DK NodesNODE FROM NESA | FULL MANUAL!
Hello fellows! We’ve prepared an all-in-one guide for you that will allow you to set up a NESA node in the easiest way possible! Hello fam! 1. First of all, purchase a server from AEZA, Contabo or Spacecore. Server specifications: • 6 vCPU Cores • 16 GB RAM • 400 GB SSD 2. Set up the server on your PC. Log in using the command root@ip. But before that, we recommend securing your server. Read more in our article.PreparationCreating a Token1. Go to Hugging Face and sign up.2. Create a token by ...
DK NodesThe Importance of Using Different Ports When Running Multiple Nodes on One Server
In today’s world of blockchain networks and dApps, a lot of people run multiple nodes on one server. But there’s one important thing to keep in mind with this setup — each node needs its own port. It might seem like a small detail, but properly setting up ports is crucial for keeping things stable, secure, and scalable. Let’s break down why using different ports for each node matters and how it affects your server’s performance.Ports and Their Role in Network InfrastructureA port is a communi...

In today’s digital world, securing your server is a must, especially if you’re running nodes for blockchain networks or other distributed systems. In this guide, we’ll break down why server security is so important and how to keep things safe on Ubuntu (Linux), including how to generate SSH keys for secure access.
Servers hold a lot of sensitive stuff — like user info, financial data, and company documents. A data leak could lead to major financial hits and mess up your reputation.
Without proper security measures, servers can be targeted by various types of attacks such as DDoS attacks, malware injection, and hacking attempts. These attacks can lead to data loss or service interruption.
A multitude of industries require compliance with data security standards. Failure to comply with these requirements can have legal and financial consequences.
Even in the absence of external attacks, misconfigurations or employee actions can pose a threat to server security. Effective security measures help minimize such risks.

Updates to the operating system and installed packages are critical to protect against vulnerabilities. Use the following commands to update:
sudo apt update sudo apt upgrade
Install and configure ufw (Uncomplicated Firewall) to control access to the server:
sudo apt install ufw sudo ufw allow ssh sudo ufw enable sudo ufw status
Change the default SSH port (22) to another less obvious port. This can be done in the configuration file /etc/ssh/sshd_config.
Disable password authentication and use SSH keys for better security
PasswordAuthentication no
After making configuration changes, restart the SSH service
Run this command to generate SSH keys:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
Follow the steps to save the keys in the right spot. Usually it’s~/.ssh/id_rsa (private key) и ~/.ssh/id_rsa.pub (public key)
To add the public key to your server, use:
ssh-copy-id user@server_ip
Create users with only the permissions they really need, and avoid using the root account for everyday tasks. Use sudo to run commands with higher privileges.
Check and adjust the /etc/sudoers and /etc/sudoers.d/ files to control access.
Install antivirus software like ClamAV and run regular system scans.
sudo apt install clamav
sudo freshclam
sudo clamscan -r /home
Turn on system logging and use tools like fail2ban to automatically block IPs trying to break in.
Set up monitoring tools like Prometheus and Grafana to keep an eye on your server’s performance.
Regularly back up your configuration files and data. Use tools like rsync or dedicated backup solutions to ensure everything is safely stored.
Securing your server is a crucial task that requires a comprehensive approach. Regular system updates, firewall configuration, secure SSH setup, and user management are key to keeping your server protected. If you’re running nodes for blockchain networks, be mindful of resource requirements and apply the same security measures to ensure stable performance and data protection.
