How to develop a network idle port scanning tool through Python
Overview:
A network port is an interface in a computer system used to communicate with external devices or applications. Port scanning can help us determine which ports are open in the system and find network vulnerabilities in the system. Python is a simple and powerful programming language that we can use to develop our own network idle port scanning tool. This article will introduce how to use Python to develop a network idle port scanning tool.
Steps:
socket
module to communicate with the target host and the argparse
module to parse command line arguments. argparse
module to create a parser to receive specified arguments from the command line. We can use the argparse
module to easily parse command line input. socket
module, we can connect to the target host by creating a socket object and try to connect to the specific port of that host . We can use a for
loop to iterate through all ports to be scanned. socket
module's connect_ex()
method to establish a connection with the target host. If the return value is 0, it means that the connection is successfully established and the port is open. If the return value is not 0, the connection failed and the port may be closed. Summary:
Developing a network idle port scanning tool through Python is a very useful skill. It helps us find vulnerabilities in our network and take appropriate security measures. This article provides some simple steps to help beginners understand how to use Python to develop their own network idle port scanning tool. Through continuous learning and practice, we can improve our programming skills and create more powerful and flexible tools to meet our needs. I wish you all success in developing a network idle port scanning tool using Python!
