-# Telebit&trade; Relay
+# Telebit Relay

-A server that works in combination with [stunnel.js](https://git.coolaj86.com/coolaj86/tunnel-client.js)
+Friends don't let friends localhost&trade;
+
+A server that works in combination with [Telebit Remote](https://git.coolaj86.com/coolaj86/telebit.js)
 to allow you to serve http and https from any computer, anywhere through a secure tunnel.

-| Sponsored by [ppl](https://ppl.family) | **Telebit Relay** | [Telebit](https://git.coolaj86.com/coolaj86/tunnel-client.js) |
+| Sponsored by [ppl](https://ppl.family) | **Telebit Relay** | [Telebit Remote](https://git.coolaj86.com/coolaj86/telebit.js) |

-CLI
-===
+Features
+========

-Installs as `stunnel.js` with the alias `jstunnel`
-(for those that regularly use `stunnel` but still like commandline completion).
+* [x] Expose your bits even in the harshest of network environments
+  * [x] NAT, Home Routers
+  * [x] College Dorms, HOAs
+  * [x] Corporate Firewalls, Public libraries, Airports
+  * [x] and even Airplanes, yep
+* [x] Automated HTTPS (Free SSL)

-### Install
+Install
+=======
+
+Mac & Linux
+-----------
+
+Open Terminal and run this install script:

 ```bash
-npm install -g stunneld
+curl -fsSL https://get.telebit.cloud/relay | bash
 ```

-Then `dist/etc/systemd/system/stunneld.service` should be copied to `/etc/systemd/system/stunneld.service` and
-the ARGUMENTS, such as SECRET, MUST BE CHANGED.
+Of course, feel free to inspect the install script before you run it.

-*TODO*: make `--config /path/to/config` the only argument (and have the secret auto-generated on first run?)
+This will install Telebit Relay to `/opt/telebit-relay` and
+put a symlink to `/opt/telebit-relay/bin/telebit-relay` in `/usr/local/bin/telebit-relay`
+for convenience.

-## Note: Use node.js v8.x
-
-There is a bug in node v9.x that causes stunneld to crash.
-
-https://github.com/nodejs/node/issues/20241
-
-### Advanced Usage
-
-How to use `stunnel.js` with your own instance of `stunneld.js`:
+You can customize the installation:

 ```bash
-stunneld.js --servernames tunnel.example.com --protocols wss --secret abc123
+export NODEJS_VER=v10.2
+export TELEBIT_RELAY_PATH=/opt/telebit-relay
+curl -fsSL https://get.telebit.cloud/relay
+```
+
+That will change the bundled version of node.js is bundled with Telebit Relay
+and the path to which Telebit Relay installs.
+
+You can get rid of the tos + email and server domain name prompts by providing them right away:
+
+```bash
+curl -fsSL https://get.telebit.cloud/relay | bash -- jon@example.com telebit-relay.example.com
+```
+
+Windows & Node.js
+-----------------
+
+1. Install [node.js](https://nodejs.org)
+2. Open _Node.js_
+2. Run the command `npm install -g telebit-relay`
+
+**Note**: Use node.js v8.x or v10.x
+
+There is [a bug](https://github.com/nodejs/node/issues/20241) in node v9.x that causes telebit-relay to crash.
+
+Usage
+====
+
+```bash
+telebit-relay --config /opt/telebit-relay/etc/telebit-relay.yml
 ```

 Options

+`/opt/telebit-relay/etc/telebit-relay.yml:`
 ```
--secret          the same secret used by stunnel client (used for authentication)
--serve           comma separated list of <proto>:<servername>:<port> to which
-                  incoming http and https should be forwarded
+email: 'jon@example.com'       # must be valid (for certificate recovery and security alerts)
+agree_tos: true                # agree to the Telebit, Greenlock, and Let's Encrypt TOSes
+community_member: true         # receive infrequent relevant but non-critical updates
+telemetry: true                # contribute to project telemetric data
+secret: ''                     # JWT authorization secret. Generate like so:
+                               # node -e "console.log(crypto.randomBytes(16).toString('hex'))"
+servernames:                   # hostnames that direct to the Telebit Relay admin console
+  - telebit-relay.example.com
+  - telebit-relay.example.net
+vhost: /srv/www/:hostname      # securely serve local sites from this path (or false)
+                               # (uses template string, i.e. /var/www/:hostname/public)
+greenlock:
+  store: le-store-certbot      # certificate storage plugin
+  config_dir: /opt/telebit-relay/etc/acme    # directory for ssl certificates
 ```

-### Privileged Ports without sudo
-
-```bash
-# Linux
-sudo setcap 'cap_net_bind_service=+ep' $(which node)
-```
-
-### Alterntive Methods
-
-**NOT YET IMPLEMENTED**
-
-We created this for anyone to use on their own server or VPS,
-but those generally cost $5 - $20 / month and so it's probably
-cheaper to purchase data transfer (which we supply, obviously),
-which is only $1/month for most people.
-
-Just use the client ([stunnel.js](https://git.coolaj86.com/coolaj86/tunnel-client.js))
-with this tunneling service (the default) and save yourself the monthly fee
-by only paying for the data you need.
-
-	* Node WS Tunnel (zero setup)
-	* Heroku (zero cost)
-	* Chunk Host (best deal per TB/month)
-
 Security
 ========

 The bottom line: As with everything in life, there is no such thing as anonymity
-or absolute security. Only use stunneld services that you trust. :D
+or absolute security. Only use Telebit Relays that you trust or self-host. :D

-Even though the traffic is encrypted end-to-end, you can't just trust any stunneld service
+Even though the traffic is encrypted end-to-end, you can't just trust any Telebit Relay
 willy-nilly.

-A man-in-the-middle attack is possible using Let's Encrypt since an evil stunneld service
-would be able to complete the http-01 and tls-sni-01 challenges without a problem
+A man-in-the-middle attack is possible using Let's Encrypt since an evil Telebit Relay
+would be able to complete the http-01 challenges without a problem
 (since that's where your DNS is pointed when you use the service).

 Also, the traffic could still be copied and stored for decryption is some era when quantum
 computers exist (probably never).
+
+Why?
+====
+
+We created this for anyone to use on their own server or VPS,
+but those generally cost $5 - $20 / month and so it's probably
+cheaper to purchase data transfer, which is only $1/month for
+most people.
+
+In keeping with our no lock-in policy, we release a version of
+the server for anyone to use independently.
+
+TODO show how to do on
+
+	* Node WS Tunnel (zero setup)
+	* Heroku (zero cost)
+	* Chunk Host (best deal per TB/month)
+
+Useful Tidbits
+===
+
+## As a systemd service
+
+`./dist/etc/systemd/system/telebit-relay.service` should be copied to `/etc/systemd/system/telebit-relay.service`.
+
+The user and group `telebit` should be created.
+
+## Use privileged ports without sudo
+
+```bash
+# Linux
+sudo setcap 'cap_net_bind_service=+ep' $(which node)
+```
