Here's some questions about libipq. 1. How to compile / install libipq? Is it necessary to recompile/install the latest version of iptables? Does iptables-1.2.9 include libipq? 2. How to get the individual man page of libipq? Here's a good manpage for: libipq:http://www.cs.princeton.edu/~nakao/libipq.htm But the detail superlink all refers to localhost/cgi-bin/man, are there any other ways to get them? 3. Libipq is one easy way for user application to communicate with kernel. If there exists multiple QUEUE targets, how does the kernel determine which is for which? Any suggestions is welcome. Thanks in advance.
