Friday Favorites: Using Little Snitch to stop apps from phoning home
One thing that drives me mad is when applications try to phone home with information. Usually, these requests are benign; the app is either looking for the latest update or making a serial number verification request. If it's a rogue app, though, it could be sending back information you'd rather not share. To find out which apps are phoning home, you can install Little Snitch. It's a US$30 app that alerts you whenever a program tries to establish an outgoing Internet connection. You can choose to block this connection, or let it through on a case-by-case basis. You can also specify a rule to handle this connection attempt in the future, so you don't have to be alerted each time the app phones home again. Little Snitch gives you fine control over these connection attempts. Besides permanently blocking a connection, you can also choose to stop it for a single session. This session-based blocking is convenient for travelers who are using a cellular connection and want to limit their data consumption. Little Snitch is an excellent app for tracking your outgoing Internet connection. You'd be surprised by the number of apps that try to phone home and how often they do it. Google Chrome is one of the worst offenders in this group as it tries to connect to the Google mothership several times a day. If you want to try it out yourself, there's a limited time trial of Little Snitch that runs for a 3 hours at a time. The full, unlimited app costs $30 and is available from Objective Development's website.
Little Snitch updated to 2.0, Leopard compatible
Macworld brings news that everyone's favorite tattletale, Little Snitch, has been updated to version 2.0. The new version brings a whole host of updates, including a new Network Monitor, which will let you know about all outgoing and incoming network traffic. There's also support for IPV6, and a better help and traffic filtering system. Oh, and perhaps most importantly, the whole thing's been overhauled and is now compatible with a little thing called Leopard. I haven't upgraded yet, but considering those other "next-gen" operating systems, I'm not sure if I should.Little Snitch 1 users may be able to upgrade for free (if your version number starts with "32"), if not you pay a discounted rate. If you haven't started using Little Snitch yet, you can try the eval version, or pay $24.95 for the full app. If you have a lot of network traffic coming in and out of your Mac, you might want to consider it-- how else will you know what's coming through there?
