Re: snort logging both to syslog and unified2

You can also replace the @1.1.1.1 with a file and path like /var/log/snort/snort.alert

Vi /etc/syslog.conf

Local0.*    @1.1.1.1 <replace this 1.1.1.1. with your syslog server IP>


Service syslog restart

Hi

I was trying to enable logging on snort together w/ barnyard2 w/ unified2 and it looks like something is not working 
properly when trying to have both logging alerts to syslog and also via barnyard2. It also looks like the syslog output 
plugin of barnyard2 (version 1.9) doesn't seem to be working at all but this is another part of the story

1. Right now I have snort running + the good old barnyard and the settings in snort.conf for logging are:

output log_unified: filename snort-unified.log, limit 128
output alert_syslog: LOG_LOCAL0 LOG_ALERT
output unified2: filename snort.log, limit 128

and the run options are: -A fast -d -D -i eth1 -u root -g snort -c /etc/snort/snort.conf -l /var/log/snort

in this scenario unified works, syslog works but unified2 doesn't work (no updates in the unified2 log file)

2. snort conf:
output alert_syslog: LOG_LOCAL0 LOG_ALERT
output unified2: filename snort.log, limit 128

run options: -A fast -d -D -i eth1 -u root -g snort -c /etc/snort/snort.conf -l /var/log/snort

in this scenario both unified2 and syslog seem to be working fine. However, barnyard2 doesn't seem to be able to 
process anything, nothing shows up in base.

3. snort conf:
output alert_syslog: LOG_LOCAL0 LOG_ALERT
output unified2: filename snort.log, limit 128

run options: -d -D -i eth1 -u root -g snort -c /etc/snort/snort.conf -l /var/log/snort

unified2 seems to be working OK but syslog is broken; barnyard2 sends data to base but nothing shows up in the syslog

Any ideas anyone ?

Thanks in advance
Tudor
