You're seeing two unrelated symptoms: the "No xauth data" message, and the
"DISPLAY is not set" problem.  The former is just a warning you get from
ssh -- Googling for it produces a bunch of descriptions and fix recipes
(in fact, someone posted one to this list earlier this year).

The latter is actually your problem.  It could be that the X forwarding is
disabled on the server.  Try "ssh -Y -vvv", and see what it gives you...
