You haven't provided much to go on here, so it's unlikely you'll get
accurate answers, but here are some things you could try:
- Run ssh in debug mode ("-v -v -v") to see what it's doing. This may
give a clue where it's stuck.
- Terminate the sshd on the server side and start it up in debug mode
(also "-v -v -v") to see what it's doing. More than half the time,
hangs seen in the client are really problems on the server side.
- When a process is stuck, try running pstack on that stuck PID in a
different window. It may tell you something about what the application
is trying to do.
- Check the system logs on both the client and server. Including
error messages and complete logs with any sort of problem report is
always a good practice.
If I had to guess, I'd say that you don't have reverse DNS
(in-addr.arpa) entries for your private IP addresses, and the "hang" you
see is the lengthy delay as the sshd server attempts to resolve the
addresses back to names.
