I've build a skype supernode probe utility and it will be run here shortly this evening. The intent is to determine exactly what versions of skype are offline by "speaking skype" and asking them for their client software version. I'm starting with the supernodes that ship within the obfuscated binary because almost all of these crashed simultaneously from what I've seen in my own code logs. I don't buy what the skype CEO is saying because first it was very many supernodes not a few also these went offline all around the same time and never came back up however if any are back online my utility will tell me. > > Anything that looked like a DoS after the outage started is easily > explained as clients attempting to reconnect. > > Matthew Kaufman > _______________________________________________ > p2p-hackers mailing list > p2p-hackers@lists.zooko.com > http://lists.zooko.com/mailman/listinfo/p2p-hackers _______________________________________________ p2p-hackers mailing list p2p-hackers@lists.zooko.com http://lists.zooko.com/mailman/listinfo/p2p-hackers
