portscanner

Brief introductionPython-nmap is a Python library that uses nmap for port scanning, which makes it easy to generate NMAP scan reports and can help system administrators automate scan tasks and generate reports. At the same time, it also supports Nmap script output.You can see that Python-nmap has only four py files (__init__.py, nmap.py, test.py, test_nmap.py), Here's a read.__init__.pyExcept for dozens of lines of comments, the real code is only four lines, the basic content is to import some b

RST package, the port is closed, and if you receive a syn/ack packet, the corresponding port is open. TCP FIN Scan: This way sends a FIN packet that represents the removal of an active TCP connection and lets the other person close the connection. If an RST package is received, the corresponding port is closed. TCP Xmas Scan: This method is set to 1 packets by sending the PSH, FIN, URG, and TCP flag bits. If an RST package is received, the corresponding port is closed. Below we will use Python3

TCP Xmas Scan: This method is set to 1 packets by sending the PSH, FIN, URG, and TCP flag bits. If an RST package is received, the corresponding port is closed. Below we will use Python3 to implement the TCP full-port scanner, the following into the programming link.Coding combat全连接扫描The core of the approach is to make a TCP connection for different por

IntroducedPython-nmap is a port scanning tool based on the system Nmap command, which is simple and convenient to use.Recently, in order to enhance server security and supervision, it is necessary to keep the company server open port scan records every day, once there is an increase in the decrease can be found.Previously wrote a https://github.com/bashhu/monitor-shell/blob/master/python-script/scan_port.sh with the shell.Recently, we are going to improve our operation and maintenance platform,
