Ours is a somewhat lower-tech approach than some listed here. We enter the MACs into dhcp to receive special addresses. Then What's Up pages me when those addresses show up again. Then I can go and start walking the system for locations. We've successfully retrieved a couple, but the majority of laptops that go walkies never reappear on our network. Once in a while we see one show up for a couple of minutes only and vanish again; typically around our AP's that are visible from downtown restaurants. I've never had those on the air long enough to send Security over to have a look, unfortunately. -- Regards, -- Cal Frye, Network Administrator, Oberlin College Mudd Library, x.56930 -- CIT will NEVER ask you for your password! www.calfrye.com, www.pitalabs.com "Accomplishments have no color. --Leontyne Price. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
