Modifying SSH to Capture Login Credentials from Attackers

If you've ever had your SSH server dictionary attacked and wondered what
usernames / passwords the attackers were trying...

I've posted detailed instructions on modifying openssh on Ubuntu 9.04 in
order to log username / password attempts made by bots.  This information
can then be used to track down the tools / dictionaries being used against
you, and may even lead to discovery of IRC command & control channels used
by the botnet herders/masters (the topic of my next post).

Full username / password logs included for your enjoyment:

Intended for novices interested in honeypots.
