A Repeating Issue

Khalid A. Al-Tayaran — Wed, 14 May 2003 18:04:46 GMT

Hi all,

This issue that I'm posting here was solved before. What changed is that is this:

I installed Redhat 9 on the machine that was RedHat 8 and managed to work run X Windows from Exceed (XDMCP). Now this isn't working in version 9. The following files were modified:
/etc/X11/xdm/xdm-config
/etc/X11/xdm/Xaccess
/etc/X11/gdm/gdm.conf
(then restarted)

netstat -a | grep xdm shows xdm is available.

telnet is working fine.

ntsysv shows that xinet is enabled.

iptables -L gives no xdm ports???

Is there something that was changed from 8 to 9 and I missed to look at it?

Appreciate your efforts,,,

When I went from Red Hat 7.2 to Red Hat 7.3 the install process overwrote my customizations to several services AND inplemented a chroot() jail on ftp without so much as warning me.

This is a common upgrade problem.

1) Go throught the files and make your changes again, they are probably gone.

2) I'm running a search here and on red hat and will get back to you.

Essentially validates your configuation methodology. My bet is Red Hat wiped out part of your work during the upgrade.

are you still using gdm and not kdm?

Because if kdm is running, you must allow XDMCP for kdm.

Hi

Thanks guys,

I was busy so I didn't update you with my situation.

I'm still stuck here...

1- I did a clean install not an upgrade

2- gdm or kdm it doesn't matter if either one is not configured right.

I need more help...

thanks///

Hello,

I'm also using Red Hat 9.0 and XDMCP works perfectly. I changed exactly the same files (Xaccess, xdm-config, gdm.conf).

Are you sure you don't have a syntax error ? please find attached my configuration files.

Good luck.

Guys,

I think I had a problem with iptables (iptables -F) .. anyway I rebuilded the system after I found gdm corrupted!!

After the rebuild everything is O.K. Now X is running fine.

I don't know really what happend to the first installation.

Thanks for your efforts,,
