Hi, Below is the [3/3] kprobes-netpktlog-268-rc3.patch This patch provides network packet tracing using source and destination IP by trapping at various routines in the network stack.It demonstrates how a packet travels through the network stack, as suggested by Andi Kleen. Usage: Compile the kernel with options CONFIG_KPROBES, CONFIG_NETPKTLOG, CONFIG_NETFILTER, CONFIG_IP_NF_IPTABLES and CONFIG_IP_NF_TARGET_LOG enabled. You need to specify the parameters to the netpktlog module. To filter packets based on source and target ip, insert the module with source and target ip. $insmod netpktlog.ko netpktlog=@9.182.15.133,9.182.15.188 To filter packets based on only source ip, insert module with source ip. $insmod netpktlog.ko netpktlog=@9.182.15.133, To filter packets based on target ip, insert module with target ip. $insmod netpktlog.ko netpktlog=@,9.182.15.188 Please see the description of the patch for more details.
