Linux network packet sniffer toolkit

netsniff-ng is a high performance Linux network sniffer for packet inspection. It can be used for protocol analysis, reverse engineering or network debugging. The gain of performance is reached by 'zero-copy' mechanisms, so that the kernel does not need to copy packets from kernelspace to userspace. netsniff-ng toolkit currently consists of the following utilities: * netsniff-ng: a zero-copy packet analyzer, pcap capturing/replaying tool * trafgen: a multithreaded low-level zero-copy network packet generator * mausezahn: high-level packet generator for appliances with Cisco-CLI * ifpps: a top-like kernel networking and system statistics tool * curvetun: a lightweight curve25519-based multiuser IP tunnel * astraceroute: an autonomous system trace route and DPI testing utility * flowtop: a top-like netfilter connection tracking tool * bpfc: a [seccomp-]BPF (Berkeley packet filter) compiler, JIT disassembler
