NAME¶
pam_lastlog - PAM module to display date of last login and perform inactive account lock outSYNOPSIS¶
pam_lastlog.so [debug] [silent] [never] [nodate] [nohost]
[noterm] [nowtmp] [noupdate] [showfailed] [inactive=<days>]
DESCRIPTION¶
pam_lastlog is a PAM module to display a line of information about the last login of the user. In addition, the module maintains the /var/log/lastlog file. Some applications may perform this function themselves. In such cases, this module is not necessary. If the module is called in the auth or account phase, the accounts that were not used recently enough will be disallowed to log in. The check is not performed for the root account so the root is never locked out.OPTIONS¶
debugPrint debug information.
silent
Don't inform the user about any previous login, just
update the /var/log/lastlog file.
never
If the /var/log/lastlog file does not contain any old
entries for the user, indicate that the user has never previously logged in
with a welcome message.
nodate
Don't display the date of the last login.
noterm
Don't display the terminal name on which the last login
was attempted.
nohost
Don't indicate from which host the last login was
attempted.
nowtmp
Don't update the wtmp entry.
noupdate
Don't update any file.
showfailed
Display number of failed login attempts and the date of
the last failed attempt from btmp. The date is not displayed when
nodate is specified.
inactive=<days>
This option is specific for the auth or account phase. It
specifies the number of days after the last login of the user when the user
will be locked out by the module. The default value is 90.
