I need to implement something that could send data from a not-ROS-running System(A) to a ROS-running System(Z) and later sending data from Z back to A using a TCP connection (using socket). I was looking for something on that page http://wiki.ros.org/ROS/TCPROS but it is not clear for me. Are there any tutorials/codes to launch a server on a ROS-running System and listening for clients? Are there any packages that allow to implement TCP communication?

ROSTCP is an adapter that lets ROS send messages over TCP for topics; not for general use.

If you want a TCP socket, use the standard OS interface for creating a TCP socket.

There are many good tutorials about this online; here are a few:

Thank you for your answer, I'll on that. I found some helpful code. But client_node cannot connect to the server. https://github.com/abhinavjain241/com...

I'm not familiar with that project, and I can't help you with it. I'd recommend that you ask a new question or open an issue on that repository. For either, I recommend that you include the specifics of your issue such as the exact commands and exact output.
