The current "era" started at the stroke of 10 1.1.1.2.6.1 tls midnight on 1 Jan 1900, and ends just before the stroke of midnight on 11 1.1.1.2.6.1 tls 1 Jan 2036. 12 1.1.1.2.6.1 tls In the past, we have used the "midpoint" of the range to decide which 13 1.1.1.2.6.1 tls era we were in. Given the longevity of some products, it became clear 14 1.1.1.2.6.1 tls that it would be more functional to "look back" less, and "look forward" 15 1.1.1.2.6.1 tls more. We now compile a timestamp into the ntpd executable and when we 16 1.1.1.2.6.1 tls get a timestamp we us the "built-on" to tell us what era we are in. 17 1.1.1.2.6.1 tls This check "looks back" 10 years, and "looks forward" 126 years. 18 1.1.1.2.6.1 tls 19 1.1.1.2.6.1 tls So if you have a system that ... 20 1.1.1.2.6.1 tls 21 1.1.1.2.6.1 tls * ntpdc responses disabled by default 22 1.1.1.2.6.1 tls 23 1.1.1.2.6.1 tls Dave Hart writes: 24 1.1.1.2.6.1 tls 25 1.1.1.2.6.1 tls For a long time, ntpq and its mostly text-based mode 6 (control) 26 1.1.1.2.6.1 tls protocol have been preferred over ntpdc and its mode 7 (private 27 1.1.1.2.6.1 tls request) protocol for runtime queries and configuration. There has 28 1.1.1.2.6.1 tls been a goal of deprecating ntpdc, previously held back by numerous 29 1.1.1.2.6.1 tls capabilities exposed by ntpdc with no ntpq equivalent. I have been 30 1.1.1.2.6.1 tls adding commands to ntpq to cover these cases, and I believe I've 31 1.1.1.2.6.1 tls covered them all, though I've not compared command-by-command 32 1.1.1.2.6.1 tls recently. 33 1.1.1.2.6.1 tls 34 1.1.1.2.6.1 tls As I've said previously, the binary mode 7 protocol involves a lot of 35 1.1.1.2.6.1 tls hand-rolled structure layout and byte-swapping code in both ntpd and 36 1.1.1.2.6.1 tls ntpdc which is hard to get right. As ntpd grows and changes, the 37 1.1.1.2.6.1 tls changes are difficult to expose via ntpdc while maintaining forward 38 1.1.1.2.6.1 tls and backward compatibility between ntpdc and ntpd. In contrast, 39 1.1.1.2.6.1 tls ntpq's text-based, label=value approach involves more code reuse and 40 1.1.1.2.6.1 tls allows compatible changes without extra work in most cases. 41 1.1.1.2.6.1 tls 42 1.1.1.2.6.1 tls Mode 7 has always been defined as vendor/implementation-specific while 43 1.1.1.2.6.1 tls mode 6 is described in RFC 1305 and intended to be open to interop 44 1.1.1.2.6.1 tls with other implementations. There is an early draft of an updated 45 1.1.1.2.6.1 tls mode 6 description that likely will join the other NTPv4 RFCs 46 1.1.1.2.6.1 tls eventually. (http://tools.ietf.org/html/draft-odonoghue-ntpv4-control-01) 47 1.1.1.2.6.1 tls 48 1.1.1.2.6.1 tls For these reasons, ntpd 4.2.7p230 by default disables processing of 49 1.1.1.2.6.1 tls ntpdc queries, reducing ntpd's attack surface and functionally 50 1.1.1.2.6.1 tls deprecating ntpdc. If you are in the habit of using ntpdc for certain 51 1.1.1.2.6.1 tls operations, please try the ntpq equivalent. If there's no equivalent, 52 1.1.1.2.6.1 tls please open a bug report at http://bugs.ntp.org./ 53 1.1.1.2.6.1 tls 54 1.1.1.2 kardel --- 55 1.1.1.2 kardel NTP 4.2.6p5 (Harlan Stenn <stenn (a] ntp.org>,
