**Course Title:** Mastering Development Environments **Section Title:** Remote Development Environments **Topic:** Connect to a remote server and set up a development environment using SSH.(Lab topic) **Objective:** In this hands-on lab, you will learn how to connect to a remote server using SSH and set up a development environment. By the end of this lab, you will be able to securely access a remote server, configure your development environment, and start coding remotely. **Prerequisites:** Before starting this lab, ensure you have the following: 1. Basic knowledge of Linux command-line interface (CLI) 2. A remote server with SSH enabled (e.g., AWS EC2, DigitalOcean Droplet, or a local VM) 3. SSH client installed on your local machine (e.g., OpenSSH, PuTTY, or SSH in your terminal) 4. A text editor or IDE with SSH support (e.g., VS Code, IntelliJ, or Sublime Text) **Step 1: Set up your SSH client** If you're on a Windows machine, you may need to install an SSH client like PuTTY ([https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)) or use the built-in Windows Subsystem for Linux (WSL) with OpenSSH. For macOS and Linux users, OpenSSH is likely already installed on your system. You can verify this by running `ssh -V` in your terminal. **Step 2: Generate SSH keys (if you don't have any)** If you don't have SSH keys, generate a new pair using the following command: ```bash ssh-keygen -t rsa -b 4096 ``` This will create a new RSA key pair with a 4096-bit key size. Follow the prompts to choose a location for your keys and set a passphrase. **Step 3: Copy your public SSH key to the remote server** Use the `ssh-copy-id` command to copy your public key to the remote server: ```bash ssh-copy-id username@remote_server_ip ``` Replace `username` with your actual username on the remote server, and `remote_server_ip` with the IP address of your remote server. **Step 4: Connect to the remote server using SSH** Use the following command to connect to the remote server: ```bash ssh username@remote_server_ip ``` You will be prompted to enter your password or passphrase (if you set one). If everything is set up correctly, you should now be logged in to your remote server. **Step 5: Set up your development environment** Once you're logged in to the remote server, create a new directory for your project and install the necessary tools (e.g., Git, Node.js, or Python): ```bash mkdir myproject cd myproject git init npm init ``` Replace `myproject` with your actual project name. **Step 6: Configure your text editor or IDE for remote development** If you're using VS Code, install the Remote Development extension ([https://code.visualstudio.com/docs/remote/remote-tutorial](https://code.visualstudio.com/docs/remote/remote-tutorial)). For other text editors or IDEs, consult the official documentation for SSH support and remote development setup. **Conclusion:** In this lab, you learned how to connect to a remote server using SSH and set up a development environment. You can now work on your projects remotely, collaborate with team members, and enjoy the benefits of a cloud-based development environment. **Practice and reinforce your skills:** Try connecting to a different remote server or a local VM using SSH. Experiment with different SSH clients and text editors or IDEs. Explore advanced SSH features like port forwarding and tunneling. **Leave a comment or ask for help:** If you encountered any issues or have questions during this lab, please leave a comment below.
