[ntp:questions] ntpd server on Linux/Debian with SPARC Sun Blade 100


Fri Sep 1 15:26:16 UTC 2006


Hello all,

I'm trying to setup a server on a Linux/Debian system. The hardware is a
Sun Blade 100. It's running the stable distribution of Debian, but with
a 2.6.16 kernel (and some few libs from testing).

The goal is to offer it in the pool.ntp.org as ntpd server.

So, I have choose 5 Swiss server to synchronize with (stratum 2). Here
is the ntpq -p output:

       remote           refid      st t when poll reach   delay   offset  jitter

The ntpdc -c peers give me:

       remote           local      st poll reach  delay   offset    disp
  =======================================================================

What is strange is the the offset seems to me a little bit too high. I
have compared this to my own Debian/x86 system. In this case, the offset
is more close to 0.001 (almost 100 times smaller).

Has someone an idea why this is so bad ? Is the Debian/SPARC64 a problem ?
Is the Blade 100 hardware the problem ? I don't really know where to
search. I already have upgraded the kernel from a 2.4 to a 2.6.

ntp sersion is ntp-server 1:4.2.0a+stable-2sarge1 from Debian stable.

Thanks in advance for any tips.
