Modify an existing simple TCP server (C program) to connect to a CCTV NVR/DVR to allow data/test strings to be sent and displayed. The NVR/DVR has a built in TCP client.

I need you to develop some software for me. I would like this software to be developed using [url removed, login to view] project is to modify an existing ubuntu based TCP server to send data to a Windows based CCTV NVR/DVR.

The existing server has been programmed in C on linux ubuntu. The existing server will connect to the NVR/DVR client on the windows machine but it does not operate correctly and allow data to be displayed on the NVR/DVR. The server creates a tcp socket,listens,accepts and commences sending data but it then abruptly disconnects.

I need someone who has an in depth knowledge of TCP connection protocols and that can troubleshoot problems. I suspect it is a very simple fix but I cannot be sure. I am able to successfully send data to the NVR/DVR using other free TCP server programs so I know that there is a solution.

I can provide pcap files and remote access for testing purposes.

Thank you for taking the time to read this project summary.
