Pure guess on my part, but the message:
stderr: Host key verification failed.
seems to be saying that SSH is not set up properly. When you do an SSH
connection, the remote end has a file for each user called known_hosts in
the user's ssh subdirectory. E.g. ~/ssh/known_hosts on Linux. This contains
a list of DNS names or IP addresses along with the originating host's
public key (the originating host is like your desktop). Normally, the first
time you do an SSH from a desktop to a server, the SSH login process will
give a message (forget exact wording) asking you if you want to add the
host key to the known_users file. You'd normally indicate yes. Now, if
something happens and you regenerate your desktop's SSH key, the keys won't
match and SSH will abort because it thinks this is a break in attempt.
The above _might_ be your problem. If not, I'm sure one of the old wise
ones <grin/> will give the right answer.

This is a test of the Emergency Broadcast System. If this had been an
actual emergency, do you really think we'd stick around to tell you?
