Hello,
It's been a while since I last posted a reminder about protecting
against SSH dictionary attacks.
http://lists.bitfolk.com/lurker/message/20100314.085112.f5be7da9.en.html
The problem of course has not gone away and since then there have
been many more compromises that could have been easily avoided.
So, please, if you are running sshd on port 22 and allowing password
authentication, please consider taking some steps to protect
yourself. It can very easily happen to you, and aside from the
damage it can cause to other hosts on the Internet it risks
significant downtime for your own services.
I wrote up some more info from previous discussions:

If you have further input please do feel free to add to the above
wiki article.
Cheers,
Andy
