Overview

This is an guide on how to set up a AWS EC2 free tier with GUI. The EC2 instance will be able to connect via Remote Desktop Protocol (RDP) or SSH.

You need to create a AWS account: https://portal.aws.amazon.com/billing/signup. You may need to provide your credit card information during the signup process.

Sign in to your AWS Account and go to the AWS EC2 Console: https://aws.amazon.com/console/

Create an AWS EC2

Set up the security groups

I suggest you define the security groups before setting up the instance. Setting up the security groups will give you a better understanding on what inbound/outbound traffic is allowed in the instances you are going to create.

Choose Security Groups at the left menu of your EC2 Dashboard. Create 2 security groups:

  1. rdp: Allow inbound traffic via port 3389
  2. ssh: Allow inbound traffic via port 22
  3. Allow all outbound traffic

Choose the OS, instance type and storage

Choose Services > EC2 from the menu. At the EC2 Dashboard, choose Instances.

Click the Launch Instance and choose the suitable AMI (Amazon Machine Image). Here I choose a t2.micro instance with Ubuntu Server 18.04 LTS image. Remember also choose the suitable Storage as not all kinds of storage are free. In this example I set up a 30GB General Purpose storage.

Image: Ubuntu Server 18.04 LTS

Instance Type: t2.micro

Click Review and Launch

Storage: 30GB General Purpose

Allow SSH and RDP connections

Choose the security groups created in the previous step:

Security Group: allow SSH and RDP

Create and download a .pem key file

You should create this key file. If you don’t create this and link it to the instance, you will not be able to connect to the instance via SSH or RDP. Here we create a new key file named ssh_private_key.

After that, click Download Key Pair and keep the key file save.

Do a chmod on the key file

You need to make sure that the ssh_private_key.pem downloaded is able to execute. Run chmod to change the permission:

❯ ll ~/Downloads/ | grep "ssh_private_key.pem"
[email protected] 1 BEN  staff   1.7K Jul  2 18:41 ssh_private_key.pem

❯ chmod 400 ~/Downloads/ssh_private_key.pem

❯ ll ~/Downloads/ | grep "ssh_private_key.pem"
[email protected] 1 BEN  staff   1.7K Jul  2 18:41 ssh_private_key.pem

Connect to EC2 via SSH

Once you click the Launch instance , you should be able to see your instance in running state in the web console. Then, you can connect to the EC2 via ssh using the pem key file. Assuming that your DNS name of your EC2 is ec2-0-1-2-3.ap-northeast-1.compute.amazonaws.com and it is running at ap-northeast-1 region, you can connect to it using user ubuntu:

❯ ssh -i ~/Downloads/ssh_private_key.pem [email protected]
The authenticity of host 'ec2-0-1-2-3.region-name.compute.amazonaws.com (0.1.2.3)' can't be established.
ECDSA key fingerprint is SHA256:8t8ey5IqoiGOKGc9WuDc5SXaYqFHPnKph1mRtzbQNTc.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

You need to confirm your fingerprint at the first connection attempt.

Welcome to Ubuntu 18.04.4 LTS (GNU/Linux 5.3.0-1023-aws x86_64)

Install a GUI and RDP

GUI: LXDE

I choose LXDE as the GUI of the ubuntu server: https://lxde.sourceforge.net/about.html.

LXDE is a new project aimed to provide a new desktop environment which is lightweight and fast

RDP: XRDP

xrdp is an open-source Remote Desktop Protocol server: http://xrdp.org

xrdp provides a graphical login to remote machines using RDP (Microsoft Remote Desktop Protocol)

Install the packages:

sudo apt-get update -y
sudo apt-get install lxde -y
sudo apt-get install xrdp -y

Set a password for your accout

You need to also set up a password for the ubuntu. This is for your later use in RDP as RDP only allows you to login an password-protected account.

sudo passwd ubuntu

Connect to EC2 via remote desktop

For mac user, you need to download the Microsoft Remote Desktop. If you are using Windows, you should already have the Remote Desktop application preinstalled.

Download Microsoft Remote Desktop

Launch the app and click Add PC:

Add PC in Microsoft Remote Desktop

Set the PC name (i.e. the DNS name of your machine):Set PC name

Login with user ubuntu and the password you set in the previous step.

Connect


Bonus Materials

1. Install additional IBus input method

If you want to type Japanese, Chinese, etc. you may need to install an input method. For cangjie, you can install Cangjians via the terminal:

sudo apt-get install ibus-cangjie

2. Install Midori browser from .deb package

Midori Browser is a browser web light, fast, secure, free software & open source

Download .deb file: https://astian.org/en/midori-browser/download/ or using wget:

cd ~/Downloads
sudo wget -qnc https://packages.astian.org/pool/main/m/midori/midori_9.0.0-1_amd64.deb
[email protected]:~/Downloads$ ll
total 1492
drwxr-xr-x  2 ubuntu ubuntu    4096 Jul  2 11:29 ./
drwxr-xr-x 17 ubuntu ubuntu    4096 Jul  2 11:22 ../
-rw-r--r--  1 root   root   1517328 Jan 11 23:26 midori_9.0.0-1_amd64.deb

After that, install the deb package using dpkg

sudo dpkg -i midori_9.0.0-1_amd64.deb

You may see the dependency problems like the following:

[email protected]:~/Downloads$ sudo dpkg --configure -a
dpkg: dependency problems prevent configuration of midori:
 midori depends on libpeas-1.0-0 (>= 1.15); however:
  Package libpeas-1.0-0 is not installed.
 midori depends on libxml2-utils; however:
  Package libxml2-utils is not installed.
 midori depends on gstreamer1.0-plugins-bad; however:
  Package gstreamer1.0-plugins-bad is not installed.
 midori depends on gstreamer1.0-libav; however:
  Package gstreamer1.0-libav is not installed.

dpkg: error processing package midori (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 midori

In this case, update the packages and reinstall midori:

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get update
sudo apt-get install midori

3. Set up a swapfile for better performance

[email protected]:~$ sudo fallocate -l 1G /swapfile
[email protected]:~$ sudo chmod 600 /swapfile
[email protected]:~$ sudo mkswap /swapfile
Setting up swapspace version 1, size = 1024 MiB (1073737728 bytes)
no label, UUID=9a121c2c-cd6f-48bf-b928-e550095a3efd
[email protected]:~$ sudo swapon /swapfile
[email protected]:~$ sudo swapon --show
NAME      TYPE  SIZE USED PRIO
/swapfile file 1024M   0B   -2
[email protected]:~$
sudo nano /etc/fstab
/swapfile swap swap defaults 0 0

After that, reboot the machine.

4. Use EC2 as a VPN server

Create a new security group allows all TCP and UDP inbound connections and add this security group to the EC2 instance:

EC2 instance inbound rules

Assign a security group

Install openvpn scripts

This repo contains scripts for VPN server set up and profile management. Install it into your EC2:

Download the script:

sudo apt update
sudo apt upgrade -y
mkdir ~/vpn && cd ~/vpn
wget https://git.io/vpn -O openvpn-install.sh
[email protected]:~/vpn$ ll
total 32
drwxrwxr-x  2 ubuntu ubuntu  4096 Jul  2 12:11 ./
drwxr-xr-x 19 ubuntu ubuntu  4096 Jul  2 12:11 ../
-rw-rw-r--  1 ubuntu ubuntu 23085 Jul  2 12:11 openvpn-install.sh

Make the openvpn-install.sh exectable in your EC2:

chmod +x openvpn-install.sh
sudo ./openvpn-install.sh

Add a new profile by running openvpn-install.sh:

Welcome to this OpenVPN road warrior installer!

This server is behind NAT. What is the public IPv4 address or hostname?
Public IPv4 address / hostname [18.183.12.213]:

Which protocol should OpenVPN use?
   1) UDP (recommended)
   2) TCP
Protocol [1]: 1

What port should OpenVPN listen to?
Port [1194]:

Select a DNS server for the clients:
   1) Current system resolvers
   2) Google
   3) 1.1.1.1
   4) OpenDNS
   5) Quad9
   6) AdGuard
DNS server [1]: 1

Enter a name for the first client:
Name [client]: demo-ec2-client

OpenVPN installation is ready to begin.
Press any key to continue...
Finished!

The client configuration is available in: /home/ubuntu/demo-ec2-client.ovpn
New clients can be added by running this script again.

Use another Terminal to download the .ovpn file. Assuming that the machine name is ec2-0-1-2-3.ap-northeast-1.compute.amazonaws.com and the generated .ovpn file is place under ~/:

scp -i sparkle.pem [email protected]:~/demo-ec2-client.ovpn ~/Downloads/demo-ec2-client.ovpn

Connect to the VPN

Pritunl Client is a easy-to-use OpenVPN client. Downlaod and install it.

Launch the client and click Import Profile:

Import ovpn profile

After that, click the burger menu of the profile and Connect.
