Re: Xauth, how to get rid of it?
There is a nice little command called xhost which allows you to
specifiy from which machines users are allowed to run X
applications.
So this alters the Magic Cookie stuff. If you type:
xhost +mymachine
where mymachine is the hostname of the computer you are
currently typing at, then no matter what user you su to, then
you are able to run X applications. I do this when I want to
install applications when they have X installs.
First I login as username then run startx and work as normal.
If I want to run an X applicaton as another user, say root to
install a non-debianised X app, then I would type the above
command first then su to root. I can now run all the X apps I
so desire.
I also use this mechanism to read my email stored on another
machine, using netscape as my mail reader. I type:
xhost +othermachinename
rlogin othermachinename
export DISPLAY=mymachine:0.0
netscape -mail &
In order, this allows me to run and X application from another
machine using xhost.
Then I login to the other machine.
Then tell the othermachine to put the X applications display on
mymachine so I can control it.
Then I run my X application.
A word of warning though, if you do xhost + then you are
allowing anyone to run an X app on your machine, which may be
not what you desire.
Hope this all helps.
