Has anybody got ntp running on a SGI. We're running IRIX 3.3.2 on a SGI 4D/340S. It compiled quite nicely, but when running the following messages appeared in SYSLOG: Mar 9 04:19:12 kauri ntpd[5476]: ./ntpd version $Revision: 3.4.1.9 $ Mar 9 04:19:12 kauri ntpd[5476]: patchlevel 13 Mar 9 04:19:12 kauri ntpd[5476]: init_ntp: bad drift compensation value Mar 9 04:19:12 kauri ntpd[5476]: Unknown kernal var _tickadj Mar 9 04:19:12 kauri ntpd[5476]: Unknown kernal var _hz Mar 9 04:19:12 kauri ntpd[5476]: Unknown kernal var _tick Mar 9 04:19:12 kauri ntpd[5476]: sys.precision set to -6 from sys clock of 0 HZ So, has anybody figured out what kernel variables to use? (or any other approach to getting it working.) In frustration I've set up timeslave, but I'd much rather be using NTP. Thanks in advance...

Well, I can't help with ntp, but I have xntpd running on about a half
dozen 4D/xxx machines here at Rutgers. There are some patches
necessary to make it work right. I will be posting them here soon
unless somebody e-mails me with a better place to send them to. With
my patches, xntpd runs quite well and the SGIs keep much better time
than the flock of Suns sitting next to them on the same net.
Enjoy!
Rick

I hacked up ntpd on the on our iri to accept the "tickadj" var, multiply by 1000 and use it to set timetrim via the syssgi() function and SGI_SETTIMETRIM (there is also a SGI_GETTIMETRIM). Tickadj is in uS/S, timetrim is in nS/S. I've been using a value of about -400000 nS/S (so tickadj = -400) for our 4D/20's and a 25: the logical clock stays synced with that. timetrim is a signed long. Check babar.mmwb.ucsf.edu [128.218.21.42] in ~ftp/pub/ntpd.patch for the patch and the Makefile. - Scott Presnell (srp@cgl.ucsf.edu) -- Scott Presnell +1 (415) 476-9890 Pharm.
