# innernet
.
A private network system that uses [WireGuard](https://wireguard.com) under the
hood. See the [announcement blog
post](https://blog.tonari.no/introducing-innernet) for a longer-winded
explanation.

`innernet` is similar in its goals to Slack's
[nebula](https://github.com/slackhq/nebula) or
[Tailscale](https://tailscale.com/), but takes a bit of a different approach.
It aims to take advantage of existing networking concepts like CIDRs and the
security properties of WireGuard to turn your computer's basic IP networking
into more powerful ACL primitives.
.
`innernet` is not an official WireGuard project, and WireGuard is a registered
trademark of Jason A. Donenfeld.
.
This has not received an independent security audit, and should be considered
experimental software at this early point in its lifetime.
.
## Usage
.
### Server Creation
.
Every `innernet` network needs a coordination server to manage peers and
provide endpoint information so peers can directly connect to each other.
Create a new one with
.
```sh
sudo innernet-server new
```
.
The init wizard will ask you questions about your network and give you some
reasonable defaults. It's good to familiarize yourself with [network
CIDRs](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) as a lot
of innernet's access control is based upon them. As an example, let's say the
root CIDR for this network is `10.60.0.0/16`. Server initialization creates a
special "infra" CIDR which contains the `innernet` server itself and is
reachable from all CIDRs on the network.
.
Next we'll also create a `humans` CIDR where we can start adding some peers.
.
```sh
sudo innernet-server add-cidr <interface>
```
.
For the parent CIDR, you can simply choose your network's root CIDR. The name
will be `humans`, and the CIDR will be `10.60.64.0/24` (not a great example
unless you only want to support 256 humans, but it works for now...).
.
By default, peers which exist in this new CIDR will only be able to contact
peers in the same CIDR, and the special "infra" CIDR which was created when the
server was initialized.
.
A typical workflow for creating a new network is to create an admin peer from
the `innernet-server` CLI, and then continue using that admin peer via the
`innernet` client CLI to add any further peers or network CIDRs.
.
```sh
sudo innernet-server add-peer <interface>
```
.
Select the `humans` CIDR, and the CLI will automatically suggest the next
available IP address. Any name is fine, just answer "yes" when asked if you
would like to make the peer an admin. The process of adding a peer results in
an invitation file. This file contains just enough information for the new peer
to contact the `innernet` server and redeem its invitation. It should be
transferred securely to the new peer, and it can only be used once to
initialize the peer.
.
You can run the server with `innernet-server serve <interface>`, or if you're
on Linux and want to run it via `systemctl`, run `systemctl enable --now
innernet-server@<interface>`. If you're on a home network, don't forget to
configure port forwarding to the `Listen Port` you specified when creating the
`innernet` server.
.
### Peer Initialization
.
Let's assume the invitation file generated in the steps above have been
transferred to the machine a network admin will be using.
.
You can initialize the client with
.
```sh
sudo innernet install /path/to/invitation.toml
```
.
You can customize the network name if you want to, or leave it at the default.
`innernet` will then connect to the `innernet` server via WireGuard, generate a
new key pair, and register that pair with the server. The private key in the
invitation file can no longer be used.
.
If everything was successful, the new peer is on the network. You can run
things like
.
```sh
sudo innernet list
```
.
or
.
```sh
sudo innernet list --tree
```
.
to view the current network and all CIDRs visible to this peer.
.
Since we created an admin peer, we can also add new peers and CIDRs from this
peer via `innernet` instead of having to always run commands on the server.
.
### Adding Associations between CIDRs
.
In order for peers from one CIDR to be able to contact peers in another CIDR,
those two CIDRs must be "associated" with each other.
.
With the admin peer we created above, let's add a new CIDR for some theoretical
CI servers we have.
.
```sh
sudo innernet add-cidr <interface>
```
.
The name is `ci-servers` and the CIDR is `10.60.64.0/24`, but for this example
it can be anything.
.
For now, we want peers in the `humans` CIDR to be able to access peers in the
`ci-servers` CIDR.
.
```sh
sudo innernet add-association <interface>
```
.
The CLI will ask you to select the two CIDRs you want to associate. That's all
it takes to allow peers in two different CIDRs to communicate!
.
You can verify the association with
.
```sh
sudo innernet list-associations <interface>
```
.
and associations can be deleted with
.
```sh
sudo innernet delete-associations <interface>
```
.
### Enabling/Disabling Peers
.
For security reasons, IP addresses cannot be re-used by new peers, and
therefore peers cannot be deleted. However, they can be disabled. Disabled
peers will not show up in the list of peers when fetching the config for an
interface.
.
Disable a peer with
.
```su
sudo innernet disable-peer <interface>
```
.
Or re-enable a peer with
.
```su
sudo innernet enable-peer <interface>
```
.
### Specifying a Manual Endpoint
.
The `innernet` server will try to use the internet endpoint it sees from a peer
so other peers can connect to that peer as well. This doesn't always work and
you may want to set an endpoint explicitly. To set an endpoint, use
.
```sh
sudo innernet override-endpoint <interface>
```
.
You can go back to automatic endpoint discovery with
.
```sh
sudo innernet override-endpoint -u <interface>
```
.
### Setting the Local WireGuard Listen Port
.
If you want to change the port which WireGuard listens on, use
.
```sh
sudo innernet set-listen-port <interface>
```
.
or unset the port and use a randomized port with
.
```sh
sudo innernet set-listen-port -u <interface>
```
.
### Remove Network
.
To permanently uninstall a created network, use
.
```sh
sudo innernet-server uninstall <interface>
```
.
Use with care!
.
## Security recommendations
.
If you're running a service on innernet, there are some important security
considerations.
.
### Enable strict Reverse Path Filtering ([RFC
3704](https://tools.ietf.org/html/rfc3704))
.
Strict RPF prevents packets from _other_ interfaces from having internal source
IP addresses. This is _not_ the default on Linux, even though it is the right
choice for 99.99% of situations. You can enable it by adding the following to a
`/etc/sysctl.d/60-network-security.conf`:
.
```
net.ipv4.conf.all.rp_filter=1
net.ipv4.conf.default.rp_filter=1
```
.
### Bind to the WireGuard device
.
If possible, to _ensure_ that packets are only ever transmitted over the
WireGuard interface, it's recommended that you use `SO_BINDTODEVICE` on Linux
or `IP_BOUND_IF` on macOS/BSDs. If you have strict reverse path filtering,
though, this is less of a concern.
.
### IP addresses alone often aren't enough authentication
.
Even following all the above precautions, rogue applications on a peer's
machines could be able to make requests on their behalf unless you add extra
layers of authentication to mitigate this CSRF-type vector.
.
It's recommended that you carefully consider this possibility before deciding
that the source IP is sufficient for your authentication needs on a service.
.
## Installation
.
innernet has only officially been tested on Linux and MacOS, but we hope to
support as many platforms as is feasible!
.
### Runtime Dependencies
.
It's assumed that WireGuard is installed on your system, either via the kernel
module in Linux 5.6 and later, or via the
[`wireguard-go`](https://git.zx2c4.com/wireguard-go/about/) userspace
implementation.
.
