Problem logging in to ssh

[merlin]

Hi,

I can log in from a linux machine to another linux machine running sshd2
(latest 2.0.13) however when I go to log in from windows using Terraterm
Pro with ssh extentions I get an error
"This program does not understand the servers version of the protocol"
This happens no matter what cipher I set the server to.  The most obvious
was to set it to 3des as terraterm is also 3des comp.

Anyone with a similar setup have any ideas where I have gone wrong?

TIA
