Overview

This module allows to generate a dynamic Motd /var/run/motd with simples scripts.

Module Description

This is a simple Puppet module to manage a more advanced Motd (Message of the day) and automatically display it upon successful ssh or shadow login.

Setup

What dynmotd affects

  • Dynamic (/var/run/motd) and static (/etc/motd) Motd files.
  • The dynamic Motd generation directory and scripts (/etc/update-motd.d).
  • The pam configuration to display the Motd for ssh and shadow login.

Usage

To begin using Motd module with defaults parameters:

include dynmotd

If you don't want to display the Motd upon ssh login:

class { 'motd':
  print_motd_ssh => false,
}

Limitations

This module has only be tested on Debian 7.x versions, but should work on Debian >7. The dynamic Motd generation with /etc/update-motd.d directory was implemented in pam by Ubuntu (in 10.04), so it should also work with Ubuntu >=10.04.
