Anybody in /etc/passwd is logically a user, but in general ftp, mail, daemon, bin etc are system users, used by daemons(background processes, run ps aux) I dont have any idea about purpose of halt and shutdown users. Try man halt or man shutdown. >Can I halt without logging in ? You cant halt/reboot unless you login as root(superuser). You can however reboot by pressing ctrl-alt-del on local terminals OR switching the computer off ;-). Amish.
