发布时间: 2022-11-24 21:03:01    浏览次数:32 次

1.查找本机上的端口使用情况

netstat -an

 

 

2.查找指定端口的使用情况

C:\Windows\System32>netstat -ano | find "8002"
TCP 0.0.0.0:8002 0.0.0.0:0 LISTENING 2884
TCP [::]:8002 [::]:0 LISTENING 2884

参数说明:

-a 列出所有的

-n 数字的形式列出

-o 显示进程编号

输出结果:

第一列是协议类型,第二列是local address,第三列是remote address,第四列是状态,最后一列是进程编号

 

2.1找到占用端口的应用程序

查找结果的最后一列是进程编号,可以在任务管理器里找到对应的进程

C:\Windows\System32\inetsrv>netstat -ano | find "8080"

from netstat -h:

-a            Displays all connections and listening ports.

As in both current connections and listening ports (half open).

-n            Displays addresses and port numbers in numerical form.

As in, do not resolve addresses to host names.

Your computer can and regularly does connect to itself, usually for IPC or administrative tasks.

*.* = All IPv4 addresses (it's listening, so accept connections from any IPv4)
[::] = All IPv6 addresses (same reason as the last).
