Need some help: Patch to show usernames without authentication used to work but doesn't work anymore.

  • Hey everyone,
    I’m here to ask for some help. I’ve got this scenario where I want to be able to capture the usernames that people enter in the captive portal without authentication.
    Someone wrote a patch for it years ago that modifies the portal to do exactly that but sadly I can’t get that to work anymore.This thread sums up exactly what I want to do and has the patch listed too.
    Would really appreciate some help from people more experienced than I am on this subject matter.

  • Hi,

    That code still works, although the diff file is old so it can't patched in using the patch command against a recent /usr/local/captiveportal/index.php file.

    Change (nearly to the bottom of the index.php file) :

    } else if ($_POST['accept'] && $clientip && $cpcfg['auth_method'] == "none") {
    	captiveportal_logportalauth("unauthenticated", $clientmac, $clientip, "ACCEPT");
    	portal_allow($clientip, $clientmac, "unauthenticated");
    } else {


    } else if ($_POST['accept'] && $clientip && $cpcfg['auth_method'] == "none") {
    	$user = "unauthenticated"; // or $user = "Unknown - no USER name entered";
    	if ($_POST['auth_user'])
    		$user = $_POST['auth_user'];
        captiveportal_logportalauth($user, $clientmac, $clientip, "ACCEPT");
        portal_allow($clientip, $clientmac, $user);
    } else {

    I didn't test-drive this code.

    edit : See this (proposed in the much bigger )
