As I promised about 6 weeks ago here is the basic opennap protocol information that is to be used in creating the opennap side of the ourmx client , its not as complete as I would normally like but times against us in the coding dept so my apologies for not working on all of the possible packet exchanges.
A core development group member will be adding further data in the form of packet dumps to add to the textual information and those shall be added as they are received, if you see any errors or annoyances please let me know,
https://www.winmxworld.com/tutorials/ourmx_opennap_protocol.html Please take note that this guide has been written in the first instance for third party WPN developers and thus has its own style of presentation that might annoy a few opennap purists, however it will serve the purpose it was created for, namely to facilitate further client work and to stimulate further interest in opennap by third party developers.
