in centos, worked. Thanks.

from root user's gnome-desktop's terminal window, i had to do this:

sudo -u ff -H xhost 127.0.0.1

sudo -u ff -H firefox



how can i run firefox, xchat, etc multiple internet applications by using a same non root username (for example, username: 'InternetApps') ?

Give a man a fish; you have fed him for today. Teach a man to fish, and he will never come back to church. (works in Africa)
Nice. Not as safe as "chrooting" firefox but should work.
"xhost 127.0.0.1" or "xhost localhost" didn't work for me on Debian stable (lenny). "xhost local:" did.
I copied the "/usr/bin/firefox" script, then renamed that(copy) to "/usr/bin/firefox-InternetApps".

Using the visudo, add this '/usr/bin/firefox-InternetApps' into the NOPASSWD line.

If someone wants to further modify the 'firefox-InternetApps' script, then they can do so.

Now create a Firefox Profile inside firefox for 'InternetApps' user :

sudo -u InternetApps -H firefox-InternetApps -profilemanager -no-remote &

A window will appear, to allow you to add new Profile(s), create 'InternetApps'.

Start firefox & then exit from it.

Now following command will start firefox & take us inside the 'InternetApps' profile :

sudo -u InternetApps -H firefox-InternetApps -p InternetApps -no-remote &

I copied the "/usr/bin/firefox" script (not a link) file, then renamed that (copied) file to "firefox-ia", open "firefox-ia" with a text editor, keep only the top two lines, delete all other lines, then add our commandline, it should look like this:

#!/bin/sh

#

sudo -u InternetApps -H firefox-InternetApps -p InternetApps -no-remote &

# end of file

Then simply type : "firefox-ia" , (without the quote symbols,) to run firefox (under a non root user and with a different firefox profile).

... This process worked on centos 5.6 firefox 3.6.17. ~ Bry8Star.

try using kdesu instead of su, it'll work without any of the other hacks, plus allowing anyone on 127.1 to connect to X isnt secure
wow...the second works fine!!!

How do i call the method, say i already have "double Weight" computed and need to be aproximated to two decimal places and it appears in different functions...

Teach a man to fish and he will quit work.
Teach your wife to work and fish. Then you can sit on the river bank drink beer and watch her catch the big one.
Teach a man to fish and he will buy up all the places to fish depriving his fellow fishermen the opportunity to fish for themselves, unless you go to work for them. (Walmart)
You don't need sudo rights and you don't have to edit sudoers file to archieve this now.

(Maybe this is easier in 2020. I tried in ~2012 to make this work, but without succes)

Now you need to add this line to "ff":s .bashrc

export DISPLAY=:0.0

and run as your normal user this:

xhost +local:

then just write: su ff

and then when you have a terminal as ff, you can start firefox or any other program, by:

firefox
