When non-administrators wished to run their own web servers, they often chose port 8080 to host a secondary or alternate web server. Historically, only authorized system administrators were able to establish and operate a web server on port 80, since this was within the first 1023-port privileged region. It can also be used as an alternative port for any protocol like ssh, FTP, NTP, BOOTP, etc. Port 8443 is a default alternative port for HTTPS servers.

Port 8080 is a non-standard, high number port that is popular as an alternative port for HTTP servers, most often application servers. Activate the PID column to see the name of the process listening on port 80. This tool will list the PID (Process Identifier) that is listening to port 80. How do I find out what application is using port 8080? Timeout implies a firewall is blocking access. A refused connection means nothing is running, whereas an accepted connection means something is running. From outside the server, telnet host port can be used to check connections. On the server itself, use Netstat -an to check to see which ports are listening. How can I tell if a server is listening on a port? To end that process, simply enter taskkill /PID xxxx. The -o shows the process id, which you can look up in your task manager or processes tab. This tool provides a list of all open ports and their associated processes. How do I find out what application is using a TCP port? In Netstat, stat stands for state or statistics, which tells you the current network status of every TCP connection. Netstat is a diagnostic tool that creates a list of open ports that the machine is listening to, as well as the ports it is currently connected to on other machines. What application is listening on a TCP IP port in Windows? To stop anything running in port 80 the following command can be used from command prompt. There would be situations were some other process is running at port 80. This will bring up the resource monitor window. To open resource monitor type resmon.exe in run. Once you’re there, you can use the End Process, Open File Location, or Go to Service(s) options to control the process or stop it.Īlternatively you can even use resource monitor to stop any process that is running. Now you can simply open up Task Manager-you might have to use the option to Show Processes for All Users, and then you’ll be able to find the PID in the list. Find the one that’s bound to the port that you’re trying to troubleshoot-for this example, you’ll see that 0.0.0.0:80, or port 80, is in use by PID 1184. If you look on the right-hand side, you’ll see where I’ve highlighted the list of PIDs, or Process Identifiers. You can also use this other method, which takes an extra step, but makes it easier to locate the actual process: You’ll see the process name in the list, and you can search for it. This will immediately show you a list, although it’s maybe a little complicated. Open up a command prompt and type in the following-you may have to open in Administrator mode to see all processes: Then we can use that number to look up exactly which process it is.

The first step is to use a command-line tool to see what ports are in use, and use a special flag that tells us which port is assigned to each Windows process identifier number. Using Built-In Tools to See What is Listening on a Port There’s a number of ways to tell which application has the port locked, here we will use a windows built-in way using the command line and Task Manager.

So if you need to use an in-use port, how do you tell what application is holding it? Whenever an application wants to make itself accessible over the network, it claims a TCP/IP port, which means that port can’t be used by anything else.
