Dish is a lightweight command-line tool written in Go for monitoring HTTP and TCP sockets. It aims to be a simpler alternative to tools like netstat and ss by providing a clear, real-time view of active connections, including details like the process using the socket, remote addresses, and connection state. Dish focuses on ease of use and minimal dependencies, making it a quick and convenient option for troubleshooting network issues or inspecting socket activity on a system.
A new open-source tool called "Dish," written in the Go programming language, has been introduced as a lightweight solution for monitoring HTTP and TCP sockets. Designed for simplicity and ease of use, Dish aims to provide developers with a quick and efficient way to inspect network traffic flowing through their applications. It achieves this by acting as a proxy, sitting between the client and server, and displaying the intercepted data in a user-friendly format. The tool's lightweight nature stems from its minimalistic design and focus on core functionalities, avoiding unnecessary bloat and dependencies.
Dish supports both HTTP and raw TCP connections, allowing users to monitor a wider range of network interactions. For HTTP traffic, Dish can display detailed information such as request headers, request bodies, response headers, response bodies, and timing metrics. This granular level of detail can be invaluable for debugging web applications, identifying performance bottlenecks, and understanding the flow of data. For raw TCP connections, Dish displays the raw byte streams exchanged between the client and server, enabling users to analyze lower-level network protocols and troubleshoot connectivity issues.
The project is hosted on GitHub and is readily available for anyone to download, use, and contribute to. The Go implementation likely contributes to its cross-platform compatibility and efficient performance. While the precise installation and usage instructions are detailed in the GitHub repository, the overall aim of the project is to provide a readily accessible and easy-to-use tool for developers needing a straightforward way to gain visibility into their network communications without complex setup or heavy resource consumption. This makes it a potentially valuable addition to the toolkit of any developer working with network-based applications.
