A simple batch program for Port Scanning

Hi friends in this post we are going to see how to create Batch programming for port scanning.

    * Open Notepad
    * Paste this code:




@ECHO off

color 0a
cd\
C:
cls
for /L %%v in (1,1,11) do telnet %1 %%v
GOTO scan2
:scan2
for /L %%w in (12,1,20) do telnet %1 %%w

    * Save it with .bat extension(for eg: portscanner.bat)
    * Goto command prompt and, goto the exact location of where this port.bat is located.
    * now type the following command on the command prompt.   port 127.0.0.1
    * This will port scan upto 20 continuous ports starting from 1 to 20 on your localhost.
    * This is not much efficient and not much reliable, but this is just to show, that there is a possibility for
port scanning automation using Batch file programming
