This is a fairly simple question, and I've been struggling at great length with it for no reason, so I decided just to post the question.
I have a FTP server with a bunch of users. They are all part of a group, ftp-users. I only want them to be able to access one folder, let's call it /home/folder. Currently, all users can access / and other folders.
In theory, if I run:
setfacl -x g:501 /
that should remove all permissions for the folder /, should it not? I just tried it and it didn't change anything.
