Using a single command, you can get a list of all the ports that are in use by various programs. This method is quite useful if you want to take a quick glance at the ports in use.

This option lets you open the command prompt with admin rights. In the elevated command prompt window, execute the below command. You can copy the command and paste it in the command prompt window by right-clicking inside it.

In the resulting output, you will see the port number right next to the IP address ex: You can see the highlighted portion in the below image for better representation. Keep in mind that the list will not be refreshed automatically.

You have to execute the command again when you need an updated list. If you want the used port list to be updated automatically, use the below two methods. Nirsoft Utilities has a pretty neat and lightweight tool called CurrPorts which lists all the ports that are in use by Windows and other programs. First, download CurrPorts from the official website. On a FreeBSD Unix system, as with other BSD Unix systems, you have a number of utilities with a base system install that can be used for listing open files, running processes, and network connections.

The netstat utility is maintained as a part of the FreeBSD base system by the FreeBSD core developers, and offers exactly the sort of functionality you need to list open ports on your system. To list open network ports and the processes that own them on FreeBSD with netstat, you can use this command:. The localhost. You can add the -n option to netstat to get port numbers instead of having the utility try to provide names for services:. This information can be used to determine what services are running, in cases where services are using standard ports.

For instance, if you wanted to find out what was up with port , you might use this command:. In addition to netstat, the more limited command sockstat is effectively tailor-made for this kind of information gathering.

To get a listing of listening ports and their associated processes, you can use this command:. As with FreeBSD, the obvious choice of tool to use for listing open ports is netstat. Most Linux distributions use a different version of the utility, however maintained separately from the Linux distribution, as an independent software development project.

One consequence of that fact is that the command line options used to achieve the same results may be different with FreeBSD than with Debian, Ubuntu, or Fedora Core Linux systems.

On a typical Linux system, this command will list open network ports and the processes that own them:. Microsoft Windows also offers a netstat command that can be executed from the command line to get a list of open ports.

The standard MS Windows version of netstat is slightly more limited than its Unix-like system counterparts, but still suffices to get a listing of listening services:. For most commercial UNIX systems, even if there is not a version of netstat or sockstat available, you should be able to install lsof -- which is short for "list open files". Most Linux distributions and BSD unix systems will provide lsof with a default install or through their respective software management systems.

Some commercial UNIX systems do so as well, and for many others you can download it. The following command will limit the output of the utility to network ports:. He's covered a variety of topics for over twenty years and is an avid promoter of open source.
