Re: Remote ssh -Y display: cannot create graphics configuration

Hi Michael,

BTW - ssh -Y and -X are nearly the same thing, though I think the -X is a bit more robust.

from the man page:

-X Enables X11 forwarding. This can also be specified on a per-
host basis in a configuration file.

X11 forwarding should be enabled with caution. Users with the
ability to bypass file permissions on the remote host (for the
user’s X authorization database) can access the local X11 dis-
play through the forwarded connection. An attacker may then be
able to perform activities such as keystroke monitoring.

-x Disables X11 forwarding.

-Y Enables trusted X11 forwarding.

The error you are getting seems to indicate that your versions of Java3D aren't playing nicely with each other (between your local machine and your remote SPARC machine which is running the IDV, if I understand you correctly).

I wish I could be more helpful, but I'm still trying to figure out which graphics controllers are being used when using the ssh -Y or -X options and which Java(2/3)D (local/remote) takes care of mouse inputs.

I wonder if anyone has seen this problem? I checked the archives

IDV runs fine on my Linux box (Fedora core 3) with a low end video card
(ASUS Radeon 9200 SE 128MB AGP8X).

I can also "ssh -Y" from my Linux box back to itself, and IDV runs fine.
Note, if I use "ssh -X", IDV complains about GLX extensions not being
available, but "ssh -Y" works okay.

Now, on a remote SunOS SPARC server (headless, but with OpenGL installed),
I have installed the Solaris SPARC IDV.

When I "ssh -Y" from my Linux box to that remote box, and then run runIDV, I get a popup error saying that it cannot create a graphics configuration.
Here is what it prints out:

> ./runIDV -debug -trace

Java 3D WARNING : reported GLX version = 1.2
GLX version 1.3 or higher is required
The reported version number may be incorrect. There is a known
ATI driver bug in glXQueryVersion that incorrectly reports the GLX
version as 1.2 when it really is 1.3, so Java 3D will attempt to
run anyway.

Note, I see that same GLX warning when I run locally.

I opened my firewall up completely and still see the same problem.

I am not sure where to look next. Any pointers would be much appreciated.

Thank you in advance,

Michael Zeleznik
