[TUT] How To: Close Ports

[JpK]

So, I've been looking for a while on just how to close a port on a computer. I simply couldn't find a way. Well, i finally found it. This'll only work for windows users (unless your unix version OS has netsh).

It's actually quite simple. here's the command for it:

netsh firewall delete portopening TCP portnumber

It's that simple. Simply go to START -> RUN -> and type in that command up there, and it'll close it for you.

or, you can also open up command prompt (START -> RUN -> CMD) and type in "netsh" without the quotes to get to your windows firewall settings.

However, since i'm such a nice guy, I wrote it all out in a vbs script for you so that it's automatically runable. as well as a batch script. so here you are fellas:

.VBS Script

set ss = createobject("wscript.shell")
set ws = wscript
dim PORT
PORT = InputBox("Enter the port you wish to close:")
ss.run "netsh.exe"
ws.sleep 1000
ss.sendkeys "firewall delete portopening TCP " & PORT
ss.sendkeys "{enter}"
ws.sleep 500
'ss.sendkeys "exit"
'ss.sendkeys "{enter}"

.BAT Script

@echo off
title Port Closer
echo Port Closer
echo.
set /p port=Type the port number you wish to close here:
netsh firewall delete portopening TCP %port%
msg /w * Port %port% has been closed.
exit
