How does Windows view port occupancy?

Start--run--cmd Enter the command prompt input Netstat-ano to see all the connected PID in Task Manager to find this PID program if the task manager does not have the PID, you can select "View" in Task Manager-"Choose columns" often, We started the application when we found that the system needs a port to be occupied by another program, how to know who owns the port we need, many people have a headache, the following is a very simple method, I hope to be useful

If we need to determine who's taking up our 9050 ports,

1. Windows platform executes under Windows command Line window:

1. View all port occupancy C:/>netstat-ano

Protocol local address external address state PID

TCP 127.0.0.1:14340.0.0.0:0 Listening 3236

TCP 127.0.0.1:56790.0.0.0:0 Listening 4168

TCP 127.0.0.1:74380.0.0.0:0 Listening 4168

TCP 127.0.0.1:80150.0.0.0:0 Listening 1456

TCP 192.168.3.230:1390.0.0.0:0 Listening 4

TCP 192.168.3.230:1957 220.181.31.225:443 established 3068

TCP 192.168.3.230:2020 183.62.96.189:1522 established 1456

TCP 192.168.3.230:2927 117.79.91.18:80 established 4732

TCP 192.168.3.230:2929 117.79.91.18:80 established 4732

TCP 192.168.3.230:2930 117.79.91.18:80 established 4732

TCP 192.168.3.230:2931 117.79.91.18:80 established 4732

2. View the occupancy of the specified port C:/>netstat-aon|findstr "9050"

Protocol local address external address state PID

TCP 127.0.0.1:9050 0.0.0.0:0 Listening 2016

See, the port is occupied by process number 2016, and continue with the following command: (You can also see the PID corresponding process in Task Manager)

3. View PID corresponding process C:/>TASKLIST|FINDSTR "2016"

Image name PID session name Session # Memory usage ========================= ======== ================

Tor.exe 2016 Console 0 16,064 K

It's clear that Tor is taking up your port.

4. End the process c:/>taskkill/f/t/im Tor.exe
