Dropbox has a prebuilt installer for ubuntu. Works with nautilus or even just command line, and is easy to install. It required a library that was not included with the Dropbox installer .deb package, but I was easily able to locate and install the missing library with the Synaptic Package Manager. I had to run the command "dropbox start -i" from the command line the first time to start up the Dropbox installer GUI, and load the dropbox daemon into memory. I am really getting into Dropbox, but IT has all Dropbox IP addresses blocked at my urgent care. I could just copy all my Dropbox files and folders to S3, but that's slower and unnecessary. With Dropbox autopopulating all the files and folders to my hylafax server, all I have to do is use WinSCP on Windows or ssh on Linux to connect to the hylafax server and upload/download files to these folders. I am not blocked from ssh at urgent care, so it works fine. Sure beats using a USB keydrive to copy files back and forth from the 3 machines I use at urgent care to make sure they get uploaded to my Dropbox folder.
