title: Restrict pure-ftpd specific directory
body: <p>Currently I have a directory where FTP users are able to access, named /data. In /data, there are /data/folder1, /data/folder2, /data/folder3. My question is can I make use of pure-ftpd (in Ubuntu 14.04) to restrict such that the FTP users are only able to enter /data/folder2? I do not mind if they can view all the directories, but I need to make sure all FTP users have no privilege to enter /data/folder1 and /data/folder3. I appreciate if there are any suggestions.</p>
