Introduction
------------

LibreNMS is an autodiscovering PHP/MySQL/SNMP based network monitoring
which includes support for a wide range of network hardware and operating
systems including Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP and
many more.  LibreNMS is a community-based fork of [Observium][9].

We intend LibreNMS to be a viable project and community that:
- encourages contribution,
- focuses on the needs of its users, and
- offers a welcoming, friendly environment for everyone.

The [Debian Social Contract][10] will be the basis of our priority system,
and mutual respect the basis of our behaviour towards others.  For more
about the culture we're trying to build, please read the [Freenode
philosophy][13], including [guidelines for running an IRC channel][6] and
[being a community catalyst][7].


Documentation
-------------

Documentation can be found in the [doc directory][5] or [docs.librenms.org][16], including instructions
for installing and contributing.


Participating
-------------

You can participate in the project by:
- Joining the [librenms-project][1] mailing list to post questions and
  suggestions.
- Talking to us on [Twitter][3] or [IRC][4].
- Improving the [documentation][5].
- Cloning the [repo][2] and filing bug reports and pull requests on github.
  See [CONTRIBUTING][15] for more details.


Try It
------

You can try LibreNMS by downloading a VM image.  Currently, a Ubuntu-based
image is supplied and has been tested with [VirtualBox][8].

Download the [VirtualBox / VMWare image][11] and open it then log in with credentials provided. 
Enter the following commands:

    cd /opt/librenms
    git pull
    php discover.php -h all
    php poller.php -h all

You'll then need to find out the IP of your VM (`ifconfig | grep add`) and
create a DNS entry for `librenms.example.com` to point to that IP.  You can
also edit your `/etc/hosts` file with the following line:

    $ip librenms.example.com

where `$ip` is the IP of your VM.

Add a new user by entering:

    ./adduser.php <username> <password> 10 <email>

replace <username>, <password> and <email> with a username, password and your email address.

From there, just point your web browser
to `http://librenms.example.com/` and login with your new username and password.
