| Thread-topic: | filtering packtes before OS takes care about them |
Hi, i need a possibility to catch IP4 packets (from ethernet devices) before OS' netmodules (IP, UDP, TCP, ICMP, ARP, ROUTE, NETFILTER ...) takes care about them and * to delete them from input buffer such that OS' netmodules can't receive them * to modify packet headers and move packets to interface related output buffers * to keep them in input buffers such that OS' netmodules can take care about them. I would be thankfull for any hint, link or code example. Bye Matthias -- Dipl.-Inf.
