Hmm - the only think I have used in the past is tcpdump/libpcap from http://public.lanl.gov/cpw/ Documentation/networking/packet_mmap.txt also seems to be a little dated, but does have some code snippets if you wanted to make something lightweight... Does anyone else on netdev have a small test app? -Robin - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
