The Port Scanner tool will then display the status of each port between and including the starting and ending ports below the scan button. For example, to scan by custom package, select 'custom', enter each desired port to scan on its own line in the text box shown, and select 'Scan'. A basic breakdown of what is in the free scan: Port 21 - FTP - This is the classic file transfer protocol. Port 23 - Telnet - This is a very old and simple terminal server. It is insecure and in modern times used to configure routers or other devices via command line interface. Port 25 - SMTP - This one is the Simple Mail Transfer Protocol.

Port Scan The last tab on the Network Utility window is Port Scan, useful for determining the status of various internet protocol ports on a particular machine. While your Mac is assigned a specific IP address, the various services that it uses — email, web browsing, and so on — are each assigned a TCP or UDP port number.
It’s not nmap, but then it’s not meant to be. Network Utility has a port scanner – it’s built in and really easy to use. Since Network Utility is distributed with every copy of Mac OS X it stands to reason that every copy of Mac OS X has the ability to scan a port without using a GUI tool. Enter one of the best named tools in Mac OS X, stroke. Stroke is the command line back-end to the Port Scan tab of Network Utility. To use stroke, you will need to cd into the Network Utility application bundle and then cd into Contents and then Resources.Once you are in the /Applications/Utilities/Network Utility.app/Contents/Resources, you will need to provide stroke with an IP address (or name), followed by the first port to scan and then the last (or the same number twice if your range is only one IP address. For example, if you want to port scan port 80 on your own system you could use the following:./stroke 127.0.0.1 80 80But you shouldn’t just stroke yourself (sorry, couldn’t help it). You should also stroke others (Clarence Carter be damned!). So if you want to port scan www.google.com for port 80 the following would achieve such a lofty goal:
./stroke www.google.com 80 80Because the name www.google.com has to resolve, you’re actually able to check whether a DNS error occurs and whether you can communicate over port 80 to the host in one command. If you want to make a copy of stroke into a directory and then add it to your environment variable’s PATH you can then use it without needing to change your working directory.
Much malicious software such as Trojan, Virus, Backdoor, Malware, etc are hidden in your computer, and they are using open ports for sending information and connection over TCP/IP to its owner (Hacker).
Hackers gains access to your computer by using these ports. So you must know what are the open ports in your computer system.
The Port is working in your system as a gate in your house. If you have an open gate in your house then the thief and another bad intention guy can easily get into your house.
Same if you have open ports on your computer then the hacker can easily get into your system and steal the important and useful information from your computer.
You can check your system for open ports by using Port checker or scanner.
Port scanner or Port checker are the tools used for checking open ports of computer system in network.
These tools scan your whole system TCP /UDP connection and check for open ports. Such type of Tools is also looking for running services and associated ports.
So after completing port scanning of your system, you will be able to find out the open ports and running services as well.
In this article I am going to describe all about the open port checker or scanner By using these tools you can check open port and running services.
Nmap (Network mapper) is a free and open source tool for the network Discovery and security auditing.
It is available for the windows, LINUX, MAC, and other operating systems as well. This tool can determine the live host, close and open ports, and running services.
They still have the capacity to scan the system and finding vulnerabilities. This tool has an inbuilt GUI interface called ZenMAP.
Nmap is the best port checker right now on the web. For the tutorial, you can read my nmap network scanning series.
Nmap is Flexible, Powerful, Portable, Easy, Free, Well Documented, Supported, Acclaimed, Popular etc.

It is provide the free demo version for user so you can explore this tool for 30 days after that it is cost start from $249.
Unicornscan is a good port checker that utilizes it’s own userland TCP/IP stack, which allows it to run a asynchronous scans. This feature makes it faster than nmap and it can scan 65,535 ports in a relatively shorter time frame. it makes sense to use it for scanning large networks or a large number of ports due to its fast feature.
We will use unicornscan to scan all ports 65535, and make a list of those ports that are open. But its not able to detect running services on particular open ports. It identify open port only.
