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:

New securityonion-sostat package available

I've packaged a new version of sostat that resolves a few issues:

Issue 437: sostat: more detailed interface stats via ip(8)
https://code.google.com/p/security-onion/issues/detail?id=437

Issue 457: sostat: add /proc/net/pf_ring/info

Issue 458: sostat: include pf_ring Slots

Issue 459: sostat: netsniff-ng loss output incorrect when running BPF
https://code.google.com/p/security-onion/issues/detail?id=459

New securityonion-setup package available

I've packaged a new version of Setup that resolves a couple of issues:

Issue 436: sosetup-network: replace ifconfig with iproute2's ip tool
https://code.google.com/p/security-onion/issues/detail?id=436
This patch from Jon Schipp updates sosetup-network so that it uses "ip" instead of "ifconfig".

Issue 441: sosetup-network shouldn't stop network-manager
https://code.google.com/p/security-onion/issues/detail?id=441
The last release of sosetup added a new question to sosetup-network to allow you to modify /etc/network/interfaces and then have the choice to not immediately reboot. If you did this over "ssh -X" it would stop Network Manager which would drop your ssh connection before it could ask if you want to reboot. It should no longer try to stop Network Manager so you should see the final reboot question when running over ssh.

The version number of the new package is securityonion-setup - 20120912-0ubuntu0securityonion90 and it has been tested by the following (thanks!):
Scott Runnels

Bro 2.2 and ELSA 1.5 packages now available

We have some new packages available for Bro 2.2 and ELSA 1.5!
ELSA 1.5 with support for Bro 2.2 and more log types
Release Notes

IMPORTANT! If you are upgrading a distributed deployment, it is vitally important that you upgrade the master before upgrading the sensors!  After upgrading the master and all sensors, if the ELSA web interface doesn't show all of your nodes properly, you may need to do the following:

  • restart autossh on each sensor:
    sudo pkill -USR1 autossh
  • stop/start (NOT restart) starman on each sensor:
    sudo service starman stop
    sudo service starman start
  • restart Apache on your master server:
    sudo service apache2 restart

If you have email configured on your sensor and you start getting lots of email from the ELSA cron job, you can fix it by changing the last line of /etc/cron.d/elsa as follows (moving 2>&1 to the end of the line):
* * * * * root perl /opt/elsa/web/cron.pl -c /etc/elsa_web.conf > /dev/null 2>&1
If you had previously installed the APT1 scripts per http://blog.securityonion.net/2013/02/seth-halls-bro-module-for-apt1-detection.html, the update will detect this and automatically enable the new version of the APT1 scripts.  If you would like to manually enable the APT1 scripts, do the following:
sudo sed -i 's|#@load apt1|@load apt1|g' /opt/bro/share/bro/site/local.bro
sudo broctl check && sudo broctl install && sudo broctl restart
The new version of Setup asks if you want to configure Bro to extract files (EXEs by default).  If you've already run Setup and want to enable file extraction, do the following:
sudo sed -i 's|#@load file-extraction|@load file-extraction|g' /opt/bro/share/bro/site/local.bro
sudo broctl check && sudo broctl install && sudo broctl restart
The new version of Setup configures Snorby to allow you to pivot from an IP address in Snorby to an ELSA query for that IP address.  If you've already run Setup and want to add this capability to Snorby, click Administration and then click Lookup Sources and add the following (also see screenshot in the Screenshots section):
https://elsa.ip.addr.ess:3154/?query_string="${ip}"%20groupby:program
