Security Onion 20120326 now available!


Security Onion 20120326 is now available!  This resolves the following issues:

Issue 197: Snort 2.9.2.1
Issue 218: /etc/nsm/gen-msg.map out of date

New Users
New users can download and install the 20120125 ISO image using the instructions here. The step marked "Install Security Onion updates" will automatically install this update.

In-place Upgrade
Existing Security Onion users can perform an in-place upgrade using the following command (if you're behind a proxy, remember to set your proxy variables as described in the FAQ):
sudo -i "curl -L http://sourceforge.net/projects/security-onion/files/security-onion-upgrade.sh > ~/security-onion-upgrade.sh && bash ~/security-onion-upgrade.sh"
Please note that the new snort.conf will overwrite your existing snort.conf.  Your existing snort.conf will be backed up to /nsm/backup/20120326/NAME_OF_SENSOR/.  Please copy any customizations (HOME_NET, etc.) from the backup copy to the production copy /etc/nsm/NAME_OF_SENSOR/snort.conf.
