If you’ve purchased a Linux VPS, you can connect to it securely using SSH (Secure Shell). In this guide, we’ll show you how to log in to your Linux VPS using PuTTY from a Windows computer.

What You Need Before Connecting

Make sure you have the following details from your VPS welcome email:

  • Server IP Address
  • Username (usually root)
  • Password or SSH Private Key
  • Port Number (default SSH port is 22)

Step 1: Download PuTTY

  1. Go to the official PuTTY website https://putty.org/
  2. Download the latest Windows installer
  3. Install PuTTY on your computer

Step 2: Open PuTTY

After installation:

  1. Open PuTTY
  2. You will see the “PuTTY Configuration” window

Step 3: Enter Your VPS Details

  • Host Name (or IP address): Enter your VPS IP
  • Port: 22 (unless your provider gave you a custom port)
  • Connection type: Select SSH

Then click Open.

Step 4: Accept Security Alert

The first time you connect, PuTTY will show a security warning.

  • Click Accept

This is normal for first-time connections.

Step 5: Login to Your Server

A black terminal window will open.

  1. Type your username (example: root)
  2. Press Enter
  3. Enter your password
  4. Press Enter

Note: When typing your password, nothing will appear on the screen. This is normal for security reasons.

If successful, you will see something like:

root@yourserver:~#

🎉 You are now logged into your Linux VPS.

How to Login Using an SSH Key (More Secure Method)

If your VPS uses SSH key authentication:

Step 1:

  • In PuTTY, go to Connection → SSH → Auth
  • Click Browse
  • Select your .ppk private key file

Step 2:

  • Go back to Session
  • Enter your VPS IP
  • Click Open

Common SSH Issues & Fixes

Connection Timed Out?

  • Check your IP address is correct
  • Ensure your VPS is powered on
  • Verify port 22 is open in your firewall

Access Denied?

  • Double-check username
  • Re-enter password carefully
  • Ensure you’re using the correct SSH key

Network Error: Connection Refused?

  • SSH service may not be running
  • Firewall may be blocking port 22

Security Tips for Linux VPS

  • Disable root login (recommended)
  • Create a new sudo user
  • Change the default SSH port
  • Use SSH keys instead of passwords
  • Install a firewall like UFW or CSF
