Implement Your Own ICMP Ping Tool in Rust

Implement Your Own ICMP Ping Tool in Rust

Master low-level network programming by building your own ping tool from scratch. This project-based course teaches you everything about ICMP protocol implementation, raw socket programming, and cross-platform networking in Rust.

The ping utility is one of the most fundamental network diagnostic tools, yet few developers understand how it actually works under the hood. This course changes that by taking you through a complete implementation that rivals professional tools.

Deep Dive into Network Programming

You'll start with the fundamentals of the ICMP protocol and raw socket programming, then build a complete implementation that supports both IPv4 and IPv6. The course covers all the tricky details that production tools must handle: checksum calculations, proper timeout handling, and cross-platform compatibility.

What You'll Build

Your ping tool will include all the features users expect:

  • Support for both IPv4 and IPv6
  • Configurable packet size and interval
  • Detailed statistics and timing information
  • Proper error reporting and diagnostics
  • Cross-platform compatibility (Linux, macOS, Windows)

Real-World Networking Skills

The skills you learn apply to many networking projects:

  • Network diagnostic tools
  • Custom protocol implementations
  • Performance monitoring applications
  • Security scanning tools
  • IoT device communication

Low-Level Rust Programming

This course showcases Rust's capabilities for systems programming:

  • Safe handling of unsafe operations
  • Zero-copy packet parsing
  • Efficient memory management
  • Cross-platform abstractions
  • Error handling best practices

By the end, you'll have both a useful tool and deep understanding of how network protocols work at the lowest level.
