Snort 2.9.7 and Daq 2.0.4 now available!

Snort 2.9.7 and Daq 2.0.4 were recently released:

I've updated our packages:
securityonion-daq - 2.0.4-0ubuntu0securityonion2
securityonion-pfring-daq - 20121107-0ubuntu0securityonion9
securityonion-snort -

These new packages should resolve the following issues:

Issue 636: Snort

Issue 637: Snort DAQ 2.0.4

Issue 648: Rebuild securityonion-pfring-daq for new DAQ

The new packages have been tested by the following (thanks!):
Eddy Simons
Ronny Vaningh
David Zawdie

The new packages are now available in our stable repo.  Please see the following page for full update instructions:

These updates will back up each of your existing snort.conf files to snort.conf.bak.  You'll then need to do the following:

  • re-apply any local customizations to your snort.conf files
  • update ruleset and restart Snort/Suricata as follows:
sudo rule-update
If you get an error like the following:
ERROR: The dynamic detection library "/usr/local/lib/snort_dynamicrules/" version 1.0 compiled with dynamic engine library version 2.1 isn't compatible with the current dynamic engine library "/usr/lib/snort_dynamicengine/" version 2.4.
then please see:'s_now_saying_'ERROR:_The_d

"sudo soup" will ask you to check/update your snort.conf file(s)

"sudo rule-update" will download the updated ruleset and restart Snort
