Hello all: I am a beginner to iptables. I want to get the header information (such as source ip, destination ip, and packet's length) of each packet pass through the filter. How can I get this information? I try to use "libipq", but I can't find a function to support this information. Would you give me a way ? thanks. ___ Bert Zhang +86-0451-6413683 Information Retrieval Lab School of CS Harbin Institute of Technology P.R.C.
