Xlib: connection to ":0.0" refused by server [Solved]

[philip]

I have installed a CAD program (ProE). It has a startscript:

/usr/local/ptc/proe_startscript

When I run the startscript as root, the program starts fine. But if I run the startscript as user I get the following error message

You can add a user to the X server access list. Run as <username>

Hi Mike,

Are you shure I should not run this command as root?

I did as you recommended but get:

I ran it as root and then it worked;

It should be noted that opening up the xserver with xhost+ does have some level of security risk to it, although it is smaller when specifying xhost+ with a username, as mentioned above. I would recommend firewalling off port 6000 if you plan to use this often and for extended periods of time, especially if you are working on an open network.

Thanks for the advice, I will firewall port 6000.

I am still curious why I need to open up the xserver with xhost+ for this particular application and no other applications? The specific circumstans is that I installed this application manually, i.e. it is not part of the Portage tree. But I have installed other applications manually, without this happening.

toralf,
I always log in as "user myslef", i.e. not as root. I installed the program manually as root, i.e su root before installing. When I ran the program as root the X problem did not show. But it was when I wanted to launch the program from a "user myself" termianal that the problem arose. Maybe I should have installed the program as "user myself"? But that is not customary, is it?

widreman,
Is there any way to determine if X listens to TCP?

Mike,

There is no info about user, maybe becasue I use to do su root before I manage my system.

If I stay as user (philip) and do $ ps -efla | grep nolisten

then I get;
