What this article shares with you is about a quick way to check all the open ports of a windows computer with one click. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1, let's first popularize the basics (don't be too wordy about Xiaobian, take care of new friends). The command used to view all current network connections under the DOS command is netstat-an (- an is the parameter of the command, meaning to show the current IP address and listening port of all local-remote connections in digital form. ), we can see the result after entering enter directly in the command prompt window.

2. If there are too many programs connecting to the network, you will be so dazzled that you can't easily see which ports are open (in listening state). Then how to solve it? Fortunately, the editor also has the powerful string search command find / I (/ I is also a parameter, indicating that the search is case-insensitive). So we can easily display all our open port numbers by using the find / I "LISTENING" command later.

Finally, the combination of the above two small commands is our finished product batch processing today! I wonder if you can write it yourself. Not yet, let's take a look below.

@ echo offecho.netstat-an | find / I "LISTENING" echo.&echo Please press any key to exit. Pause > nul

4, you need to create a new notepad text document, and then copy the above code into it, select the file → in the menu bar and save it as an one-click check port. Bat. Then double-click to open the batch file and you can see all the open ports on your computer.

The above is a quick way to check all the open ports of windows computers with one click. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
