faillog - mostra le registrazioni e imposta i limiti degli accessi falliti
SINOSSI
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
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. 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. Write access to /var/log/faillog is required for this option. -r, --reset Azzera i contatori degli accessi falliti. 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).
AVVISI/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.
