Timeoutd enforces the time restrictions specified for each or all users.

timeoutd scans /var/run/utmp every minute and checks /etc/timeouts for an entry which matches a restricted user, based on:

- the current day and time
- the tty that the user is currently logged in on
- the user's login id
- any primary or secondary groups the user is in
timeoutd can restrict local users, x11-users and users via telnet/ssh for a maximum of their session, max. day, idle or no login at all.

timeoutd is also able to restrict users running x.
