The mysql user is root and it is configured in my barnyard2.conf. I tried blowing away my waldo file and restarting 
barnyard.

As you can see it successfully opened the spool files and it recreated the waldo file, but still nothing in my mysql db!

make sure that you have added the remote sensor to the users in mysql.   if the remote sensor is not added then you 
will not see updates.  if that is all there the other thing you can do is to blow away the waldo file and restart 
snort/barnyard

Yes I have alerts. I can see that because /var/log/snort/alert has alerts listed and 
/var/log/snort/p1p1/snort.log.1338857440 is growing.

Michael

Michael,

Have you got any rules enabled?

Did you made any action that could trigger an event?

Under normal (safe) traffic, is normal to have no events.

Hi

I?ve just configured snort Version 2.9.2.3 in a test environment in preparation for upgrading my production server.

I have it configured for unified2 output and have barnyard2 configured to output to mysql:

##  /etc/snort/p1p1/barnyard2.conf
output database: log, mysql, user=xxx password=password dbname=snorby
host=127.0.0.1 port=3306

My snort start command:
/usr/local/bin/snort -u snort -g snort -i p1p1 -c
/etc/snort/p1p1/snort.conf -D

My barnyard2 start command:
/usr/local/bin/barnyard2 -c /etc/snort/p1p1/barnyard2.conf -u snort -g
snort -d /var/log/snort/p1p1 -f snort.log -w /var/log/snort/p1p1/waldo
-D

Snort is alerting:
New-ids 13:37:02 /var/log/snort/p1p1
root # ls -la /var/log/snort/p1p1
total 24
drwxr-xr-x. 2 snort snort 4096 Jun  5 11:05 .
drwxr-xr-x. 3 snort snort 4096 Jun  1 14:34 ..
-rw-------. 1 snort snort   96 Jun  5 10:18 snort.log.1338854746
-rw-------. 1 snort snort 8011 Jun  5 12:43 snort.log.1338857440
-rw-r--r--. 1 snort snort 2056 Jun  5 12:43 waldo

And Barnyard2 is seeing the alerts. Relevant section from /var/log/messages follows:
Jun  5 11:14:30 New-ids barnyard2[1995]: database: using the "log"
facility Jun  5 11:14:30 New-ids barnyard2[1995]:

     spool directory = /var/log/snort/p1p1#012
     spool filebase  = snort.log#012
     time_stamp      = 1338857440#012
     record_idx      = 0
Jun  5 11:14:30 New-ids barnyard2[1995]: Opened spool file '/var/log/snort/p1p1/snort.log.1338857440'
Jun  5 11:14:30 New-ids barnyard2[1995]: Waiting for new data

But nothing is being written to my mysql snorby DB?

I can log into mysql using the required credentials mysql -u xxx -p
snorby

but nothing is written.
mysql> select * from event;
Empty set (0.00 sec)

I?m now lost, and would appreciate some guidance. What should I do next?

Regards,

Michael
