Managing Xhost for remote systems

[amccarthy]

Hi All,
Ive recently replaced my (not at all satisfactory) Red Hat 8.0 Linux ditribution for the latest Kubuntu version. Sofar everything has worked out wonderfully: quick installation, pretty good hardware recognition, excellent reporitory handling, etc.

Nevertheless I have encountered my first problem:
As I was used to do with my previous linux, I log into a remote host (telnet) and define the corresponding export DISPLAY=X.X.X.X:0:0 on the remote machine, and type xhost Y.Y.Y.Y on the command line of the local host, but when I try to run xmgrace on the remote host I get the following message:

-Can't open display
-Failed initializing GUI, exiting

Any ideas about why this happens, and which might be the solution?

Any help or suggestions will be very much appreciatied.
Thanks.

Re: Managing Xhost for remote systems

KDM as setup by Kubuntu has listening disabled in the /etc/kde3/kdm/kdmrc file.

Find and comment out the following line:
ServerArgsLocal=-nolisten tcp

Then when you want to send something to display on your local screen you'll need to use "xhost +remote_name" (where remote_name is the name of the remote system sending the display to your workstation).
