Bitcoin wireshark 1.10.5 dissector with better support for the bitcoin protocol. Also DogeCoin/Litecoin support.
I was looking around for something to monitor my bitcoin traffic and figured there would be something out there for Wireshark. Unfortunately like much of the bitcoin source everything I could find was a couple years old and out of date.
The current dissector in 1.10.5 is really wrong and can't even decode some of the basic messages correctly. The dissector in the development tree has fixes for the basic messages but doesn't do much more than that.
So I spent a couple days poking at the source of the 1.10.5 dissector and came up with this. It's not perfect, in fact it's not even good but it's better than what I could find. I started it as a plug-in but then just switched to replacing the built-in dissector.
Additions over the existing dissector in 1.10.5:
Added Litecoin/Dogecoin magics Fixed correct parsing of version/verack messages Added parsing for commands: notfound,ping,pong,reject,alert
Installing ==
Download the 1.10.5 source...
replace the file epan/dissectors/packet-bitcoin.c found in the wireshark source directory with this one
make and sudo make install
you should be good to go...
If anyone wants to drag this over to the wireshark source tree feel free.
