faillog − mostra i conteggi e imposta i limiti degli accessi falliti

faillog [opzioni] |
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.
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.
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
Mostra un messaggio di aiuto ed esce.
−l, −−lock−secs SEC
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).
faillog mostra solo gli utenti che non hanno effettuato nessun accesso corretto dopo l'ultimo tentativo fallito. 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.
/var/log/faillog
