Log Into Your Virtual Compute Node

You can access your Virtual Compute Node through SSH keys (if previously added) or the root password sent to you on your account’s email address.

Linux Users​

(i) Password-Based Login – Linux​

  1. Open the terminal (Application → Accessories → Terminal).
  2. Type the following command:


$ ssh username@hostname

Note

where username is the name of the user of the target computer & hostname is the IP address, i.e., the Public IP that you will be connecting to

Terminal Command

  1. The first time you log in, you may see the following message:

info

The authenticity of host ‘#.#.#.#(#.#.#.#)’ can’t be established. RSA key fingerprint is ————–. Are you sure you want to continue connecting (yes/no)?

Type yes to continue.

  • Next Terminal will prompt you for a password.
  • username@hostname password: Type password & press Enter key 4.
  • Login with your credentials (You can access your login credentials from an e-mail sent to you).

You can log in to a remote Linux server without entering a password by your public/private key pair.

  • If you have not generated an SSH Keypair, please visit – How To Set-Up SSH Keys – Linux.

  • To SSH into your Linux virtual compute node, use the following command on your Linux terminal:

    $ ssh username@hostname

  • That’s it. You should be now able to log in to the remote machine without a password.

Windows Users​

Password-based authentication is very insecure and vulnerable to bot-nets trying to guess user names and passwords over the internet. Hence, we recommend key-based authentication to access the server. Please follow these steps to add your keys to the server:

Prerequisites​
