I want to call PPPoED and PPPoES dissector from my lua plugin. But I am getting "Dissector_get: No such dissector" error.
After some searching I found that a protocol should register with register_dissector() in wireshark code to be available in lua script.
Wondering why these protocols are not registered as dissectors?
Similar question with a potential work around at the end.
Could you back into it via ETHERTYPE_PPPOED and ETHERTYPE_PPPOES ?
dissector_handle_t pppoes_handle =
create_dissector_handle(dissect_pppoes, proto_pppoes);
dissector_add_uint("ethertype", ETHERTYPE_PPPOES, pppoes_handle);
Thanks. It worked with following code in a lua script.
local eth_d = DissectorTable.get("ethertype")
local pppoed_d = eth_d:get_dissector("0x8863")
pppoed_d:call(buffer(cur):tvb(), pinfo, tree)
local udp_d = DissectorTable.get("udp.port")
local l2tp_d = udp_d:get_dissector("1701")
l2tp_d:call(buffer(cur):tvb(), pinfo, tree)
