NAME
       essidscan - scan for ESSID corresponding to available WLAN access points


SYNOPSIS
       In /etc/network/interfaces:

       mapping <interface> script essidscan


DESCRIPTION
       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.


CONFIGURATION
       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
