How to Setup and Secure Your Server

This article will guide you through the preparation of your server for ONZ Coin Node.

To complete this tutorial, you will need:

• One Ubuntu 16.04 server, with a minimum of 1 CPU core and 2GB ram.
• Ideally a KVM based VPS

First of all you’ll need to login into your server using root:

Login as: root

Password: YOUR_VPS_PROVIDERS_ROOT_PASSWORD

Now, you need to complete the following commands:

apt-get update && apt-get upgrade && apt-get dist-upgrade

apt-get install ntp

service ntp stop

apt install ntpdate

service ntp start

apt-get install nano git ufw tar

If you don’t plan to use the Secure Node Guide after this one, you will also need to open the correct ports for testnet or mainnet.

Testnet Ports

ufw allow 22/tcp

ufw allow 10998/tcp

ufw allow 10999/tcp

ufw enable

Mainnet Ports

ufw allow 22/tcp

ufw allow 11000/tcp

ufw allow 11001/tcp

ufw enable

The next step, make a user:

adduser yourusername (create new secure password)

usermod -a -G sudo yourusername

sudo visudo

Add this line at the end below “#includedir /etc/sudoers.d”:

yourusername ALL=(ALL) NOPASSWD:ALL

After editing the file press Ctrl+x and confirm with y and then Enter.Your server is now ready, reboot the server with:

reboot

Wait for few minutes for the server to restart, login using the new user and password you created above.

ssh yourusername@111.222.333.444

Please proceed to the Secure Node Installation guide, if you don’t wish to secure the node, then please continue to either the TESTNET or MAINNET guides by clicking on the links.
