openssh unix dev - Mar 2001 - X forwarding from Linux -> Irix not working

I'm logging in from an irix machine to a linux machine (both running
openssh-2.5.1p2) and am unable to run any X applications.

I ran a verbose session and this happens:

debug: fd 6 IS O_NONBLOCK
debug: channel 0: new [X11 connection from host port 4572]
debug: X11 connection uses different authentication protocol.
debug: X11 rejected 0 i1/o16
debug: channel 0: read failed
debug: channel 0: input open -> drain
debug: channel 0: close_read
debug: channel 0: input: no drain shortcut
debug: channel 0: ibuf empty
debug: channel 0: input drain -> wait_oclose
debug: channel 0: send ieof
debug: channel 0: write failed
debug: channel 0: output open -> wait_ieof
debug: channel 0: send oclose
debug: channel 0: close_write
debug: X11 closed 0 i4/o64
debug: channel 0: rcvd ieof
debug: channel 0: non-open
channel 0: istate 4 != open
channel 0: ostate 64 != open
debug: channel 0: rcvd oclose
debug: channel 0: input wait_oclose -> closed
X connection to pc07:10.0 broken (explicit kill or server shutdown).


X forwarding is configured for both the servers and clients on both
systems...and they have access through tcpwrappers for forwarding.

Also, the X forwarding works when ssh'ing from the Linux machine to the
Irix machine.

i'm on indy r5000 running 6.5.9m connecting to a redhat 6.2
both running openssh-2.5.1p2, no tcp wrappers and am 
experiencing no problems either way.

i'd be happy to test anything you like.

I had this the other way around. Turned out that xauth was not being run
properly from sshd because /etc/ssh/sshrc existed and was not running
xauth. After you login you can use "xauth\nlist" and it should have a
couple of entries and be using an authority file /tmp/ssh-xxxx/cookies.
The path to xauth is set by the configure script but can be overridden in
sshd_config.
