netsniff-ng-0.6.8-8.fc36.x86_64

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: the zero-copy sniffer, pcap capturer and replayer itself. trafgen: a high performance zero-copy network packet generator. ifpps: a top-like kernel networking and system statistics tool. curvetun: a lightweight curve25519-based multiuser IP tunnel. ashunt: an autonomous system trace route and ISP testing utility. flowtop: a top-like netfilter connection tracking tool. bpfc: a tiny Berkeley Packet Filter compiler supporting Linux extensions.
