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.
En mode affichage, toujours limitée aux utilisateurs existants, mais l'affichage des entrées d'erreur de connexion est imposé même si elles sont vides.
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
Afficher un message d'aide et quitter.
-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
Remettre à zéro le compteur d'échecs de connexion.
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).
AVERTISSEMENTS
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.
