By default, pam_motd shows files in +the following locations: + +/etc/motd +/run/motd +/usr/lib/motd +/etc/motd.d/ +/run/motd.d/ +/usr/lib/motd.d/ + +Each message size is limited to 64KB. + +If /etc/motd does not exist, then /run/motd is shown. If /run/motd does not +exist, then /usr/lib/motd is shown. + +Similar overriding behavior applies to the directories. Files in /etc/motd.d/ +override files with the same name in /run/motd.d/ and /usr/lib/motd.d/. Files +in /run/motd.d/ override files with the same name in /usr/lib/motd.d/. + +Files the in the directories listed above are displayed in lexicographic order +by name. + +To silence a message, a symbolic link with target /dev/null may be placed in / +etc/motd.d with the same filename as the message to be silenced. Example: +Creating a symbolic link as follows silences /usr/lib/motd.d/my_motd. + +ln -s /dev/null /etc/motd.d/my_motd + +The MOTD_SHOWN=pam environment variable is set after showing the motd files, +even when all of them were silenced using symbolic links. + +OPTIONS + +motd=/path/filename + + The /path/filename file is displayed as message of the day. Multiple paths + to try can be specified as a colon-separated list. By default this option + is set to /etc/motd:/run/motd:/usr/lib/motd. + +motd_dir=/path/dirname.d + + The /path/dirname.d 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 /etc/motd.d:/run/ + motd.d:/usr/lib/motd.d. + +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. + +EXAMPLES + +The suggested usage for /etc/pam.d/login is: + +session optional pam_motd.so + + +To use a motd file from a different location: + +session optional pam_motd.so motd=/elsewhere/motd + + +To use a motd file from elsewhere, along with a corresponding .d directory: + +session optional pam_motd.so motd=/elsewhere/motd motd_dir=/elsewhere/motd.d + + +AUTHOR + +pam_motd was written by Ben Collins <bcollins@debian.org>. + +The motd_dir= option was added by Allison Karlitskaya +<allison.karlitskaya@redhat.com>. + diff --git a/modules/pam_motd/README.xml b/modules/pam_motd/README.xml new file mode 100644 index 0000000..779e4d1 --- /dev/null +++ b/modules/pam_motd/README.xml @@ -0,0 +1,41 @@ +<?xml version="1.0" encoding='UTF-8'?> +<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.3//EN" +"http://www.docbook.org/xml/4.3/docbookx.dtd" +[ +<!-- +<!ENTITY pamaccess SYSTEM "pam_motd.8.xml"> +--> +]> + +<article> + + <articleinfo> + + <title> + <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" + href="pam_motd.8.xml" xpointer='xpointer(//refnamediv[@id = "pam_motd-name"]/*)'/> + </title> + + </articleinfo> + + <section> + <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" + href="pam_motd.8.xml" xpointer='xpointer(//refsect1[@id = "pam_motd-description"]/*)'/> + </section> + + <section> + <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" + href="pam_motd.8.xml" xpointer='xpointer(//refsect1[@id = "pam_motd-options"]/*)'/> + </section> + + <section> + <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" + href="pam_motd.8.xml" xpointer='xpointer(//refsect1[@id = "pam_motd-examples"]/*)'/> + </section> + + <section> + <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" + href="pam_motd.8.xml" xpointer='xpointer(//refsect1[@id = "pam_motd-author"]/*)'/> + </section> + +</article> |
