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.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
