Ubuntu:ifscheme

From Linux 101, The beginner's guide to all things Linux.

ifscheme is a program you can use to easily enable switching between different networks. For example, you might go to school to use Clemson's wireless then go home to a different wireless network.

sudo apt-get install ifscheme

sudo $editor /etc/network/interfaces

Add the following:

mapping $interface
     script /usr/sbin/ifscheme-mapping

iface $interface-clemson
     wireless-essid cuairnet
     wireless-key open $wep_key

iface $interface-home
     wireless-essid home

$editor 

whatever text editor you prefer (use nano if you don't know of any others)

$interface 

the wireless interface (run iwconfig to see)

$wep_key 

Clemson's WEP key

To use the clemson profile:

sudo ifscheme clemson

or whatever you name your profiles.

Then just ifup as you normally would. If you decide to use the home profile, ifdown the interface first then use ifscheme to switch to home. You can name the profile anything you wish just by appending it to "$iface-".
