ll26env

PWN lab environment for Linux binary exploitation.

Tip: Extend idle timeout to 4 hours in GitHub Settings → Codespaces to prevent auto-sleep.

How To Run Environment

1. Click the button below:

2. Wait for setup (~2 min with prebuilds)

3. Wait for "ENVIRONMENT IS READY" message in terminal

Local alternative: Install Docker + Dev Containers extension, then open in VS Code

How To Work In Environment

Local (recommended)

Better performance with local software:

VS Code Desktop:

1. Install VS Code + GitHub Codespaces extension
2. Ctrl+Shift+P → "Codespaces: Connect to Codespace"

SSH tunnel (alternative):

gh codespace ssh -- -L 5901:localhost:5901

Both methods forward ports to localhost. Then connect VNC client to localhost:5901:

• TigerVNC or RealVNC

RealVNC color fix: Properties → Expert → ColorLevel = full

Remote (browser only)

Zero setup - everything in browser:

1. Copy the desktop link from terminal output (it auto-connects)
2. Or open Ports tab in VS Code (bottom panel) → click globe icon on port 6080 → click Connect
