Open an X application going through many hoops (SSH, vpn etc)
- by ??O?????
The players:
my home computer, running Linux with an X server running. (Call it HOME.)
a remote site, to which I can connect over the internet using a VPN. (SITE)
a Linux computer at the remote site, to which I can connect with ssh -X and nicely have X clients displaying on my local server. (MIDDLE)
a very old Irix machine (an Onyx) at the remote site, which has no SSH server (therefore I can't ssh -X to it), only an ssh client. (ONYX)
Purpose
I need to run an X11 application on the ONYX machine, and see the GUI on HOME. I think I stumble upon xauth issues.
So far
The current situation is:
? HOME connects to SITE
? A vncserver starts on MIDDLE:7
? vncviewer on HOME connects to vncserver on MIDDLE
? ONYX starts a forwarding ssh session to MIDDLE:
ssh -TfN -L 6007:127.0.0.1:6007 MIDDLE
? DISPLAY=localhost:7 xclient on ONYX fails with
Xlib: connection to "127.0.0.1:7.0" refused by server
I do know that the forwarding (6007:127.0.0.1:6007) succeeds.
A previous attempt was:
? HOME connects to SITE
? HOME connects to MIDDLE:
ssh -X MIDDLE (xclock displays on HOME, DISPLAY is 127.0.0.1:10)
? ONYX starts an SSH tunnel to MIDDLE:
ssh -TfN -L 6010:127.0.0.1:6010 MIDDLE
? DISPLAY=127.0.0.1:10 xclient fails with
X connection to 127.0.0.1:10.0 broken (explicit kill or server shutdown).
while an error pops up in the MIDDLE session:
X11 connection rejected because of wrong authentication.
Despair
How can I achieve my purpose?
