\fBfaillog\fR [\fIoptions\fR]
.SH "DESCRIPTION"
.PP
\fBfaillog\fR
displays the contents of the failure log database (/var/log/faillog)\&. It can also set the failure counters and limits\&. When
\fBfaillog\fR
is run without arguments, it only displays the faillog records of the users who had a login failure\&.
.SH "OPTIONS"
.PP
The options which apply to the
\fBfaillog\fR
command are:
.PP
\fB\-a\fR, \fB\-\-all\fR

option\&.

.sp
With the
\fB\-l\fR,
\fB\-m\fR,
\fB\-r\fR,
\fB\-t\fR
options, the users\*(Aq 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\&.

\fB\-m\fR, \fB\-\-maximum\fR\ \&\fIMAX\fR
.RS 4
Set the maximum number of login failures after the account is disabled to
\fIMAX\fR\&.
.sp
Selecting a
\fIMAX\fR
value of 0 has the effect of not placing a limit on the number of failed logins\&.
.sp
The maximum failure count should always be 0 for
\fIroot\fR
to prevent a denial of services attack against the system\&.
.sp
Write access to
/var/log/faillog
is required for this option\&.
.RE
.PP
\fB\-r\fR, \fB\-\-reset\fR

\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&. Only absolute paths are supported\&.
.RE
.PP
\fB\-t\fR, \fB\-\-time\fR\ \&\fIDAYS\fR
.RS 4
Display faillog records more recent than
\fIDAYS\fR\&.
.RE
.PP
\fB\-u\fR, \fB\-\-user\fR\ \&\fILOGIN\fR|\fIRANGE\fR
.RS 4
Display faillog record or maintains failure counters and limits (if used with
\fB\-l\fR,
\fB\-m\fR
or
\fB\-r\fR
options) only for the specified user(s)\&.
.sp
The users can be specified by a login name, a numerical user ID, or a
\fIRANGE\fR
of users\&. This
\fIRANGE\fR
of users can be specified with a min and max values (\fIUID_MIN\-UID_MAX\fR), a max value (\fI\-UID_MAX\fR), or a min value (\fIUID_MIN\-\fR)\&.
.RE
.PP
When none of the
\fB\-l\fR,
\fB\-m\fR, or
\fB\-r\fR
options are used,
\fBfaillog\fR
displays the faillog record of the specified user(s)\&.
.SH "AVERTISSEMENTS"
.PP
\fBfaillog\fR
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
\fB\-u\fR
flag, or print out all users with the
\fB\-a\fR
flag\&.
.SH "FICHIERS"
.PP
/var/log/faillog
.RS 4
