Indeed, fail2ban blocks the scanning ipadress after a specified number. = What you could also do is setup something like portknocking. If a = pre-defined sequence of ports are 'scanned', a script can be called = which opens port22... For more info on portknocking, see http://portknocking.sourceforge.net/ = or http://www.portknocking.org/ rgrds, Marco Jurriaans -----Original Message----- From: Jarrod Frates [mailto:jfrates.ml () gmail com] Sent: Mon 5-6-2006 17:56 To: pen-test () securityfocus com Subject: Re: Re: Some new SSH exploit script?

I strongly disagree with changing the port sshd listens on to "solve"
this attack. It is completely unnecessary. I've found some success with Fail2Ban, which adds in iptables rules after a specified number of bad attempts, and I monitor the reports for repetitive IP addresses or blocks, adding them to a permanent ban list. The number of failures per day decreased from 20K+ to under 50.
