I know that everyone who reads my blog (I know of one occasional reader, but meh...) can't wait to hear about my technical work with computers! Right? ... What? Oh... now I'm sad ;). If nothing else, I fantasize about someone running across one of these posts and having it help them with something they're working on. Anyway, I got NTP (Network Time Protocol) working on my server (which is now a Stratum 3 system, which is plenty good for my purposes). All I really needed to do was to add the following entries into my "/etc/ntp.conf" file, and make "/etc/rc.d/rc.ntpd" executable (so it would run if the system was rebooted... I ran it manually to get it going without the need for a reboot):
Spiff.
Next NTP job is to allow the other systems in my house to synchronize to my server (so they will be Stratum 4 devices), but since the latency and jitter in my home LAN is low, they should be pretty tightly coupled to my server's time. I should probably add the "stratum 2" indicators to the configuration file for the NRC servers as well, just to make it explicit (but I don't think it matters much since they're the only servers I list).
P.S. If you're in Canada, the web site is:
http://www.nrc-cnrc.gc.ca/eng/services/time/network_time.html
Most countries presumably have their own time servers... all of them use Universal Coordinated Time (the time zone formerly known as Greenwich Mean Time).
server time.nrc.ca # NRC stratum-2 service primary server server time.chu.nrc.ca # NRC stratum-2 service secondary serverEverything else in the config file (from Slackware 14.1) was able to stay "as was". I now get my time synchronization information directly from the NRC (Canadian National Research Council) Stratum 2 servers. My servers are now within a few milliseconds of the world standard time kept at the NRC using multiple atomic clocks.
