It may be that you haven't supplied a snaplen for tcpdump, so it's going
to truncate the packets at 68 (or 96) bytes. You'll be able to see
enough of the the transaction for ethereal to display it, along with
status codes and such, but it won't be complete. Try capturing with the
"-s 0" option.
That's it! Experience is essential, thanks for the pointer!

Nope. It's supposed to snoop at all the private data ;)
As it should be, discretion at the human layer.
