtle issues when setting up 

-your system.</P>

-<h2>Overall System Setup</h2>

-<P>In ths paper, I assume two machines, one named &quot;client&quot; and the other named &quot;server&quot;. 

-It is obvious that, in practice, you will probably have multiple clients but 

-only one server. Syslog traffic shall be transmitted via stunnel over the 

-network. Port 60514 is to be used for that purpose. The machines are set up as 

-follows:</P>

-<P><b>Client</b></P>

-<ul>

-	<li>rsyslog forwards&nbsp; message to stunnel local portal at port 61514</li>

-	<li>local stunnel forwards data via the network to port 60514 to its remote 

-	peer</li>

-</ul>

-<P><b>Server</b></P>

-<ul>

-	<li>stunnel listens on port 60514 to connections from its client peers</li>

-	<li>all connections are forwarded to the locally-running rsyslog listening 

-	at port 61514</li>

-</ul>

-<h2>Setting up the system</h2>

-<P>For Debian, you need the &quot;stunnel4&quot; package. The &quot;stunnel&quot; package is the 

-older 3.x release, which will not support the configuration I describe below. 

-Other distributions might have other names. For example, on Red Hat it is just &quot;stunnel&quot;. 

-Make sure that you install the appropriate package on both the client and the 

-server. It is also a good idea to check if there are updates for either stunnel 

-or openssl (which stunnel uses) - there are often security fixes available and 

-often the latest fixes are not included in the default package.</P>

-<P>In my sample setup, I use only the bare minimum of options. For example, I do 

-not make the server check client cerficiates. Also, I do not talk much about 

-certificates at all. If you intend to really secure your system, you should 

-probably learn about certificates and how to manage and deploy them. This is 

-beyond the scope of this paper. For additional information,

-<a href="http://www.stunnel.org/faq/certs.html">

-http://www.stunnel.org/faq/certs.html</a> is a good starting point.</P>

-<P>You also need to install rsyslogd on both machines. Do this before starting 

-with the configuration. You should also familarize yourself with its 

-configuration file syntax, so that you know which actions you can trigger with 

-it. Rsyslogd can work as a drop-in replacement for stock

-<a href="http://www.infodrom.org/projects/sysklogd/">sysklogd</a>. So if you know 

-the standard syslog.conf syntax, you do not need to learn any more to follow 

-this paper.</P>

-<h3>Server Setup</h3>

-<P>At the server, you need to have a digital certificate. That certificate 

-enables SSL operation, as it provides the necessary crypto keys being used to 

-secure the connection. Many versions of stunnel come with a default certificate, 

-often found in /etc/stunnel/stunnel.pem. If you have it, it is good for testing 

-only. If you use it in production, it is very easy to break into your secure 

-channel as everybody is able to get hold of your private key. I didn't find an 

-stunnel.pem on my Debian machine. I guess the Debian folks removed it because of 

-its insecurity.</P>

-<P>You can create your own certificate with a simple openssl tool - you need to 

-do it if you have none and I highly recommend to create one in any case. To 

-create it, cd to /etc/stunnel and type:</P>

-<p><blockquote><code>openssl req -new -x509 -days 3650 -nodes -out 

-stunnel.pem -keyout stunnel.pem</code></blockquote></p>

-<P>That command will ask you a number of questions. Provide some answer for 

-them. If you are unsure, read

-<a href="http://www.stunnel.org/faq/certs.html">

-http://www.stunnel.org/faq/certs.html</a>. After the command has finished, you 

-should have a usable stunnel.pem in your working directory.</P>

-<P>Next is to create a configuration file for stunnel. It will direct stunnel 

-what to do. You can used the following basic file:</P>

-<P><blockquote><code><pre>; Certificate/key is needed in server mode

-cert = /etc/stunnel/stunnel.pem

-

-<i>; Some debugging stuff useful for troubleshooting

-debug = 7

-foreground=yes</i>

-

-[ssyslog]

-accept  = 60514

-connect = 61514</pre>

-</code></blockquote></P>

-<p>Save this file to e.g. /etc/stunnel/syslog-server.conf. Please note that the 

-settings in <i>italics</i> are for debugging only. They run stunnel 

-with a lot of debug information in the foreground. This is very valuable while 

-you setup the system - and very useless once everything works well. So be sure 

-to remove these lines when going to production.</p>

-<p>Finally, you need to start the stunnel daemon. Under Debian, this is done via 

-&quot;stunnel /etc/stunnel/syslog.server.conf&quot;. If you have enabled the debug 

-settings, you will immediately see a lot of nice messages.</p>

-<p>Now you have stunnel running, but it obviously unable to talk to rsyslog - 

-because it is not yet running. If not already done, configure it so that it does 

-everything you want. If in doubt, you can simply copy /etc/syslog.conf to /etc/rsyslog.conf 

-and you probably have what you want. The really important thing in rsyslogd 

-configuration is that you must make it listen to tcp port 61514 (remember: this 

-is where stunnel send the messages to). Thankfully, this is easy to achive: just 

-add &quot;-t 61514&quot; to the rsyslogd startup options in your system startup script. 

-After done so, start (or restart) rsyslogd.</p>

-<p>The server should now be fully operational.</p>

-<h3>Client Setup</h3>

-<P>The client setup is simpler. Most importantly, you do not need a certificate 

-(of course, you can use one if you would like to authenticate the client, but 

-this is beyond the scope of this paper). So the basic thing you need to do is 

-create the stunnel configuration file.</P>

-<P><blockquote><code><pre><i>; Some debugging stuff useful for troubleshooting

-debug = 7

-foreground=yes</i>

-

-<b>client=yes</b>

-

-[ssyslog]

-accept  = 127.0.0.1:61514

-connect = <font color="#FF0000">192.0.2.1</font>:60514

-</pre>

-</code></blockquote></P>

-<P>Again, the text in <i>italics</i> is for debugging purposes only. I suggest 

-you leave it in during your initial testing and then remove it. The most 

-important difference to the server configuration outlined above is the &quot;client=yes&quot; 

-directive. It is what makes this stunnel behave like a client. The accept 

-directive binds stunnel only to the local host, so that it is protected from 

-receiving messages from the network (somebody might fake to be the local sender). 

-The address &quot;192.0.2.1&quot; is the address of the server machine. You must change it 

-to match your configuration. Save this file to /etc/stunnel/syslog-client.conf.</P>

-<P>Then, start stunnel via &quot;stunnel4 /etc/stunnel/syslog-client.conf&quot;.&nbsp; Now 

-you should see some startup messages. If no errors appear, you have a running 

-client stunnel instance.</P>

-<P>Finally, you need to tell rsyslogd to send data to the remote host. In stock 

-syslogd, you do this via the &quot;@host&quot; forwarding directive. The same works with 

-rsyslog, but it suppports extensions to use tcp. Add the following line to your 

-/etc/rsyslog.conf:</P>

-<P><blockquote><code><pre>*.*      @<font color="#FF0000">@</font>127.0.0.1:61514

-</pre>

-</code></blockquote><i></P>

-

-</i>

-

-<P>Please note the double at-sign (@@). This is no typo. It tells rsyslog to use 

-tcp instead of udp delivery. In this sample, all messages are forwarded to the 

-remote host. Obviously, you may want to limit this via the usual rsyslog.conf 

-settings (if in doubt, use man rsyslog.con).</P>

-<P>You do not need to add any special startup settings to rsyslog on the client. 

-Start or restart rsyslog so that the new configuration setting takes place.</P>

-<h3>Done</h3>

-<P>After following these steps, you should have a working secure syslog 

-forwarding system. To verify, you can type &quot;logger test&quot; or a similar smart 

-command on the client. It should show up in the respective server log file. If 

-you dig out you sniffer, you should see that the traffic on the wire is actually 

-protected. In the configuration use above, the two stunnel endpoints should be 

-quite chatty, so that you can follow the action going on on your system.</P>

-<P>If you have only basic security needs, you can probably just remove the debug 

-settings and take the rest of the configuration to production. If you are 

-security-sensitve, you should have a look at the various stunnel settings that 

-help you further secure the system.</P>

-<h2>Preventing Systems from talking directly to the rsyslog Server</h2>

-<P>It is possible that remote systems (or attackers) talk to the rsyslog server 

-by directly connecting to its port 61514. Currently (July of 2005), rsyslog does 

-not offer the ability to bind to the local host, only. This feature is planned, 

-but as long as it is missing, rsyslog must be protected via a firewall. This can 

-easily be done via e.g iptables. Just be sure not to forget it.</P>

-<h2>Conclusion</h2>

-<P>With minumal effort, you can set up a secure logging infrastructure employing 

-ssl encrypted syslog message transmission. As a side note, you also have the 

-benefit of reliable tcp delivery which is far less prone to message loss than 

-udp.</P>

+<h2>Background</h2>
+<p><b>Syslog is a 
+clear-text protocol. That means anyone with a sniffer can have 
+a peek at your data.</b> In some environments, this is no problem at all. In 
+others, it is a huge setback, probably even preventing deployment of syslog 
+solutions. Thankfully, there is an easy way to encrypt syslog communication. I 
+will describe one approach in this paper.</p>
+<p>The most straigthforward solution would be that the syslogd itself encrypts 
+messages. Unfortuantely, encryption is only standardized in
+<a href="http://www.monitorware.com/Common/en/glossary/rfc3195.php">RFC 3195</a>. But there 
+is currently no syslogd that implements RFC 3195's encryption features, 
+so this route leads to nothing. Another approach would be to use vendor- or 
+project-specific syslog extensions. There are a few around, but the problem here 
+is that they have compatibility issues. However, there is one surprisingly easy 
+and interoperable solution: though not standardized, many vendors and projects 
+implement plain tcp syslog. In a nutshell, plain tcp syslog is a mode where 
+standard syslog messages are transmitted via tcp and records are separated by 
+newline characters. This mode is supported by all major syslogd's (both on Linux/Unix 
+and Windows) as well as log sources (for example,
+<a href="http://www.eventreporter.com/en/">EventReporter</a> for Windows 
+Event Log forwarding). Plain tcp syslog offers reliability, but it does not 
+offer encryption in itself. However, since it operates on a tcp stream, it is now easy 
+to add encryption. There are various ways to do that. In this paper, I will 
+describe how it is done with stunnel (an
+other alternative would be <a href="http://en.wikipedia.org/wiki/IPSec">IPSec</a>, for example).</p>
+<p>Stunnel is open source and it is available both for Unix/Linux and Windows. 
+It provides a way to 
+			use ssl communication for any non-ssl aware client and server - in this case,
+		our syslogd.</p>
+		<p>Stunnel works much like a wrapper. Both on the client and on the server machine, 
+			tunnel portals are created. The non-ssl aware client and server software is 
+			configured to not directly talk to the remote partner, but to the local 
+			(s)tunnel portal instead. Stunnel, in turn, takes the data received from the 
+			client, encrypts it via ssl, sends it to the remote tunnel portal and that 
+			remote portal sends it to the recipient process on the remote machine. The 
+			transfer to the portals is done via unencrypted communication. As such, 
+			it is vital that 
+			the portal and the respective program that is talking to it are on the same 
+			machine, otherwise data would travel partly unencrypted. Tunneling, as done by stunnel, 
+		requires connection oriented communication. This is why you need to use 
+		tcp-based syslog. As a side-note, you can also encrypt a plain-text RFC 
+		3195 session via stunnel, though this definitely is not what the 
+		protocol designers had on their mind ;)</p>
+<p>In the rest of this document, I assume that you use rsyslog on both the 
+client and the server. For the samples, I use <a href="http://www.debian.org/">Debian</a>.
+Interestingly, there are 
+some annoying differences between stunnel implementations. For example, on 
+Debian a comment line starts with a semicolon (';'). On 
+<a href="http://www.redhat.com">Red Hat</a>, it starts with 
+a hash sign ('#'). So you need to watch out for subtle issues when setting up 
+your system.</p>
+<h2>Overall System Setup</h2>
+<p>In ths paper, I assume two machines, one named "client" and the other named "server". 
+It is obvious that, in practice, you will probably have multiple clients but 
+only one server. Syslog traffic shall be transmitted via stunnel over the 
+network. Port 60514 is to be used for that purpose. The machines are set up as 
+follows:</p>
+<p><b>Client</b></p>
+<ul>
+	<li>rsyslog forwards&nbsp; message to stunnel local portal at port 61514</li>
+	<li>local stunnel forwards data via the network to port 60514 to its remote 
+	peer</li>
+</ul>
+<p><b>Server</b></p>
+<ul>
+	<li>stunnel listens on port 60514 to connections from its client peers</li>
+	<li>all connections are forwarded to the locally-running rsyslog listening 
+	at port 61514</li>
+</ul>
+<h2>Setting up the system</h2>
+<p>For Debian, you need the "stunnel4" package. The "stunnel" package is the 
+older 3.x release, which will not support the configuration I describe below. 
+Other distributions might have other names. For example, on Red Hat it is just "stunnel". 
+Make sure that you install the appropriate package on both the client and the 
+server. It is also a good idea to check if there are updates for either stunnel 
+or openssl (which stunnel uses) - there are often security fixes available and 
+often the latest fixes are not included in the default package.</p>
+<p>In my sample setup, I use only the bare minimum of options. For example, I do 
+not make the server check client cerficiates. Also, I do not talk much about 
+certificates at all. If you intend to really secure your system, you should 
+probably learn about certificates and how to manage and deploy them. This is 
+beyond the scope of this paper. For additional information,
+<a href="http://www.stunnel.org/faq/certs.html">
+http://www.stunnel.org/faq/certs.html</a> is a good starting point.</p>
+<p>You also need to install rsyslogd on both machines. Do this before starting 
+with the configuration. You should also familarize yourself with its 
+configuration file syntax, so that you know which actions you can trigger with 
+it. Rsyslogd can work as a drop-in replacement for stock
+<a href="http://www.infodrom.org/projects/sysklogd/">sysklogd</a>. So if you know 
+the standard syslog.conf syntax, you do not need to learn any more to follow 
+this paper.</p>
+<h3>Server Setup</h3>
+<p>At the server, you need to have a digital certificate. That certificate 
+enables SSL operation, as it provides the necessary crypto keys being used to 
+secure the connection. Many versions of stunnel come with a default certificate, 
+often found in /etc/stunnel/stunnel.pem. If you have it, it is good for testing 
+only. If you use it in production, it is very easy to break into your secure 
+channel as everybody is able to get hold of your private key. I didn't find an 
+stunnel.pem on my Debian machine. I guess the Debian folks removed it because of 
+its insecurity.</p>
+<p>You can create your own certificate with a simple openssl tool - you need to 
+do it if you have none and I highly recommend to create one in any case. To 
+create it, cd to /etc/stunnel and type:</p>
+<p></p><blockquote><code>openssl req -new -x509 -days 3650 -nodes -out 
+stunnel.pem -keyout stunnel.pem</code></blockquote><p></p>
+<p>That command will ask you a number of questions. Provide some answer for 
+them. If you are unsure, read
+<a href="http://www.stunnel.org/faq/certs.html">
+http://www.stunnel.org/faq/certs.html</a>. After the command has finished, you 
+should have a usable stunnel.pem in your working directory.</p>
+<p>Next is to create a configuration file for stunnel. It will direct stunnel 
+what to do. You can used the following basic file:</p>
+<p></p><blockquote><code></code><pre>; Certificate/key is needed in server mode<br>cert = /etc/stunnel/stunnel.pem<br><br><i>; Some debugging stuff useful for troubleshooting<br>debug = 7<br>foreground=yes</i>
+
+[ssyslog]
+accept  = 60514
+connect = 61514</pre>
+</blockquote><p></p>
+<p>Save this file to e.g. /etc/stunnel/syslog-server.conf. Please note that the 
+settings in <i>italics</i> are for debugging only. They run stunnel 
+with a lot of debug information in the foreground. This is very valuable while 
+you setup the system - and very useless once everything works well. So be sure 
+to remove these lines when going to production.</p>
+<p>Finally, you need to start the stunnel daemon. Under Debian, this is done via 
+"stunnel /etc/stunnel/syslog.server.conf". If you have enabled the debug 
+settings, you will immediately see a lot of nice messages.</p>
+<p>Now you have stunnel running, but it obviously unable to talk to rsyslog - 
+because it is not yet running. If not already done, configure it so that it does 
+everything you want. If in doubt, you can simply copy /etc/syslog.conf to /etc/rsyslog.conf 
+and you probably have what you want. The really important thing in rsyslogd 
+configuration is that you must make it listen to tcp port 61514 (remember: this 
+is where stunnel send the messages to). Thankfully, this is easy to achive: just 
+add "-t 61514" to the rsyslogd startup options in your system startup script. 
+After done so, start (or restart) rsyslogd.</p>
+<p>The server should now be fully operational.</p>
+<h3>Client Setup</h3>
+<p>The client setup is simpler. Most importantly, you do not need a certificate 
+(of course, you can use one if you would like to authenticate the client, but 
+this is beyond the scope of this paper). So the basic thing you need to do is 
+create the stunnel configuration file.</p>
+<p></p><blockquote><code></code><pre><i>; Some debugging stuff useful for troubleshooting<br>debug = 7<br>foreground=yes</i>
+
+<b>client=yes</b>
+
+[ssyslog]
+accept  = 127.0.0.1:61514
+connect = <font color="#ff0000">192.0.2.1</font>:60514<br></pre>
+</blockquote><p></p>
+<p>Again, the text in <i>italics</i> is for debugging purposes only. I suggest 
+you leave it in during your initial testing and then remove it. The most 
+important difference to the server configuration outlined above is the "client=yes" 
+directive. It is what makes this stunnel behave like a client. The accept 
+directive binds stunnel only to the local host, so that it is protected from 
+receiving messages from the network (somebody might fake to be the local sender). 
+The address "192.0.2.1" is the address of the server machine. You must change it 
+to match your configuration. Save this file to /etc/stunnel/syslog-client.conf.</p>
+<p>Then, start stunnel via "stunnel4 /etc/stunnel/syslog-client.conf".&nbsp; Now 
+you should see some startup messages. If no errors appear, you have a running 
+client stunnel instance.</p>
+<p>Finally, you need to tell rsyslogd to send data to the remote host. In stock 
+syslogd, you do this via the "@host" forwarding directive. The same works with 
+rsyslog, but it suppports extensions to use tcp. Add the following line to your 
+/etc/rsyslog.conf:</p>
+<p></p><blockquote><code></code><pre>*.*      @<font color="#ff0000">@</font>127.0.0.1:61514<br></pre>
+</blockquote><i><p></p>
+
+</i>
+
+<p>Please note the double at-sign (@@). This is no typo. It tells rsyslog to use 
+tcp instead of udp delivery. In this sample, all messages are forwarded to the 
+remote host. Obviously, you may want to limit this via the usual rsyslog.conf 
+settings (if in doubt, use man rsyslog.con).</p>
+<p>You do not need to add any special startup settings to rsyslog on the client. 
+Start or restart rsyslog so that the new configuration setting takes place.</p>
+<h3>Done</h3>
+<p>After following these steps, you should have a working secure syslog 
+forwarding system. To verify, you can type "logger test" or a similar smart 
+command on the client. It should show up in the respective server log file. If 
+you dig out you sniffer, you should see that the traffic on the wire is actually 
+protected. In the configuration use above, the two stunnel endpoints should be 
+quite chatty, so that you can follow the action going on on your system.</p>
+<p>If you have only basic security needs, you can probably just remove the debug 
+settings and take the rest of the configuration to production. If you are 
+security-sensitve, you should have a look at the various stunnel settings that 
+help you further secure the system.</p>
+<h2>Preventing Systems from talking directly to the rsyslog Server</h2>
+<p>It is possible that remote systems (or attackers) talk to the rsyslog server 
+by directly connecting to its port 61514. Currently (July of 2005), rsyslog does 
+not offer the ability to bind to the local host, only. This feature is planned, 
+but as long as it is missing, rsyslog must be protected via a firewall. This can 
+easily be done via e.g iptables. Just be sure not to forget it.</p>
+<h2>Conclusion</h2>
+<p>With minumal effort, you can set up a secure logging infrastructure employing 
+ssl encrypted syslog message transmission. As a side note, you also have the 
+benefit of reliable tcp delivery which is far less prone to message loss than 
+udp.</p>

+<h1>Encrypting Syslog Traffic with TLS (SSL)</h1>
+<p><small><i>Written by <a href="http://www.adiscon.com/en/people/rainer-gerhards.php">Rainer

+<h2>Abstract</h2>
+<p><i><b>In this paper, I describe how to encrypt <a href="http://www.monitorware.com/en/topics/syslog/">syslog</a>
+messages on the network.</b> Encryption
+is vital to keep the confidiental content of syslog messages secure. I
+describe the overall
+approach and provide an HOWTO do it with <a href="http://www.rsyslog.com">rsyslog's</a> TLS
+features.&nbsp;</i></p>
+<p>Please
+note that TLS is the more secure successor of SSL. While people often
+talk about "SSL encryption" they actually mean "TLS encryption". So
+don't look any further if you look for how to SSL-encrypt syslog. You
+have found the right spot.</p>
+<p>This is a quick guide. There is a more elaborate guide currently
+under construction which provides a much more secure environment. It
+is highly recommended to
+<a href="rsyslog_secure_tls.html">at least have a look at it</a>.
+<h2>Background</h2>
+<p><b>Traditional syslog is a clear-text protocol. That
+means anyone with a sniffer can have a peek at your data.</b> In
+some environments, this is no problem at all. In others, it is a huge
+setback, probably even preventing deployment of syslog solutions.
+Thankfully, there are easy ways to encrypt syslog
+communication.&nbsp;</p>
+The traditional approach involves <a href="rsyslog_stunnel.html">running
+a wrapper like stunnel around the syslog session</a>. This works
+quite well and is in widespread use. However, it is not thightly
+coupled with the main syslogd and some, even severe, problems can
+result from this (follow a mailing list thread that describes <a href="http://lists.adiscon.net/pipermail/rsyslog/2008-March/000580.html">total
+loss of syslog messages due to stunnel mode</a> and the <a href="http://rgerhards.blogspot.com/2008/04/on-unreliability-of-plain-tcp-syslog.html">unreliability
+of TCP syslog</a>).
+<p><a href="gssapi.html">Rsyslog supports syslog via
+GSSAP</a>I since long to overcome these limitatinos. However,
+syslog via GSSAPI is a rsyslog-exclusive transfer mode and it requires
+a proper Kerberos environment. As such, it isn't a really universal
+solution. The <a href="http://www.ietf.org/">IETF</a>
+has begun standardizing syslog over plain tcp over
+TLS for a while now. While I am not fully satisfied with the results so
+far, this obviously has the&nbsp; potential to become the long-term
+solution. The Internet Draft in question, syslog-transport-tls has been
+dormant for some time but is now (May of 2008) again being worked on. I
+expect it to turn into a RFC within the next 12 month (but don't take
+this for granted ;)). I didn't want to wait for it, because there
+obviously is need for TLS syslog right now (and, honestly, I have
+waited long enough...). Consequently, I have
+implemented the current draft, with some interpretations I made (there
+will be a compliance doc soon). So in essence, a TLS-protected syslog
+transfer mode is available right now. As a side-note, Rsyslog
+is&nbsp;the world's first
+implementation of syslog-transport-tls.</p>
+<p>Please note that in theory it should be compatible with other,
+non IETF syslog-transport-tls implementations. If you would like to run
+it with something else, please let us know so that we can create a
+compatibility list (and implement compatbility where it doesn't yet
+exist).&nbsp;</p>
+<h2>Overall System Setup</h2>
+<p>Encryption requires a reliable stream. So It will not work
+over UDP syslog. In rsyslog, network transports utilize a so-called
+"network stream layer" (netstream for short). This layer provides a
+unified view of the transport to the application layer. The plain TCP
+syslog sender and receiver are the upper layer. The driver layer
+currently consists of the "ptcp" and "gtls" library plugins. "ptcp"
+stands for "plain tcp" and is used for unencrypted message transfer. It
+is also used internally by the gtls driver, so it must always be
+present on a system. The "gtls" driver is for GnutTLS, a TLS library.
+It is used for encrypted message transfer. In the future, additional
+drivers will become available (most importantly, we would like to
+include a driver for NSS).</p>
+<p>What you need to do to build an encrypted syslog channel is to
+simply use the proper netstream drivers on both the client and the
+server. Client, in the sense of this document, is the rsyslog system
+that is sending syslog messages to a remote (central) loghost, which is
+called the server. In short, the setup is as follows:</p>
+<p><b>Client</b></p>
+<ul>
+<li>forwards messages via plain tcp syslog using gtls netstream
+driver to central sever on port 10514<br>
+</li>
+</ul>
+<p><b>Server</b></p>
+<ul>
+<li>accept incoming messages via plain tcp syslog using gtls
+netstream driver on port 10514</li>
+</ul>
+<h2>Setting up the system</h2>
+<h3>Server Setup</h3>
+<p>At the server, you need to have a digital certificate. That
+certificate enables SSL operation, as it provides the necessary crypto
+keys being used to secure the connection. There is a set of default
+certificates in ./contrib/gnutls. These are key.pem and cert.pem. These
+are&nbsp;good for testing. If you use it in production,
+it is very easy to break into your secure channel as everybody is able
+to get hold of your private key. So it is&nbsp;a good idea to
+generate the key and certificate yourself.</p>
+<p>You also need a root CA certificate. Again, there is a sample
+CA certificate in ./contrib/gnutls, named ca.cert. It is suggested to
+generate your own.</p>
+<p>To configure the server, you need to tell it where are its
+certificate files, to use the gtls driver and start up a listener. This
+is done as follows:<br>
+</p>
+<blockquote><code></code>
+<pre># make gtls driver the default
+$DefaultNetstreamDriver gtls
+
+# certificate files
+$DefaultNetstreamDriverCAFile /path/to/contrib/gnutls/ca.pem
+$DefaultNetstreamDriverCertFile /path/to/contrib/gnutls/cert.pem
+$DefaultNetstreamDriverKeyFile /path/to/contrib/gnutls/key.pem
+
+$ModLoad /home/rger/proj/rsyslog/plugins/imtcp/.libs/imtcp # load listener
+
+$InputTCPServerStreamDriverMode 1 # run driver in TLS-only mode
+$InputTCPServerStreamDriverAuthMode anon # client is NOT authenticated
+$InputTCPServerRun 10514 # start up listener at port 10514
+</pre>
+</blockquote>
+This is all you need to do. You can use the rest of your rsyslog.conf
+together with this configuration. The way messages are received does
+not interfer with any other option, so you are able to do anything else
+you like without any restrictions.
+<p>Restart (or HUP) rsyslogd. The server should now be fully
+operational.</p>
+<h3>Client Setup</h3>
+<p>The client setup is equally&nbsp;simple. You need less
+certificates, just the CA cert.&nbsp;</p>
+<blockquote>
+<pre># certificate files - just CA for a client
+$DefaultNetstreamDriverCAFile /path/to/contrib/gnutls/ca.pem
+
+# set up the action
+$DefaultNetstreamDriver gtls # use gtls netstream driver
+$ActionSendStreamDriverMode 1 # require TLS for the connection
+$ActionSendStreamDriverAuthMode anon # server is NOT authenticated
+*.* @@(o)server.example.net:10514 # send (all) messages
+
+</pre>
+</blockquote>
+<p>Note that we use the regular TCP forwarding syntax (@@) here.
+There is nothing special, because the encryption is handled by the
+netstream driver. So I have just forwarded every message (*.*) for
+simplicity - you can use any of rsyslog's filtering capabilities (like
+epxression-based filters or regular expressions). Note that the "(o)"
+part is not strictly necessary. It selects octet-based framing, which
+provides compatiblity to IETF's syslog-transport-tls draft. Besides
+compatibility, this is also a more reliable transfer mode, so I suggest
+to always use it.</p>
+<h3>Done</h3>
+<p>After
+following these steps, you should have a working secure
+syslog forwarding system. To verify, you can type "logger test" or a
+similar "smart" command on the client. It should show up in the
+respective server log file. If you dig out your sniffer, you should see
+that the traffic on the wire is actually protected.</p>
+<h3>Limitations</h3>
+<p>The current implementation has a number of limitations. These
+are
+being worked on. Most importantly, neither the client nor the server
+are authenticated. So while the message transfer is encrypted, you can
+not be sure which peer you are talking to. Please note that this is a
+limitation found in most real-world SSL syslog systems. Of course, that
+is not an excuse for not yet providing this feature - but it tells you
+that it is acceptable and can be worked around by proper firewalling,
+ACLs and other organizational measures. Mutual authentication will be
+added shortly to rsyslog.</p>
+<p>Secondly, the plain tcp syslog listener
+can currently listen to a single port, in a single mode. So if you use
+a TLS-based listener, you can not run unencrypted syslog on the same
+instance at the same time. A work-around is to run a second rsyslogd
+instance. This limitation, too, is scheduled to be removed soon.</p>
+<p>The
+RELP transport can currently not be protected by TLS. A work-around is
+to use stunnel. TLS support for RELP will be added once plain TCP
+syslog has sufficiently matured.</p>
+<h2>Certificates</h2>
+<p>In order to be really secure, certificates are needed. This is
+a short summary on how to generate the necessary certificates with
+GnuTLS' certtool. You can also generate certificates via other tools,
+but as we currently support GnuTLS as the only TLS library, we thought
+it is a good idea to use their tools.<br>
+</p>
+<p>Note that this section aims at people who are not involved
+with PKI at all. The main goal is to get them going in a reasonable
+secure way.&nbsp;</p>
+<h3>CA Certificate</h3>
+<p>This is used to sign all of your other certificates. The CA
+cert must be trusted by all clients and servers. The private key must
+be well-protected and not given to any third parties. The certificate
+itself can (and must) be distributed. To generate it, do the following:</p>
+<ol>
+<li>generate the private key:
+<pre>certtool --generate-privkey --outfile ca-key.pem</pre>
+<br>
+This takes a short while. Be sure to do some work on your workstation,
+it waits for radom input. Switching between windows is sufficient ;)
+</li>
+<li>now create the (self-signed) CA certificate itself:<br>
+<pre>certtool --generate-self-signed --load-privkey ca-key.pem --outfile ca.pem</pre>
+This generates the CA certificate. This command queries you for a
+number of things. Use appropriate responses. When it comes to
+certificate validity, keep in mind that you need to recreate all
+certificates when this one expires. So it may be a good idea to use a
+long period, eg. 3650 days (roughly 10 years). You need to specify that
+the certificates belongs to an authrity. The certificate is used to
+sign other certificates.<br>
+</li>
+<li>You need to distribute this certificate
+to all peers and you need to point to it via the
+$DefaultNetstreamDriverCAFile config directive. All other certificates
+will be issued by this CA.<br>
+Important: do only distribute the ca.pem, NOT ca-key.pem (the private
+key). Distributing the CA private key would totally breach security as
+everybody could issue new certificates on the behalf of this CA.
+</li>
+</ol>
+<h3>Individual Peer Certificate</h3>
+<p>Each peer (be it client, server or both), needs a certificate
+that conveys its identity. Access control is based on these
+certificates. You can, for example, configure a server to accept
+connections only from configured clients. The client ID is taken from
+the client instances certificate. So as a general rule of thumb, you
+need to create a certificate for each instance of rsyslogd that you
+run. That instance also needs the private key, so that it can properly
+decrypt the traffic. Safeguard the peer's private key file. If somebody
+gets hold of it, it can malicously pretend to be the compromised host.
+If such happens, regenerate the certificate and make sure you use a
+different name instead of the compromised one (if you use name-based
+authentication).&nbsp;</p>
+<p>These are the steps to generate the indivudual certificates
+(repeat: you need to do this for every instance, do NOT share the
+certificates created in this step):</p>
+<ol>
+<li>generate a private key (do NOT mistake this with the CA's
+private key - this one is different):<br>
+<pre>certtool --generate-privkey --outfile key.pem</pre>
+Again, this takes a short while.</li>
+<li>generate a certificate request:<br>
+<pre>certtool --generate-request --load-privkey key.pem --outfile request.pem</pre>
+If you do not have the CA's private key (because you are not authorized
+for this), you can send the certificate request to the responsible
+person. If you do this, you can skip the remaining steps, as the CA
+will provide you with the final certificate. If you submit the request
+to the CA, you need to tell the CA the answers that you would normally
+provide in step 3 below.
+</li>
+<li>Sign (validate, authorize) the certificate request and
+generate the instances certificate. You need to have the CA's
+certificate and private key for this:<br>
+<pre>certtool --generate-certificate --load-request request.pem --outfile cert.pem \<br> --load-ca-certificate ca.pem --load-ca-privkey ca-key.pem</pre>
+Answer questions as follows: Cert does not belogn to an authority; it
+is a TLS web server and client certificate; the dnsName MUST be the
+name of the peer in question (e.g. centralserver.example.net) - this is
+the name used for authenticating the peers. Please note that you may
+use an IP address in dnsName. This is a good idea if you would like to
+use default server authentication and you use selector lines with IP
+addresses (e.g. "*.* @@192.168.0.1") - in that case you need to select
+a dnsName of 192.168.0.1. But, of course, changing the server IP then
+requires generating a new certificate.</li>
+</ol>
+After you have generated the certificate, you need to place it onto the
+local machine running rsyslogd. Specify the certificate and key via the
+$DefaultNetstreamDriverCertFile /path/to/cert.pem and
+$DefaultNetstreamDriverKeyFile /path/to/key.pem configuration
+directives. Make sure that nobody has access to key.pem, as that would
+breach security. And, once again: do NOT use these files on more than
+one instance. Doing so would prevent you from distinguising between the
+instances and thus would disable useful authentication.
+<h3>Troubleshooting Certificates</h3>
+<p>If you experience trouble with your certificate setup, it may
+be
+useful to get some information on what is contained in a specific
+certificate (file). To obtain that information, do&nbsp;</p>
+<pre>$ certtool --certificate-info --infile cert.pem</pre>
+<p>where "cert.pem" can be replaced by the various certificate pem files (but it does not work with the key files).</p>
+<h2>Conclusion</h2>
+<p>With minumal effort, you can set up a secure logging
+infrastructure employing TLS encrypted syslog message transmission.</p>

+<h3>Setting up the CA</h3>
+<p>The first step is to set up a certificate authority (CA). It must be 
+maintained by a trustworthy person (or group) and approves the indentities of 
+all machines. It does so by issuing their certificates. In a small setup, the 
+administrator can provide the CA function. What is important is the the CA's 
+<span style="float: left">
+<script type="text/javascript"><!--
+google_ad_client = "pub-3204610807458280";
+/* rsyslog doc inline */
+google_ad_slot = "5958614527";
+google_ad_width = 125;
+google_ad_height = 125;
+//-->
+</script>
+<script type="text/javascript"
+src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
+</script>
+</span>
+private key is well-protocted and machine certificates are only issued if it is 
+know they are valid (in a single-admin case that means the admin should not 
+issue certificates to anyone else except himself).</p>
+<p>The CA creates a so-called self-signed certificate. That is, it approves its 
+own authenticy. This sounds useless, but the key point to understand is that 
+every machine will be provided a copy of the CA's certificate. Accepting this 
+certificate is a matter of trust. So by configuring the CA certificate, the 
+administrator tells <a href="http://www.rsyslog.com">rsyslog</a> which certificates to trust. This is the root of all 
+trust under this model. That is why the CA's private key is so important - 
+everyone getting hold of it is trusted by our rsyslog instances.</p>
+<center><img src="tls_cert_ca.jpg"></center>
+<p>To create a self-signed certificate, use the following commands with GnuTLS (which 
+is currently the only supported TLS library, what may change in the future).
+Please note that GnuTLS' tools are not installed by default on many platforms. Also,
+the tools do not necessarily come with the GnuTLS core package. If you do not
+have certtool on your system, check if there is package for the GnuTLS tools available
+(under Fedora, for example, this is named gnutls-utils-&lt;version&gt; and
+it is NOT installed by default). </p>
+<ol>
+<li>generate the private key:
+<pre>certtool --generate-privkey --outfile ca-key.pem</pre>
+<br>
+This takes a short while. Be sure to do some work on your workstation,
+it waits for radom input. Switching between windows is sufficient ;)
+</li>
+<li>now create the (self-signed) CA certificate itself:<br>
+<pre>certtool --generate-self-signed --load-privkey ca-key.pem --outfile ca.pem</pre>
+This generates the CA certificate. This command queries you for a
+number of things. Use appropriate responses. When it comes to
+certificate validity, keep in mind that you need to recreate all
+certificates when this one expires. So it may be a good idea to use a
+long period, eg. 3650 days (roughly 10 years). You need to specify that
+the certificates belongs to an authority. The certificate is used to
+sign other certificates.<br>

+<h3>Setting up a client</h3>
+<p>In this step, we configure a client machine. We from our scenario, we use
+zuse.example.net. You need to do the same steps for all other clients, too (in the
+example, that meanst turng.example.net). The client check's the server's identity and
+talks to it only if it is the expected server. This is a very important step.
+Without it, you would not detect man-in-the-middle attacks or simple malicious servers
+who try to get hold of your valuable log data.

+<p>Steps to do:
+<ul>
+<li>make sure you have a functional CA (<a href="tls_cert_ca.html">Setting up the CA</a>)
+<li>generate a machine certificate for zuse.example.net (follow instructions in
+    <a href="tls_cert_machine.html">Generating Machine Certificates</a>)
+<li>make sure you copy over ca.pem, machine-key.pem ad machine-cert.pem to the client.
+Ensure that no user except root can access them (<b>even read permissions are really bad</b>).
+<li>configure the client so that it checks the server identity and sends messages only
+if the server identity is known. Please note that you have the same options as when
+configuring a server. However, we now use a single name only, because there is only one
+central server. No using wildcards make sure that we will exclusively talk to that server
+(otherwise, a compromised client may take over its role). If you load-balance to different
+server identies, you obviously need to allow all of them. It still is suggested to use
+explcit names.
+</ul>
+<p><b>At this point, please be reminded once again that your security needs may be quite different from
+what we assume in this tutorial. Evaluate your options based on your security needs.</b>
+<h3>Sample syslog.conf</h3>
+<p>Keep in mind that this rsyslog.conf sends messages via TCP, only. Also, we do not
+show any rules to write local files. Feel free to add them.
+<code><pre>
+# make gtls driver the default
+$DefaultNetstreamDriver gtls
+
+# certificate files
+$DefaultNetstreamDriverCAFile /rsyslog/protected/ca.pem
+$DefaultNetstreamDriverCertFile /rsyslog/protected/machine-cert.pem
+$DefaultNetstreamDriverKeyFile /rsyslog/protected/machine-key.pem
+
+$ActionSendStreamDriverAuthMode x509/name
+$ActionSendStreamDriverPermittedPeer central.example.net
+$ActionSendStreamDriverMode 1 # run driver in TLS-only mode
+*.* @@central.example.net:10514 # forward everything to remote server
+</pre></code>

+<h3>Error Messages</h3>
+<p>This page covers error message you may see when setting up
+<span style="float: left">
+<script type="text/javascript"><!--

+<a href="http://www.rsyslog.com">rsyslog</a> with TLS. Please note that many
+of the message stem back to the TLS library being used. In those cases, there is
+not always a good explanation available in rsyslog alone.
+<p>A single error typically results in two or more message being emitted: (at
+least) one is the actual error cause, followed by usually one message with additional
+information (like certificate contents). In a typical system, these message should
+immediately follow each other in your log. Kepp in mind that they are reported
+as syslog.err, so you need to capture these to actually see errors (the default
+rsyslog.conf's shipped by many systems will do that, recording them e.g. in
+/etc/messages).
+<h3>certificate invalid</h3>
+<p>Sample:
+<code>
+not permitted to talk to peer, certificate invalid: <font color="red">insecure algorithm</font>
+</code>
+<p>This message may occur during connection setup. It indicates that the remote peer's
+certificate can not be accepted. The reason for this is given in the message part that
+is shown in red. Please note that this red part directly stems back to the TLS library,
+so rsyslog does acutally not have any more information about the reason. 
+<p>With GnuTLS, the following reasons have been seen in practice:
+<h4>insecure algorith</h4>
+<p>The certificate contains information on which encryption algorithms are to be used.
+This information is entered when the certificate is created.
+Some older alogrithms are no longer secure and the TLS library does not accept
+them. Thus the connection request failed. The cure is to use a certificate with sufficiently secure
+alogorithms.
+<p>Please note that noi encryption algorithm is totally secure. It only is secure based
+on our current knowledge AND on computing power available. As computers get more and more
+powerful, previously secure algorithms become insecure over time. As such, algorithms
+considered secure today may not be accepted by the TLS library in the future.
+<p>So in theory, after a system upgrade, a connection request may fail with the "insecure
+algorithm" failure without any change in rsyslog configuration or certificates. This could be
+caused by a new perception of the TLS library of what is secure and what not.
+<h3>GnuTLS error -64</h3>
+<p>Sample: <code>unexpected GnuTLS error -64 in nsd_gtls.c:517: Error while reading file.</code>
+<p>This error points to an encoding error witht the pem file in question. It means "base 64 encoding error".
+From my experience, it can be caused by a couple of things, some of them not obvious:
+<ul>
+<li>You specified a wrong file, which is not actually in .pem format
+<li>The file was incorrectly generated
+<li>I think I have also seen this when I accidently swapped private key files and
+certificate files. So double-check the type of file you are using.
+<li>It may even be a result of an access (permission) problem. In theory, that
+should lead to another error, but in practice it sometimes seems to lead to
+this -64 error.
+</ul>
+<h3>info on invalid cert</h3>
+<p>Sample:
+<code>
+info on invalid cert: peer provided 1 certificate(s). Certificate 1 info: certificate valid from Wed Jun 18 11:45:44 2008 to Sat Jun 16 11:45:53 2018; Certificate public key: RSA; DN: C=US,O=Sample Corp,OU=Certs,L=Somehwere,ST=CA,CN=somename; Issuer DN: C=US,O=Sample Corp,OU=Certs,L=Somewhere,ST=CA,CN=somename,EMAIL=xxx@example.com; SAN:DNSname: machine.example.net;
+</code>
+<p>This is <b>not</b> an error message in itself. It always follows the actual error message and
+tells you what is seen in the peer's certificate. This is done to give you a chance to evaluate
+the certificate and better understand why the initial error message was issued.
+<p>Please note that you can NOT diagnose problems based on this message alone. It follows
+in a number of error cases and does not pinpoint any problems by itself.

+<h3>generating the machine certificate</h3>
+<p>In this step, we generate certificates for each of the machines. Please note
+that both clients and servers need certificates. The certificate identifies each
+machine to the remote peer. The DNSName specified inside the certificate can
+<span style="float: left">

+be specified inside the $&lt;object&gt;PermittedPeer config statements.
+<p>For now, we assume that a single person (or group) is responsible for the whole
+rsyslog system and thus it is OK if that single person is in posession of all
+machine's private keys. This simplification permits us to use a somewhat less
+complicated way of generating the machine certificates. So, we generate both the private
+and public key on the CA (which is NOT a server!) and then copy them over to the
+respective machines.
+<p>If the roles of machine and CA administrators are split, the private key must
+be generated by the machine administrator. This is done via a certificate request.
+This request is then sent to the CA admin, which in turn generates the certificate
+(containing the public key). The CA admin then sends back the certificate to the
+machine admin, who installs it. That way, the CA admin never get's hold of the
+machine's private key. Instructions for this mode will be given in a later revision
+of this document.
+<p><b>In any case, it is vital that the machine's private key is protected. Anybody
+able to obtain that private key can imporsonate as the machine to which it belongs, thus
+breaching your security.</b>
+<h3>Sample Screen Session</h3>
+<p>Text in red is user input. Please note that for some questions, there is no

+<p><b>Please note:</b> you need to substitute the names specified below with values
+that match your environment. Most importantly, machine.example.net must be replaced
+by the actual name of the machine that will be using this certificate. For example,
+if you generate a certificate for a machine named "server.example.com", you need 
+to use that name. If you generate a certificate for "client.example.com", you need
+to use this name. Make sure that each machine certificate has a unique name. If not,
+you can not apply proper access control.

+<h3>Sample Scenario</h3>
+<p>We have a quite simple scenario. There is one central syslog server, 
+<span style="float: left">
+<script type="text/javascript"><!--
+google_ad_client = "pub-3204610807458280";

+</span>
+named central.example.net. These server is being reported to by two Linux 
+machines with name zuse.example.net and turing.example.net. Also, there is a 
+third client - ada.example.net - which send both its own messages to the central 
+server but also forwards messages receive from an UDP-only capable router. We 
+hav decided to use ada.example.net because it is in the same local network 
+segment as the router and so we enjoy TLS' security benefits for forwarding the 
+router messages inside the corporate network. All systems (except the router) use
+<a href="http://www.rsyslog.com/">rsyslog</a> as the syslog software.</p>
+<p><center><img src="tls_cert_100.jpg"></center>
+<p>Please note that the CA must not necessarily be connected to the rest of the
+network. Actually, it may be considered a security plus if it is not. If the CA
+is reachable via the regular network, it should be sufficiently secured (firewal
+rules et al). Keep in mind that if the CA's security is breached, your overall
+system security is breached.
+<p>In case the CA is compromised, you need to regenerate the CA's certificate as well
+as all individual machines certificates.

+
+<h3>Setting up the Central Server</h3>
+<p>In this step, we configure the central server. We assume it accepts messages only
+via TLS protected plain tcp based syslog from those peers that are explicitely permitted
+to send to it. The picture below show our configuration. This step configures
+the server central.example.net.
+<span style="float: left">
+<script type="text/javascript"><!--
+google_ad_client = "pub-3204610807458280";
+/* rsyslog doc inline */
+google_ad_slot = "5958614527";
+google_ad_width = 125;
+google_ad_height = 125;
+//-->

+<script type="text/javascript"
+src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
+</script>
+</span>
+<p><center><img src="tls_cert_100.jpg"></center>
+<p>Steps to do:
+<ul>
+<li>make sure you have a functional CA (<a href="tls_cert_ca.html">Setting up the CA</a>)
+<li>generate a machine certificate for central.example.net (follow instructions in
+    <a href="tls_cert_machine.html">Generating Machine Certificates</a>)
+<li>make sure you copy over ca.pem, machine-key.pem ad machine-cert.pem to the central server.
+Ensure that no user except root can access them (<b>even read permissions are really bad</b>).
+<li>configure the server so that it accepts messages from all machines in the
+example.net domain that have certificates from your CA. Alternatively, you may also
+precisely define from which machine names messages are accepted. See sample rsyslog.conf
+below.
+</ul>
+In this setup, we use wildcards to ease adding new systems. We permit the server to accept
+messages from systems whos names match *.example.net.
+<pre><code>
+$InputTCPServerStreamDriverPermittedPeer *.example.net
+</code></pre>
+This will match zuse.example.net and
+turing.example.net, but NOT pascal.otherdepartment.example.net. If the later would be desired,
+you can (and need) to include additional permitted peer config statments:
+<pre><code>
+$InputTCPServerStreamDriverPermittedPeer *.example.net
+$InputTCPServerStreamDriverPermittedPeer *.otherdepartment.example.net
+$InputTCPServerStreamDriverPermittedPeer *.example.com
+</code></pre>
+<p>As can be seen with example.com, the different permitted peers need NOT to be in a single
+domain tree. Also, individual machines can be configured. For example, if only zuse, turing
+and ada should be able to talk to the server, you can achive this by:
+<pre><code>
+$InputTCPServerStreamDriverPermittedPeer zuse.example.net
+$InputTCPServerStreamDriverPermittedPeer turing.example.net
+$InputTCPServerStreamDriverPermittedPeer ada.example.net
+</code></pre>
+<p>As an extension to the (upcoming) IETF syslog/tls standard, you can specify some text
+together with a domain component wildcard. So "*server.example.net", "server*.example.net"
+are valid permitted peers. However "server*Fix.example.net" is NOT a valid wildcard. The
+IETF standard permits no text along the wildcards.
+<p>The reason we use wildcards in the default setup is that it makes it easy to add systems
+without the need to change the central server's configuration. It is important to understand that
+the central server will accept names <b>only</b> (no exception) if the client certificate was
+signed by the CA we set up. So if someone tries to create a malicious certificate with
+a name "zuse.example.net", the server will <b>not</b> accept it. So a wildcard is safe
+as long as you ensure CA security is not breached. Actually, you authorize a client by issuing
+the certificate to it.
+<p><b>At this point, please be reminded once again that your security needs may be quite different from
+what we assume in this tutorial. Evaluate your options based on your security needs.</b>
+<h3>Sample syslog.conf</h3>
+<p>Keep in mind that this rsyslog.conf accepts messages via TCP, only. The only other
+source accepted is messages from the server itself.
+<code><pre>
+$ModLoad /home/rger/proj/rsyslog/plugins/imuxsock/.libs/imuxsock # local messages
+$ModLoad /home/rger/proj/rsyslog/plugins/imtcp/.libs/imtcp
+
+# make gtls driver the default
+$DefaultNetstreamDriver gtls
+
+# certificate files
+$DefaultNetstreamDriverCAFile /rsyslog/protected/ca.pem
+$DefaultNetstreamDriverCertFile /rsyslog/protected/machine-cert.pem

+$InputTCPServerStreamDriverPermittedPeer *.example.net
+$InputTCPServerStreamDriverMode 1 # run driver in TLS-only mode
+$InputTCPServerRun 10514 # start up listener at port 10514
+</pre></code>

+a reasonable (for most needs) secure setup for the following environment:
+<center><img src="tls_cert_100.jpg"></center>
+<p>You have learned about the security decisions involved and which we
+made in this example. <b>Be once again reminded that you must make sure yourself
+that whatever you do matches your security needs!</b> There is no guarantee that
+what we generally find useful actually is. It may even be totally unsuitable for
+your environment.
+<p>In the example, we created a rsyslog certificate authority (CA). Guard the CA's
+files. You need them whenever you need to create a new machine certificate. We also saw how
+to generate the machine certificates themselfs and distribute them to the individual
+machines. Also, you have found some configuration samples for a sever, a client and
+a syslog relay. Hopefully, this will enable you to set up a similar system in many
+environments.
+<p>Please be warned that you defined some expiration dates for the certificates.
+After they are reached, the certificates are no longer valid and rsyslog will NOT
+accept them. At that point, syslog messages will no longer be transmitted (and rsyslogd
+will heavily begin to complain). So it is a good idea to make sure that you renew the
+certificates before they expire. Recording a reminder somewhere is probably a good
+idea.
+<p>If you have any more questions, please visit the <a href="http://kb.monitorware.com/rsyslog-f40.html">rsyslog forum</a> and simply ask ;)

+<h3>Setting up the UDP syslog relay</h3>
+<p>In this step, we configure the UDP relay ada.example.net. 
+As a reminder, that machine relays messages from a local router, which only 
+supports UDP syslog, to the central syslog server. The router does not talk
+directly to it, because we would like to have TLS protection for its sensitve
+logs. If the router and the syslog relay are on a sufficiently secure private
+network, this setup can be considered reasonable secure. In any case, it is the
+best alternative among the possible configuration scenarios.

+<p>Steps to do:
+<ul>
+<li>make sure you have a functional CA (<a href="tls_cert_ca.html">Setting up the CA</a>)
+<li>generate a machine certificate for ada.example.net (follow instructions in
+    <a href="tls_cert_machine.html">Generating Machine Certificates</a>)
+<li>make sure you copy over ca.pem, machine-key.pem ad machine-cert.pem to the client.
+Ensure that no user except root can access them (<b>even read permissions are really bad</b>).
+<li>configure the client so that it checks the server identity and sends messages only
+if the server identity is known.
+</ul>
+<p>These were essentially the same steps as for any
+<a href="tls_cert_client.html">TLS syslog client</a>. We now need to add the
+capability to forward the router logs:
+<ul>
+<li>make sure that the firewall rules permit message recpetion on UDP port 514 (if you use
+a non-standard port for UDP syslog, make sure that port number is permitted).
+<li>you may want to limit who can send syslog messages via UDP. A great place to do this
+is inside the firewall, but you can also do it in rsyslog.conf via an $AllowedSender
+directive. We have used one in the sample config below. Please be aware that this is
+a kind of weak authentication, but definitely better than nothing...
+<li>add the UDP input plugin to rsyslog's config and start a UDP listener
+<li>make sure that your forwarding-filter permits to forward messages received
+from the remote router to the server. In our sample scenario, we do not need to
+add anything special, because all messages are forwarded. This includes messages
+received from remote hosts.
+</ul>
+<p><b>At this point, please be reminded once again that your security needs may be quite different from
+what we assume in this tutorial. Evaluate your options based on your security needs.</b>
+<h3>Sample syslog.conf</h3>
+<p>Keep in mind that this rsyslog.conf sends messages via TCP, only. Also, we do not
+show any rules to write local files. Feel free to add them.

+# start a UDP listener for the remote router

-.SH DESCRIPTION
-.B Rfc3195d
-is a utility for receiving syslog messages via RFC 3195. Both
-RAW and COOKED profiles are supported (but COOKED only without
-relay-specific PATH elements).
-rfc3195d accepts messages via RFC 3195 and forwards them to
-the local domain socket specified in the -p option
-(/dev/log3195 by default). There, the messages can be picked up
-by the system syslogd. While rfc3195d can work with any syslogd,
-we highly recommend using
-.B rsyslogd,
-because it has special handling
-for the messages forwarded by rfc3195d. To enable message 
-reception in
-.B rsyslogd,
-use the "-a :/dev/log3195" command line
-option (the colon in front of the socket name tells
-.B rsyslogd
-that the messages contain hostnames - this is vital to get the
-right sender name into your logs).
-
-.B Rfc3195d
-currently has very limited functionality. Most importantly,
-it does not allow to limit the senders it receives messages from.
-Documentation is also very sparse. The situation should improve over
-time as the rsyslog project is continously being enhanced.
-.LP
-.SH OPTIONS
-.TP
-.BI "\-p " "socket"
-The socket the received messages are to be sent to. If not specified,
-/dev/log3195 is used.
-.TP
-.BI "\-r " "port"
-The listen port to use. If not specified, IANA-assigned port 601 is used.
-.TP
-.B "\-d"
-Turns on debug mode.  In it, rfc3195d spits out diagnostic information
-to stdout.
-.TP
-.B "\-v"
-Print version and exit.
-.SH SIGNALS
-.B Rfc3195d
-reacts to a set of signals.
-.TP
-.B SIGTERM
-.B Rfc3195d
-terminates.
-.TP
-.B SIGUSR1
-.B Rfc3195d
-terminates.

+ * long run, this class shall provide all stream-oriented netstrmwork

+/* rsyslog.c - the main entry point into rsyslog's runtime library (RTL)
+ *
+ * This module contains all function which work on a RTL global level. It's
+ * name is abbreviated to "rsrt" (rsyslog runtime).
+ *
+ * Please note that the runtime library tends to be plugin-safe. That is, it must be
+ * initialized by calling a global initialization function. However, that 
+ * function checks if the library is already initialized and, if so, does
+ * nothing except incrementing a refeence count. Similarly, the deinit
+ * function does nothing as long as there are still other users (which
+ * is tracked via the refcount). As such, it is safe to call init and
+ * exit multiple times, as long as this are always matching calls. This
+ * capability is needed for a plugin system, where one plugin never
+ * knows what the other did. HOWEVER, as of this writing, not all runtime
+ * library objects may work cleanly without static global data (the
+ * debug system is a very good example of this). So while we aim at the
+ * ability to work well in a plugin environment, things may not really work
+ * out. If you intend to use the rsyslog runtime library inside plugins,
+ * you should investigate the situation in detail. Please note that the
+ * rsyslog project itself does not yet need this functionality - thus you
+ * can safely assume it is totally untested ;).
+ *
+ * rgerhards, 2008-04-17: I have now once again checked on the plugin-safety.
+ * Unfortunately, there is currently no hook at all with which we could
+ * abstract a global data instance class. As such, we can NOT make the
+ * runtime plugin-safe in the above-described sense. As the rsyslog
+ * project itself does not need this functionality (and it is quesationable
+ * if someone else ever will), we do currently do not make an effort to
+ * support it. So if you intend to use rsyslog runtime inside a non-rsyslog
+ * plugin system, be careful!
+ *
+ * The rsyslog runtime library is in general reentrant and thread-safe. There
+ * are some intentional exceptions (e.g. inside the msg object). These are
+ * documented. Any other threading and reentrency issue can be considered a bug.

+ * rgerhards, 2008-07-04 (happy Independence Day!): rsyslog inherited the

+ * processing, because we have ample ways to do it in rsyslog. Plus, the
+ * default main message queue will care for a somewhat longer execution time.
+ * So in short, the real fix to the problem is an architecture change. From
