I can use it in the filter section , but the source itself is not getting updated so filter option may be unused. I can source a file but the audit logs does not write to a file , they write to proprietary syslog's facility.level Is there a solution , i have hit a road block Any information , documentation of how i can include the facility.level into syslog-ng would be helpful source s_local { system(); sun-streams("/dev/log" door("/etc/.syslog_door")); }; # Filters #filter f_local6 { facility(local6); }; Do i include any other keywords apart from system in the source s_local line Thanks -- Configure bugmail: https://bugzilla.balabit.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

IPv6 rewrite rule PVCE
by strife＠riseup.net 14 Feb '13

14 Feb '13

Hi, I want to anonymize certain logs, ie. remove IP addresses. Thanks to the advice/experiments by Micah from Riseup, I have the following. It works fine for IPv4: rewrite r_ip { subst('([[:digit:]]{1,3}\.){3}[[:digit:]]{1,3}', "\[REDACTED\]", value("MESSAGE"), type("pcre"), flags("global")); }; I tried to extend this to IPv6 using the IPV6 PCRE expression found at http://home.deds.nl/~aeron/regex/ : subst('/(((?=.*(::))(?!.*\3.+\3))\3?|([\dA-F]{1,4}(\3|:\b|$)|\2))(?4){5}((?4){2}|(((2[0-4]|1\d|[1-9])?\d|25[0-5])\.?\b){4})\z/i', "\[REDACTED\]", value("MESSAGE"), type("pcre"), flags("global")); When I test the expression using pcretest, it successfully matches IPv6 addresses in text. In syslog-ng, it does not. Any ideas? Thanks! -- strife

[Bug 172] New: tcp() destination driver ignores ts_format() parameter

https://bugzilla.balabit.com/show_bug.cgi?id=172 Summary: tcp() destination driver ignores ts_format() parameter Product: syslog-ng Version: 3.3.x Platform: PC OS/Version: Linux Status: NEW Severity: minor Priority: unspecified Component: syslog-ng AssignedTo: bazsi(a)balabit.hu ReportedBy: chiestand(a)salk.edu Type of the Report: bug Estimated Hours: 0.0 The documentation (http://www.balabit.com/sites/default/files/syslog-ng-ose-v3.3-guide-admin-e…) states that you may use the ts_format() paramater to modify the timestamp format. However this parameter does not work, rfc3164 format seems to be used no matter what you specify in ts_format(). So either the documentation is wrong or there is a bug. I am running 3.3.4 on Debian Wheezy. I also had the problem running 3.1 in Debian Squeeze. my driver: destination My_Syslog { tcp("syslog.server.salk.edu" port(514) ts_format(iso) ); }; log { source(s_src); destination(My_Syslog); }; tcpdump: @.m..<hw<86>Apr 6 01:24:01 host CRON[1923]: pam_unix(cron:session): session closed for user root I emailed the mailing list on this issue, the thread can be viewed here: https://lists.balabit.hu/pipermail/syslog-ng/2012-April/018638.html -- Configure bugmail: https://bugzilla.balabit.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

[Bug 215] New: syslog-ng v3 - tcp() does not support no-multi-line as docs reference.
by bugzilla＠bugzilla.balabit.com 13 Feb '13

13 Feb '13

https://bugzilla.balabit.com/show_bug.cgi?id=215 Summary: syslog-ng v3 - tcp() does not support no-multi-line as docs reference. Product: syslog-ng Version: 3.3.x Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: unspecified Component: syslog-ng AssignedTo: bazsi(a)balabit.hu ReportedBy: balabit(a)32ths.com Type of the Report: --- Estimated Hours: 0.0 So after doing some test cases, I've noticed that on no-multi-line is not stripping newlines on v3.3.7. I've not tested previous versions yet. Here is my syslog-ng config: source s_net_tcp { tcp(ip(0.0.0.0) port(514) flags(no-multi-line)); }; destination all { file("/var/log/all"); }; log { source(s_net_tcp); destination(all); flags(final); }; I've also attempted to do this with no-parse flags passed in to no avail. When using the udp() source, it works just fine. My test case: # cat blah line1 line2 line3 # cat blah | nc -r -n myhost 514 And on "myhost" Jan 2 12:25:16 192.2.0.1 line1 Jan 2 12:25:16 192.2.0.1 line2 Jan 2 12:25:16 192.2.0.1 line3 So I assume this has something to do with it: https://bugzilla.balabit.com/show_bug.cgi?id=74 Particularly about newlines being message terminators over tcp(), however, why do the docs even say tcp() supports the no-multi-line flag? Maybe there is a way to adjust the terminator if this is the case? I must admit, I was curious what syslog-ng would do if the message size exceeded the mtu of the network. With UDP, I assume the end of the packet is the end of the message so any messages large enough to span two udp packets would actually be two log entries. I assumed it would also be the case with TCP, even if it is stream based. So the potential problems I see are: 1. tcp() doesn't really support no-multi-line (bug) or 2. the docs should be updated to not say it supports no-multi-line (bug) or 3. I've overlooked the doc references or 4. I'm missing some option (terminator?) in order to get tcp() to work with no-multi-line. (env) Thanks as always, - Mike -- Configure bugmail: https://bugzilla.balabit.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

Systemd troubles: incompatibility with journald ?
by Guillaume Rousse 08 Feb '13

08 Feb '13

Hello list. I'm unable to run syslog-ng, whatever the version (I tried 3.3.6 and 3.4.1), on a recent system using systemd (mageia cauldron 64 bits, systemd 195). As soon as I'm launching syslog-ng, systemd and systemd-journal cpu usages reach 80/95%, and systemd fill dmesg log with this kind of message: [ 5962.484250] systemd[1]: syslog-ng.service start request repeated too quickly, refusing to start I tried to disable journald, but i didn't suceed. I also found indication of using the journald socket ( /run/systemd/journal/syslog) instead of /dev/log in syslog-ng configuration, but it doesn't change much. Also, the fedora package for syslog-ng doesn't contains anything special, either in default configuration, or in systemd service unit (excepted a patch to force pid file location). So, I'm a bit lost here... There is a user bug report on this issue: https://bugs.mageia.org/show_bug.cgi?id=8944 -- BOFH excuse #223: The lines are all busy (busied out, that is -- why let them in to begin with?).
