I'm setting up a file share for a small group (CIFS/samba on FreeNAS, so the base system is FreeBSD/ZFS using ACLs). I want to allow users to put stuff into a folder on the share - but not to be able to read the share's contents once written. Since they can't read the shares contents or get directory listings, the share will be flat (no subdirectories) and they mustn't be able to overwrite or alter files that already exist unseen there, since they couldn't see them to avoid the overwrite and because it allows probing of filenames that exist or don't.Is there a way to do this?
