Sendp

Sendp is a network packet generator and analyzer written in Go. It is designed to be a versatile tool for network testing, security analysis, and troubleshooting. Sendp allows users to craft custom network packets with precise control over various protocol fields, including Ethernet, IP, TCP, and UDP headers. This capability makes it useful for simulating specific network conditions or testing the behavior of network devices and applications under various packet types.

Beyond packet generation, Sendp also functions as a packet sniffer. It can capture network traffic in real-time and display it in a human-readable format. The tool supports filtering captured packets based on criteria such as IP addresses, ports, or protocol types, enabling users to focus on relevant traffic. Sendp's ability to both send and receive packets makes it a valuable asset for performing various network diagnostics. For example, it can be used to test firewall rules, measure network latency, or identify unusual network activity. Its command-line interface provides flexibility for integration into scripts and automated testing workflows.
