syslog-ng 1.3.7 released
by Balazs Scheidler 09 Dec '99

09 Dec '99

Hi, I've released syslog-ng 1.3.7, which fixes the remaining SIGHUP bugs, and adds two global configuration options: * use_dns() yes/no enables or disables DNS lookups * use_fqdn() yes/no enables or disables FQDN usage Note that these are not too well tested (tm). Since there's a major bug in syslog-ng 1.2.x, which is fixed by 1.3.x, and is cannot be easily backported, I am thinking about releasing 1.4.0 before adding further features. (the bug is that all AF_UNIX and AF_INET connections are dropped when syslog-ng is reinitialized) So please _test_ this release as much as you can, and I'll release 1.4.0 before christmas. -- Bazsi PGP info: KeyID 9AF8D0A9 Fingerprint CD27 CFB0 802C 0944 9CFD 804E C82C 8EB1 url: http://www.balabit.hu/pgpkey.txt

Hi, No, it didn't help. Now it just dies silently, not even a work on the console. The only thing I can see is that if I start the old syslogd immediately after syslog-ng died on HUP, I get the following on the console: syslogd: cannot create /var/run/log: Address already in use Cheers, GLZ -----Original Message----- From: Balazs Scheidler [mailto:bazsi@balabit.hu] Sent: Tuesday, December 07, 1999 10:52 PM To: syslog-ng(a)venus.terrasoft.hu Subject: Re: [syslog-ng] SIGHUP kills syslog-ng on FreeBSD 3-STABLE On Tue, Dec 07, 1999 at 09:37:44PM +0100, Lowkrantz, Goran wrote: > Hi, > > Here it is. This patch should solve the problem with SIGHUP, because it drops messages while the configuration is initialized. The real problem is not solved though, the error message says that for some reason syslog-ng cannot bind to 0.0.0.0:514.

Config file size and performance
by ger 09 Dec '99

09 Dec '99

Hi, I'm configuring syslog-ng for use on a central log server, processing logs from 60 busy syslog clients, and I've realised that without hostname macro expansion in the config file I'm going to end up with a file >600 lines long. Is this likely to cause performance problems with syslog-ng when it's trying to compare each syslog packet against this kind of filter/action list, and has anyone else used it in a similar environment? Thanks, Ger. -- Ger Mulcahy, Technical Consultant, Harvard Business School

Host Seperation
by Nigel Bovey 09 Dec '99

09 Dec '99

Hi, We run a rather large network, and are looking at running a secured machine for syslog, running syslog-ng hopefully. Obviously, we want to seperate out the log files for each host. Due to the number of hosts, this looks most easily done with the latest beta having the $HOST variable. So its syslog-ng 1.3.6 on debian running 2.2.12 . I made a rough fast configuration (see below). The idea is that the files end up in /syslog/hostname/file. Now, I've turned long_hostnames(on) which I guessed (docs are rather vague on most things) would make it use long host names for comparisons. To test, I didn't create the /syslog/name directories, and ran syslog-ng -d -v and it came up with "unable to open /syslog/max1/debug". Obviously this is incorrect as I wanted it to have a long host name. I thought the obvious method here, is to just remove hostnames all together, and use ip addresses (we use ip's for all radius related stuff, to stop dns dependency). So I remove resolv.conf and restart it with syslog-ng -d -v, this time it comes up with "unable to open /syslog/1.1.1.1/debug" which is fine. So I create the directory 1.1.1.1 and restart the daemon, now it comes up with "unable to write to /syslog/1.1.1.1/debug, its a directory". I switch the names back on and try, and it writes the file fine under /syslog/max1/debug. Turn names off again, and once again it will not write the file. Any ideas ? or is this a bug that may be fixed soon =) The program looks great from where I am standing, if I could sort out this problem. My other annoyance, is that it does partial name matches, unless there is some way to turn this off that I havn't come across. Even with ip addresses, using host(1.1.1.1) matches 1.1.1.1 and 1.1.1.10,100,101 etc etc. Any help greatly appreciated. --- Nigel Bovey IHUG Network Operations Team -------------------------------------------------------------------------- options { long_hostnames(on); sync(0); }; source src { unix-stream("/dev/log"); internal(); udp(ip(0.0.0.0) port(514)); }; # filters filter f_auth { facility(auth, authpriv); }; filter f_cron { facility(cron); }; filter f_daemon { facility(daemon); }; filter f_kern { facility(kern); }; filter f_lpr { facility(lpr); }; filter f_mail { facility(mail); }; filter f_user { facility(user); }; filter f_uucp { facility(cron); }; filter f_news { facility(news); }; filter f_debug { not facility(auth, authpriv, news, mail); }; filter f_messages { level(info..warn); }; filter f_emergency { level(emerg); }; # destinations destination auth { file("/syslog/$HOST/auth"); }; destination cron { file("/syslog/$HOST/cron"); }; destination daemon { file("/syslog/$HOST/daemon"); }; destination kern { file("/syslog/$HOST/kern"); }; destination lpr { file("/syslog/$HOST/lpr"); }; destination mail { file("/syslog/$HOST/mail"); }; destination user { file("/syslog/$HOST/user"); }; destination uucp { file("/syslog/$HOST/uucp"); }; destination news { file("/syslog/$HOST/news"); }; destination debug { file("/syslog/$HOST/debug"); }; destination emergency { file("/syslog/$HOST/emergency"); }; destination messages { file("/syslog/$HOST/messages"); }; # log statements log { source(src); filter(f_auth); destination(auth); }; log { source(src); filter(f_cron); destination(cron); }; log { source(src); filter(f_daemon); destination(daemon); }; log { source(src); filter(f_kern); destination(kern); }; log { source(src); filter(f_lpr); destination(lpr); }; log { source(src); filter(f_mail); destination(mail); }; log { source(src); filter(f_user); destination(user); }; log { source(src); filter(f_uucp); destination(uucp); }; log { source(src); filter(f_news); destination(news); }; log { source(src); filter(f_debug); destination(debug); }; log { source(src); filter(f_messages); destination(messages); }; log { source(src); filter(f_emergency); destination(emergency); };
