If I know someone's ip, mac addresses and a computer name in a local wifi network, and also that there is skype running on their computer (and port), can send them a message through skype? Can I find out their skype user name?

Skype traffic travels through the Skype central servers. You cannot directly connect.

  • Then the answer is simple: you cannot find out a Skype username based on IP/mac/computername – schroeder Oct 3 '13 at 16:12
