[cobalt-security] sshd security tweaking

["Rodrego Alverez" <rodalverez@xxxxxxxx>]

We seems to be among the many whose Cobalt RaQ4 has been hacked through the SSH exploit. 
After a complete re-installation, we have secured the box a bit better this time (self-issued certificate for Cobalt admin interface, upgrade to OpenSSH 3.1 and such). 

Since I, as server admin, am the only person needing shell access, I was thinking of changing the port to which sshd listens to something more obscure, rather than the default 22. Does this help? 

Would it be done in the /etc/ssh/sshd_config file? It seems that every line in that file is commented out in the version of ssh I downloaded from http://pkgmaster.com/. 

I have uncommented the line to stop direct root login myself.  I also uncommented the line listing just Protocal 2, but that caused an error when I tried logging in.  Should I still attempt to turn off acceptance of SSH1 as well? 

Is this all done in the same config file? 

Thanks for advice! 
Rod.
