Proj 6: Preparing an Ubuntu Server (10 pts.)

What you need:

A 64-bit computer of any kind, with virtualization software installed, such as VMware Player or VirtualBox.

Purpose

You need a 64-bit Linux machine to set up cryptocurrency miners for this and future projects, especially the projects using Multichain.

I recommend Ubuntu 16.04. You can use other versions of Linux if you wish, but the instructions will require modification.

Getting the Ubuntu ISO File

In a Web browser, go to

https://www.ubuntu.com/download/server

Download the latest version of Ubuntu 16.04. Save it in your Downloads folder. It will have a filename like ubuntu-16.04.1-server-amd64.iso.

Creating a Virtual Machine

Create a new virtual machine with at least 2 GB of RAM. Connect the virtual DVD file to the ubuntu-16.04.1-server-amd64.iso file. Boot up the machine, start it from the virtual DVD, and install the OS. Use a name and password you can remember--I used student for both the name and password.

The exact steps vary depending on your VM software. We have tutors in SCIE 214 who can help you create the VM if you don't know how to do it.

Alternative: Cloud Server

If you prefer, you can rent a virtual server on the cloud. You need at least 2 GB of RAM. You can rent a suitable machine for $20 per month from Digital Ocean, or from many other cloud providers.

Start your Server

Start your server and log in.

Execute the ifconfig command to see your IP address, as shown below.

You can control your server by typing directly into the console, but you can't copy and paste in commands, or scroll back, which is very inefficient. It's far better to use SSH.

Installing SSH

On your server, execute this command:

apt install openssh-server -y

Connecting with SSH

If you are using a Mac or Linux machine, SSH is already installed. If you are using Windows, download and install PuTTY.

Connect to your server with the username and password you chose when installing it.

Execute this command:

netstat -an | grep 22

You should see an ESTABLISHED connection on local port 22, as shown below.

Saving a Screen Image

Save a whole-desktop image showing the required items, as shown above.

YOU MUST SUBMIT A FULL-SCREEN IMAGE FOR FULL CREDIT!

Save the image with the filename "YOUR NAME Proj 6", replacing "YOUR NAME" with your real name.

Turning in your Project

Email the images to cnit.141@gmail.com with the subject line: Proj 6 from YOUR NAME. Posted 6-11-17
