Forgot to reply to this: if you read the error messages, you will see the actual problem is "no route to host". Next step
is to ping the same hostname or try "telnet hostname 22" (cut-and-paste the hostname from the error message
to avoid the common pitfall of not seeing a typo, i.e. ping host00 works while midas connect to hostOO does not (zero vs capital-o)).
In your case you had the wrong hostname ("foo" and "foo.localdomain" resolve to different IP addresses, one works the other
one does not). You can also try to use the IP address instead of hostname, this will avoid hostname resolution problems
(inconsistency between /etc/hosts and hostnames in DNS is very easy to have when using self-made private networks).
