Hello guys,

Iam having issues giving users access in using x11 based programs (ie: ethereal) everytime they execute it.. it wont appear in gui.. gives a display error.

I have been trying to figure out how to do this: I tried 1 thing it was:

then i tried sudo program

still nothing

Any ideas?

Hi,
I assume, that you want start a graphical tool from the command line, and that you want to do this within a running X session, using a window manager like kde or gnome.

Can you please post the error message?

sudo is a tool to allow users running programs with other users rights. E.g., to allow a non privileged user to run the "passwd" program for root. Or something like this.

Perhaps the following is your problem:
If you want to run a graphical program as user b, but startet the X-session as user a, the X-server denies user b any access. For security.
The corresponding error message looks like:
User a can allow other users to use his X-Session with

CAUTION!!!! using the command 'xhost +' or 'xhost +all' will open X up to programs started from ANY host

This is a MAJOR security opening, and not advised (especially if you are ROOT..don't run as root...bad bad bad bad *rolls up newspaper*, don't make me use this!)

it's a much better idea to do this:
or
both commands are really the same thing
btw will close the hole again

Yes, big Ack.

Just wanted to mention the mechanism, thought that next step would be man and all deriving implications.
Sorry, pledging amendment.

Err. Just to proof my will to do better: It is generally a good idea, not to start a window manager as root.
