Hi, I am trying to implement packet capturing in Linux-3.5.7. I have the procedure which works in Linux-2.4 , will the same procedure work on Linux-3.5.7 I am bit new to this , the procedure i am following is implementing Netfilter hooks capture the packets at several points of path in TCP/IP protocol stack NF_IP_PRE_ROUTING 1st hook NF_IP_LOCAL_IN 2nd hook NF_IP_FORWARD 3rd NF_IP_POST_ROUTING 4th NF_IP_LOCAL_OUT 5th Each hook is activated. Kernel modules can register to listen at any of these hooks. 1. NF_ACCEPT . 2. NF_DROP . 3. NF_STOLEN . 4. NF_QUEUE . 5. NF_REPEAT . does this procedure work with the new kernel version also now from user space i am going to use Libipq I for communicating with ip_queue. Please someone let me know if i am missing something, Regards, Blprasad.
