How can you find out which process is listening on

Question

How can you find out which process is listening on a port on Windows?

Answer 1

Just open a command shell and type : (saying your port is 123456)

netstat -a -n -o | find "123456"

You will see everything you need

The headers are :

 Proto  Local Address          Foreign Address        State           PID
 TCP    0.0.0.0:37             0.0.0.0:0              LISTENING       1111

this is as mentioned here

Answer 2

Use below batch script which takes a process name as argument and gives netstat output for the process.

@echo off
set procName=%1
for /f "tokens=2 delims=," %%F in ('tasklist /nh /fi "imagename eq %1" /fo csv') do call :Foo %%~F
goto End

:Foo
set z=%1
echo netstat for : "%procName%" which had pid "%1"
echo ----------------------------------------------------------------------

netstat -ano |findstr %z%
goto :eof

:End

Answer 3

netstat -aon | find /i "listening"

Answer 4

There's a native GUI for Windows:

• Start>>All Programs>>Accessories>>System Tools>>Resource Monitor

or Run resmon.exe, or from TaskManager performance tab

Answer 5

netstat -a -o This shows the PID of the process running on a particular port.

Keep in mind the process id and go to Task manager and services or details tab and end the process which has the same PID.

Thus you can kill a process running on a particular port in windows.

Answer 6

Netstat -a displays all connection and listening ports -b displays executables -n stop resolve hostnames (numerical form) -o owning process

netstat -bano | findstr "7002"

netstat -ano > ano.txt 

Currports helps to search and filter
