TCP checking open ports

Recommended Posts

XTensionX

Hi how can I check if a port is open, im still pretty new to the TCP stuff.

I've tried TCPListen but that would interupt the connection if the port is in use.

I don't want the program to connect to it, I just want to check if the port is open.

Here is what I've tried:

TCPStartup()
Local $MainSocket = TCPListen("127.0.0.1", 65432)
TCPShutdown()
If $MainSocket = -1 Then
   MsgBox(0,"", "No")
Else
   MsgBox(0,"", "Open")
EndIf

and

TCPStartup()
$socket = TCPConnect($g_IP, 65432)
If $socket = -1 Then
   MsgBox(0,"", "No")
Else
   MsgBox(0,"", "Open")
EndIf

thanks

You could have a look at trancexx's So you can get a list of all ports in use and then check the rest.

Thanks, It seems like what I'm looking for.
