OS X Lion FTP Server

For those of you that occasionally need an FTP Server on the fly you'll notice that the option to enable it is no longer immediately available in OS X Lion's System Preferences. Thankfully there's a way to enable and disable it via the command line.

sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist
sudo -s launchctl unload -w /System/Library/LaunchDaemons/ftp.plist
