The unix servers at my site are constantly receiving "community check" messages from a server located on our WAN, in another city. Here is the example:

Jan 23 15:41:08 eagles/usr/lib/snmp/snmpdx: [ID 686298 daemon.error] community_check();bad community from rams.nw.sw.ournetwork.com

How can I filter out these messages so that /var/adm/messages doesn't fill up with them?

Thanks

Check the man pages for:
syslog.conf
syslogd

Also look at /usr/lib/newsyslog - for moving log files before they get too big.

As far as filtering out, you can't - not without losing other errors that may not be showing up now, but you would want to see if they did show up. The syslog isn't configured to cut out one specific item. Use (e)grep -v when viewing the file to 'remove' the error.

The solution for this particular situation was to use egrep -v to filter out the unwanted messages (per your suggestion). I then went through the filtered messages file to check for any other unwanted messages (there were none). I deleted the original messages file, touched a new messages file and I'm done! The size of the new filtered messages file is only 10% of the HUGE original file.

Thanks RTM, you is my guru.
