ESSIDSCAN(8)

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

SYNOPSIS

     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
