You probably need to set the display; although, I haven't tried this
going through a 'middle tier'.
From the 'client':
xhost <host name>
xhost <middle tier name>
From the 'host'
export DISPLAY=3D<client name>:0.0
Then test the xclock.
I tried it out, and it worked.=20

Subject: ssh chaining?
I'm trying to do X windows thru a 'chain' of ssh logins...
Me -> ssh box1 -> ssh box2
Is this doable?
I ssh into box1, and then from box1 I ssh into box2. I actually want to
be doing X work in box2, using my laptop as a X11 'terminal' at kaladi
bros. In, say, Hawaii....
As you may have guessed tho, it doesn't work. Here's the error:
Error: Can't open display:
My laptop has Xfree on it (gentoo)
Box1 is an openbsd box that does not have X on it. I can ssh into box1
just fine.
I can ssh into box2 just fine. It has X on it. But typing xclock&
gives the "error: can't open display:". No display number
Here's the box1 sshd_config:
Port 22
Protocol 2
AllowTCPForwarding yes
X11Forwarding yes
GatewayPorts yes
Box1 ssh_config:
Host *
ForwardX11 yes
Protocol 2
Port 22
ForwardAgent yes
box2 sshd_config:
Port 22
Protocol 2
AllowTCPForwarding yes
X11Forwarding yes
GatewayPorts yes
Box2 ssh_config:
Host *
ForwardX11 yes
Protocol 2
Port 22
ForwardAgent yes
What am I missing?
Thx,
Lee
