Hi, Team
I am building a custom LUA dissector invoking a built-in HART-IP dissector embedded with Dissector.get("hart-ip") command but it returns nil (nothing). I'HART-IP is also missing in Dissector.list() output.
Is there any to call HART-IP dissector in LUA ?
POC (possibility for improvement?)
easypost_hartip_f = Field.new("hart_ip")
local hartip_fi = easypost_hartip_f()
local tcp_dtable = DissectorTable.get("tcp.port")
tcp_dtable:try(5094, tvb:range(hartip_fi.offset):tvb(), pinfo, tree)
Hi!
Thanks, but the first line returns error "bad argument #1 to 'new' (Field_new: a field with this name must exist)"
A Field object can only be created outside of the callback functions of dissectors, post-dissectors, heuristic-dissectors, and taps.
A FieldInfo object can only be used within the callback functions of dissectors, post-dissectors, heuristic-dissectors, and taps.
Are you accessing it inside a dissector or tap? Will not work in the Lua->Evaluate window.
