Имя (Name)

faillog - display faillog records or set login failure limits

---

Синопсис (Synopsis)

faillog [options]

---

Описание (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.

---

Параметры (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).

---

Предостережение (Caveat)

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.
