Being in a lot of hotels and other wifi areas I always try to keep everything I've got locked down tight. I try not to share anything, but I'm constantly amazed how many other shared folders pop up in my finder and do my best to not go snooping. Just tonight I saw one pop up as I plugged in and for whatever reason I decided to click on it, the guy had his whole desktop directory and a bunch of folders below it shared, including music and movies. And some not so well hidden private stuff was in the movies directory I should add =P But the reason I ask, is that it seems that Dropbox by default wants to put a public directory up, and it uses the machine owner's name for the shared roll up. Last thing I need is any name of my machine showing due to dropbox, let alone my full name. So without having a second machine to pop onto the network (other than an iPhone in a pinch), how do I see what I'm leaking? Any ideas for locking down tighter in general on OSX would be appreciated.
