A Ruby script that runs an Ethereum Validator node through a pre flight checklist.

Requirements

1. Linux - Ubuntu or Debian OS Family

2. Ruby language. In case Ruby is not installed, try one of the 2 options:

• Via rvm, in case you want more flexible control over the Ruby version. Follow the instructios at https://rvm.io/. Then type rvm install 3.0.1

• Directly through the package manager: sudo snap install ruby

3. An ETH1 client, and ETH2 Beacon and Validator clients. Currently this checklist only works with Geth and Prysm. Support for other clients is planned.

Installation

1. Clone this repository.

2. In this repository type bundle install to install Ruby dependencies.

3. Type rake create_config to initialize configuration file for main net or rake create_config_testnet for testnet.

4. The configuration file config.yml contains your local settings, such as names of data directories, user names, ports etc. Edit this file if needed. By default it follows the conventions in Somer Esat's staking guide.

Usage

Perform checks via Rake tasks

• rake -T will show all available tasks.

• rake checklist will go through the entire checklist and report the failed checks. Note: Some of the checks require sudo priviledges so you may need to enter a password if you are not a superuser.

Perform checks manually via Ruby console

• ./console to start the console.

• A checklist object will be loaded.

• This object has various sub-objects that contain diagnostic methods. Examples: checklist.clients.geth.version_check, or checklist.firewall.active?
