hi beerstein,
ssh and mc work fine for me.
perhaps the reason for your problems are different user-names, user ids or a even a different port for the ssh-sever.
on tinycore the common user is tc and ssh has port 22.
if f.e. the user on the server is sam and the sshserver offers the port 22222,
then following command works in mc.
choose shell link in the menue and then enter:
sam@192.168.0.14:22222
then after the password-request and entering the password the link is connected for you.
i guesss your problem is a different user or his user id,
cause it's possible to have the user sam with user id 1000,
or another user sam with the user id 500.
some distribution start with the first user with user id 1000, others with user id 500.
the user tc has the user id 1001.
the other way is to build a ssh tunnel over localhost and a connection over this specific localhost port.
