Re: Wireless access point association daemon?

["Jeremy T. Bouse" <jbouse@debian.org>]

	For using my Cisco Aironet 350 on my Sony Vaio laptop that goes
between several WiFi networks using WEP I just created a script that I
use in /etc/network/interfaces that handles the mapping for me... The
script basically scans the network and tries to match an ESSID it finds
from scanning to a mapping config line...

	What I end up with in the interfaces file is along the lines of:

mapping eth1 wifi0
	script /path/to/get-essid.sh
	map ESSID-Office wifi-office
	map ESSID-Home wifi-home

iface wifi-home inet dhcp
	wireless_mode managed
	wireless_esside ESSID-Home
	wireless_key <10 or 26 hexadecimal key>
	wireless_enc on

iface wifi-office inet dhcp
	wireless_mode managed
	wireless_esside ESSID-Home
	wireless_key <10 or 26 hexadecimal key>
	wireless_enc on

	I am not writing this from the laptop at the moment so I don't
have the get-essid.sh script handy but if there is interest I'll try to
get it posted later...

	Regards,
	Jeremy
