SecureCRT cannot ssh to Linux/OpenSSH

[jstraub]

I have three workstations connected via ethernet: WIN (Windows), LIN1 (Linux Mint 12) and LIN2 (SUSE Linux). Both Linux systems use OpenSSH. Using SecureCRT/ssh2 I am able to ssh to LIN2. From LIN2 I can ssh to LIN1, and from LIN1 I can ssh to LIN2.

When I try to use SecureCRT/ssh2 from WIN to LIN1 I get:

1. A long wait;
2. The New Host Key Accept Once/Accept & Save/Cancel dialog (I typically select Accept Once);
3. Another long wait;
4. A request for my password;
5. Another long wait;
6. Sometimes a timeout;
7. Sometimes a connection and command line prompt (with very slow echo).

The firewall on LIN1 is disabled. /var/log/auth.log shows only that I am connected and my password accepted. Ping from WIN to LIN1 and LIN1 to WIN is sub-millisecond. Internet access from LIN1 is fast. For a while my LIN1 sshd_config was the same as the config file on (older) LIN2 (I have since changed back to the default).

Any suggestions?

Thank you.
