Python scans server ports in batches, and python scans server ports in batches.

Python scans server ports in batches, and python scans server ports in batches.

I wrote a simple Port Scan script in Python. The simple logic is as follows:

1. python DetectHostPort. py iplist.txt (stores the text of the IP address list to be scanned, one address per line)

2. Enter the scan port, scan time, and scan interval.

3. Output scan information.

 

The source code is pasted below. You are welcome to make a brick.

This script has a disadvantage. Although servers can be scanned in batches, ports cannot be scanned in batches. Of course, it is also easy to add this function, or which of the gods has a better script can also be posted for learning.
