哪位高手占用了小弟我的端口(如果:80)请现出原型

谁占用了我的端口(如果:80)请现出原型.

几个非常强大的命令,我认为作为一名程序员一定要懂这几个命令:
1.netstat -a 列出所有正在运行程序的端口 如下:
Active Connections

? Proto? Local Address??????Foreign Address????State
? TCP??? 0.0.0.0:90???????????? 0.0.0.0:0????????????? LISTENING
? TCP??? 0.0.0.0:135???????????0.0.0.0:0??????????????LISTENING
? TCP??? 0.0.0.0:445???????????0.0.0.0:0????????????? LISTENING
? TCP??? 0.0.0.0:1110?????????0.0.0.0:0????????????? LISTENING
? TCP??? 0.0.0.0:1433?????????0.0.0.0:0??????????????LISTENING
? TCP??? 0.0.0.0:8009?????????0.0.0.0:0????????????? LISTENING
? TCP??? 0.0.0.0:19780???????0.0.0.0:0????????????? LISTENING
? TCP??? 127.0.0.1:1052?????127.0.0.1:1110????ESTABLISHED
? TCP??? 127.0.0.1:1110?????127.0.0.1:1052????ESTABLISHED
? TCP??? 127.0.0.1:1141?????127.0.0.1:1433????ESTABLISHED
? TCP??? 127.0.0.1:1143?????127.0.0.1:1433????ESTABLISHED

2.netstat -ano 列出所有正在运行程序的端口及PID 如下:
Active Connections

? Proto? Local Address??Foreign Address???? State?????????? PID
? TCP??? 0.0.0.0:90???????? 0.0.0.0:0?????????? LISTENING?????? 3468
? TCP??? 0.0.0.0:135???????0.0.0.0:0?????????? LISTENING?????? 1120
? TCP??? 0.0.0.0:445???????0.0.0.0:0?????????? LISTENING?????? 4
? TCP??? 0.0.0.0:1110?????0.0.0.0:0?????????? LISTENING?????? 1680
? TCP??? 0.0.0.0:1433?????0.0.0.0:0?????????? LISTENING?????? 2880
? TCP??? 0.0.0.0:8009?????0.0.0.0:0?????????? LISTENING?????? 3468
? TCP??? 0.0.0.0:19780????0.0.0.0:0?????????? LISTENING?????? 1680
? TCP??? 127.0.0.1:1052??127.0.0.1:1110???ESTABLISHED???? 3368
? TCP??? 127.0.0.1:1110??127.0.0.1:1052???ESTABLISHED???? 1680

? TCP??? 127.0.0.1:1143??127.0.0.1:1433???ESTABLISHED???? 3468
? TCP??? 127.0.0.1:1433??127.0.0.1:1141???ESTABLISHED???? 2880
? TCP??? 127.0.0.1:1433??127.0.0.1:1143???ESTABLISHED???? 2880
? TCP??? 127.0.0.1:8005???0.0.0.0:0?????????? LISTENING?????? 3468
? UDP??? 0.0.0.0:445????????? *:*??????????????????????????????? 4

3.netstat -anb 列出所有正在运行程序的端口,PID及使用这个端口的进程( ):

注:也可直接开始运行 cmd /c netstat -anb
?? 如果你的系统没有netstat 这个命令那可能是你的系统PATH配置有误:
PATH = %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;
