First: what the ***** is an SSH tunnel? Well, it’s basically a fancy way to securely connect to another computer over the internet using Secure Shell (SSH) protocol. This can be super helpful when you need to debug code on a remote server or access resources that are only available locally.
Now lets get down to business! Heres how to set up an SSH tunnel for remote debugging in VS Code:
1. Open your terminal (or command prompt) and navigate to the directory where you have your Python code saved.
2. Connect to your server using SSH by running this command: `ssh -i [your_private_key] [username]@[server_ip]`
3. Once connected, open VS Code and create a new project or navigate to the directory where you have your code saved.
4. Open the terminal in VS Code by clicking on Terminal > New Terminal (or Ctrl + Shift + `) and run this command: `export PS1=’\u@\h:\w$ ‘`
5. This will change your terminal prompt to display your username, server name, and current directory.
6. Now let’s set up the SSH tunnel! Run this command in your terminal: `ssh -i [your_private_key] -L [local_port]:[server_ip]:[remote_port] [username]@[server_ip]`
7. This will create a local port on your machine that forwards to the remote server’s specified port.
8. In VS Code, open the Debugger settings by clicking on File > Preferences > Settings (or Ctrl + ,) and add this configuration: `”remote.SSH.gateway”: “localhost”, “remote.SSH.host”: “[server_ip]”, “remote.SSH.username”: [username], “remote.SSH.auth.userKnownHostsFile”: “/dev/null”`
9. This will allow VS Code to connect to the remote server through your SSH tunnel and debug code on that machine.
10. Save your settings, open a Python file in VS Code, set up some breakpoints, and hit F5! You should now be able to step through your code on the remote server using VS Code’s built-in debugger.
And thats it! With this setup, you can easily debug code on any remote server without having to worry about setting up a separate debugging environment or exposing sensitive data over the internet.
