Debian Packages: gnome-system-tools.
The gnome-system-tools package contains a graphical interface (network-admin) to set up your network. The application is available from the standard Gnome menu as Applications-->System Tools-->Networking. You will be asked for the root password to effect changes to networking, as in Figure 60.1.
You will then see the interface that will allow you to set up your networking. With a laptop, for example, with regularly changing network configurations you can create a number of appropriate Network Profiles, with one called home chosen in Figure 60.2. To establish a connection you can click on the unselected button for the appropriate network device in the Status column of the Connections tab (after choosing the appropriate Network Profile).
