Scan for essid corresponding to available wlan access points
In /etc/network/interfaces:
mapping <interface> script essidscan
The essidscan utility is used to tell the ifup and ifdown utilities about the current SSID of the WLAN currently being accessed. It can be used to map the SSID name to an iface stanza.
A sample /etc/network/interfaces may look like this:
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 wireless-keymode open
iface DEFAULT inet dhcp
/etc/network/interfaces
the interfaces definition file
/etc/network/run/ifstate
a record of the current state of the interfaces, managed by ifup and ifdown
