[Dod:S only?] sb_debug_connection.php - not returning host name in UDP check

[DNA-styx]

What are the steps to reproduce this issue?

1. Use current 2.0.0 rc7 sb_debug_connection.php to check a Day of Defeat Source dedicated server

What happens?

host name not returned in UDP check

What were you expecting to happen?

With blow code change, host name is returned

Any logs, error output, etc.?

Any other comments?

only seems needed with DoD:S server,, TF2 servers return their hostname without the second step.

           if (strlen($packet) >= 9 && $packet[4] === "\x41") {
                $challenge = substr($packet, 5, 4);
                echo '<div class="log-line info">[+] Challenge received. Sending follow-up request...</div>';

                $query2 = "\xFF\xFF\xFF\xFF\x54Source Engine Query\0" . $challenge;
                $written2 = @fwrite($sock, $query2);

                if ($written2 === false) {
                    $errors[] = "udp_write_failed";
                    $error = error_get_last();
                    echo '<div class="log-line error">[-] Write error on challenge response: ' . $error['message'] . '</div>';
                } else {
                    $packet = fread($sock, 1480);
                }
            }

If it's just DoD, then the problem is with DoD really, we use the A2S protocol shared by many games and it's suppose to give us the hostname.
