NAMN

       faillog - display faillog records or set login failure limits

SYNOPSIS

       faillog [flaggor]

BESKRIVNING

       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.

FLAGGOR

       Flaggorna som gäller för kommandot faillog är:

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

       -h, --help
           Visa hjälpmeddelande och avsluta.

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

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

       -m, --maximumMAX
           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.

       -t, --timeDAGAR
           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).

       NOTE: in display mode, only the records of users which currently exist
       in the system are displayed. In the other modes (when the -l, -m, or -r
       options are used), the records of the user, or the range of users, or
       all the users that may have an entry in the faillog database will be
       changed. This is useful to reset records of users that have been
       deleted or set a policy in advance for a range of users.

TÄNK

       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.

FILER

       /var/log/faillog
           Failure logging file.
