TCP Recv Question

[AdamGreenough 0]

Hey Guys,

Quick question.. I am connecting two computers over the internet, computer 'A' would listen and computer 'B' would connect to it. Can computer 'B' use TCPRecv and receive data from computer 'A' on the Connected socket or would we have to do a side by side relay and make both of them listen and both of them connect to one another and receiving data locally?

Thanks in Advance

Both computers would be both Server and Client. The two connections, one in each direction, are separate.

I was creating a simple chat application some times ago but I left it in the middle... however I'll return to it someday!

The concept here is that you will use the same script in both computers. This script will have both, the Receiver function and the Sender function.

-When you start you application on (A), it will try to connect to (B ) and if it can't, then it will stay listening in a certain port...

-The same way, you start now the program on (B ) and it will try to connect, and since (A) is already listening, it will connect!

Hope this helps you clarifying

regards

@ALTIN,

Yes this helps very much but what about the port forwarding feature.. wouldnt you have to port forward both computers? im thinking more something along the lines like what AVG does, im sure not every software that connected to a remote server has to have a port forwarded does it? or would it be using the standard internet port 80 which always seems to be routed
