PBQ 4: Python Port Scanner Script

Python Port Scanning Script Development

Szenario

During a penetration test, you gain access to a system with a limited user interface. This machine appears to have access to an isolated network that you would like to port scan. You need to complete a Python port scanning script to identify open ports on target systems in the isolated network. Target: The script should scan ports 21 (FTP) and 22 (SSH) on a host provided as a command-line argument.

Drag the appropriate code segments into the correct positions to complete the functional port scanning script. The script must: 1) Use Python, 2) Define ports to scan, 3) Iterate through ports properly, 4) Call the scan function with command-line argument.
