3 netsniff-ng - the packet sniffing beast
5 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
7 netsniff-ng is is a free, performant Linux network analyzer and networking
10 The gain of performance is reached by 'zero-copy' mechanisms, so that the
11 kernel does not need to copy packets from kernelspace to userspace and vice
14 For this purpose netsniff-ng is libpcap independent, but nevertheless supports
15 the pcap file format for capturing, replaying and performing offline-analysis
16 of pcap dumps. Furthermore we are focussing on building a robust, clean and
17 secure analyzer and utilities that complete netsniff-ng as a support for
20 netsniff-ng can be used for protocol analysis, reverse engineering and network
21 debugging and currently consists of the following tools:
23 * netsniff-ng: the 'zero-copy' sniffer itself
24 * trafgen: a powerful 'zero-copy' network packet generator
25 * ifpps: a top-like kernel networking statistics tool
26 * curvetun: a lightweight curve25519-based multiuser IP tunnel
27 * ashunt: an AS trace route utility (todo)
28 * bpfc: a tiny BPF compiler (todo)
30 For any questions or feedback about netsniff-ng you are welcome to leave us a
31 message to <workgroup@netsniff-ng.org>. This project is purely non-commercial
32 and will always stay that way! netsniff-ng is developed by Daniel Borkmann and
35 Also, have a look at our FAQ [2] for answering your questions. Furthermore,
36 we have a development blog [3] where we sometimes drop some interesting things
37 or news for the outside world! A public repository of the old stable releases
38 (which you probably do not want to have a look at), can be found here [4]. A
39 probably not so much up-to-date benchmark is available to the public [5], too.
41 Sometimes we also hang out in IRC at #netsniff-ng on freenode.org. A mailing
42 list for netsniff-ng moderated (spam free) user discussions is open to the
43 public, too. Subscribe and mail to <netsniff-ng@googlegroups.com>.
45 You might want to have a look at NOTE, INSTALL, REPORTING-BUGS, HACKING,
46 CODING, FAQ, PATENTS and COPYING, too. Good lord, so much to read! Anyways,
47 enough talking from my side and happy packet hacking!
