Re: reverse x11 tunneling versus ssh -X

Hello,
Here is the situation
Home -> Gateway -> Workstation
I normally use VNC and -L forwarding through the Gateway to
the desired workstation. This works fine, but some of my coworkers
would like to directly tunnel X11. The recipe below seems to work
fine:
home> ssh -X Gateway
Gateway> ssh -X Workstation
Workstation> xterm
This seems to work. But I would like to understand why the
following does not:
home> ssh -R 6001:127.0.0.1:6000 Gateway
Gateway> ssh Workstation
Workstation> DISPLAY=Gateway:1.0
Workstation> xterm
(Note: to generalize using port 60xx and DISPLAY=Gateway:xx.0)
Why doesn't this work?
You didn't say *how* it doesn't work (e.g. quote error messages). But
one problem could be X authentication, which SSH X forwarding handles
transparently.
