# Remote Desktop Setup on DigitalOcean

## Overview
This project automates the deployment of a remote desktop environment on a DigitalOcean droplet using Terraform. It configures a Ubuntu 20.04 server with XFCE4, X2Go server for remote access, and a preconfigured user account.

## Features
- Deploys a DigitalOcean droplet in the `sgp1` region.
- Sets up a secure root password and a random password for the user `gabriel`.
- Installs XFCE4 as the desktop environment.
- Installs and configures X2Go for remote desktop access.
- Automatically provisions a 2GB swap file.

## Prerequisites
- [Terraform](https://developer.hashicorp.com/terraform/downloads) installed on your local machine.
- A [DigitalOcean account](https://www.digitalocean.com/) with an API token.
- SSH access to the deployed droplet.

## Deployment Steps

### 1. Configure Terraform
Edit `deploy.tf` and insert your DigitalOcean API token:
```hcl
provider "digitalocean" {
  token = "your_digitalocean_api_token"
}
```

### 2. Initialize Terraform
Run the following command to initialize Terraform and download the required providers:
```sh
terraform init
```

### 3. Apply the Configuration
To deploy the droplet, execute:
```sh
terraform apply -auto-approve
```
Terraform will:
- Create a DigitalOcean droplet.
- Generate secure passwords for root and `gabriel`.
- Run `setup.sh` to configure the system.

### 4. Retrieve Access Credentials
After the deployment, retrieve the droplet IP and passwords:
```sh
terraform output
```
Expected output:
```
droplet_ip = "xxx.xxx.xxx.xxx"
root_password = (sensitive value)
gabriel_password = (sensitive value)
```

### 5. Connect to the Droplet
#### Using SSH:
```sh
ssh root@<droplet_ip>
```
Use the root password retrieved from Terraform.

#### Using X2Go:
1. Download and install [X2Go Client](https://wiki.x2go.org/doku.php).
2. Set up a new session with:
   - Host: `<droplet_ip>`
   - Login: `gabriel`
   - Session Type: `XFCE`
3. Use the password retrieved from Terraform.
4. Connect to the remote desktop environment.

## Cleanup
To destroy the droplet and clean up resources, run:
```sh
terraform destroy -auto-approve
```

## Security Considerations
- The generated passwords are sensitive and should be handled securely.
- Remove the stored password file (`/home/gabriel/.password.txt`) after first login.
- Consider setting up SSH keys for better security.

## Troubleshooting
- Ensure the droplet is running: `terraform show`
- Check X2Go server logs: `sudo systemctl status x2goserver`
- Verify SSH authentication is enabled: `cat /etc/ssh/sshd_config | grep PasswordAuthentication`
