    Creating a socket in PHP

    I am trying to open as many sockets I can against my mail server to test if it is prown to attack.

    I have tried to create 2000 sockets, but I can't seem to get it working and wondering if anyone knows whats going on?

    PHP Code:
    <?php
        $counter 
    0;
        
    createsocket:
        
    $socket socket_create(AF_INETSOCK_RAWtcp);
        
    socket_connect($socket"10.0.0.4"25);
        
    $counter++;
        if (
    $counter != 2000) {
            goto 
    createsocket;
        }
        
    sleep(240);
        
    socket_close($socket);
    ?>

    Use a while loop?

    PHP Code:
    <?php
    while ($i <= 2000) {
        
    $i++;

    createsocket:
        
    $socket socket_create(AF_INETSOCK_RAWtcp);
        
    socket_connect($socket"10.0.0.4"25);

    }

        
    sleep(240);
        
    socket_close($socket);



        
    ?>

    If you are running linux, which I presume you are then run the following command
    sysctl -a | grep somaxconn
    This will tell you the highest amount of sockets that can be open at the same time. By default your system is most likely 128.

    Its not telling me anything. I can see that it is opening a single connection, closing it, then opening the next.
    I am trying to have the connections all open at the same time.

    How about this:


    PHP Code:


    <?php

    $num 
    "0";

    while (
    $num <= "2000") {

    $num++;

    $fp fsockopen("10.0.0.4"25$errno$errstr30);
    if (!
    $fp) {
        echo 
    "$errstr ($errno)<br />\n";
    } else {
    echo 
    "Connected $num";

    }

    }
    ?>

    RAW sockets on *any* OS require root/admin user. http://linux.die.net/man/7/raw

    Guessing that might be your issue. Also don't use goto, bad.

    You may also have a file descriptor issue with that many connections.
