ssh X forwarding problem
I'm having a problem using X forwarding with ssh.
I'm logged in on machine orion and I want to ssh to machine ursa, then
use orion's X server from ursa.
i.e.
njdj@orion:~$ ssh -X ursa
[ ursa asks for password, displays startup message]
njdj@ursa: ~$ xterm &
At this point, nothiing happens for minutes, then the
following message appears:
xterm Xt error: Can't open display: localhost:10.0
Have I installed the xbase-clients package with includes xauth? yes.
(it's on both machines).
Have I put X11Forwarding yes in ursa's /etc/ssh/sshd_config? yes.
Have I put into orion's /etc/ssh/ssh_config the following:
Host *
ForwardX11 yes
- yes.
Is orion's X server listening to the socket? Yes,
and in fact if I don't try to do X forwarding
but instead set DISPLAY=orion:0.0 on ursa,
everything works.
Have I run ssh -vvv -X ursa? Yes, the output is voluminous, the last
few lines before the login message are:
debug3: tty_make_modes: 93 0
debug2: x11_get_proto /usr/bin/X11/xauth list unix:10.0 2>/dev/null
debug1: Requesting X11 forwarding with authentication spoofing.
debug1: channel request 0: x11-req
debug1: channel request 0: shell
debug1: fd 3 setting TCP_NODELAY
debug2: callback done
debug1: channel 0: open confirm rwindow 0 rmax 32768
debug2: channel 0: rcvd adjust 131072
I'm running woody, 3.0r0, on both machines.
Everything works when I try it from orion to orion,
i.e.
njdj@orion:~$ ssh -X orion
then after the login sequence, xterm & works and
DISPLAY is localhost:11.0 so forwarding from orion to orion
works. (I can't do the same test on ursa because ursa
has no display and no X server.) This suggests to
me that everything is correct on orion.
Do I need to manually copy .Xauthority data between
the two machines? I thought that was done
automatically?
Any constructive suggestions?
