DESCRIPTION</h3></div></div></div><p> pam_motd is a PAM module that can be used to display arbitrary motd (message of the day) files after a successful login. By default, pam_motd shows files in the following locations: </p><p> </p><table border="0" summary="Simple list" class="simplelist"><tr><td><code class="filename">/etc/motd</code></td></tr><tr><td><code class="filename">/run/motd</code></td></tr><tr><td><code class="filename">/usr/lib/motd</code></td></tr><tr><td><code class="filename">/etc/motd.d/</code></td></tr><tr><td><code class="filename">/run/motd.d/</code></td></tr><tr><td><code class="filename">/usr/lib/motd.d/</code></td></tr></table><p> </p><p> Each message size is limited to 64KB. </p><p> If <code class="filename">/etc/motd</code> does not exist, then <code class="filename">/run/motd</code> is shown. If <code class="filename">/run/motd</code> does not exist, then <code class="filename">/usr/lib/motd</code> is shown. </p><p> Similar overriding behavior applies to the directories. Files in <code class="filename">/etc/motd.d/</code> override files with the same name in <code class="filename">/run/motd.d/</code> and <code class="filename">/usr/lib/motd.d/</code>. Files in <code class="filename">/run/motd.d/</code> override files with the same name in <code class="filename">/usr/lib/motd.d/</code>. </p><p> Files in the directories listed above are displayed in lexicographic order by name. Moreover, the files are filtered by reading them with the credentials of the target user authenticating on the system. </p><p> To silence a message, a symbolic link with target <code class="filename">/dev/null</code> may be placed in <code class="filename">/etc/motd.d</code> with the same filename as the message to be silenced. Example: Creating a symbolic link as follows silences <code class="filename">/usr/lib/motd.d/my_motd</code>. </p><p> <span class="command"><strong>ln -s /dev/null /etc/motd.d/my_motd</strong></span> </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="sag-pam_motd-options"></a>6.21.2.

Multiple paths to try can be specified as a colon-separated list. By default this option is set to <code class="filename">/etc/motd:/run/motd:/usr/lib/motd</code>. </p></dd><dt><span class="term"> <code class="option">motd_dir=<em class="replaceable"><code>/path/dirname.d</code></em></code> </span></dt><dd><p> The <code class="filename">/path/dirname.d</code> directory is scanned and each file contained inside of it is displayed. Multiple directories to scan can be specified as a colon-separated list. By default this option is set to <code class="filename">/etc/motd.d:/run/motd.d:/usr/lib/motd.d</code>. </p></dd></dl></div><p> When no options are given, the default behavior applies for both options. Specifying either option (or both) will disable the default behavior for both options. </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="sag-pam_motd-types"></a>6.21.3.
