Hi,
I am trying to use Lua script to extract reassembled packet data in
wireshark. I have the required packet data stored in a variable with
userdata type. Now I need to print that data as a hex string to pass it over
stdout to another program.
Could someone please help me how to write a lua function to print out a
userdata variable as a hex string?
I have the following code to get the reassembled WSP payload out of packet
in wireshark
===================================
wsp_extractor = Field.new("wsp")
tap = Listener.new(nil,"wsp")
function tap.packet(pinfo,tvb)
local wsp_pdu = wsp_extractor()
if wsp_pdu then
-- print(tostring(wsp_pdu))
-- print ("PDU_LEN: " .. wsp_pdu.label)
end
end
===================================
Using either of the print statements results in error:
[string "wsp.lua"]:20: field cannot be represented as string because it may
contain invalid characters
Thanks.
