Auditing a wireless access point

dws on 2003-03-18T20:53:03

Before I'm done, I will convince this bloody LinkSys (1.x) WAP11 to send SNMP traps when stations associate. I want to track if/when neighbors or drive-bys are using my access point, and to achieve minimal competency with SNMP.

Getting this far has been an education. SNMP is a subculture that I've only crossed paths with once before. It's kind of like peeling back a floorboard and discovering a new set of wires. What are they? Where do they go? What happens when I...

The IEEE 802.11 specs specify a MIB (Management Information Block) for 802.11 devices, but not traps, which seem to be vendor-specific. And googling for info suggests that the LinkSys SNMP implementation is... kinky. Browsing Net::SNMP has been educational. I'm using it now to test whether my RH8 home server box can actually receive and process traps.

Any pointers will be appreciated.

is a good place to look for MIBs.
(they're in the midst of Domain Name dispute
and have lost DNS and probably google)

can you poll the device and find the new associations?

I found a WAP11 (atmel) MIB, with what looks to be the necessary trap info, at
