Situation: I'm connecting to a dormitory access point that's shared with a lot of other people. When the going gets tough, I do an ARP-spoof attack on the network using an Android app called "NetCut", or
netcut on Linux.
Lately, I've noticed someone else has apparently learned how to do such an attack.
As a client, with no access to the router (but root access on my own Linux machine), how do I circumvent an ARP spoof done by someone greedy?
