Thanks! This is getting in the right direction!

I think the mac is negotiating binary mode. I have -D dumps from login
attempts both from the mac and from other unix boxes. Hmm. I'll see if the
other boxes support -D dumps, and try logging into one of them from the
mac.

If you want, I'll send them. But I'll avoid spamming the list. :-)

This client is the one which Stanford pached to do Kerberos. It'll forward
your tickets (using kftgt I think) for you.

Plus, for 1.2, it worked with NO change to the telnet client!

Take care,
