Store Access-Request packet information in database

[c.schwarz at funknetz.at]

Hi,

I would like to achieve some kind of a tracking system for 802.11
wireless clients, therefore every login attempt should be accepted and
the necessary information (e.g. nas-ip-address, calling-station-id)
should be stored in an extra database table.

Example output:
rad_recv: Access-Request packet from host 192.168.30.216 port 43128,
id=5, length=200
        NAS-Port-Type = Wireless-802.11
        Calling-Station-Id = "00:1A:73:59:25:4B"
        Called-Station-Id = "hotspot1"
        NAS-Port-Id = "wlan1"
        User-Name = "christoph"
        NAS-Port = 2152726535
        Acct-Session-Id = "80500007"
        Framed-IP-Address = 10.50.0.254
        Mikrotik-Host-IP = 10.50.0.254
        CHAP-Challenge = 0x12321805f00ad380736bd946aefe0389
        CHAP-Password = 0x1153fcb1c99609b962baa8042aca266905
        Service-Type = Login-User
        WISPr-Logoff-URL = "http://10.50.0.1/logout"
        NAS-Identifier = "test-loop21"
        NAS-IP-Address = 192.168.30.216

Does anybody have an idea how to store this kind of information when
freeradius receives an access-request packet?  

Thanks in advance
Chris
