How to Connect to Azure VM: Simple Steps for Beginners

To connect to an Azure VM, use Remote Desktop Protocol (RDP) for Windows VMs or SSH for Linux VMs. You need the VM's public IP address, username, and authentication method like a password or SSH key.

📐

Syntax

Connecting to an Azure VM depends on its operating system:

Windows VM: Use mstsc /v:<public-ip> in Command Prompt or Remote Desktop app.
Linux VM: Use ssh <username>@<public-ip> in a terminal.

Replace <public-ip> with your VM's public IP address and <username> with your VM's user name.

bash

mstsc /v:<public-ip>  # For Windows VM

ssh <username>@<public-ip>  # For Linux VM

💻

Example

This example shows how to connect to a Linux Azure VM using SSH with a username azureuser and public IP 52.170.12.34.

bash

ssh azureuser@52.170.12.34

Output

The authenticity of host '52.170.12.34 (52.170.12.34)' can't be established. ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '52.170.12.34' (ECDSA) to the list of known hosts. azureuser@52.170.12.34's password:

⚠️

Common Pitfalls

Missing Public IP: Ensure your VM has a public IP address assigned.
Network Security Group (NSG) Rules: Check that inbound rules allow RDP (port 3389) for Windows or SSH (port 22) for Linux.
Wrong Credentials: Use the correct username and password or SSH key.
Firewall Blocking: Local or corporate firewalls might block the connection ports.

bash

Wrong way:
ssh azureuser@52.170.12.34 -p 3389  # Using RDP port for SSH will fail

Right way:
ssh azureuser@52.170.12.34  # Default SSH port 22

Quick Reference

Step	Action	Details
1	Find VM Public IP	Go to Azure Portal > Virtual Machines > Your VM > Overview > Public IP address
2	Check NSG Rules	Ensure inbound port 3389 (Windows) or 22 (Linux) is allowed
3	Connect to VM	Use `mstsc /v:<IP>` for Windows or `ssh user@<IP>` for Linux
4	Authenticate	Enter your VM username and password or SSH key
5	Troubleshoot	Verify firewall and network settings if connection fails

✅

Key Takeaways

Use RDP for Windows VMs and SSH for Linux VMs to connect.

Always verify your VM's public IP and network security rules before connecting.

Use correct username and authentication method (password or SSH key).

Check local and cloud firewalls if connection issues occur.
