Hi, I have written LUA scripts which dissect proprietary packets from network. I had written the lua scripts as *-- declare our protocol InDirectnip_proto = Proto("INIPD","NIP","NIP Messages") -- create a function to dissect it function InDirectnip_proto.dissector(buffer,pinfo,tree) pinfo.cols.protocol = "INIPD" end -- load the udp.port table udp_table = DissectorTable.get("udp.port") -- register caicd direct mip protocol to handle udp port 50019 udp_table:add(50013,InDirectnip_proto) * I need help to get the following a) How can I get the source ip address of packets in this script file I tried to get the ip address as *print(Field.new("ip.addr")) *but i got the error "A Field extractor must be defined before Taps or Dissectors get called" in wireshark. Please help me how to define extarctor before dissectors gets called. b) is there any way to register multiple udp port in single lua file? Thanks in Advance Awadhesh.
