netsniff-ng is a high performance command line packet analyzer written for Linux. In contrast to tcpdump and other libpcap-based packet analyzers, netsniff-ng maps incoming frames directly into a circular receive buffer that can be accessed from user space without copying between address spaces. It can be used for debugging the local network, measuring performance throughput, or creating network statistics of incoming packets on central network nodes like routers or firewalls.
