Try using the --P flag to select a non-priviledged port above 1023 to send on. Since
the ssh server will send it's traffic back to you on the port you came in from, it may
be that the firewall there is dropping packets.
Also, can you telnet to the host on 22? I usually see a message about what ssh
version is in use on port 22, when I try to telnet to it. ex:
telnet ag 22
Trying 131.45.25.4...
Connected to [EMAIL PROTECTED]
Escape character is '^]'.
SSH-2.0-2.0.13 (non-commercial)
That might help you determine if port 22 is open on the hosts firewall or router.
I've also used tcpdump to watch and see if packets are being sent back by the host.

Hi Hiranya,
There could be a hundred reasons for this. Are you going through a
gateway or a firewall? Are they using SSH1 or SSH2 on the remote host?
Try SSHing to yourself like this:
$ ssh localhost
If that works then something on the other end is not letting you in. Port
22 could be blocked for some reason.
