Hello

We are using a x-terminal software (x-winpro) to work with xwindow on Solaris servers without any specific setting. (after installation).

I have tried to do the same thing with RedHat-AS4 and Suse-10 but neither is able to work with x-winpro.

1- What settings do I need to do on Redhat or Suse servers to be able to use their x-window remotely? (except vncserver etc.)

2- So I need a specific x-terminal software for linux? (or specific settings on x-winpro will work)?

By default, Linux distributions don't permit remote access to X. You need to explicitly enable XDMCP remote access for the display manager, and then configure the system firewall to permit access to those ports. Perhaps your older Solaris systems didn't have these features?

The default display manager for RH is GDM, and you can enable remote XDMCP access with the graphical utility (System > Login Screen), as well as by manually editing the (well-commented) gdm.conf file.

For the firewall, allow UDP 177 for browsing to work, and a TCP port range from 6000 up to the maximum number of displays.

SUSE may use KDM instead of GDM, but I'm not sure about that.

Thank you very much.

I was able to activate redhat AS (edited gdm.conf file as you told) but SUSE does not work though I have configured 4 different files (xdm, fs, Xaccess, ...)

I'm fairly sure that SUSE uses KDM, which has it's own config file. There may also be some global option lurking in a file in /etc/sysconfig (or the SUSE equivalent).

Sorry to be so vague - I very rarely use SUSE.

If you just need to use individual X apps, you should instead just use SSH's X forwarding.
