I need a low level packet debuger or something else that shows what a packet do

Any suggestion?
Thx
there is a debug variable in the sock structure that you can enable at
various points, and use in instrumentation to conditionally print out
data at various points. I usually turn in on in sys_socket, or
sys_connect, etc, based on information I have on hand at the time
(process name, dest ip, etc). That allows me to print out data for a
particular socket as its datagrams traverse the IP stack.
