netsniff-ng: netsniff-ng netsniff-ng: netsniff-ng: netsniff-ng is a high performance linux network sniffer for packet netsniff-ng: inspection. Basically, it is similar to tcpdump, but it doesn't need netsniff-ng: one syscall per packet. Instead, it uses an memory mapped area within netsniff-ng: kernelspace for accessing packets without copying them to userspace. netsniff-ng: netsniff-ng: netsniff-ng: netsniff-ng: netsniff-ng:
