ngrok-install

A simple self-sufficient script that installs a ngrok ssh tunnel service that runs on boot for the raspberry pi:

Install

You'll need your account's AUTH_TOKEN get it on your ngrok's dashboard:

On your Pi's shell

  1. Copy/Download the install.sh file
  2. Give permission:
sudo chmod 755 install.sh
  1. Run
sudo ./install.sh <AUTH_TOKEN> <REGION>
  • REGION argument is optional (defaults to us)

After the installation is complete you can delete the install.sh file. If you get erros from linux complaining about read-only file system try to run:

sudo mount -o remount,rw /

Uninstall

To stop/remove ngrok from your pi

On your Pi's shell

  1. Copy/Download the uninstall.sh file
  2. Give permission:
sudo chmod 755 uninstall.sh
  1. Run
sudo ./uninstall.sh

Alias

I've written an alias to make it simple to connect to ngrok tunnels.

On your local machine's bash/zshrc add:

alias ngrok='function _f() { ssh -p "$1" [email protected]."${2:-eu}".ngrok.io } ; _f'

Connect using the alias

Open the terminal and run:

ngrok PORT REGION

Since I'm in Europe I've defaulted the alias to eu, depending on your region you can change: "${2:-eu}" to your choice of default region, e.g: "${2:-us}"

Now to ssh into any of my pi's I just run

# 11223 is the PORT number
ngrok 11223

# Same as (depending on your default value)
ngrok 11223 eu

# If I wish to connect to my non-default region, e.g us
ngrok 11223 us
