TCP question

[MirnesC2]

Client

TCPStartup()

$TCPConnect = TCPConnect(@IPAddress1, 403)

If $TCPConnect = -1 Then Exit

TCPSend($TCPConnect, "Hello")

Server

TCPStartup()

$TCPListen = TCPListen(@IPAddress1, 403)

Do
    $TCPAccept = TCPAccept($TCPListen)
Until $TCPAccept <> -1

Do
    $TCPRecive = TCPRecv($TCPAccept, 1000000)
Until $TCPRecive <> ""

MsgBox(0, "Data recived", $TCPRecive)

Ok so I watched a tutorial online and was able to string this together. What it does is send "hello" into a message box. This only sends data from my pc to my pc. How can I make it so that I can send "Hello" from my pc to someone elses pc? Whos IP addresses do I use in each field? What port?

You need to change the ip in TCPConnect. The ports doesn't really matter much, take one that you don't use in normal case. Or let the users change themselves.

On the server-side, @IPAddress1 is the address that the server is listening for connections on, so that can remain unchanged.

On the client-side, you want the address of the server to connect to, so change that to the address of the one running the server-side.

So...

PersonB is running server.

PersonA is running client.

PersonA needs to change the IP to PersonB 's IP in the client.au3?

PersonB leaves @IPAddress1 as it is under server.au3?

and this will allow PersonA to send a message to PersonB? Correct?

Also which IP is being used? Is there a macro? ( like @IP2)

um well you will have to know the server's ip(@ipadress1 on server computer) so that the client cud connect to it.. yo can check out the tic tac toe in my signature that uses tcp.. such that the client and server software is the same

I modified it a bit so I can learn more about it but it doesn't seem to work the way I want it to.

CLIENT

#include <GUIConstantsEx.au3>

GUICreate("TCPClient",180,40)
GUISetState(@SW_SHOW)

$packet = GUICtrlCreateInput("",10,10,90,20)
$send = GUICtrlCreateButton("Send",110,10,60,20)

TCPStartup()

$TCPConnect = TCPConnect(@IPAddress1, 403)

If $TCPConnect = -1 Then Exit



While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $send
            TCPSend($TCPConnect, GUICtrlRead($packet))
    EndSwitch
WEnd

SERVER

TCPStartup()

$TCPListen = TCPListen(@IPAddress1, 403)



While 1
    Do
    $TCPAccept = TCPAccept($TCPListen)
    Until $TCPAccept <> -1

    Do
        $TCPRecive = TCPRecv($TCPAccept, 1000000)
    Until $TCPRecive <> ""

    MsgBox(0, "Data recived", $TCPRecive)

    If $TCPRecive = "exit" Then
        ExitLoop
    EndIf

    $TCPAccept = -1
    $TCPRecive = ""
WEnd

I want to to be able to send message after message until TCPRecive(the message) = exit.
