Show us the contents of your /etc/syslog.conf

I had a problem like this too, and it also drove me nuts.

At least on my RH system, there is a file /etc/sysconfig/syslog.
This file contains optional settings, including logging levels,
for BOTH syslogd and klogd!
In this file are some lines like this:

 # See klogd(8) for more details
 KLOGD_OPTIONS="-x -c 1"

I added the -c 1 to KLOGD_OPTIONS so that
only high priority messages would print.
Look at the man page for more.

Hope this helps,

Jim

OT: Logs on console

[Victor Wren]

This is off-topic, but IPTABLES is the only place I have this problem.  I've 
tried several different configurations to try to stop it from logging dropped 
packets to my monitor.  I've put "kern.none /dev/console" in my syslog.conf, 
and it is STILL throwing the logs entries to the monitor, even when nobody is 
logged in!  I've got all my log entries set to --log-level info, and they're 
getting properly logged to an iptables logfile, but they are still showing up 
on the screen (the tutorials say this isn't an iptables issue, but ONLY the 
iptables logs are showing up on the screen).  I've been searching the 
internet for days trying to STOP THE MADNESS!

Anybody got any suggestions?

auth,authpriv.* -/var/log/auth
*.*;auth,authpriv.none -/var/log/messages
kern.none /dev/console
daemon.* -/var/log/daemon
kern.* -/var/log/kern
kern.=info -/var/log/iptables
mail.* -/var/log/mail
user.* -/var/log/user
cron.* -/var/log/cron
*.emerg *
local7.* /var/log/boot.log

I think I may have found a clue.  kernel message logging is handled by klogd. 
 the manfile for klogd says that it defaults to putting all messages of 
priority higher than 7 (debug) to the screen (info is 6) unless launched with 
"-c [level]"  I see no mention of any use of a configuration file in klogd, 
and it appears to hand kernel messages to syslogd after prioritizing, but has 
the ability to send messages to the screen (or files) itself.

Ha.  Changing it to klogd -c 3" seems to have cured it.  Now to fix it on my 
home network!

This is done by printk, and it can be changed via sysct, look what i
have in sysctl to stop printk showing the logs to the monitor:
kernel.printk= 3 4 1 7
or:
echo "3 4 1 7" > /proc/sys/kernel/printk
