Windows打开端口命令行

Question

Is there any way to see open ports of windows in a specific range using command line?

For example i want to see open ports in range 1-1024.

Answer 1

This will list all open (in use) ports.

netstat -na

Filtering is a bit harder. This script takes two ports as the (inclusive) range of local ports to filter for.

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION

SET STARTPORT=%1
SET ENDPORT=%2

FOR /F "delims=|" %%l IN ('netstat -na') DO (
    FOR /F "tokens=2" %%a IN ("%%l") DO (
        REM IPv6 uses colons, too.
    SET "LOCAL=%%~a"
    SET "LOCAL=!LOCAL:*]=0!"
        FOR /F "delims=: tokens=2" %%p IN ("!LOCAL!") DO (
            IF %%p LEQ %ENDPORT% ( IF %%p GEQ %STARTPORT% ( @ECHO %%l ) )
        )
    )
)
