I will set up and secure your ubuntu or debian vps server
Blockchain Developer, Block Explorers and Node Infrastructure
About this Gig
I set up Ubuntu and Debian servers so they are safe to put online: no root login, no password brute force, only the ports you actually need.
WHAT I DO
Create a sudo user with SSH key login, then disable root and password login.
Configure the UFW firewall to allow only the ports your apps need.
Run a full system update and set hostname, timezone and swap.
Standard adds fail2ban, Nginx reverse proxy and free Let's Encrypt SSL for your domain.
Premium adds Docker, unattended security upgrades, a daily backup cron job and basic monitoring.
HOW IT WORKS
You send me the server IP and temporary access. I do the work and send back a short report: what changed, your new login command and where the config files are. Everything is documented so you can repeat it yourself later.
I run my own servers and blockchain nodes every day, so this is the same checklist I use on my own machines.
Just bought a VPS and not sure what to do first? Message me and I will tell you what your server needs before you order.

FAQ
Do you need my root password?
No. Add my public SSH key or give temporary access that you revoke after delivery. I never ask for wallet keys, payment details or personal accounts.
Which providers and systems do you work with?
Any provider: Hetzner, Contabo, DigitalOcean, Vultr, OVH, Linode, AWS Lightsail and others. Ubuntu 20.04 to 24.04 and Debian 11 or 12.
Will my website or app go down?
No. I only change SSH, firewall and system settings, your running services stay up. If a reboot is needed I ask you first and we pick a time.
