I need to reduce the logging in the /var/log/messages file. I do not want the webserver activities logged on this server. I have many of the following:

Try it yourself and see: (as root) echo "This is a wall message" |wall

Cool, in the CLI and KDE! Say, in the syslog.conf: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # # Warnings in one file # *.=warning;*.=err -/var/log/warn <========== # *.crit /var/log/warn *.crit;kern.none /var/log/critical <========== kern.* /var/log/kernel # # save the rest in one file # *.*;mail.none;news.none;kern.none -/var/log/messages # # enable this, if you want to keep all messages # in one file *.* -/var/log/allmessages # Emergency messages will be displayed using wall # *.=emerg * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1.

I hate it. When you are in an emergency, trying to type commands to solve the emergency, and getting in the middle the "wall" message, which doesn't allow you to properly see what you type, then you will think if it is cool or a pest.

Say, in the syslog.conf:

*.=warning;*.=err -/var/log/warn <========== # *.crit /var/log/warn

1. What is the effect when a leading dash stands befpre the "-/var/log/warn" and none stand before "/var/log/critical"?

Entries with "-" are cached, and without the dash, are not: they are written instantly to the disk. This can slow the system noticeably, but is important in emergencies, if the system crashes.

2. Will the /var/log/kernel file and /var/log/allmessages be created automatically, or is there a way to create syslogd files?

Yes, they are created automatically. - -- Cheers, Carlos E.

/etc/syslog.conf (on a SLES 9 system)

Ah, that's not syslog-ng (next generation syslog). You have the classic one, it has less options to configure.

# # Warnings in one file # *.=warning;*.=err -/var/log/warn # *.crit /var/log/warn *.crit;kern.none /var/log/critical kern.* /var/log/kernel

I would use "-/var/log/kernel",, I think - unless I'm investigating a bug.

# save the rest in one file # *.*;mail.none;news.none;kern.none -/var/log/messages

# # enable this, if you want to keep all messages # in one file *.* -/var/log/allmessages

# Emergency messages will be displayed using wall # *.=emerg *

I have some problems with a database. It reports into the messages log file.

What's the problem, you want it somewhere else? There is little control with syslog, that's why syslog-ng is better.

The kernel and critical messages now goes to kernel and critical log files respectively, and just to make sure nothing gets lost all messages also goes to the allmessages log file.

Nothing gets lost, unless you mess too much with the configuration :-p The use of the "allmessages" is that, in case of problems, you have all messages in a single file and can see what is happening on other daemons different than the one you investigate. I don't use it. If I need it, I would create it and rotate soon.

OpenSUSE 10.3 does not have a "man syslog.conf" manpage (No manual entry for syslog.conf), perhaps named something else now; syslog.conf does not exist under /etc/. Where is it (it's equivalent)? Looking at /etc/init.d/syslog it seems to use /etc/syslog-ng/syslog-ng.conf and /etc/syslogd with /etc/syslog.conf. I do not see a syslog.conf on my 10.3 systems though?

You choose syslog or syslog-ng, not both. You will have the man page of the one you have installed, not the other. Same applies to the configuration files, which are quite different. The 10.3 systems have the -ng version by default.

# set daemon dependent variables case "$SYSLOG_DAEMON" in syslog-ng) syslog=syslog-ng config=/etc/syslog-ng/syslog-ng.conf params="$SYSLOG_NG_PARAMS" ;; *) syslog=syslogd config=/etc/syslog.conf params="$SYSLOGD_PARAMS" ;; esac

Question: What does the bracket behind syslog-ng) and the *) mean? (I'm no programmer)

If you have syslog-ng installed the script will define certain variables, and else it means you have syslogd and certain other variables. Nothing to worry about :-) - -- Cheers, Carlos E.
