You can always use a radius server to authentificate the users and it will give you who is connected to the network. The most obvious option for this is Freeradius, it's a little complicate to make it run but it's very useful further. Another option is using ntop, that can show you the machines connected to the network. -- Jose Maria Lopez Hernandez Director Tecnico de bgSEC jkerouac@xxxxxxxxx bgSEC Seguridad y Consultoria de Sistemas Informaticos http://www.bgsec.com ESPAÃA The only people for me are the mad ones -- the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow Roman candles. -- Jack Kerouac, "On the Road"
