...
| If a host has more than one network adapter, how do i know which IP should 
| i put inside  the PONG package? 
| Specifically, when dealing with dial-up users who are also connected to a 
| LAN, gethostbyname(gethostname()) always returns their internal adress.

If you have a connected socket s, s.getsockname() will return the
IP address and port number of the local endpoint.
