Telebit™ Remote

Because friends don't let friends localhost™

| Sponsored by ppl | Telebit Remote | Telebit Relay |

Break out of localhost.

If you need to get bits from here to there, Telebit gets the job done.

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

You do this:

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

You get this:

~/telebit http 3000
> Forwarding lucky-duck-42.telebit.cloud => localhost:3000

~/telebit http ~/sites/example.com/
> Serving ~/sites/example.com/ as lucky-duck-42.telebit.cloud

And this:

~/telebit tcp 5050
> Forwarding telebit.cloud:1337 => localhost:5050

And even this:

~/telebit ssh auto
> Forwarding ssh telebit.cloud -p 1337 => localhost:22
> Forwarding ssh+https (openssl proxy) => localhost:22

No privileged ports. No sudo. End-to-end encryption.

Fastest way to test a site, share a file, and pair over ssh.

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 ~/Applications/telebit/
  • symlink the executable to ~/telebit for convenience
  • create the appropriate system launcher file
    • /etc/systemd/system/telebit.service
    • ~/Library/LaunchAgents/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                   # v10.2 is tested working, but we can test other versions
export TELEBIT_VERSION=master             # git tag or branch to install from
export TELEBIT_USERSPACE=no               # install as a system service (launchd, systemd only)
export TELEBIT_PATH=/opt/telebit
export TELEBIT_USER=telebit
export TELEBIT_GROUP=telebit
curl -fsSL https://get.telebit.cloud/ | bash

That will change the bundled version of node.js is bundled with Telebit Relay and the path to which Telebit Relay installs.

Windows & Node.js

  1. Install node.js
  2. Open Node.js
  3. Run the command npm install -g telebit
  4. Copy the example daemon conifg to your user folder .config/telebit/telebitd.yml (such as /Users/John/.config/telebit/telebitd.yml)
  5. Copy the example remote conifg to your user folder .config/telebit/telebit.yml (such as /Users/John/.config/telebit/telebit.yml)
  6. Change the email address
  7. Run npx telebit init and follow the instructions
  8. 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)

Remote Usage

# domain and port control
telebit <service> <handler> [servername] [options ...]

Examples:

telebit status                          # whether enabled or disabled
telebit enable                          # disallow incoming connections
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.
