Package netsniff-ng

Packet sniffing beast

http://netsniff-ng.org/

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.
