Introduction

This guide is intended for someone who is looking to setup a zencash Super Node. A Super Node is intended to be installed on a Virtual Private Server (VPS), Virtual Machine (VM), or standalone server hardware with a 64-bit architecture. Setup will be performed from a command line interface or CLI. On Windows 7 64-bit and newer, this will most commonly be PuTTY, and Terminal on Mac OS and Linux.

The format of the guide is deliberately column-based providing a description on the left, alongside each of the steps, to clarify the exact purpose. A more experienced user may prefer to simply follow the commands in the right column. The guide supports a simple double-click copy and paste of each command into a terminal.

Where applicable, these images will be displayed to indicate if a particular step or page in the guide is specific to one or more operating system. If none are present, the steps apply universally.

Mac OS Linux Windows

For the best experience with the guide, maximize your window screen such that you do not have any horizontal scroll bar

DO NOT INSTALL AND RUN A SUPER NODE UNDER THE ROOT USER. The guide details how to add a non-root user, under which the necessary processes will run.

NOTE: Previous installation guides advised to use a 1 GB VPS server with 4 GB of swap on an SSD. Extensive testing and community feedback revealed that these specifications are no longer suitable.

The recommended total memory allocation is 6GB (RAM + SWAP). CPUs of an Intel Haswell architecture (or AMD equivalent) and newer have been performing well.

Nodes configured with 4GB of RAM and 2GB of SWAP have shown to reliably pass challenges
Nodes configured with 2GB of RAM and 4GB of SWAP have had some luck with passing challenges
Nodes configured with 1GB of RAM and 5GB of SWAP have seldom passed challenges

Description

Command

1

Domain Name Registration & Propagation

A domain name registration (DNS record) is required for a Super Node. This must point to the external IP address of the Super Node. The value used for your DNS record is referred to as your Fully-Qualified Domain Name (FQDN). It will have a format along the lines of >> myhost.mydomain.com

Before you begin configuration of your Super Node, verify your domain name has fully propagated. You can check this at "what is my dns?". If you're using an ipv4 public address, you have an "A" record, if you're using an ipv6 address, you have an "AAAA" record. Enter your FQDN into the search engine with your appropriate DNS record and search. If your FQDN has fully propagated, all the servers in the listing will have a green check mark.

2

Verify that you can reach your node (using the domain name) from your local machine. Replace the example (myhost.mydomain.com) in the command with your own FQDN.

Mac OS - use Terminal (press <CMD> + <SPACE> and type terminal, followed by <Enter>)
Linux - open the Terminal application (exact steps differ per distribution)

ping -c 3 myhost.mydomain.com

Terminal

satoshi@goldwasser:~$ ping -c 3 node01.zentest.win
