can tcpdump capture more than packet headers?



Hi Guys,
No excuses for ignorance but I have been playing with tcpdump to
capture application data passing between two computers (no switch). All
that seems to be displayed is packet header information. The
client(-server) application is communicating using the netbios-ssn
(netbeui) protocol. I have tried increasing the packet size (using -s)
still no joy. Can I capture data from the 'higher' layers(above network
layer on osi model)?
Thanks,
Eddie
