Thanks.

Yes, can confirm. Juliusz has likewise been most insistent on not giving any hints.

Well, basically taking the above paragraph and putting it in an appendix as "things to test for" would be useful. I.e. some list of "make sure these scenarios work and you should be set". For the packet format, I targeted having wireshark agree with me on the contents of the packets.

It'll be instructive, annoying and fun, I expect :) -Toke _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
