faillog [opzioni]

DESCRIZIONE

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.

OPZIONI

Il comando faillog accetta le seguenti opzioni:

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

-h, --help
    Mostra un messaggio di aiuto ed esce.

-l, --lock-timeSEC
    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, --timeGIORNI
    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.

Un utente che abbia completato correttamente un accesso dopo l'ultimo tentativo fallito è mostrato solo se viene richiesto esplicitamente con l'opzione -u o se viene richiesto di mostrare tutti gli utenti con l'opzione -a.
