Security Onion 20120418 now available!

Security Onion 20120418 is now available!  This resolves the following issue:
Issue 254: tcpflow 1.1.1 connection counter breaks Sguil's transcript window

Notes
This update installs the new tcpflow 1.2.6 at /usr/local/bin/tcpflow and a shim at /usr/bin/tcpflow.  The shim is just a bash script that runs the following:

/usr/local/bin/tcpflow -T%A.%a-%B.%b $@

The new version of tcpflow has a new output format so we execute the shim to call tcpflow with the correct -T options to produce the original tcpflow format that Sguil is expecting.

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.
