I don't know why people keep using the super outdated ssh.el. Just use
tramp which comes with emacs. There are so many tutorials out there:

 C-x C-f /ssh:username at host: RET 

Then M-x R. 

If you setup a configuration XXX withing .ssh/config then you can simply
do C-x C-f /ssh:XXX: RET.

In the thread you refer to, I said the same thing. ssh.el is not
supported.
