[Snort-users] Same question again..

On Linux 2.2.14, snort 1.8.4 build 99, I'm doing this:

Command line:

/usr/bin/snort184 -b -i ppp0 -o -c /usr/local/snort-1.8.4/snort184.conf

Relevant snort.conf:

# alert_syslog: log alerts to syslog
# ----------------------------------
# Use one or more syslog facilities as arguments
# output alert_syslog: LOG_AUTH LOG_ALERT 

output alert_syslog: LOG_DAEMON LOG_ALERT
# keep as from 1.8.2 - this is FACILITY-LEVEL, I believe.. 
# -------------------------------------------------
# output alert_full

output alert_full: /var/log/snort/alert184.full
# keep as from 1.8.2 # attempted in snort182.conf for snort 1.8.2 11/25/01 - works ;-)
# attempted in snort18REL.conf for snort 1.8.1-RELEASE
# hasn't been shown in snort.conf for several releases: works as from 1.7

This binary logs to this sort of a file, for example:

4678983 May 20 15:19 snort-0520 at ...5939...

and alerts go to this sort of a file:

11226 May 20 15:14 alert184.full-0520 at ...5939...

and syslog get alerts, and logcheck picks them up, thus:

Security Violations
May 20 15:14:35 greatwall snort: [1:0:0] TCP to 1433 MS MySQL server {TCP}
+ ->

So this works for me...
