- Type tasklist | findstr ‘[PID]’.
How do I find out what application is using a TCP port?
1) Open the command prompt. 2) Type “netstat -ano” without the quotes. -a:Displays all active TCP connections and the TCP and UDP ports on which the computer is listening. -n: Displays active TCP connections, however, addresses and port numbers are expressed numerically and no attempt is made to determine names.
Which process ID is running on specific port?
We can simply pipe the netstat output to the grep command to get the process information on an individual port. 3. Using netstat
- l – show only listening sockets.
- t – show TCP connections.
- n – show addresses in a numerical form.
- u – show UDP connections.
- p – show process id/program name.
How do I kill a port process?

What is the use of port 135?
Port 135 exposes where DCOM services can be found on a machine. Hacker tools such as “epdump” (Endpoint Dump) can immediately identify every DCOM-related server/service running on the user”s hosting computer and match them up with known exploits against those services.
Does port 445 need to be open?
Note that blocking TCP 445 will prevent file and printer sharing – if this is required for business, you may need to leave the port open on some internal firewalls. If file sharing is needed externally (for example, for home users), use a VPN to provide access to it.

What does netstat do in Linux?
Netstat is a command line utility for Linux that prints network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. Netstat can be used to diagnose network issues and service problems.
What is the port 443?
Port 443 is a virtual port that computers use to divert network traffic. Billions of people across the globe use it every single day. Any web search you make, your computer connects with a server that hosts that information and fetches it for you. This connection is made via a port – either HTTPS or HTTP port.
How do you check what is running on port 8080?

- Hold down the Windows key and press the R key to open the Run dialog.
- Type “cmd” and click OK in the Run dialog.
- Verify the Command Prompt opens.
- Type “netstat -a -n -o | find “8080””. A list of processes using port 8080 are displayed.
