You'd be surprised the fun which goes on at conferences such as RIPE and IETF when WaveLAN virgins get onto the network and realise it isn't secure. You might have heard of a guy called Randy Bush, whose favourite party trick at such events is to sniff the WaveLAN, and email out to captured POP3 usernames their own password with the message 'Be careful with radio!'. It's not even a switched network as a default install. Setting up some sort of VPN using PoPToP isn't a bad idea in such cases, although WaveLAN does have some security built into it. Personally I use the Buffalo Technology kit which seems to work for 'doze, BSD and Linux. I've heard rumours that if you wander through Stockholm's business district or through the Square Mile in London, if you're in promiscuous mode you can pick up all sorts of transmissions and a large number of DHCP servers offering IPs to anyone who gets the ESS ID right. Hope this helps someone. Just be careful out there ;) Back to the Index
