This How-to will explain how to restrict your FTP users to their home directory, so they won't be able to look at any directories higher than their own. Launch Terminal (in Applications -> Utilities) type: cd /etc sudo pico ftpchroot Type the valid usernames of people in this file that you want to be restricted to their own directory when they FTP into their machine. Separate each entry by a carriage return. This file will look simply like this: ebunny sclaus tfairy Then save the file by holding down the Control key and hitting X. This will create the file ftpchroot in the /etc directory. Now restart your FTP server by turning it off then on again in your Sharing Control panel. Done!
