Hi, I'm a student at Tokyo Institute of Technology. I'd like to do following operations, and I thought do them with netfilter. But I don't know hot to do this actually. Could you tell me... - Can I do the following operations with netfilter? - If I can, how to do them? My purpose is to make the Linux Kernel believe that a packet has come. (In fact, any packet has not arrived.) I could do this without netfilter but with tunneling device as follows. [Any UserProcess] - [Kernel] - <Tunnel> - [Intermediate Process] - <Physical eth0> "Intermediate Process" usually passes any packet through, and send a packet into "Kernel" via "Tunnel" if necessary. Finally, I'd like to do this without tunneling device as follows. [Any UserProcess] - [Kernel] - ((???)) - [Physical eth0] At first, I thought that netfilter can act as ((???)) with my Kernel Module. But netfilter seems to be not able to generate packets out of nothing... Can I do this with netfilter? # If not, I'd like to know another way to do this... :-( Thanks, -- Dai MIKURUBE dmikurube@xxxxxxx
