restarting syslog-ng
by Brian E. Seppanen 08 Mar '01

08 Mar '01

I'm trying to set up syslog-ng to rotate it's logs with logrotate. One question this brings to mind is whether syslog-ng will restart with the HUP signal. #/bin/kill -HUP `cat /var/run/syslog-ng.pid` Thanks, Brian Seppanen Charter Communications Regional Data Center 906-228-3100 ext 23 Marquette, MI seppy(a)chartermi.net

Filter on severity range
by Jon Marks 29 Dec '00

29 Dec '00

Hello, I'm very sorry if this is answered somewhere else, or if the answer is so obvious that it's a waste of time :) I can't see anything in the documentation which explicitly addresses this. I have a question about filtering on ranges of severities. A filter such as filter f_daemon { facility(daemon) and level(info); }; catches messages logged to the daemon facility at severity info. It differs from the traditional behavior of syslogd in that it doesn't catch severities beyond info, however. Is there a shorthand way to specify a range of priorities (i.e. to achieve behavior similar to the traditional syslogd)? Or, is it necessary to write a filter such as the following one? filter f_info { level(info) or level(notice) or .. or level(emerg); }; filter f_daemon { facility(daemon) and filter(f_info); }; Thank you very much. -- Jonathan Marks Systems Administrator, Production Systems Group Computing and Communication Services Office University of Illinois at Urbana-Champaign

Matching hostnames problem
by Keith McDuffee 28 Dec '00

28 Dec '00

One problem I've found after installing syslog-ng 1.4.10 on a Solaris 2.6 system is with repeating messages, especially those originating from remote hosts. For example, here's some lines from my config file: ---- source s_udp { udp(); }; destination d_udp { file("/var/log/remote/$HOST.$FACILITY"); }; filter f_udp { level(notice) or (facility(local0) and level(info)) or (facility(local1) and level(info)) or (facility(local2) and level(info)); }; log ( source(s_udp); filter(f_udp); destination(d_udp); }; ---- Using this configuration, I get files in /var/log/remote that look like this: hostname1.local0 hostname2.local2 hostname1.auth last.local2 See that "last.local2"? Well, "last" is not a host -- it's taking it from the log message and mistakenly turning it into a hostname. Here's a line from "last.local2": --- Dec 22 10:14:13 last message repeated 2 times --- Any idea at all how to fix that besides making a filter for any hosts named "last"? Thanks, Keith

I'm currently very busy developing Zorp (it's a proxy firewall suite at http://www.balabit.hu/products/zorp/) so I don't have too much time to spend on syslog-ng. I only write bugfixes, and merge in patches sent by others. So there's no development schedule, and I can't say anything for sure.

Syslog-ng can filter on facilities specified by number, for example: filter f_numfac { facility(16); }; This is the same as facility(local0), but the number can be anything. -- Bazsi PGP info: KeyID 9AF8D0A9 Fingerprint CD27 CFB0 802C 0944 9CFD 804E C82C 8EB1 url: http://www.balabit.hu/pgpkey.txt

syslog-ng and sendmail
by Serge van Thillo 20 Dec '00

Hi people. I compiled syslog-ng today and tried out some things. It works quite ok, there only a few things I am missing. When I log facility mail I only see to adressen. this is the same when I log everything to one file. so for example: Dec 20 02:27:34 linux sendmail[10439]: eBK1RX410437: to=<serge(a)mydomain.nl>, delay=00:00:00, xdelay=00:00:00, mailer=cyrus, pri=38193, dsn=2.0.0, stat=Sent Only the line telling me who send the message is missing. I will include the config file. Can anyone tell me what is wrong? Thanks in advance.

Can I prevent syslog-ng from prepending logs from other servers?
by Matt Mencel 20 Dec '00

20 Dec '00

I am recieving web and ftp logs from another machine on my central logging machine. Syslog-ng prepends the logs with a bunch of information that I don't need and it prevents Analog and Webalizer from parsing the logs correctly. Is there a way to tell syslog-ng not to prepend this information to certain logs? Thanks. Matt mmatt(a)freew3.com

Sendmail logs two lines for each message. The other one should be above this one in the logfile. There is nothing wrong with your configuration.
