woleium Posted May 18, 2009 Posted May 18, 2009 (edited) Hello everyone! I can't work out how to determine the connecting client IP when using the TCPStartup() function I'd like to limit connections based on IP, so if someone connects with the wrong IP the session is disconnected. Any ideas? Edited May 18, 2009 by woleium
FreeFry Posted May 18, 2009 Posted May 18, 2009 (edited) Have you tried searching the forum? I'm fairly sure I've seen a function that does what you want somewhere in here.Edit:Here you go:Func _TCPSocketToIP(ByRef $ivOSocket) Local $stvSockAddr = DllStructCreate("short;ushort;ptr;char[8]") Local $avResult = DllCall("Ws2_32.dll", "int", "getpeername", "int", $ivOSocket, "ptr", DllStructGetPtr($stvSockAddr), "ptr*", DllStructGetSize($stvSockAddr)) If Not IsArray($avResult) Or (IsArray($avResult) And $avResult[0]) Then Return(SetError(1, 0, 0)); Something went wrong $avResult = DllCall("Ws2_32.dll", "str*", "inet_ntoa", "ptr", DllStructGetData($stvSockAddr, 3)) If Not IsArray($avResult) Or (IsArray($avResult) And Not $avResult[0]) Then Return(SetError(2, 0, 0)); Something else went wrong Return $avResult[0] EndFuncAn example of how to use it:TCPStartup() Dim $ioSocket = TCPConnect(TCPNameToIP("www.google.com"), 80) If $ioSocket = -1 Then Exit; Could not open socket ConsoleWrite(_TCPSocketToIP($ioSocket) & @LF) TCPCloseSocket($ioSocket) TCPShutdown() Func _TCPSocketToIP(ByRef $ivOSocket) Local $stvSockAddr = DllStructCreate("short;ushort;ptr;char[8]") Local $avResult = DllCall("Ws2_32.dll", "int", "getpeername", "int", $ivOSocket, "ptr", DllStructGetPtr($stvSockAddr), "ptr*", DllStructGetSize($stvSockAddr)) If Not IsArray($avResult) Or (IsArray($avResult) And $avResult[0]) Then Return(SetError(1, 0, 0)); Something went wrong $avResult = DllCall("Ws2_32.dll", "str*", "inet_ntoa", "ptr", DllStructGetData($stvSockAddr, 3)) If Not IsArray($avResult) Or (IsArray($avResult) And Not $avResult[0]) Then Return(SetError(2, 0, 0)); Something else went wrong Return $avResult[0] EndFunc Edited May 18, 2009 by FreeFry
