X forwarding from Linux -> Irix not working

[Kevin Taylor]

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

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.
