TCP question

[d0n]

For my script i was able to use TCPConnect and then TCPSend something to the server and its working .

$socket = TCPConnect($ip, $port)

However I am trying to find a way to listen to an existing socket, but TCPListen doesn't work for some reason.

$socket = TCPListen($ip, $port, 5000)

Both of them are using the same IP and port but TCPListen is returning a -1 error

please tell me what i am doing wrong

Well nothing should be wrong as we can't see what is wrong because there is no code for us to prove that something is wrong.

Hi

Code that works if i start the client with autoit, i can receive the packets back

TCPStartup()

$socket = TCPConnect($ip, $port)


ConsoleWrite("SOCKET: "&$socket&@LF)

If $socket = -1 Then Exit


While 1
    $recv = TCPRecv ($socket, 5000)
    If $recv <> "" Then
        ConsoleWrite($recv&@CRLF)
    EndIf
WEnd
TCPShutdown()

Code that doesn't work if the client is already started and talking to the server, can't get a socket

TCPStartup()

$socket = TCPListen($ip, $port, 100)


ConsoleWrite("SOCKET: "&$socket&@LF)

If $socket = -1 Then Exit


While 1
    $recv = TCPRecv ($socket, 5000)
    If $recv <> "" Then
        ConsoleWrite($recv&@CRLF)
    EndIf
WEnd
TCPShutdown()

Have you tried Kips' Event Driven UDP http://www.autoitscript.com/forum/index.php?showtopic=74325 it makes life a lot easier with TCP.

Just read the freaking help file TCPRecv() page.

Its not that i can't recv, I can't even get a socket to the connection

And the I am not hosting the server, just trying to read some packets sent between THEIR server, and MY client (i think kip's UDF only works with my server/ my client, correct me if i am wrong here, might of missed something in there)

=,= """"

You can't just "read some packets" between THAT server and YOUR client directly with autoit.

And each port could only assign to 1 program.

what is it you are trying to do??

No you are correct. I thought from your first message it was a client-server system you were setting up.

Maybe you should add a bit of detail so everyone is on the same page?

He's trying to create a packet sniffer?

[d0n]

yes i guess you can call it a packet sniffer, is this possible with autoit?

EDIT: Got it working with WinPcap, thank you!
