Block A Port

[Erik.]

Hello,

1)How can i make a program that can see what program what port use.

so i can see for example:

msn: port 5000

firefox:8080

How can i see what program uses what port

2) how to block a port so no data can be send?

and how to check if the ports realy blocked?

For #1, I'd use something like this

#include <Constants.au3>
    $netstat = Run(@ComSpec & " /c netstat -n -b", @SystemDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
    $line = StdoutRead($netstat)
$line = StringSplit($line, @LF)

Then do a bunch of String* Functions on it to retrieve the right values. To see the output just run cmd and type "netstat -n -b". I know this Isn't the best way, but it could work. Dont know about blocking a port... maybe just change firewall settings.

On the command line you should be able to block a port using

netsh firewall set portopening ALL 500 DISABLE

or something like that.

The program is for school so i do not have any acess:P

i hope you will still help me:P

i want when i open the program and then a port get blocked.

When i close it the port will be open.

Does no one has a simple script to do i?

[Don N]

why not jsut do this

http://support.microsoft.com/kb/813878#E0RB0ACAAA

one time and then write a script to start and stop the service? Thatd propbably be easiest.

[Erik.]

The only script example in this entire thread will help you to see what is being used, but you have to output the data. He said as far as closing ports he doesnt know.

He didnt write an entire script for you, just a snippet to give you something to build on.

CDkids script is cool, I added this if you don;t understand it:

#include <Constants.au3>
#include <array.au3>
$netstat = Run(@ComSpec & " /c netstat -n -b", @SystemDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
    $line = StdoutRead($netstat)
    ConsoleWrite($line)
$line = StringSplit($line, @LF)
_ArrayDisplay( $line, "Connections")

Hi,

Is it possible to look at a port?

Can i make something that look at a port and when some data is comming in my keybord and mouse will be disabled?

The program will run when you start the pc.

The can see what you are doing at your pc so i can not check my mail anymore:(

The problem is that there always data send at that port to your pc and to the server

Is there a way that when there is nore data send ore comming in that my keybord and mouse will be blocked??

EDIT:

What means Warnngs at my profil at the site??

i see something that i do not see at other poeple

i see warning 0% but after it i see some bleu lines.

What does that means?
