I noticed in one my classes I walked by someone with a Dell laptop and I saw he is running ethereal packet sniffer on the wireless network. Is there something I do to protect myself? I do have a shell I could use to ssh tunnel which is what I do to get on aim,msn etc since it is blocked. So I would just plug that into the socks 5 proxy in the network settings and all traffic would be encrypted right? I remember hearing dns requests would not be encrypted and there is some setting in Firefox's about:config that routes DNS through your proxy as well.
