| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ntp leap-leapseconds support. r289421: Add default leap-seconds file. This should help ntp networks get the leap second date correct Updates to the file can be obtained from ftp://time.nist.gov/pub/ or ftp://tycho.usno.navy.mil/pub/ntp/. r293037: Update leap-seconds to latest. This will satisfy the ntpd leap-second version check. r294773: Add support for automatic leap-second file updates. The working copy of leapfile resides in /var/dbntpd.leap-seconds.list. /etc/ntp/leap-seconds (periodically updated from ftp://time.nist.gov/pub/ or ftp://tycho.usno.navy.mil/pub/ntp/) contains the master copy should automatic leapfile updates be disabled (default). Automatic leapfile updates are fetched from $ntp_leapfile_sources, defaulting to https://www.ietf.org/timezones/data/leap-seconds.list, within $ntp_leapfile_expiry_days (default 30 days) from leap-seconds file expiry. Automatic updates can be enabled by setting $daily_ntpd_leapfile_enable="YES" in periodic.conf. To avoid congesting the ntp leapfile source the automatic update randomized by default but can be disabled through daily_ntpd_avoid_congestion="NO" in periodic.conf. r294884: Allow specification of fetch options for ntp leap-seconds fetch.

| | | | | Tighten default restrictions for ntpd(8) server and provide a link to NTP access restriction documentation.
* As of r232844 we no longer need the maxpoll 9 workaround.delphij2012-08-201-8/+7

* 1) Use our vendor domain at the pool.dwmalone2009-07-131-11/+16
| | | | | | | | | | | | 2) Point people at the pool website and encourage people to provide a server in the pool (as a courtesy to the pool guys). 3) Fix a spelling. 4) Comment out the local clock and include a link to documentation for use of the local clock on the ntp.org site.

* Welcome to a default installed /etc/ntp.confedwin2009-06-071-0/+59
This NTP configuration file points to the [012].pool.ntp.org servers, which will return a list of geographical local NTP servers. It uses the best-practice options of "iburst" and "maxpoll 9". It gives examples on how to use the "restrict" commands, which are unfortunately not working when you use the pool.ntp.org servers. It sets up a fudge server so any clients syncing against this server will always be synced even if we lose the master. The idea of this file was briefly discussed on -net.
