wifi script

[Henk Postma]

Hi all,

I wrote a simple script to connect to the first wifi access point it finds
and thought to share it with you.

For some reason network-admin and netapplet just are slow and/or unreliable
on my laptop ... but that can also be just me.

This script requires wireless-tools and I use it on dapper

#!/bin/bash
echo "* Turning down eth0"
ifconfig eth0 down
echo "* Turning up eth1"
ifconfig eth1 up
essid=`iwlist eth1 scanning | grep ESSID | head -n 1 | awk -F: '{print $2}'`
echo "* First ESSID found = "$essid
echo "* Connecting to it"
iwconfig eth1 essid "`iwlist eth1 scanning | grep ESSID | head -n 1 | awk
-F: '{print $2}'`"
echo "* Get an IP address"
dhclient eth1
echo "* The ESSID address is now" `iwgetid`
