Ah, now that's different. But again, it's reliable *enough*. It does leave a nice big hole for people like Nominum to prodyuce something that is *very* reliable.
You've been lucky.
Perhaps you've just been unlucky? It's just as good an argument.
See the RELNOTES that is included with ISC for a series of bug fixes to the protocol. Both the implementation and the protocol design have been changed substantially to avoid issues seen by real-live people in the field.
Good. That's to be expected and a good thing.
Yes. A few quick tests demonstrated that failure. See earlier messages in this thread.
Nope - "tests" do not show a theoretical failure. Careful argument shows theoretical failure. Tests can only show a failure in an implementation that *may indicate* a theoretical failure. I'd really like to see the discussion of a theoretical failure (i.e., a case where failure must occur if the protocol is implemented correctly). I'm not stating this as some sort of challenge, I genuinely would like to see that discussion.
That doesn't inspire confidence. It's not just a bug, which even FreeRADIUS has had from time to time. The entire design of the protocol has mutated and changed based on discovery of something they missed... YEARS after the protocol was implemented. See also the massive changes in the protocol between 3.0 and 3.1.
Um - that's normal. For any protocol! It's good.
i.e. ISC claims to implement the protocol. If its performance is so much worse than Nomimum, then either (a), ISC didn't implement the protocol as spec'd, or (b) Nominum didn't.
Hm. Or Nominum implemented it better...
I really don't know. I'm happy to say that both the protocol and the implementation are "less than optimal".
Oh, we're in full agreement there.
I'm sure that they developed their own standard for communication between Nominum servers.
Watching it happen suggests very strongly that they are following the standard (such as it is) or something very similar. Whatever: Go for it, and I look forward to the new FreeDHCP server :-) Regards, K. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Karl Auer (kauer@biplane.com.au) +61-2-64957160 (h) http://www.biplane.com.au/~kauer/ +61-428-957160 (mob) GPG fingerprint: 07F3 1DF9 9D45 8BCD 7DD5 00CE 4A44 6A03 F43A 7DEF
