ОПИСАНИЕ
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.
ПАРАМЕТРЫ
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.
В режиме вывода это ограничивает вывод списком существующих
пользователей, но при этом для них выводятся даже пустые записи
faillog.
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
Показать краткую справку и закончить работу.
-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
Сбросить счётчик неудачных попыток входа.
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. Only absolute paths are
supported.
-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).
ПРЕДОСТЕРЕЖЕНИЯ
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.
