dtrace discuss - Feb 2008 - DTrace Toolkit tcpsnoop

I sent this to Brendan but never got a response.  Maybe someone else
can help?

-----

Hi Brendan.  I''m trying to debug a problem where I need to snoop the
network traffic over a punchin connection, where snoop doesn''t work.
I found your tcpsnoop dtrace tool, which seemed like it might be able
to do what I need.  Unfortunately, it doesn''t seem to have an option
to dump out the data from the packets.  Does the dtrace provider allow
access to the entire data packet?  Is it possible to modify tcpsnoop
to dump out the data?  I don''t know dtrace at all so any help you can
offer to point me in the right direction would be appreciated.

I''m running S10U4 on this machine, if it matters.

Hi Bill,

At the minute we don''t have an in-built mechanism for dumping the
data in a packet. There is an RFE which may be of interest:

6314638 Dtrace needs a packet dumper

For now you''d have to roll something yourself to get this done.

Jon.
