Option One,
Start--run--cmd Enter the command prompt and enter netstat -ano to see the PID of all connections. After that, find the program corresponding to this PID in the task manager. If there is no PID in the task manager, you can find it in the task manager Select "View" - "Select Column" in the manager.
Often, when we start the application, we find that the port required by the system is occupied by other programs. How to know who occupies the port we need is a headache for many people. This is a very simple method, I hope it will be useful to everyone.
If we need to determine who occupies our 9050 port
1. The Windows platform
is executed under the Windows command line window:
1. View all port occupancy
C:\>netstat -ano
Protocol Local Address External Address Status PID
TCP 127.0.0.1:1434 0.0.0.0:0 LISTENING 3236
TCP 127.0.0.1:5679 0.0.0.0:0 LISTENING 4168
TCP 127.0.0.1:7438 0.0.0.0:0 LISTENING 4168
TCP 127.0.0.1:8015 0.0.0.0:0 LISTENING 1456
TCP 192.168.3.230:139 0.0.0.0:0 LISTENING 4

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. Check the occupancy of the specified port
C:\> netstat -aon|findstr "9050"
Protocol Local Address External Address Status PID
TCP 127.0.0.1:9050 0.0.0.0:0 LISTENING 2016
P: Did you see that the port is occupied by the process with the process ID of 2016, continue to execute the following command: (You can also go to the task manager to view the process corresponding to the pid)
3. View the process corresponding to the PID
C:\> tasklist|findstr "2016"
Image Name PID Session Name Session# Memory Usage
========================================= ========
tor.exe 2016 Console 0 16,064 K
P: Clearly, tor is taking your port.
4. End the process
C:\>taskkill /f /t /im tor.exe
其他不懂的用 help吧~
方案二、
用TCP View吧 看到很清楚，软件见附件
