Wireshark-users: Re: [Wireshark-users] loading user specified decodes

My script loads with no errors, but it does nothing. What is wrong?

The script gets executed for sure. If I print out "asterix" variable, it says "Asterix", which is OK,
but after wireshark starts the user specific decode table is empty.

Here is my script (set_asterix.lua)
-- register asterix to handle specific ports do
    local udp_port_table = DissectorTable.get("udp.port")
    local asterix = udp_port_table:get_dissector(5000)
    udp_port_table:add(2061, asterix)
    udp_port_table:add(2062, asterix)
end

I do:
$./wireshark -X lua_script:set_asterix.lua

Another question is, how do I get a dissector by it's name, not by port?

yes Lua can help you for this:
the very first example in http://wiki.wireshark.org/Lua/Examples does it.
