Re: can't ssh or telnet to Debian box

["Owen G. Emry" <owen@loshwomp.com>]

Some more information:

Since apache works perfectly, I stopped it and tried moving telnet to port 
80.  Still no connection.  ssh didn't work over port 80, either, so I know 
it's not a firewall problem.

After scouring the net, I read that sometimes having ipv6 enabled in the 
kernel will confuse ssh, so I tried running sshd -4 to bind only to ipv4 
addresses...  still nothing.

Are there any other reasons two basically identical boxes won't ssh to each 
other?

Again, I very much appreciate any suggestions.
