FTP users prevent browsing to other directories
I've installed my first fedora box to use as a ftp server for my network, locally and public. For the public users they will be redirected to the /var/ftp/pub/ directory, and have upload and download permissions.
What i would like to prevent is that these users are able to browse to the upper directories in the tree.
I've added the users for public ftp only to the ftp group, but still they are able to browse to the etc directory and download my config files.
how do i prevent this from happening?
thanks a lot for your help.
