I have cut an pasted the Windows Makefile.nmake below from the developer
guide.
My dissector is the sample one from the guide, and I have stuck with the
name foo.
I think I have followed the edits in README.plugins correctly, but I am not
familiar with nmake and I get lost at section 4.

The protocol I want to dissect ' foo' is contained within the data of a UPD
packet.
Normall Wireshark would display the UPD packet showing it has a length of 44
bytes and displaying its source and destination. It would also show that the
UDP packet contains 36 bytes of data (which is where my pr
ction. In particular, you should read readme.DEVELOPER,
readme.PLUGINS, and readme.DISSECTORS (the latter is critical).
The dissectors one is long, but worth the read.

I would like to give users of my dissector a quick and easy way to find any
packets that have been sent which are not of the expected size. To me, as a
newbie, the obvious way to do this would be to allow them to filter packets
based on expected and actual packet sizes.
To do that I think I ne
Thanks for the solution, I had the same problem.
Its probably a good idea to also put;
item=proto_tree_add_uint(my_tree, hf_my_item, tvb, offset, length,
my_item_value);
PROTO_ITEM_SET_GENERATED(item);
That way Wireshark puts square brackets round the field to show it is
calculated.
If you se
e too long as malformed,
that way all packets of the wrong length can be caught with one filter?

In hf_register_info I declare a field to be FT_UINT16.
Then I use "proto_tree_add_item" to put it on the tree.
In the lower (3rd) pane Wireshark dispalys the two bytes in hex as;
24 00
In the middle (2nd) pane it displays the value of the field as 9216 when
what I was wanting to see was 36.

Is there a way to get a dissector to run on all ports?
So far I have been explicitly adding it to a specific port e.g.
dissector_add("tcp.port",1234,handle);
TIA
Hal
P.S. Guy thanks for answering an earlier post I did not reply because I have
been ill, I just use 'foo' as the protocol name
dissectors?
Once a dissector is heuristic will it just look on all ports?

A work around with the current release is just simply to disable the
dissector of the protocols you're not interested in. This largely improves
the experience with current heuristic dissectors.

I want to do this so that I can use preferences properly.
I might also want to do it if another heuristic dissector is wrongly
grabbing packets (not happening at the moment) that should be coming to me.
The example in README.developer shows;
It's disable, not delete. And what's even

I start Wireshark (don't open a file or anything).
My dissector's proto_reg_handoff routine is called.
In the code that runs only once I initialise a variable
static gboolean prefTick
to TRUE, and register the preference.
Before returning the variable is printed out and it is TRUE.

Hi,
Question: is our preference already in the preferences file?
Then your default gets overwritten by this stored value. The default is
default only when the preference is newly introduced.
Thanx,

You might try checking Help->About Wireshark->Folders. Specific
locations vary by platform and compile-time options.

Hi Tom,
I am just starting to learn how to use Wireshark myself (it used to be
Ethereal),messing about with a protocol sent within TCP.
You should probably start by downloading Wireshark and running it on your
network to see what it does. It will capture and decode the TCP which it
knows abo
"proprietery". However, to dissect the protocol, I think

Hi,
There are various routines to get things like "tvb_get_stringz" and
"tvb_get_ntohieee_float"
What do you use to get a boolean, I have not found anything?
