netsniff-ng toolkit

netsniff-ng is a free Linux networking toolkit, often described as a Swiss army knife for your daily Linux network management tasks.

Performance gains are achieved through zero-copy mechanisms. This means that when packets are received or transmitted, the kernel does not need to copy them between kernel space and user space, which enhances efficiency. Our toolkit is designed for various purposes, including network development and analysis, debugging, auditing, and network reconnaissance.

The netsniff-ng toolkit includes the following utilities: - netsniff-ng: a fast, zero-copy analyzer and tool for capturing and replaying pcap files. - trafgen: a multithreaded, low-level network packet generator that uses zero-copy techniques. - mausezahn: a high-level packet generator designed for hardware and software appliances, featuring Cisco-CLI compatibility. - bpfc: a compiler for Berkeley Packet Filters, along with a Linux BPF JIT disassembler. - ifpps: a tool similar to top, which provides kernel networking statistics. - flowtop: a netfilter connection tracking tool that operates similarly to top. - curvetun: a lightweight IP tunnel based on the curve25519 encryption method. - astraceroute: a utility for performing autonomous system (AS) trace routes. You can obtain it via Git using the following command: git clone git://github.com/netsniff-ng/netsniff-ng.git Note (*): We have taken over further maintenance and development of mausezahn. Download and Release Notes: Generally, the latest development version from our Git repository is stable and includes new features. Occasionally, we also create stable snapshots from our Git tree, which we announce on our mailing list.

The current stable release version of netsniff-ng is 0.6.7.
