openssh unix dev - Jun 2002 - NEW: Urgent: OpenSSH_3.0.1p1 disconnects due to bad packet length and corrupted MAC on input.

NEW message w/ URL to zip archive containing debug output.

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 corruped 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 created a zip archive containing output of several 'ssh -v -v -v
se9104' commands that fails with either "Disconnecting: Bad packet
length" or "Corrupted MAC on input", client ssh config, server
sshd config and server process list.

You can download the archive from
