Network Authentication Service

This is a proprietary application from Broadcom, which is needed to provide WPA/WPA2 security on a Linux 2.4 system with broadcom-wl driver. The daemon is automatically started by fwifupdown, if security parameters are configured in /etc/network/interfaces as documented in the FreeWRT handbook.

Usage: nas [options]
        -l    LAN interface name (for network bridges)
        -i    Wireless interface name 
        -k    WPA share-key
        -m    2 - WPA
              4 - PSK
              32 - 802.1X
              64 - WPA2
              66 - WPA WPA2
              128 - PSK2
              132 - PSK PSK2             
        -g    WPA GTK rotation interval
        -h    RADIUS server IP address
        -r    RADIUS secret
        -p    RADIUS server authentication UDP port
        -s    SSID
        -w    1 - WEP
              2 - TKIP
              4 - AES
              6 - AES+TKIP
        -P    nas pid file
        -I    WEP key index
        -K    WEP share key
        -H    UDP port on which to listen to requests

The -l <lan> option must be present first and then followed by -i <wl> ... options for each wireless interface.

On "Supplicant"/"Client" side -l <lan> option can't be used.
