| Abstract: | This paper analyzes the Netfilter location and structure in the IP protocol stack and introduces the mechanism and method of exptending the Netfilter-iptables target option by applying the patch-o-matic structure.Finally,a simple example is presented to illustrate how to customize output target to analyze and output the network stack so as to analyze and survey the network data packet in different node. |
