I'll second the port change approach. I started noticing all the brute force attempts in my server's logs many months ago and set up firewall rules using the 'recent' module to block an IP after 3 failed SSH connection attempts within one minute. It worked, but I still found all the log entries annoying, so I tried changing sshd to listen on a non-standard port. Since then I haven't seen a single failed login attempt in the logs, making auditing them again trivial. =09 =09 __________________________________=20 Yahoo!
