Implementing Application Layer Packets
Z0rdak opened this issue · 1 comments
Hey there,
I have found your repo while searching for an Implementation/Wrapper of pcap für .NET for a university project.
I am thinking about extending your work/contribute to your work by writing some Dissectors/Packets for some Application Layer Protocols. Namely, HTTP, MQTT and maybe OPC UA.
Before I start, I just want to make sure I know my way around in your code. So I was wondering what would be the class to extend for my purposes. The mentioned protocols are all TCP based (some also support UDP, but that's not what my focus is about).
My guess is to start by extending TransportPacket to implement my Packets - is this correct, or is there another Type for this purpose I missed?
Also, are there any examples for implementations of Application Layer Packets which I could follow?
And finally, are there any contribution guidelines?
Best regards
That would be appreciated. The class you need to extend is Packet. TransportPacket is only for packets with a source/destination port.
There are no guidelines, but you might find this useful: https://github.com/dotpcap/packetnet/blob/master/ArchitectureNotes. Also checking some existing classes to see how they're structured is a good way to start. Furthermore, if possible, properties should be possible to set as well.
