Hi,
I want to communicate between a client and a server, with the server sitting on a box at another site, over the internet.
Do sockets do this? I've never done this before over the net, only between two PC's on the same LAN.
Thanks

So long as you have a server running and you know either the DNS name or IP address and port where the service is located, it makes no difference whether the two communicating machines are on the same physical LAN or half a world away.

Hi,
Socket connection can be made to any PC on the network . But as on internet due to firewalls which actually protects the system from external hacking will prevent you to make a socket connection. so as long as firewall allows we can connect to any system.
thanks
