Subject: [syslog-ng] Newbie Question

All,

I am working on creating a logging host for some network hardware.  Being new to lunix and syslog-ng I am a little confused to how to keep the remote syslog messages from showing up in the system log files.  I had to rem out the messages and and localmessages do to they are filling to fast.  Any advice would be greatly appreciated.

Don R.
