Thanks a lot for your response it really give more insight into it, I just
want to ask one more thing is it like for each protocol we have all its
attribute at one level like suppose ethernet, so all ethernet attributes
at one level than in next level all IP attributes like that.

Re: [Wireshark-dev] tvb buffer
The pcap library collects the data from the operating system. That
gets passed to wireshark and the tvb is created.

I know that in wireshark when a farme is selected the top level dissector
is called like ethernet which in turn calls other dissectors. But I really
want to know where is this buffer tvb constructed for the first time which
is than passed to subsequent dissectors. Is it constructed from the raw
understanding
the code.
I appreciate your help in advance.

The "doc" directory in the wireshark distribution has lots of good

If this is the case, then I wouldn't
ould be able to use -R instead of -f, but note that this uses more
processing than -f, so if the packets are coming in fast, you might lose
some.
If you can use a UDP port number, then you can use -f 'udp port XXX' as
your capture filter.

ible. You can only
use 'contains' in the display filter syntax, which is unique to wireshark
(and tshark, etc.)

#x27;re really using the "contains" keyword? That's for strings and

The spaces in your filter are probably confusing the shell when you
invoke wireshark/tshark from the command-line. Are you running on
Unix? Use single quotes around your filter:
tshark .
I want to set command line filter expression for proprietary protocol that
is registered over UDP by its name. I am able to do it directly in
Wireshark GUI by setting the expression as "UDP contains my_protocol", but
I need to do the same from command line that I am unable to do right now.
