Hello. I have a task which implies to read raw data from the network interface. I would be more than happy to have a "necessary and sufficient" piece of C code for proper opening of the network interface (bpf, ioctl?), reading packets from there (I guess read() is enough :), and having structure of the packet (detecting that it belongs to IP ones; which *.h files are to be included). A working example for monitoring IP packets is wanted mostly. Also, if you know good sources to read about that (books, url), please, share that info with me. Any help is Ok. Thank you in advance, Alexander. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
