OpenSSH vs ssh.com

[Rob Hagopian]

openssh-snap-20001204 vs F-SECURE SSH Version 2.0.12 (from BigIP v3.3)
doesn't work for protocol 2 (but is fine for protocol 1), any ideas what
would cause this? Below are full debug outputs. In addition, the prior
snapshot I had on the machine caused the following output in the sshd on
the BigIP machine:

Dec  4 03:18:44 b1abv sshd[144]: connection from "10.30.12.11"
Dec  4 03:18:44 b1abv sshd[15841]: DNS lookup failed for "10.30.12.11".
Dec  4 03:18:45 b1abv sshd[15841]: got bad packet when verifying user
					root's publickey.
Dec  4 03:18:45 b1abv sshd[15841]: Remote host disconnected: Connection
					closed.
Dec  4 03:18:45 b1abv sshd[15841]: connection lost: 'Connection closed.'

sshd -v output:
