Instead of just a big string of output, Get-NetTcpConnection returns a list of PowerShell objects. You’ll see output similar to what netstat provided. The only reason you need to elevate a PowerShell console is to see the program that owns the connection (like the netstat -b parameter).Ģ. Open up a PowerShell console as administrator. If you’re curious, run Get-Help Get-NetTCPConnection -Detailed to discover more examples.ġ. This tutorial isn’t going to cover all of the parameters that come with the Get-NetTCPConnection cmdlet. The Get-NetTCPConnection cmdlet is much more specific than netstat about what you want to see. Using PowerShell gives you a lot more control to see just what you want, rather than having to scroll through long lists of output. Now that you’ve got a chance to see how the old-school netstat utility shows active and listening ports, let’s see how to do it in PowerShell. Netstat -anb Using PowerShell to Find Active and Listening Ports By default, netstat attempts to resolve many IP addresses to names. You should now see that any names in the output have been turned into IP addresses. State – shows the state the port is in, usually this will be LISTENING or ESTABLISHED.ģ.For established connections, the IP of the client machine will be shown. If the Foreign Address is 0.0.0.0:0, the connection is listening for all IPs and all ports.
Foreign Address – shows the remote IP address the local connection is communicating with.A colon separates the IP address from the port that it is listening on. In that case, netstat will show the IP address of the NIC. In some cases, a service will only listen on a single Network Interface (NIC). For many services, this will be 0.0.0.0 for the IP part, meaning it is listening on all network interfaces. Local Address – shows the local IP address and port that is listening.Proto – shows either UDP or TCP to indicate the type of protocol used.
The output above is broken out into four columns: Using the -a parameter tells netstat to return listening and established connections. By default, netstat only returns listening ports. Run netstat -a to find all of the listening and established connections on the PC. Open up an elevated command prompt (cmd.exe).Ģ. To learn more about what netstat can do, run netstat /?.ġ. This tutorial will only use three of them. Let’s check out how to use it to find listening and established network connections. It’s been a reliable command-line utility to inspect local network connections for a long time. Netstat is one of those command-line utilities that seems like it’s been around forever. Using Netstat to Find Active and Listening Ports This tutorial us using PowerShell v7.2.0-preview.2 Both Windows PowerShell and PowerShell 6+ should work. This tutorial is using Windows 10 Build 21343.1 If you’d like to follow along with examples in this tutorial, be sure you have:

Auditing servers enables you to track object access and configuration changes, from modifications to security settings, to users who are accessing a particularly sensitive spreadsheet. Find out which process/application is using which TCP/UDP port on Windows Wednesday, 26 January 2011 03:29 Colasoft During the process of analyzing a network problem with a network analyzer tool or a protocol sniffer, especially when we find a suspicious worm or backdoor activity, we get only useful information like MAC addresses, IP addresses. You’ll be able to deal with those issues before they start to affect the people that use the servers on a day-to-day basis. If you monitor servers correctly, you’ll know well in advance if the server is under resource pressure from lack of disk space, RAM, or processor resources. Properly monitoring servers is a critical component in administering them.
