• Socket Test

    From MCMLXXIX@MDJ to Deuce on Tuesday, April 29, 2008 18:47:02
    Ok, so I messed with the code you sent me a little, and tried it using
    both "127.0.0.1" with port 5000 + bbs.node_num
    and "127.0.0." + bbs.node_num with port 5000

    both had the same result, listen error: 45
    but there didn't seem to be a problem binding them either way

    here's the code.. it's spammy
    I didn't really expect it to work, since I'm half guessing, but I thought I was on the right track.. maybe not.

    load("sockdefs.js");
    load("sbbsdefs.js");
    load("nodedefs.js");

    var stream=new Socket(SOCK_DGRAM, "InterNode");
    main();

    function main()
    {
    if(!stream.bind(9000+bbs.node_num, "127.0.0.1")) {
    writeln("Bind failed: "+stream.error);
    exit(1);
    }
    else
    {
    if(ConnectionListener()) Chat();
    else exit(1);
    }
    }
    function Chat()
    {
    //Receive();
    writeln("Test connection successful");
    exit(0);
    }
    function ConnectionListener()
    {
    write("Waiting for users to connect");
    for(i=0;i<10;i++)
    {
    for(node in system.node_list) {
    stream.sendto("ping","127.0.0.1",9000 + node);
    }
    if(stream.listen()) return true;
    if(console.inkey().toUpperCase()=="Q") exit(1);
    mswait(250);
    write(".");
    }
    writeln("\r\nListen failed: "+stream.error);
    exit(1);
    }

    Heh, whoops, mixing my protocols there. You don't listen() for UDP since it's connectionless.

    Remove the listen() call and all should be good.

    Here's the code updated to do it both ways:
    load("sbbsdefs.js");
    load("sockdefs.js");

    var base_port=5000;
    var use_ports=true;

    var s=new Socket(SOCK_DGRAM, "InterNode");

    var bind_addr="127.0.0.";
    var bind_port=base_port;
    if(use_ports) {
    bind_addr += "1";
    bind_port += bbs.node_num - 1;
    }
    else {
    bind_addr += bbs.node_num;
    }

    if(!s.bind(bind_port, bind_addr)) {
    writeln("Bind to "+bind_addr+":"+bind_port+" failed: "+s.error);
    exit(1);
    }

    writeln("Q to quit or # to send message to node");

    while(1) {
    var k=console.inkey(100);
    if(k.toUpperCase()=='Q')
    break;

    if(parseInt(k)>0) {
    console.write(": ");
    var msg=console.getstr("", 77);
    var port=base_port;
    var addr="127.0.0.";
    if(use_ports) {
    port += parseInt(k)-1;
    addr += '1';
    }
    else {
    addr += k;
    }

    s.sendto(msg, addr, port);
    }

    if(s.data_waiting) {
    var d;
    d=s.recvfrom();
    writeln("Message from "+d.ip_address+":"+d.port);
    writeln(d.data);
    writeln("");
    }
    }

    Is there a way to tell if there is anyone on the receiving end? I.E. if you're the only one trying to run the engine it will either wait for someone to connect, or kick you out. I guess I can make it send a "yo! I'm here!" message when anyone runs it.

    Not with UDP... with TCP this is possible.
