mapping hotplug
script /etc/network/essidscan
map SSIDONE wlan-work
map SSIDTWO wlan-work
map HOME
iface wlan-work inet dhcp
wireless-key 1234-5678-9ABC-DEF0-1234-5678-9A
wireless-keymode restricted
iface HOME inet static
address 192.168.2.4
netmask 255.255.255.0
gateway 192.168.2.1
wireless-essid HOME
wireless-key s:somepassword
