I've gotten off the net a version xntp for the Sun and it seems to be a lot more than I need. All I want to do is sync time on about 15 nodes. The time doesn't have to be very accurate, all the nodes just need to be within a second or so. Is there a time server (such as ntp) which will allow me to run the server on a node I specify and then have up to 15 clients? Is it available for the HP9000/3xx running HP-UX 7.0? Any help is appreciated... -- Jeff Dalton, ESL Inc. Real programmers can write jsd@esl.com Fortran in any language.

What I do here is run xntpd on a few select machines, then the rest of them
sync off those by using ntpdate run from cron every few hours.ken@HPSDLZ.SDD.HP.COM (Ken Stone) (01/05/91)

What I do here is run xntpd on a few select machines, then the rest of them sync off those by using ntpdate run from cron every few hours. The NTP protocol and the UNIX daemon's clock adjustment strategy are very economically designed, to accomplish the task with a minimum of intrusion. The memory and CPU cost of running xntpd on a workstation is remarkably low, since it is fairly small and only schedules itself when it knows it will really be needed. The overhead of a local networkful of workstations chiming with each other is also remarkably low, and will disappear into the background noise on your wire. Don't be afraid to run the daemon everywhere.
