Auto Interface
==============
The Auto Interface enables communication with other discoverable Reticulum
nodes over UDP. It does not need any functional IP infrastructure like
routers or DHCP servers, but will require at least some sort of switching
medium between peers (a wired switch, a WiFi access point or similar), and
that link-local IPv6 is enabled in your operating system, which should be
enabled by default in almost all OSes.
.. code::
# This example demonstrates a TCP server interface.
# It will listen for incoming connections on the
# specified IP address and port number.
[[Default Interface]]
type = AutoInterface
interface_enabled = True
outgoing = True
# You can create multiple isolated Reticulum
# networks on the same physical LAN by
# specifying different Group IDs.
group_id = reticulum
If you are connected to the Internet with IPv6, and your provider will route
IPv6 multicast, you can potentially configure the Auto Interface to globally
autodiscover other Reticulum nodes within your selected Group ID. You can specify
the discovery scope by setting it to one of ``link``, ``admin``, ``site``,
``organisation`` or ``global``.
.. code::
[[Default Interface]]
type = AutoInterface
interface_enabled = True
outgoing = True
# Configure global discovery
group_id = custom_network_name
discovery_scope = global
# Other configuration options

What is Reticulum?
******************
Reticulum is a cryptography-based networking stack for wide-area networks built on readily available hardware, and can operate even with very high latency and extremely low bandwidth.
Reticulum is a cryptography-based networking stack for wide-area networks built on readily available hardware, that can operate even with very high latency and extremely low bandwidth.
Reticulum allows you to build very wide-area networks with off-the-shelf tools, and offers end-to-end encryption, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable packet acknowledgements and more.

<p>Reticulum is a complete networking stack, and does not need IP or higher layers, although it is easy to utilise IP (with TCP or UDP) as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks. Reticulum is built directly on cryptographic principles, allowing resilience and stable functionality in open and trustless networks.</p>
<p>No kernel modules or drivers are required. Reticulum runs completely in userland, and can run on practically any system that runs Python 3. Reticulum runs well even on small single-board computers like the Pi Zero.</p>
