Hi, I am trying to develop an application as follows:
I have a pc and a laptop, I want the laptop to always be listening for an incoming connection from the pc, however the pc doesn't know the laptops IP address to connect to. Is there a way for the pc to connect to any listening laptop, and once connected then check a database that I have that has a list of MAC addresses, and if the MAC address of the laptop is there then the connection stays open, otherwise it is shut???
Many thanks
