One of the most basic ways of driving a computer, whether virtual or physical, whether remote or local, is using the command line. The command line of remote computers, which includes our Nectar virtual machines, can be accessed using a Secure SHell (or ssh) connection. It is called “Secure” because
ssh encrypts all its communications, and it’s called a
shell, because… well it appears that nobody really knows why it’s called a shell ###. Nevermind.
We can also access our instance using a webpage in the Nectar dashboard through a web-based
vnc-console gives us access to our instance command line, without the need for separate terminal software.
In this tutorial you will learn how to connect to our instance using terminal software and
ssh. We’ll set up a user account password to enable access to our
vnc-console, and then connect using the
This tutorial is part of the Nectar Cloud Starter curriculum. Only the bare essentials of
ssh-connecting are explained here. The
vnc-console is optional in the cloud starter curriculum, but it can be useful in the unlikely event of troubleshooting your instance.
What you’ll learn
- Connecting to our instance using
- Changing a User account password using

vncconsole in the Nectar Dashboard
What you’ll need
- Terminal software
- A running instance in the Nectar Cloud, with your public key and an
sshsecurity group applied
