Hello guys , I am very new in socket programming using php. Is it possible to swap a client ip and port ? This is what I am trying to do.
Let say you have Comp1 and Comp2
and you have Server between them.
My goal is to get Comp1 and Comp2 know each others IP
so Comp1 connects to server
and server stores comp1's IP
in a text file or other place
and Comp2 connect to server
and server also stores his info
and then both comp1 and comp2 dowload the tex file
and use the info on it.

Please I would appreciate any supportive suggestions.
Thanks in advanced.

Yes you can do it !!
Run the client program in comp1 and comp2 and server program on Server .

In your server program you can open a file and save the client ip address and port number.

Now,
You can ask the content of this file as a network packet from the server to the compX system and take action after parsing the packet info.
Or
You can download the text file via tftp or ftp protocol and use the data stored in it for your use.

Note: You need to handle the data carefully applying the sanity checks to be sure about the integrity of the data .

Hope this helps !!
