Segmentation Fault with RH 5.3 & X11 Tunneling

[lomcevak]

Greetings,

I just started to install Red Hat 5.3 and I'm running into problems with X11 tunneling. Normally I log onto a RH server from my PC via SSH with X11 tunneling enabled. Then I'll run app.s like /usr/bin/system-config-users and it runs fine. Now when I try to run the same app on 5.3 it's giving me 'Segmentation Fault' errors and the app aborts. Not just system-config-users but all app.s.

Am I missing something here? The PC is Windows XP and the X11 emulator is eXcursion. All updates have been downloaded and applied.

Hi

Segmentation Fault, that's bad! very bad

Is it only with X11 forwarding over SSH?

What happends when you execute something without X11 forwarding such as "ls", "top", or "ps"?

What happends if you execute both graphical and text applications directly on the RHEL 5.3?

Have you compared the versions on both RHEL systems for OpenSSH and X server?


Best!

Oops, I should have said all GUI app.s abort with 'Segmentation Fault'. All text app.s like ls, top, and ps run fine.

The GUI app.s run fine when run on the graphical console.

The SSH version on RH4 is OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003
The SSH version of RH5 is OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

I haven't encountered this problem myself so unless anyone on this forum did, I would suggest first of all a down grade of both openSSH and openSSL to the same version as on the RHEL 4 box just for the sake of troubleshooting.

How about X? same version on both machines?

Best!

Not sure how to check version of X. How do you do that?

Thanks.

To check the X version:

cat /var/log/Xorg.0.log | head -2

You can see the version of X at the beginning of the Xorg.0.log file.

Hope that helps.
