Example of Python3 Batch Scan Port

Usage

This script is used to scan ports in batches

1. Create an input file in the same directory, and the attribute inputFile is the input file name

2. The attribute th is the number of threads

3. Attribute port is the target port for probing

4. Property arg is the default command

It is not recommended to scan all ports, which is very slow. There are common ports in the script, which can be used directly

The port corresponding service under the default command may be inaccurate. You can add-sV to detect the version in detail, or use this script to detect the output of this script specially
