Criticism
OpenNTPD has been criticized as being less accurate than the NTP daemon produced by the Network Time Protocol Project. While the OpenNTPD project admits the plausibility of this claim, it claims this as a trade-off between microsecond precision and the benefits of simplicity and security OpenNTPD offers.
OpenNTPD has also been criticised for violating the NTP protocol by omitting correct information on the accuracy of transmitted data: OpenNTPD servers claim to be infinitely accurate (earlier versions claimed to be in stratum 1; while this particular issue has been fixed, OpenNTPD 3.9p1 still serves time with a zero dispersion).
Shortly after the release of OpenNTPD 3.6, Brad Knowles wrote an article entitled OpenNTPd Considered Harmful criticizing various aspects of OpenNTPD, as well as the split development model that the project employs, which is also used in the development of OpenSSH and OpenBGPD. Darren Tucker, the main developer on the portable branch of OpenNTPD, wrote a detailed response to this article, discussing some of the issues addressed in the OpenNTPD 3.6.1 release and branding some of Knowles comments "quite misleading." Knowles' article also prompted the addition of a section to the OpenBSD networking FAQ explaining and rebutting its claims.

Famous quotes containing the word criticism:
“A bad short story or novel or poem leaves one comparatively calm because it does not exist, unless it gets a fake prestige through being mistaken for good work. It is essentially negative, it is something that has not come through. But over bad criticism one has a sense of real calamity.”
—Rebecca West (1892–1983)
“The aim of all commentary on art now should be to make works of art—and, by analogy, our own experience—more, rather than less, real to us. The function of criticism should be to show how it is what it is, even that it is what it is, rather than to show what it means.”
—Susan Sontag (b. 1933)
“I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.”
—Ernest Hemingway (1899–1961)
