Good day!
A quick wiki for port scanner:
A port scanner is a software application designed to probe a server or host for open ports. This is often used by administrators to verify security policies of their networks and by attackers to identify running services on a host with the view to compromise it.
A port scan or portscan can be defined as an attack that sends client requests to a range of server port addresses on a host, with the goal of finding an active port and exploiting a known vulnerability of that service, although the majority of uses of a port scan are not attacks and are simple probes to determine services available on a remote machine.
Port Scanning is the name for the technique used to identify open ports and services available on a network host. It is sometimes utilized by security technicians to audit computers for vulnerabilities, however, it is also used by hackers to target victims. It can be used to send requests to connect to the targeted computers, and then keep track of the ports which appear to be opened, or those that respond to the request.
When a criminal targets a house for a burglary, typically the first thing he or she checks is if there is an open window or door through which access to the home can be gained. A Port scan is similar, only the windows and doors are the ports of the individual's personal computer. While a hacker may not decide to "break in" at that moment, he or she will have determined if easy access is available. Many people feel this activity should be illegal, which it is not, however, due to the fact that the potential attacker is merely checking to see if a possible connection could be made, in most areas, it is not considered a crime. However, if repetitive port scans are made, a denial of service can be created.
Hackers typically utilize port scanning because it is an easy way in which they can quickly discover services they can break into. In some cases, hackers can even open the ports themselves in order to access the targeted computer. Hackers also use port scanners to conduct tests for open ports on Personal Computers that are connected to the web.
pyportscan.py is a port scanner I created written in python. It uses a simple multi threaded technique and will try to connect to every port you define either range for `-r` option or specified ports using `-s` followed by port numbers separated by commas.
This program is intended for individuals or pentesters to test their network to automate the process of checking what ports are opened on a remote server.
Here is the screenshot on how to use this script.
