Security Onion 20110122 fixes DNS error in Sguil

I received Issue 77 in the Security Onion Issue Tracker.  The Issue describes an error when enabling Reverse DNS queries in Sguil.  I was able to duplicate the issue.

I consulted with Bamm Visscher and he said this was due to Ubuntu's libudp-tcl package.  I removed libudp-tcl and Reverse DNS queries started working again.

I've released a new upgrade script that fixes this issue automatically.  Just download from and run it like so:
sudo bash

It will then upgrade your Security Onion installation to version 20110122 and Reverse DNS queries should start working correctly.
