cmd-端口扫面及ip网段扫描

 

 

用于测试网段中的ip（仅限于未开启防火墙的）

for /l %i in (1,1,255) do @ping xxx.xxx.xxx.%i -w 1 -n 1 | find /i "ttl="

 

 

 

测试cmd扫描目标端口

在win10 1809版本中实验正常，在20H2中实验出问题

for /l %i in (75,1,85) do @start /min telnet 192.168.10.112 %i & ping -n 3 127.1 > nul & (tasklist /FI "windowtitle eq Telnet 192.168.10.112" | find "telnet.exe" >nul && (echo %i && taskkill /FI "windowtitle eq Telnet 192.168.10.112" >nul)) 

 

 

在1904版本中实验结果为：80

在20H4中则为以下结果

C:\Users\29240>for /l %i in (80,1,85) do @start /min telnet 192.168.10.112 %i & ping -n 3 127.1 > nul & (tasklist /FI "windowtitle eq Telnet 192.168.10.112" | find "telnet.exe" >nul && (echo %i && taskkill /FI "windowtitle eq Telnet 192.168.10.112" >nul))
