## 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,
}
```

## Reference

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.
