Socket To IP and port

Recommended Posts

acmecd

There is very nice well know script to get Socket To IP, that’s work good.

But, I need get with connected IP also remote port, (IP:Port) there are any ideas how to upgrade script.

; Function to return IP Address from a connected socket.
;----------------------------------------------------------------------
Func SocketToIP($SHOCKET)
    Local $sockaddr, $aRet

    $sockaddr = DllStructCreate("short;ushort;uint;char[8]")

    $aRet = DllCall("Ws2_32.dll", "int", "getpeername", "int", $SHOCKET, _
            "ptr", DllStructGetPtr($sockaddr), "int*", 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   ;==>SocketToIP

I'm going to go ahead and bump this, as it is exactly the same question I was going to ask.  I'd like to know how I can retrieve the client's port.

Give me just a bit more information what exactly you have and what exactly you want to achieve.

For example you have opened a connection to a server and want to know what local port is opened or what?

With a little bit more details I'm sure I can help you (if I have time ;)).

Yes, that is correct.  I would like to know which local port is in use by the connected socket.

I wrote this function a few years ago:

Func _Ws2_GetLocalPort($iSocket)
    ;funkey
    Local $hDLL = DllOpen("Ws2_32.dll")
    Local $tagIN_ADDR = "ulong S_addr;"
    Local $tagSOCKADDR_IN = "short sin_family;ushort sin_port;ptr sin_addr;char sin_zero[8];"
    Local $tIn_Addr = DllStructCreate($tagIN_ADDR)
    Local $tName = DllStructCreate($tagSOCKADDR_IN)
    DllStructSetData($tName, "sin_addr", DllStructGetPtr($tIn_Addr))

    Local $aRes = DllCall($hDLL, "int", "getsockname", "uint", $iSocket, "struct*", $tName, "int*", 512)
    Local $aRes2 = DllCall($hDLL, "ushort", "ntohs", "ushort", DllStructGetData($tName, 2))

    DllClose($hDLL)
    Return $aRes2[0]
EndFunc

Hope this is what you want.
