pam_motd: Display the motd file

NAME

pam_motd - Display the motd file

SYNOPSIS

pam_motd.so [motd=/path/filename]

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 the /etc/motd file is shown. The message size is limited to 64KB.

OPTIONS

motd=/path/filename

The /path/filename file is displayed as message of the day.

motd_dir=/path/dirname.d

The /path/dirname.d directory is scanned and each file contained inside of it is displayed.

noupdate

Don't run the scripts in /etc/update-motd.d to refresh the motd file.

When no options are given, the default is to display both /etc/motd and the contents of /etc/motd.d. Specifying either option (or both) will disable this default behavior.

The MOTD_SHOWN=pam environment variable is set after showing the motd files, even when all of them were silenced using symbolic links.

MODULE TYPES PROVIDED

Only the session module type is provided.

RETURN VALUES

PAM_ABORT

Not all relevant data or options could be obtained.

PAM_BUF_ERR

Memory buffer error.

PAM_IGNORE

This is the default return value of this module.

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
