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
The options which apply to the faillog command are: -a, --allDisplay (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.
Nella modalità di visualizzazione, questo è già ristretto
ai soli utenti esistenti, ma vengono mostrate anche eventuali registrazioni
vuote.
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, --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.

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).
