Please look below for a more advanced login script

Heres a quick little tip to save some time looking at the ISPConfig login.php file, or for those who don't know php/html very well

<form method="POST" action="http://YOUR_DOMAIN_HERE:81/login/login.php">
  Username: <input type="text" name="username" size="15" /><br />
  Password: <input type="password" name="passwort" size="15" /><br />
  <div align="center">
    <p><input type="submit" value="Login" /></p>
  </div>
</form>

This is just some simple HTML code that will log in to the ISPConfig panel from anywhere you want to put it. (It will redirect you to the port 81 server, of course, but it will skip the login screen... supposing you put in a valid username and password.)

Also, note that "passwort" is not a typo. ISPConfig seemingly was not coded in english.

Hope this helps someone,
