Opera Unite alpha lets you share files -- but is it safe?
Opera Software's announcement that it's going to bundle Unite, an easy-to-use Web server with content-sharing applets, with the Opera 10 Web browser sounds great -- at first. Upon closer inspection, though, there could be some real security headaches.
For now, Unite, which is available for Linux, Mac OS X and Windows, is alpha software. That means it breaks. A lot. (I experienced a number of disconnects and freezes.) Still, I was able to get it to work on systems running Windows XP and SimplyMepis 8.0, a Debian Linux distribution.
To make this happen, your PC and its Internet connection have to have port 8840 open. To let others get to your computer, you tell them your Unite URL.
