 120 <h2>Abstract</h2>
 121 <p>
 122 netsniff-ng is a free, performant Linux networking toolkit.
 123 <br><br>
 124 The gain of performance is reached by zero-copy mechanisms, so that on packet reception <i>and</i> transmission the kernel does not need to copy packets from kernel space to user space and vice versa.
 125 <br><br>
 126 For this purpose, the netsniff-ng toolkit is libpcap independent, but nevertheless supports the pcap file format for capturing, replaying and performing offline-analysis of pcap dumps. Furthermore, we are focussing on building a robust and clean analyzer and utilities that complete netsniff-ng as a support for network development, debugging or network reconnaissance.
 127 <br><br>
 128 The netsniff-ng toolkit consists of the following utilities:
 129 <ul>
 130   <li><b>netsniff-ng</b>, a high-performance zero-copy analyzer, pcap capturing and replaying tool</li>
 131   <li><b>trafgen</b>, a high-performance zero-copy network traffic generator</li>
 132   <li><b>bpfc</b>, a Berkeley Packet Filter (BPF) compiler supporting Linux extensions</li>
 133   <li><b>ifpps</b>, a top-like kernel networking and system statistics tool</li>
 134   <li><b>flowtop</b>, a top-like netfilter connection tracking tool</li>
 135   <li><b>curvetun</b>, a lightweight multiuser IP tunnel based on elliptic curve cryptography</li>
 136   <li><b>ashunt</b>, an Autonomous System (AS) trace route and ISP testing utility</li>
 137 </ul>
 138 <p>
 139 (Note: <a href="http://www.tcpdump.org/">libpcap</a> starting from 1.0.0 now also supports zero-copy, but for capturing only! netsniff-ng's pcap files can also be opened with tools like <a href="http://www.wireshark.org/">Wireshark</a>, and vice versa!)
 140
 141 <h2>Development</h2>
 142 <p>
 143 <b>Source control</b>
 144 <p>
 145 There's a public Git repository at <a href="https://github.com/gnumaniacs/netsniff-ng">GitHub</a> where you can check out the entire code base. If you are curious about the latest development happenings, you really might prefer our Git master's branch instead of the tarballs within our <a href="http://pub.netsniff-ng.org/">public archive</a>. For tamper resistant downloading, clone the Git repository and checkout the corresponding version tag.
 146 <p>
 147 <b>Documents</b>
 148 <p>
 149 There is a netsniff-ng <a href="faq.html">frequently asked question</a> site and for participating in development have a look at the documentation files within the source code. <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html">Here</a> is also a FAQ about the GNU GPL version 2, under which netsniff-ng is licensed.
 150 <p>
 151 For reporting bugs please use our <a href="http://bugs.netsniff-ng.org/">bug tracking system</a> or write an e-mail to <script type="text/javascript">InsertMail("bugs", "netsniff-ng", "org");</script>.
 152 <p>
 153 <b>Contribute</b>
 154 <p>
 155 If you think this software is great, then please consider <a href="http://flattr.com/thing/421382/gnumaniacs-devs" target="_blank">donating</a> (Flattr) some money to help us to keep up development, server fees, or travelling costs for conferences. If you would like to help otherwise, we would like to see more people to:
 156 <ul>
 157   <li>Review and contribute to the <a href="https://github.com/gnumaniacs/netsniff-ng">source code</a> (see <a href="https://github.com/gnumaniacs/netsniff-ng/blob/master/Documentation/Projects">projects</a> file)</li>
 158   <li>Add or improve documentation, Man-pages, write interesting howtos</li>
 159   <li>Maintain distribution specific packages</li>
 160   <li>Donate hardware, networking equipment, especially for 10-Gbit/s-Ethernet</li>
 161   <li>Test netsniff-ng on your specific platform, especially on non-x86</li>
 162 </ul>
 163 <p>
 164 Currently, netsniff-ng is only available for Linux platforms. If you have a port for *BSD, let us know for merging your port into the main source tree. However, please do NOT PORT netsniff-ng to Windows or other proprietary crap! (Here is a nice explanation why; we really share <a href="http://www.fefe.de/nowindows/">Felix von Leitner's point of view</a>.)
 165
 166 <h2>Documentation</h2>
 167 <p>
 168 The man page of each stable release of netsniff-ng will cover all of the usage details. It is included within the source code distribution package. We also have a <a href="faq.html">frequently asked question</a> page. Furthermore, the documents within the <a href="https://github.com/gnumaniacs/netsniff-ng">repository</a> will give you some useful information.
 169 <p>
 170 To dig into the inner workings of the Berkeley Packet Filter architecture, have a look at <a href="bpf.pdf">this</a>.
 171 <p>
 172 Documentation about the ``packet_mmap'' architecture with ``pf_packet'' sockets for the Linux kernel can be downloaded from <a href="http://www.kernel.org/">kernel.org</a> under <a href="http://lxr.linux.no/linux+v3.2.9/Documentation/networking/packet_mmap.txt">packet_mmap.txt</a>.
 173 <p>
 174 If you need the netsniff-ng logo in vector format, feel free to use them from our repository either in <a href="https://github.com/gnumaniacs/netsniff-ng/blob/master/contrib/art/netsniff_logo3_paths.pdf">black</a> or <a href="https://github.com/gnumaniacs/netsniff-ng/blob/master/contrib/art/netsniff_logo3_paths_white.pdf">white</a>.
 175
 176 <h2>Support</h2>
 177 <p>
 178 A mailing list for netsniff-ng moderated (spam free) user discussions is open to the <a href="http://groups.google.com/group/netsniff-ng">public</a>. Subscribe and mail to <script type="text/javascript">InsertMail("netsniff-ng", "googlegroups", "com");</script>. There's also an archive at <a href="http://dir.gmane.org/gmane.linux.network.netsniff-ng">Gmane</a> and a <a href="http://www.mail-archive.com/netsniff-ng%40googlegroups.com/">searchable archive</a>.
