These messages make sense. You close up your connection, so sshd(8)
eventually gives up and quits.
I guess the only question is, why doesn't the connection start up? Why
is it hanging long enough for you to get impatient and close up
SecureCRT? How long are you giving it? Let it sit for at least a
minute or two in case there are some DNS problems. Also, you might
want to sniff the connection (tcpdump(8)) to watch the connection
establish (and watch for the DNS traffic too). Finally, review the
firewall logs to make sure something weird isn't happening there.
