1) To allow only FTP access to a share (AFP/FTP/SMB):
$ sharing -e sharename -s 010
2) All the configuration files are in /Library/FTPServer/Configuration 3) “man ftpaccess” had some useful info on the different chrootType values:
chroot_type standard | homedir | restricted Sets the type of restricted environment the user is under when he logs on. standard Allows users to access the ftp root, their homedir, and sharepoints. homedir Allows users to access the their homedir and sharepoints. restricted restricts users to their own home directory.
and they all work with serveradmin:
$ serveradmin settings ftp:chrootType = "HOMEDIR"
