  • We recommend connecting to a VM over SSH using a public-private key pair, also known as SSH keys.

You can generate a new SSH key on your local machine. After you generate the key, you can add the public key to your vm on enable authentication over SSH.

ssh-keygen -t rsa

Enter a file location to save the key to (by default it will save to your users directory)

When you are prompted to type a passphrase, press Enter Once you've successfully created your private key will be saved in <your_chosen_directory>.ssh/id_rsa and your public key will be saved in <your_chosen_directory>.ssh/id_rsa.pub.

  • Now go to your local computer terminal
ssh -i <your_chosen_directory>.ssh/id_rsa ubuntu@<ip_address_of_node>

You should now be connected to your instance

note: Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported.
