VPN and exporting display

[dwsdad]

I'm trying to VPN into my office and run an X Window app here at home on my Kubuntu box. The VPN works fine, but I can't get my X app to run. I keep getting:

Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using 'xx.xx.xx.xx:0.0' as the value of the DISPLAY variable.

I did xhost + before starting the ssh session. Then I did 'setenv DISPLAY <tunnel IP address>'. Is there a security setting I need to change? BTW, I'm trying to connect to a Solaris 8 server.

I have no problem connecting from my Linux or SUN workstation at the office to the same server I'm trying from home, so I know the server is running ok.

Re: VPN and exporting display

I noticed this now when I try to ssh in:

Tunnel device open failed.
Could not request tunnel forwarding.
