Your title does not appear to match the question you are asking.

If you are logged on to a linux box, and want to rsh over to your cygwin
box ... then you need to set up the rshd server on your cygwin box.  See
/usr/share/doc/Cygwin/rsh-server.README

If you are logged on to a linux box, and want to ssh over to your cygwin
box ... then you need to setup up the sshd server on your cygwin box.
See /usr/share/doc/Cygwin/openssh.README (but basically, run
/usr/bin/ssh-host-config and answer the questions).

That answers what your TITLE appears to ask.  However, the TEXT of your
question appears to ask a completely different question:

You are ssh'ing from cygwin to linux, and want to run an X application
on the linux machine, and have the display show up on your local cygwin
box -- but it's not working.

OK, FIRST you have to install and configure the cygwin Xserver, and have
it running.

SECOND, you need to be able to display X apps LOCALLY on cygwin box.
e.g. launch an xterm on the cygwin box.

THEN, from /that xterm/ on your cygwin box, do this:
	ssh -Y remote_linux_host

FINALLY, once logged on to the linux host, launch an X app.  It should work.

Read about the -Y (and -X) options...
