- -> I'm trying to run the latest release of xntp v3 on an SGI Indigo running
- -> v4.0.1 of the OS. xntpd is having trouble keeping the clock in sync,
- -> generating lots of STEP adjustments in the syslog file. Since the
- -> SGI build uses -DNOKMEM, it's using the built-in values for tick and
- -> tickadj. I'm assuming these are wrong for the SGI Indigo and that
- -> is what is causing the problem. Does anyone have a good idea for
- -> tick and tickadj values for Indigos?
- ->
- -> It might be nice to have tick and tickadj settable via the Makefile,
- -> say maybe -DTICK=xx and -DTICKADJ=xx, so that building xntp forsystems
- -> that need -DNOKMEM would be easier. I noticed that there are special
- -> cases in the code for the RS6000. If someone can give me some good values
- -> for tick and tickadj for the SGI, I can work up the changes to the
- -> code to make -DTICK and -DTICKADJ work, with the current defaults if
- -> -DTICK and -DTICKADJ are not set.

- I think it must be a specific problem of the INDIGO. The latest version of
- xntp3 runs on our SGI 4D/220 (IRIX4.0.1) very stable and I have seen no steps
- during the last two weeks (try ntpq -p redfield.ethz.ch). I saw similar
- problems on IBM/RS6000 when tickadj was too small. That is the reason why I
- hard coded the value of 1000 for tickadj on the RS6000 in the code. Try
- setting a larger value of tickadj and check whether xntpd3 is then able
- to sync to the other machine.
- I think its a good idea to be able to set tick and tickadj in the Configfile
- but we need a volunteer to do this :-).
