SYNOPSIS
       faillog [options]

DESCRIPTION
       faillog formats the contents of the failure log from /var/log/faillog
       database. It also can be used for maintains failure counters and
       limits. Run faillog without arguments display only list of user faillog
       records who have ever had a login failure.

OPTIONS
       The options which apply to the faillog command are:

       -a, --all
          Display faillog records for all users.

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

       -l, --lock-time SEC
          Lock account to SEC seconds after failed login.

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

       -r, --reset
          Reset the counters of login failures or one record if used with the
          -u LOGIN option. Write access to /var/log/faillog is required for
          this option.

       -t, --time DAYS
          Display faillog records more recent than DAYS. The -t flag overrides
          the use of -u.

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

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.
