Users Online is Unix compatible. Users Online displays 'there are currently X users online' on your webpage, as well as providing the current page of users on your site. View which page users are on, which pages they visited and how long they've been on your site. An alert is played every time a visitor hits your site so the page can be left minimised and brought up when someone enters. Also shows ip of the user, as well as the referring url. A great way to see where your visitors are coming from. Uses SSI.
