# Build your own cloud desktop

## What you'll need:
* A linux instance, preferably with at least 4GB of RAM
* XQuartz (macOS users only)
* X2Go client installed (Windows, macOS, or Linux)
* A terminal with an OpenSSH client (built-in for macOS and Linux users, use WSL for Windows)
* Windows Services for Linux (Windows users only): https://learnlinux.link/wsl-dl

## Links:
* Linode (cloud provider used in this example): https://linode.com
* XQuartz (macOS users only): https://learnlinux.link/xquartz
* X2Go client: https://learnlinux.link/x2go-dl

## Commands used

### Add a user for yourself
adduser <desired-username>

### Add your user to the sudo group
usermod -aG sudo <username>

### Log in as your new user
First, log out:
exit

Then, log in as your new user:
ssh <user>@ip

### Set the hostname
Edit the hostname file:
sudo nano /etc/hostname

Change the name to whatever you want the name of your server to be.

Also, update the hosts file with your chosen hostname as well:
sudo nano /etc/hosts

### Install updates
Update the package repository index:
sudo apt update

Install all updates:
sudo apt dist-upgrade

### Reboot the server
Now that all the updates are applied, we've created a user for yourselves, and we've updated the hostname, we should reboot the server. That was a lot of change! Run the reboot command to reboot the server:
sudo reboot


### Security
#### Install the unattended upgrades package:
sudo apt install unattended-upgrades

#### Verify that it's running:
systemctl status unattended-upgrades

#### Adjust configuration for unattended upgrades:
sudo nano /etc/apt/apt.conf.d/50unattended-upgrades

#### Enable automatic reboot:
//Unattended-Upgrade::Automatic-Reboot "false";
Uncomment by changing to:
Unattended-Upgrade::Automatic-Reboot "true";

Also uncomment:
Unattended-Upgrade::Automatic-Reboot-WithUsers "true";


#### Set a time for the automatic reboot to happen:
// Unattended-Upgrade::Automatic-Reboot-Time "02:00";
Change to (and adjust with your desired time):
Unattended-Upgrade::Automatic-Reboot-Time "04:00";

#### Verify automatic updates are fully enabled:
sudo nano /etc/apt/apt.conf.d/20auto-upgrades

Ensure both are set to 1.

curl -s https://packagecloud.io/install/repositories/crowdsec/crowdsec/script.deb.sh | sudo bash
