Daemon Port Listener (Denial of Service Attack)

진행중 등록 시간: 5년 전 착불
진행중 착불

I have a daemon that is a port listener. It listens for incoming connections and routs them through a specific port. The connection thought winsock then passes onto and external application DLL. The issue is that this website has heavy usage. We have about 10 to 30 denial of service attacks on the website. This causes the daemon to stop running and opening the external program.

I need someone that is an expert in WinSock, C, C++,C#. I need help figuring out a solution to this problem. The original developers of this code are no longer available to help. This needs to be fixed and the code is very hard to follow. Again exceptional experience in WinSock, C, C++, C#. If your skills are fair in any of these languages please do not make an offer. Thanks and good luck bidding.
