Install Telebit Remote on any device - your laptop, raspberry pi, whatever - and now you can access that device from anywhere, even securely in a web browser.

How does it work? It's a net server that uses a relay to allow multiplexed incoming connections on any external port.

Features

Show your mom the web app you're working on
Access your Raspberry Pi from behind a firewall
Watch Netflix without region restrictions while traveling
SSH over HTTPS on networks with restricted ports or protocols
Access your wife's laptop while she's on a flight

Examples

As a user service

telebitd --config ~/.config/telebit/telebitd.yml &

As a system service

sudo telebitd --config ~/.config/telebit/telebitd.yml

Example output:

Connect to your device by any of the following means:

SSH+HTTPS
        ssh+https://lucky-duck-37.telebit.cloud:443
        ex: ssh -o ProxyCommand='openssl s_client -connect %h:%p -servername %h -quiet' lucky-duck-37.telebit.cloud -p 443

SSH
        ssh://ssh.telebit.cloud:32852
        ex: ssh ssh.telebit.cloud -p 32852

TCP
        tcp://tcp.telebit.cloud:32852
        ex: netcat tcp.telebit.cloud 32852

HTTPS
        https://lucky-duck-37.telebit.cloud
        ex: curl https://lucky-duck-37.telebit.cloud

# Forward all https traffic to port 3000
telebit http 3000

# Forward all tcp traffic to port 5050
telebit tcp 5050

# List all rules
telebit list

Install

Mac & Linux

Open Terminal and run this install script:

curl -fsSL https://get.telebit.cloud | bash

What does the installer do?

install Telebit Remote to /opt/telebit
symlink the executables to /usr/local/bin for convenience
- /usr/local/bin/telebitd => /opt/telebit/bin/telebitd
- /usr/local/bin/telebit => /opt/telebit/bin/telebit
create the appropriate system launcher file
- /etc/systemd/system/telebit.service
- /Library/LaunchDaemons/cloud.telebit.remote.plist
create local user config
- ~/.config/telebit/telebit.yml
- ~/.local/share/telebit

Of course, feel free to inspect it before you run it: curl -fsSL https://get.telebit.cloud

You can customize the installation:

export NODEJS_VER=v10.2
export TELEBIT_PATH=/opt/telebit
export TELEBIT_VERSION=v1              # git tag or branch to install from
curl -fsSL https://get.telebit.cloud/

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:

curl -fsSL https://get.telebit.cloud/ | bash -- jon@example.com example.com telebit.example.com xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Windows & Node.js

Install node.js
Open Node.js
Run the command npm install -g telebit
Copy the example daemon conifg to your user folder .config/telebit/telebitd.yml (such as /Users/John/.config/telebit/telebitd.yml)
Copy the example remote conifg to your user folder .config/telebit/telebit.yml (such as /Users/John/.config/telebit/telebit.yml)
Change the email address
Run npx telebit init and follow the instructions
Run npx telebit list

Note: Use node.js v10.2.1

(there are specific bugs in each of v8.x, v9.x, v10.0, and v10.3 that each cause telebit to crash)

telebit disable                         # allow incoming connections
telebit restart                         # kill daemon and allow system launcher to restart it

telebit list                            # list rules for servernames and ports

Choosing A Relay

You can create a free or paid account at https://telebit.cloud or you can run Telebit Relay open source on a VPS (Vultr, Digital Ocean) or your Raspberry Pi at home (with port-forwarding).

Only connect to Telebit Relays that you trust.
