<sect2>Overview of module
|
||
|
|
|
||
|
|
<p>
|
||
|
|
This session module maintains the <tt>/var/log/wtmp</tt> file. Adding
|
||
|
|
an open entry when called via the <tt>pam_open_seesion()</tt> function
|
||
|
|
and completing it when <tt>pam_close_session()</tt> is called. This
|
||
|
|
module can also display a line of information about the last login of
|
||
|
|
the user. If an application already performs these tasks, it is not
|
||
|
|
necessary to use this module.

||
|
|
message. when the user logs into the system from what ever application

||
|
|

|
||
|
|
<tt>/var/log/wtmp</tt> file.
|
||
|
|
|
||
|
|
<p>
|

|
|
<itemize>
|

<item><tt/nodate/

This module can be used to indicate that the user has new mail when
|
||
|
|
they <em/login/ to the system. Here is a sample entry for your
|
||
|
|
<tt>/etc/pam.conf</tt> file:
|
||
|
|
<tscreen>
|
||
|
|
<verb>
|
||
|
|
#
|
||
|
|
# do we have any mail?
|
||
|
|
#
|
||
|
|
login session optional pam_lastlog.so
|
||
|
|
</verb>
|
||
|
|
</tscreen>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Note, some applications may perform this function themselves. In such
|
||
|
|
cases, this module is not necessary.
