You simply run them on that computer; you can always configure the sockets so that they listen on the 'loopback' interface (127.0.0.1) - you can do that by specifying 127.0.0.1 explicitly or by setting the socket to listen on all interfaces (0.0.0.0).

It is common for client/server programs to run on a single machine - like the X server and client, database servers, http servers ... so it's a very normal thing to do.

1.Open a shell. Run server
2.Open another shell run client.connect to 127.0.0.1.Give the port number either as an argument or in the program.

Make sure you run the server program first and only then client could run.

thanks dudes ... actually i am new to linux and socket programming, so thats y
my problem was solved, infact i have only to give the ip address (loopback) after the client and server programs.

can any body recomend me a good website/tutorial or book about socket programming from absolutely beginning.

i am studying beej guide, take the concept how server and client communicate with each other but didnt understand the code.

See 'Beginning Linux Programing' by Wrox publishers.I think their url is www.wrox.com.The book is not about socket programming,but has a chapter on socket programming with detailed explanation of code.You can buy the book or download the code from their site.search for 'Beginning Linux Programming'.They have a 'Beginning' series of books.

Thanks.
