Blocking unknown and not authorized devices

rprengel
Hallo,

perhaps someone has a hint.
I am managing an network 350 KM from home and  I m using arwatch to get an information about new devices.
The problem:
I m recieving tons of mails like the example.
The devices are smartphones with active wlan which try to contact the network. The network accepts only known devices via dhcp. Is there a way to block these devices?


hostname: 
          ip address: 10.54.21.4
           interface: eth0
    ethernet address: 02:0f:b5:18:1d:f9
     ethernet vendor: 
           timestamp: Friday, December 28, 2012 10:27:37 +0100

    Ralf, I think Rachpoil is referring to the 'Static Mappings' tab, but I bet you already have that filled in with the assignments.  The insight that he had to disable the SSID broadcast might be the trick you need.

    Cheers - Bob
