Error on Custom Logout page

  • Hello all,

    I created a, working, solution for our users to manually logout if they logon to their second/third/fourth/etc.. device.
    They will be shown a list of client devices (ip addresses) and they select one to be logged out, I used the default logout code from the default logout popup window.

    As I don't wanna modify the core files, I made this all work with the default 'Error page'.

    Most important things done:

    /* code */

    global $cpzone, $cpzoneid;

    $cpzone = $_REQUEST['zone'];
    $cpcfg = $config['captiveportal'][$cpzone];

    $cpzoneid = $cpcfg['zoneid'];

    $orig_host = $_SERVER['HTTP_HOST'];
    /* NOTE: IE 8/9 is buggy and that is why this is needed */
    $orig_request = trim($_REQUEST['redirurl'], " /");
    $clientip = $_SERVER['REMOTE_ADDR'];
    $username = $_REQUEST['auth_user'];
    $password = $_REQUEST['auth_pass'];
    $bpassword = base64_encode($password);

    // Search for entries in CP db.
    $cpdb = captiveportal_read_db("WHERE username='{$username}' AND bpassword='{$bpassword}'");

    /* code for layout */
    if (count($cpdb) == 1) {
    // single entry and failure means, a user can only logon once.
    // Action: disconnect user and let them login again.
    captiveportal_disconnect_client($cpdb[0]['sessionid'], 1, $logoutReason = "User LOGOUT - on First device !!");
    echo "

    Other device disconnected, you can logon again!

    } else {
    // multiple entries found, meaning user has to choose which session to kill.
    for ($i=0; $i <count($cpdb);$i++){ <br="">if ($i==0) { echo "

    choose your device to disconnect:

    "; }
    /* code for layout */

    /* code for layout */

    /* code for layout */

    The issue I'm having is that the bold line results in the following error (first time):
    Failed setsockopt
    Second time(meaning the user is logged out I think):
    Failed setsockoptFailed setsockopt Warning: Cannot modify header information - headers already sent by (output started at /etc/inc/ in /etc/inc/ on line 1757

    I tried a lot to get this fixed, but can't seem to pinpoint the real issue here.

    Anybody got any idea why I keep getting this issue?

    Thank you!

  • Hi Gertjan,

    thank you for your reply, I searched the forum, did not found this (your) reply as you' re pointing out.
    This helped me solve the puzzle!



  • Hi Everyone,
    I have been looking for a custom logout page for 2.2.4 but I could not find one. What I've been using in my setup is this tutorial but it is only usable only for 2.1.5 "". Can you share some ideas on this?
    Thank you.
