pam_motd — Display the motd file
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
DESCRIPTION
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:
/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 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.
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

/run/motd

Each message size is limited to 64KB.
If /etc/motd does not exist, then /run/motd is shown. If /run/motd does not

Similar overriding behavior applies to the directories. Files in /etc/motd.d/

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.
