Aren't all auth failures stored in /var/log/auth (or something similar)? and won't most log-watching and reporting packages report failed login attempts already? ~k On Tue, 2009-09-29 at 12:25 -0700, my.hndl wrote:
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).
