server port scanner

Implement Windows Forms) Implement console version) It's easy to use another port scanner, but if you can do one, it's of course a pleasant thing. In fact, it is not difficult to implement your own port scanner. The principle is also relatively simple, as long as we have basicNetworkKnowledge, understand the

connections. That is to say, I can connect to the FTP server target.com from evil.com, And I can ask this FTP server to send files anywhere on the Internet for myself! This feature worked well when rfc959 was completed in 1985. However, in today's Internet, we cannot allow people to hijack the FTP server and send data to any node on the Internet. As hobbit said

Idea: Use the socket for connection testing, where the client connects to the server.The core code is as follows:From socket import *def try_port (Ip,port,protocol = sock_stream): s = socket (Af_inet,protocol) Try:s.connect ((str (IP), int (port)) ) return Trueexcept:return falsefinally:s.close ()　　Call Method:1.

The instance is a C-implemented command-line-based port-scanning code and is a non-blocking way to test connectivity to the IP and port. For everyone to use and learning convenience, has been in the code as many places as possible to add a note, I believe that to help you understand the C-port scan has a great help. The specific function code is as follows:
