faillog − display faillog records or set login failure limits
|
faillog [options] |
faillog formats the contents of the failure log from /var/log/faillog database. It also can be used for maintains failure counters and limits. Run faillog without arguments display only list of user faillog records who have ever had a login failure.
The options
which apply to the faillog command are:
−a, −−all
Display faillog records for all users.
−h, −−help
Display help message and exit.
−l, −−lock−time SEC
Lock account to SEC seconds after failed login.
−m, −−maximum MAX
Set maximum number of login failures after the account is disabled to MAX. Selecting 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.
−r, −−reset
Reset the counters of login failures or one record if used with the −u LOGIN option. Write access to /var/log/faillog is required for this option.
−t, −−time DAYS
Display faillog records more recent than DAYS. The −t flag overrides the use of −u.
−u, −−user LOGIN
Display faillog record or maintains failure counters and limits (if used with −l, −m or −r options) only for user with LOGIN.
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.
