Add:

 

output alert_fast: /dir/dir/snortalert.fast

 

to your snort.conf.  It’s not syslog, but better.

Hi Jeremy,

 

How many rules would be require in OSSEC to suppress those entries! ;)  The issue is how to make Snort write to a 
different file than syslog.  I do not wish to suppress the Snort info just redirect to a different file so that I can 
pick the juicy bits out to monitor.  Appreciate the input.

 

Thanks.

In OSSEC make a local rule to ignore the file and the process?

 

Or setup snort to not output to syslog..

 

and you might try running snort with the '-q' flag and see if it's quieter in the logs.

Hi,

When Snort starts it writes specific information to /var/log/messages eg.

How can I redirect those messages to a separate file as it plays havoc with OSSEC :) I have tried adding snort.none to 
rsyslog.conf for /var/log/messages and then added snort.* to direct too another file. That did not work :(

Any thoughts please ?
