Is there any way to temporarily "switch off (and back on)" the internet connection on a system (that runs linux)? The following methods are not allowed:
Turning off the router. That would lead to a lot of angry young individuals. This method must be particular to my workstation.
Use root privileges (coz I do not have them).
Yank the ethernet cable from the system.
Why: Sometimes the internet proves to be a distraction.
I am using the following system: Fedora release 11 (Leonidas), linux kernel 2.6.30 and GNOME 2.26.3
