1- Where to buy VPS

The first thing that is needed to participate in Node Testnets is a VPS server

In order to buy a VPS ( Cloud Server), I introduce several good (in my opinion) foreign & Iranian providers with and without crypto payment with brief information

Rank Provider Payment Method Discription
1 Hetznr Credit card - need KYC Best Hosting , not very cheap auction servers (min. $30) are good
2 Contabo Credit card - need KYC Cheap but for a very few nodes we had bandwidth issues
3 Hostbrr Crypto Cheap to Normal pricing, good performance
4 PQhosting Crypto Good performance and some cheap servers
5 Aeza Crypto Best for hourly servers, they have good servers sometimes
6 Bartarvs Rial - Crypto Iranian - Myloc & Contabo cloud servers are cheap but myloc is low performance

I'm not RESPONSIBLE nor AFFILATED with any of these providers. I just used them before, and I think they are good choice. You can choose wherever you think is better

2- What system to buy

Before buying a VPS, we must consider several components to choose the required system

  • CPU: Usually, 4core to 16core
  • Ram: Usually, 4GB to 32GB
  • HDD, SSD: Projects always consider the hard disk of the Nodes to be higher than required. In few nodes such as Prover or Validator in Active-set maybe a lot of hard disk is needed. Minimum is better to be 60
  • Operating-system must be Ubuntu, Ubuntu 22 is usually compatible with every project
  • VPS must be ipv4 and must NOT be NAT

3- Let's Buy a VPS

To understand better, let's buy a server from 2 Iranian and foreign providers

This is not an advice to buy from them and I just want to show you the process

After this guide, I'm not sure if they will get out of stock of their servers, you can consider creating a ticket to ask before proceeding to buy

Hostbrr

Let's list some of their servers orders:

High RAM: Memory-Optimized VPS

High RAM - Better net bandwidth: RAM-Optimized - Premium

Good CPU: AMD Ryzen 9 7950XD

Good CPU - Cheaper: AMD Ryzen 9 5950X

High SSD - Out of stock right now: Big Storage Servers

1- I pick $14.99 VPS from AMD Ryzen 9 5950X

  • 4 vCore ,8GB RAM, 150 GB Storage can be a good choice for me

2- I register my Contact Information and pay with my metamask wallet through Coinbase Commence payment method

3- Install Ubuntu.22

  • After payment, I wait until my server to get active in services page
  • We must install ubuntu manually in Hostbrr when server is activated

List of Cloud Servers

Cheap - Normal performance: MyLoc

Cheapest - Good performance - I remember only 1 node had bandwidth issue: Contabo

Config Before buy

in Iranian providers, you must choose configs before the payment, you usually don't have access to control panel and they will do the things for you with a ticket

Remember to choose Ubuntu 22 & SSD (Higher storage) Screenshot_4

4- How to connect to VPS

1- You need a client to connect to your VPS through SSH

List of Clients:

1- My prefer: Mobaxterm (has SFTP: you can manage your files & directories

2- Termius (has SFTP)

3- Putty (No SFTP, Just a terminal)

2- VPS Details

You need following details to connect to your VPS through SSH

  • IP: Provider will email you after activation
  • Port: Default open port for SSH connection is always 22
  • User: Default user is always root
  • Password: Provider will email you after activation

3- Connect via Mobaxterm

1- Click session and open SSH tab

2- In Remote host you must fill your server IP, if you write root@ behind it, it uses root as user

3- Default SSH port is 22

4- After clicking OK, a Terminal opens which needs your password, Copy it & Paste it in the reminal by clicking Mouse Middle Scroll Wheel, Password will be hidden in terminal

4- Now you have a Terminal that you can write your commands in it
