Incompatibility with free version

[Hasan Diwan]

	First off, I am not a subscriber, so please CC replies to my
email address. The problem I am having -- I do not know who is to blame,
but am just covering all angles. I run OpenSSH 2.1.1 on FreeBSD. When I
try to connect to a server running ssh2d from ftp.ssh.com, it fails
saying corrupted MAC on input. I am including a log of my connection
below:
