New securityonion-et-rules package

I've updated our securityonion-et-rules package in preparation for our upcoming 12.04.5.1 ISO image.  This is a static set of free NIDS rules from Emerging Threats that is only used if you have LOCAL_NIDS_RULE_TUNING=yes in /etc/nsm/securityonion.conf (most users should have LOCAL_NIDS_RULE_TUNING=no which causes PulledPork to download updated rules from the Internet).

This package has been tested by the following (thanks!):
David Zawdie

New NSM and ossec_agent.tcl packages resolve several issues

Brian Kellogg submitted a patch for ossec_agent.tcl that allows you to enable or disable DNS lookups.  Thanks, Brian!  I've packaged this and also updated the NSM package to resolve several issues.

The new packages are as follows:

securityonion-nsmnow-admin-scripts - 20120724-0ubuntu0securityonion114
securityonion-sguil-agent-ossec - 20120726-0ubuntu0securityonion7

These new packages should resolve the following issues:

Issue 684: NSM: nsm_server_ps-start needs to create /var/log/sguild/ if it doesn't already exist
https://code.google.com/p/security-onion/issues/detail?id=684

Issue 686: NSM: nsm_server_ps-start needs to set permissions on /var/log/nsm/so-elsa/ properly
https://code.google.com/p/security-onion/issues/detail?id=686

Issue 687: NSM: nsm_sensor_ps-start should set permissions on /var/log/nsm/HOSTNAME-INTERFACE/ properly
https://code.google.com/p/security-onion/issues/detail?id=687

Issue 689: NSM: add USE_DNS option to ossec_agent.conf
https://code.google.com/p/security-onion/issues/detail?id=689

Issue 688: ossec_agent: add option to disable DNS lookups
https://code.google.com/p/security-onion/issues/detail?id=688

These new packages have been tested by David Zawdie (thanks!).

Release Notes
After updating to the new packages, the next time that the NSM scripts start ossec_agent.tcl, they will add a new USE_DNS option to /etc/nsm/ossec/ossec_agent.conf and default it to 0 (disabled).  This results in much better performance for ossec_agent.tcl.

If you need to revert to the previous behavior of DNS lookups enabled and don't mind the additional lookup delay, you can change USE_DNS to 1 (enabled) and then restart ossec_agent.tcl:
sudo nsm_sensor_ps-restart --only-ossec-agent
Also note that these packages move ossec_agent.tcl to /usr/bin/.

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