TCP/IP Programming in C

Socket Programming:
-Minimum Requirement.
-Linux OS [Lib. Header Files]
-IP & Port No.
-Server & Client Concept.
-Major steps.
-Server:
=Create a socket with the socket()
=Bind the socket to an address using the bind().
=Listen for connections with the listen().
=Accept a connection with the accept().
=Send and receive data, use the read() and write() system calls.

-Client:
=Create a socket with the socket()
=Connect the socket to the address of the server using the connect() system call.
=Send and receive data, use the read() and write() system calls.
-Server coding.

Thank you Prof. Vinod Pillai, This was such a great tutorial, I appreciate your help. Very useful. I hope that you can put more tutorials!

Simple solution is you consider that you want to transfer the content of the file from client to server/reverse or consider like open the file and read the data and send data to server.

First of all, Thanks for the tutorial

client.c:45:22: error: dereferencing pointer to incomplete type
client.c:45:72: error: dereferencing pointer to incomplete type 

the code in 45th line is 
bcopy((char *)server->h_addr, (char *)&serv_addr.sin_addr.s_addr, server->h_length);

How do i resolve it...

Cannot do socket programming on windows? Having written many network programs on windows, I think I'm fair in saying you're wrong professor.

Hello Prof Vinod, i wanted some personal help to write a socks program to connect a client to a server and cache the web pages the client often visits

Why is the source code provided in the webpage different from the one you have in the video

I am interested in socket programming . I want to do my final year project on that . Where should i start from, any suggestions ? i mean any Books? e-books? what are the programming languages i should know? what are the pre-requisites for to learn socket programming ?

[devanshigariba]

if i add a while(1) loop in tcp, just the way it is done for udp, then will the code run into an infininte loop? so that multiple messages could be sent and recieved without compiling?

[videoman]

Hello, I have made my a program very similar to this. Just like yours, my programs client can send data and there server can receive it but I don't know how we can have the server not only receive from client but also send data back.

Take 15-20 minutes and type it in for yourself. Then you can leave comments on what each of the functions is doing, so you'll remember when you look back a few months down the road.
