client server application using php [closed]

Question

I just wondered if anyone could render an assistance to me in what I am trying to achieve. I am trying to apply php to do the below coding if you could help. And if any other server side scripting language could do the task would be appreciated.

Lets say : you have C1 and C2 and you have Server between them right, My goal is to get C1 and c2 know each others IP, so C1 connects to server, and server stores c1's IP, in a text file or other place, and C2 connect to server, and server also stores his info, and then both c1 and c2 dowload the tex file, and use the info on it.

Answer 1

Whatever you want to achieve, you are better off using a dynamic DNS service like dyndns.org.

You can use them to register your IP with a real hostname like myhost1.dyndns.org for C1 and myhost2.dyndns.org for C2 and both systems only need to know this static information.
