New NSM and Setup packages available

I've updated our NSM and Setup packages to resolve a few issues:

Issue 429: nsm_server_clear needs latest Squert database updates
https://code.google.com/p/security-onion/issues/detail?id=429

Issue 451: nsm_sensor_clean should purge old files in /nsm/bro/extracted
https://code.google.com/p/security-onion/issues/detail?id=451

Issue 454: Disabling PADS agent blocks PRADS and results in no SANCP
records flowing
https://code.google.com/p/security-onion/issues/detail?id=454
(thanks to Kevin Branch for the patch)

Issue 435: Setup should allow you to set PF_RING min_num_slots
https://code.google.com/p/security-onion/issues/detail?id=435

Issue 446: Setup should delete /var/lib/sphinxsearch/data/binlog*
https://code.google.com/p/security-onion/issues/detail?id=446

Issue 452: Setup phase 2 should populate sniffing interfaces from
/etc/network/interfaces
https://code.google.com/p/security-onion/issues/detail?id=452

Issue 439: /etc/cron.d/sensor-newday updates
https://code.google.com/p/security-onion/issues/detail?id=439

Issue 440: BPF JIT addition to /etc/sysctl.d/10-securityonion.conf
https://code.google.com/p/security-onion/issues/detail?id=440

The new packages are as follows:
securityonion-nsmnow-admin-scripts - 20120724-0ubuntu0securityonion66
securityonion-setup - 20120912-0ubuntu0securityonion92

They have been tested by the following (thanks!):
David Zawdie

Setup now selects interfaces based on /etc/network/interfaces
If you allow Setup to configure /etc/network/interfaces, then it will use that information later to automatically select the proper interface(s) for monitoring:

PF_RING min_num_slots
Setup now creates /etc/modprobe.d/pf_ring.conf to set parameters for the PF_RING kernel module.  If you run Quick Setup, it will just use the default value of 4096 for min_num_slots.  However, if you choose Advanced Setup, you will have the opportunity to change that default value.

If you've already run Setup and want to modify min_num_slots, you can manually create /etc/modprobe.d/pf_ring.conf.  For example, to increase min_num_slots to 65534, do the following:
echo "options pf_ring transparent_mode=0 min_num_slots=65534" | sudo tee /etc/modprobe.d/pf_ring.conf
After creating /etc/modprobe.d/pf_ring.conf, you'll need to reload the PF_RING module as follows (or just reboot):
sudo nsm_sensor_ps-stop
sudo rmmod pf_ring
sudo nsm_sensor_ps-start

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