http://unix.stackexchange.com – I have a local network set up using a wireless tether through my android phone. Many computers connect to it and all i can see is there ip address/mac address. What i want to do is basically get a physical name of the computer or 'hack' (or ssh or something similar) into the computer using the ip address. Any suggestions? (HowTos)
