    Hi,

    I'm trying to get some PICED logic to open a client socket through Socket I/O to a local server socket I've setup but PICED refuses to open a connection no matter what I try.

    I searched the forums and I found an old post saying all ports were blocked but then something about the possibility of opening the ports in the future. I then found posts about modifying some CTC firewall settings but I'd like to try the code out locally before updating a CTC.

    Is there something I can do inside PICED to open client sockets?

    Thanks,
    Jamie

    The guru is on holiday this week.

    But...

    You don't make it clear - you want to open sockets in PICED and transfer this logic code to a CTC later?

    Or you want PICED to talk to a CTC via a socket?

    For PICED you should just be able to do it, make sure your firewall allows those sockets to be opened.

    For CTC there is a utility available which lets you open up a socket (in the network settings from memory). Socket ranges on the CTC are restricted, I think from memory the range is 20000 to 29999 or something like that.

    When you find the socket-opener-upper in the CTC it will tell you what the limits are.

    Hi Ashleigh,

    For the moment, I just want PICED to connect to a local socket server I've setup. I've setup a server app and it just sits there waiting for a connection. Unfortunately, PICED barfs after the OpenClientSocket command and no connection is ever made. No matter what port I use for both the server and PICED, I get Error number 4 "The connection could not be completed."

    Thanks,
    Jamie

    Can you connect to the server using other software?

    Yep, I wrote a client app and it works no problem. The technology is .NET (I've used both v1.1 and 2.0 with no difference).

    Thanks,
    Jamie

    It should just work... here's a snippet of code that works for me in PICED, talking to Slimserver running on another machine on my local network:

    In the initialisation bit :

    Code:
    OpenClientSocket('192.168.0.2', 9090); {open CLI connection to Slimserver}
    then later :
    Code:
    if ClientSocketConnected then
  begin
    WriteClientSocket('login {username} {password}'#10); {need to login if security enabled}
    delay(0.2);
    {enable notifications, whatever we terminate this string with is what the server will terminate its replies with}
    WriteClientSocket('listen 1'#10);
  end;

    I tried putting the Socket server on remote machine (actually a Microsoft Virtual PC image) and it worked. When I move the server application back to the same machine as PICED, the errors occur again.

    It looks like PICED will not work with a local server application.

    Cheers,
    Jamie

    Should not make any difference - local or remote, its all the same. It's not PICED, its something in your machine configuration.

    What are you using as you host? 127.0.0.1 or localhost or <network ip>

    I tried both addresses, network IP and localhost. Neither worked.

    However, once I installed the Microsoft Loopback Adapter locally and used the IP address assigned to the Loopback adapter, I was able to get PICED working locally.

    Cheers,
    Jamie
