Can AutoIt send packets to Diablo2?

[saufriel]

i belive that i read something like this a few months ago...and i think it was a autoit script, so my question is, where can i get this?

i should be a func, where i can wirte in the packet which i wanted to send

i hope this is possible

greets

4 words you should use

[jvanegmond]

If you are looking for sending TCP packets, this 'hex-sender' could be of use...

$Hex = "AA 00 13 7E 1B 43 4F 4E 4E 45 43 54 45 44 20 53 45 52 56 45 52 0A "

$Str = StringSplit($Hex," ")

$Hex = ''
For $x = 1 to $Str[0]
    If $Str[$x] Then
        $Hex &= Chr((Dec($Str[$x])))
    EndIf
Next

MsgBox(0, "", "Click OK to start, make sure you have a packet scanner ready!")

$ReturnTCPStartup = TCPStartup()

$IP = TCPNameToIP("www.google.com")

$Socket = TCPConnect($IP,80)

TCPSend($Socket,$Hex)


MsgBox(0, "", "IP: " & $IP & @CRLF & "TCPStartup return: " & $ReturnTCPStartup & @CRLF & "Connected: "  & $Socket & @CRLF & "Message: " & $Hex)

This is just an example, and should be modified to fit whatever you need..

To do what you want to, you will need a lot of knowledge over AutoIt, TCP and Diablo II.

It's not easy, you would need to make a proxy based idea for it. It's fairly hard to inject using just autoit. Manadar's way would be a clientless bot which is very difficult, considering Warden will drop your games every 30 seconds.

This is in-game packet decompression. This code is based on a disassembly from fog.dll. Up to you to convert it to AutoIt
