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: http://paulmakowski.wordpress.com/2009/09/28/hacking-sshd-for-a-pass_file/ Intended for novices interested in honeypots.
