👉 Overview
👀 What ?
Linux Node inspector and CEF debug are tools and techniques used for debugging applications in a Linux environment. Node inspector is a debugging interface for Node.js applications and CEF debug is a debugging mode for applications that use the Chromium Embedded Framework.
🧐 Why ?
Debugging is a critical process in software development and maintenance. It helps developers identify and fix errors in their code, leading to more reliable and efficient applications. Debugging is also crucial in cybersecurity as it allows security researchers to understand how malicious software operates and how to counter it.
⛏️ How ?
To use Node inspector, start your Node.js application with the --inspect flag. This will start the inspector and give you a URL that you can open in your browser to start debugging. For CEF debug, you can start your application with the --remote-debugging-port flag followed by a port number. You can then connect to this port with a browser to start debugging. Both these tools allow you to step through your code, set breakpoints, and inspect variables.
⏳ When ?
You should use Node inspector and CEF debug whenever you need to debug a Node.js or CEF application. This could be during development, when you are trying to understand how your code is behaving, or it could be during a security investigation, when you are trying to understand how a piece of malicious software is behaving.
⚙️ Technical Explanations
Node inspector works by running a WebSocket server inside your Node.js application. This server communicates with your browser, allowing you to interactively debug your application. CEF debug works in a similar way but instead of a WebSocket server, it runs a HTTP server that your browser can connect to. This server provides a JSON-based API that allows you to manipulate and inspect your application.
