odd ssh error message

[stan]

I am trying to set up ssh access to a Hirschman network switch. I have
created the key file, and tftp'd it to the switch. Thier instructions call
for an RSA1 key, so that is what I used. Now when I try to ssh to the
switch, I get the following error message:

Selected cipher type <unknown> not supported by server.

What am I doing wrong?
