Title: Writing a dissector for wireshark Post by: bluecmd on June 05, 2011, 10:30:30 AM Hello.
After playing a bit with writing a python implementation of the protocol (extending pybitcoin) I find it very frustrating that I am unable to debug my packets. A quick scan around the wiki, IRC and forums revealed that no-one has stepped up to produce one, but I am going to write a wireshark dissector. Hopefully this will make the life of alternative implementations developers a bit easier. I'll keep you posted - I should have something basic working by the end today or tomorrow and continue to extend it as I go along.

Currently supporting version, verack and addr messages. Title: Re: Writing a dissector for wireshark Post by: blap on June 06, 2011, 12:04:40 AM :)

https://github.com/phantomcircuit/bitcoin-alt I think it is almost complete. The only thing that it is missing is the verify signature stuff in the scripting language.

Thank you!https://github.com/phantomcircuit/bitcoin-alt I think it is almost complete. The only thing that it is missing is the verify signature stuff in the scripting language. It will do nicely in testing the dissector. Title: Re: Writing a dissector for wireshark Post by: bluecmd on June 06, 2011, 06:30:00 PM Success!
Every message except for IP transactions, alert and headers are handled. The reason why these are not implemented is that I cannot verify that they behave like the documentation. I will extend this as we go along, but this will hopefully help people debug their clients and such.
