Of course.

Messages like this often mean that the remote machine's been re-OSed recently,
and the person who did that didn't remember to save the host keys from the old
install.  If you know that the remote machine hasn't been r00ted by Evil
H4xx0rZ,[0] then the thing to do is to edit your known_hosts file, delete line
10 (the offending key), then ssh in to the remote machine again.  ssh will say
"host key fingerprint is unknown!  Accept key {1234} from $HOST?" and if you
allow that, stuff should start working again.

If you think the remote machine's been compromised, you may wish to use a
crew-served mortar on it.  Just to be sure.  :-)
