I don't know of a tutorial, but you can read about BPF (Berkeley Packet Filter) on the TCPDump man page at: http://www.tcpdump.org/tcpdump_man.html You will quickly see that there is really no need to know hex unless you are doing some complex filtering...

Reading the man page has me crossing my eyes and growning. I want to capture udp packets on port 53 to one host, including the entire payload. I've figured out the hex address for the host, but the rest escapes me.
