How can you control the other laptop from your laptop?

I think it's this program caled "ghost control" or something. Probably not legal though, so heed my warning.
you have many methods to do this. telnet, is one. but you have to be connected to internet and that computer should be accessible to you through a server or a gateway. but do not try anything like that 'cause it is illegal. you even need to know the ip address.

Its not illegal if you are doing it to your own computer or if you have permission from the user
