How to connect to your VPS via SSH

A VPS gives you root access, which means there is no control panel between you and the machine unless you install one. SSH is how you reach it. PowrNode plans start at €19 a month with full root access, so everything below applies from the entry tier upward.

If you have never used a terminal, this is a reasonable place to start — the first connection is four commands and the rest is ordinary Linux administration.

Before you start

• Find your VPS IP address and root password in the client portal under your service details.
• On Windows 10 or later, SSH is built into Windows Terminal and PowerShell; you no longer need PuTTY unless you prefer it.
• On macOS and Linux, use the built-in Terminal.

Steps

1. Open your terminal.
2. Run: ssh root@YOUR_VPS_IP
3. The first connection shows a host key fingerprint. Accept it by typing yes — this pins the server's identity so a future mismatch warns you.
4. Enter the root password from the client portal. Nothing appears on screen as you type; that is deliberate.
5. Change the password immediately with: passwd
6. Update the system before installing anything: apt update && apt upgrade on Debian or Ubuntu, dnf update on AlmaLinux or Rocky.

Check that it worked

• Run whoami — it should return root.
• Run hostnamectl to confirm you are on the machine you expected.
• Run df -h to see the disk, which is a quick sanity check that the storage matches the plan you bought.

If it goes wrong

Connection times out

A timeout means nothing answered, which is usually a firewall rather than a wrong password. Check the IP, and check whether your own network blocks outbound port 22 — corporate and hotel networks frequently do. Trying from a phone hotspot isolates that quickly.

Permission denied after entering the password

Copy the password from the portal rather than typing it, since a trailing space or a confused character is the usual cause. If you have already disabled root password login while hardening the server, connect with your key or your sudo user instead.

Warning about a changed host key

This appears legitimately after a rebuild or reinstall, and illegitimately if traffic is being intercepted. If you did not rebuild the server, stop and contact us before connecting. If you did, remove the old entry with: ssh-keygen -R YOUR_VPS_IP

Before putting anything real on the server, set up key-based authentication and disable password login. Password authentication on port 22 attracts automated attempts within minutes of a server appearing online, and a key removes that entire category of risk.

VPS plans from €34 a month include snapshots, which are worth taking before any change you are not certain about. Rolling back a snapshot takes seconds; rebuilding a broken server takes an evening.
