I am writing a kernel module that captures packet at the netfilter pre - routing hook. I only want to capture the BEACON FRAME. I have few queries: 1>When the beacon frame comes to receiving machine do the sk_buff gets allocated? 2> How can i identify the beacon frame at the pre routing hook? 3> Beacon frame consist of a string for authentication of client with the server, can i use sk_buff pointers to get access to that string, if sk_buff is allocated? Regards Gunjan These beacon frames do not appear to be IP packets. If that is true, I don’t think you are going to see them in any netfilter hooks. Jeff Haran
