That error message sounds like one Microsoft would issue - really
verbose but not very precise. But since Windows doesn't supply an ssh
client, it can't be that. What ssh client are you using?
If by 'unreachable' that message means the errno ENETUNREACH or
EHOSTUNREACH, then you have a routing problem. I doubt that message is
that precise, though.
If you have access to another ssh client, try that. You may get better
diagnostics from a different client.
Or if you have access to a UNIX machine, try connecting to the ssh port
on that server using telnet (ie, 'telnet ftp.XXXX.com 22'). Every UNIX
version of telnet I have ever used gave good error messages that you
can tie back to a specific socket error number. You can tell a lot
from those errnos. Don't use the Windows telnet. It has lousy error
PS - If you happen to get connected, with telnet just type the telnet
escape character to disconnect.
