Yup barnyard2 great; what is always a good argument is I heard Snort cannot
write to database AND watch network at same time. So rather than having a
guard always watching door you have one who turns around to tell you
everything that happens before looking back :-)

So in barnyard2 to log to a remote host for typical syslog which is the
recommended line to have in barnyard2.conf? Also can I log to 2 different
destinations in the same config? i.e mysql writes remotely to one database
server and then syslog to a completely different host?

Thanks,
Kevin

I usually use unified 2 to barnyard which sends logs into mysql. Now I have
the need to send Syslog into another log collector. I haven't used syslog
for snort output in a while but I have never had these issues before.


We're sending syslog from Barnyard2 rather than Snort directly, with:

output alert_syslog: LOG_LOCAL1

- - i.e. local1 as the facility.

I think we went this way after seeing weird results
from using the syslog output plugin directly in Snort itself.


I think the code that barnyard2 is using for their syslog output is a copy
of the Snort syslog output.  I'm not sure if improvements have been made to
this code, but I'd hope so.

That being said, and I guess it bears repeating for the hundreds of new
people on the list since I last said it, Snort should output in unified2
and then barnyard2 should handle the output logging from there.
