packeting

[d0n]

So i am new to this packet stuff and wanted to see what happens with the autoit help example

expandcollapse popup

#include <GUIConstants.au3>
; Set Some reusable info
; Set your Public IP address (@IPAddress1) here.
;==============================================
$IP=@IPAddress1
$port=4099

; Create a GUI for messages
;==============================================
Dim $GOOEY = GUICreate("My Server (IP: " & $IP & ")",300,200)
Dim $edit = GUICtrlCreateEdit("",10,10,280,180)
GUISetState()

; Start The TCP Services
;==============================================
TCPStartup ( )

; Create a Listening "SOCKET".
;   Using your IP Address and Port 33891.
;==============================================
$MainSocket=TCPListen($IP, $port)
; If the Socket creation fails, exit.
If $MainSocket = -1 Then Exit

; Initialize a variable to represent a connection
;==============================================
Dim $ConnectedSocket = -1

;Wait for and Accept a connection
;==============================================
Do
    $ConnectedSocket = TCPAccept($MainSocket)
Until $ConnectedSocket <> -1


; Get IP of client connecting
Dim $szIP_Accepted = SocketToIP($ConnectedSocket)

Dim $msg, $recv

; GUI Message Loop
;==============================================
While 1
   $msg = GUIGetMsg()

; GUI Closed
;--------------------
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop

; Try to receive (up to) 2048 bytes
;----------------------------------------------------------------
    $recv = TCPRecv( $ConnectedSocket, 2048 )
    
; If the receive failed with @error then the socket has disconnected
;----------------------------------------------------------------
    If @error Then ExitLoop

; Update the edit control with what we have received
;----------------------------------------------------------------
    If $recv <> "" Then GUICtrlSetData($edit, _
            $szIP_Accepted & " > " & $recv & @CRLF & GUICtrlRead($edit))
WEnd


If $ConnectedSocket <> -1 Then TCPCloseSocket( $ConnectedSocket )

TCPShutDown()


; Function to return IP Address from a connected socket.
;----------------------------------------------------------------------
Func SocketToIP($SHOCKET)
    Local $sockaddr = DLLStructCreate("short;ushort;uint;char[8]")

    Local $aRet = DLLCall("Ws2_32.dll","int","getpeername","int",$SHOCKET, _
            "ptr",DLLStructGetPtr($sockaddr),"int_ptr",DLLStructGetSize($sockaddr))
    If Not @error And $aRet[0] = 0 Then
        $aRet = DLLCall("Ws2_32.dll","str","inet_ntoa","int",DLLStructGetData($sockaddr,3))
        If Not @error Then $aRet = $aRet[0]
    Else
        $aRet = 0
    EndIf

    $sockaddr = 0

    Return $aRet
EndFunc

so this is pretty much what is there on the example i just changed the port

but nothing really happens when i do stuff :S

whats am i doing wrong here, sorry this is only my 1st time trying out packet with autoit :S

Do you have a client to connect to it? Try this. Run the server then run this.

If I send 'aaa' through the client, my result is '192.168.1.101 > aaa'.
