Re: ssh/X with two hops

["Thomas Chadwick" <j_tetazoo at hotmail dot com>]

BTW - emacs works perfectly well over a terminal session.  No need for X at 
all.  You should be able to open a good-old MS-DOS prompt, telnet or ssh to 
your hearts content, then make sure TERM=vt100 on the remote system, then 
run emacs.
