What do you mean "excluding the tpc"?

If you mean "excluding the TCP", what does that mean?  Do you mean  
"how do I define a capture filter that captures packets with HTTP  
traffic but doesn't capture ACK-only packets?"  (HTTP runs over TCP,  
with some rare exceptions, so literally "excluding the TCP" would  
exclude HTTP as well.)

For TCP over IPv4, see

	http://www.tcpdump.org/lists/workers/2005/11/msg00027.html

for an example of a filter that will capture only TCP packets with  
data (i.e., no ACK-only packets).
