NAME
       faillog - display faillog records or set login failure limits

SYNOPSIS
       faillog [options]

DESCRIPTION
       faillog displays the contents of the failure log database
       (/var/log/faillog). It can also set the failure counters and limits.
       When faillog is run without arguments, it only displays the faillog
       records of the users who had a login failure.

OPTIONS
       The options which apply to the faillog command are:

       -a, --all
	   Display (or act on) faillog records for all users having an entry
	   in the faillog database.

	   The range of users can be restricted with the -u option.

	   In display mode, this is still restricted to existing users but
	   forces the display of the faillog entries even if they are empty.

	   With the -l, -m, -r, -t options, the users' records are changed,
	   even if the user does not exist on the system. This is useful to
	   reset records of users that have been deleted or to set a policy in
	   advance for a range of users.

       -h, --help
	   Display help message and exit.

       -l, --lock-secs SEC
	   Lock account for SEC seconds after failed login.

	   Write access to /var/log/faillog is required for this option.

       -m, --maximum MAX
	   Set the maximum number of login failures after the account is
	   disabled to MAX.

	   Selecting a MAX value of 0 has the effect of not placing a limit on
	   the number of failed logins.

	   The maximum failure count should always be 0 for root to prevent a
	   denial of services attack against the system.

	   Write access to /var/log/faillog is required for this option.

       -r, --reset
	   Reset the counters of login failures.

	   Write access to /var/log/faillog is required for this option.

       -R, --root CHROOT_DIR
	   Apply changes in the CHROOT_DIR directory and use the configuration
	   files from the CHROOT_DIR directory.

       -t, --time DAYS
	   Display faillog records more recent than DAYS.

       -u, --user LOGIN|RANGE
	   Display faillog record or maintains failure counters and limits (if
	   used with -l, -m or -r options) only for the specified user(s).

	   The users can be specified by a login name, a numerical user ID, or
	   a RANGE of users. This RANGE of users can be specified with a min
	   and max values (UID_MIN-UID_MAX), a max value (-UID_MAX), or a min
	   value (UID_MIN-).

       When none of the -l, -m, or -r options are used, faillog displays the
       faillog record of the specified user(s).

CAVEATS
       faillog only prints out users with no successful login since the last
       failure. To print out a user who has had a successful login since their
       last failure, you must explicitly request the user with the -u flag, or
       print out all users with the -a flag.

FILES
       /var/log/faillog
	   Failure logging file.
