xterm Xt error: Can't open display: %s

[David Scholz]

Hi,
I can't start X applications like xterm or others on a HP-UX server. (HP-UX Srv_1 B.11.11 U 9000/800)

I'm connecting with Telnet from a Linux (suse10.2) box to the hp-ux Srv_1 machine. Display is set with
DISPLAY=client:1.0; export DISPLAY and on the client I've done a xhost + Srv_1.

I get another error messages when I start 'xlock' or 'opc' application.
Error: Can't open display: client:1.0
Error: Couldn't find per display information


Are there any special packages I need to install on the linux box to display the CDE applications?
I've installed all QT and XT library provided from suse.

thanks

David

Hi David,

No additional packages needed that I'm aware, occasionally setting up a font-server on the unix server to serve the dt-interface fonts is required but certainly not likely in the case of xclock.

I'd suggest hostname resolution/lookup needs to be looked at here :

Try adding the FQDN's of the linux and hpux systems involved to their repsective /etc/hosts files and try again.

Also worth checking with nsllookup on both systems that they resolve each other correctly.

Tried that but no success. :(

But as always it must be an easy trick available. Any other ideas?

The resolution works fine vice versa, but I've added the hosts to each local /etc/hosts anyway. Just to give it a try..

Why ":1.0"? Why not ":0.0"? How many X
servers are you running there?

"netstat -a" on the X server, look for
listeners at ports 6000, 6001, ...?

Terminology?:
You do "xhost" on the X _server_, where the
display is. The X _client_ is where the
program runs which sends stuff to the X
server to have it displayed.
