OpenSSH_3.0.1p1 disconnects due to bad packet length and corrupted MAC on input.

[Daniel Bergman]

Hi

I'm having huge problems with OpenSSH 3.0.1p1, compiled with OpenSSL 0.9.6b 9 Jul 2001 and running with prngd_0.9.23, it disconnects unexpectedly during client session due to bad packet length and corrupted MAC on input, according to debug anyway.

What can cause this kinds of errors? I've verified that both se9104/server and switch runs in 100 Mbit full duplex and switch statstictics show no collisions at all.

I've attached output of several 'ssh -v -v -v se9104' commands that fails with either "Disconnecting: Bad packet length" or "Corrupted MAC on input". I've also attached client ssh config, server sshd config and server process list.

Regards,
Daniel
