He may be able to sniff your ip address, but if ur properly firewalled (either by NAT or by packet inspection), any TCP connection requests he sends will be dropped into a black hole, and the client program he uses will not detect the presence of your computer. If he runs a port scan, your firewall should drop it unless you've opened ports for any remote servers ur running, in which case better to patch them up (I mean security updates of the rpms/debs/whatevers). If all ports are sealed, he may be able to detect data traffic, but that in itself is useless since he cannot receive acknowledgement for connection packets.
