- Hi everyone,
-
- I would like to use xntpd for time synchronization on several labs of
- SGI Indigos. There are a total of 115 machines. I have built and
- tested xntpd successfully, but it doesn't include kernel support for
- setting tickadj on the Indigo. I have tried tweaking tickadj by hand,
- but no matter what I do it generates large volumes of syslog messages
- saying that it is stepping the clock backwards (one every couple of
- minutes).
-
- I also considered running ntpdate periodically from cron to sync the
- clock, either with our stratum-2 servers or with other various
- stratum-3 machines around campus. This worked well for keeping the
- time in sync. However, it turned out to be a major hassle trying to
- set things up in such a way that no host got bombarded with ntp
- requests.
-
- So, my basic question is: has anyone gotten xntpd to work well on an
- Indigo? If so, how did you do it?
-
- In case it's important, most of our stratum-3 servers are DECstations
- running version 1 ntpd. This is mainly because DECs seem to have
- reasonably good clocks, and ntpd is included with Ultrix.
-
- Any help would be appreciated!
- Paul
