Re: can tcpdump capture more than packet headers?

No excuses for ignorance but I have been playing with tcpdump to

still no joy. Can I capture data from the 'higher' layers(above network
layer on osi model)?

tcpdump can capture it all.
I'm uncertain how much tcpdump can dissect of NetBEUI, though.
Use -v, -vv, or -vvv to display additional info.
You may need to write to a file, then analyze with WireShark (or just
capture with WireShark).
