Re: snort logging both to syslog and unified2

["Tudor Panaitescu" <TPanaitescu () colorcon com>]

Hi
Thanks for the reply but snort actually logs to 2 different sources right
now in my environment, syslog and unified. My plan was to log only to
unified2 but unfortunately it seems like barnyard2 1.9 (latest AFAIK) does
not work w/ syslog, tried it a few good times w/o any result. And, of
course, using unified2 implies getting rid of the -A fast in the command.

Thanks,
Tudor

Hi,

Thinking back when I setup my system like this, I believe that Snort can't
log to two different sources.  Set Snort to log to unified2 only.  Then set
barnyard2 to log to syslog and your snort database.  Works for me.

Oh, and I believe that you should not have -A on the snort command line
either.

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
