Subject: [Wireshark-dev] Lua question for dissectors

Hi

Just a short question, can anyone point me into the direction on how to generate a sub-TVB in LUA from a reassembled 
stream?

We can display the data, but I want to have a sub-TVB displayed, and cannot figure out which method to use.

Cheers


Hi Roland,
Have you looked at the fpm.lua script available at https://wiki.wireshark.org/Lua/Examples?

After fpm_proto.dissector() does the reassembly, dissectFPM() is called, which simply does the normal tree:add(), for 
the given tvb:range(), i.e.:

    -- We start by adding our protocol to the dissection display tree.
    local tree = root:add(fpm_proto, tvbuf:range(offset, length_val))

Does that help?
