How to lock a gnome panel?

Assalamualaikum wr.wb:

There are two way to change that:

1. hit Alt-F2 and run gconf-editor
    when you run it navigate to
    apps->panel->global
    under lock_down click the checkbox
    and restart gnome with Ctrl-Alt-Backspace

2.Type this, or place it on a script, and make it executable, etc...
   Code:
   gconftool-2 --type bool --set /apps/panel/global/locked_down true
   gconftool-2 --type bool --set /apps/panel/global/locked_down false
