Hi all,

I'm looking for a TCP server project that can handle many connections at once.
it is best if the project is implemented in C.

If someone know of such a project please let me know.

Thanks for the help,

It would help to know exactly what you mean by "TCP server". You mean an HTTP server? an FTP server? A simple program that accepts connections and closes them, doing nothing in between?
What exactly are you attempting to do?

Hi goncalopp,
as you said, "A simple program that accepts connections and closes them, doing nothing in between" just handling a lot of connections, maybe the only thing I need is to see the incomming data, and at the other side I will add the option to send replies using scripts.
Thanks,

Your description sounds like netcat. But you probably know that. Also, netcat is not multithreaded, so it won't accept concurrent connections.

While I don't know such a tool myself, I found a thread discussing a similar problem. The response about ucspi-tcp / tcpserver might be what you're looking for.

Yes, I know netcat, it is a nice tool, but not what I'm looking for, I'm looking for something more like GNU MyServer but just for TCP, I want to build the protocol stuck myself (on top of TCP protocol).

Did you try ucspi-tcp / tcpserver?
If you just want to have some scripts reply to predefined responses, I think it will suffice.

If, however, you want to do more than a stateless protocol, you're going to need a programming language that supports sockets (like C, C++, Java, Python, Ruby, etcetera) and you might as well do the sending/receiving/threading: it's such a small portion of the overall code that I doubt there will be frameworks for that - unless you're looking into a well defined protocol like HTTP, in which case there are thousands of them.
