perfSONAR User Q&A and Other Discussion

[Amit <>]

Hi Jason,

I tried it but didn't helped me. 
I just peered servers inbetween for workaround.

Subject: Re: [perfsonar-user] Now BWCTL issue....

Amit;

I see two problems: 

1) You have selected 4 servers that are located in the United states, and
the latency between you and they will be challenging for the NTP algorithms
to use for time keeping.  

2) your servers are 10 seconds off from true time (your output from ntpdate
below suggests this)

With regards to the first issue, reconsider what servers are loaded in your
/etc/ntp.conf file.  For example, we know of some servers located in Japan
and Tawain that may be closer latency wise to you:

> ns.twgrid.org
> 140.109.7.5
> ns2.jp.apan.net
> clock.nc.fukuoka-u.ac.jp
> ntp.nict.jp

Failing this, you can look at the public list of servers from the NTP
project (note that we don't maintain this. and I can't vouch for how
accurate it may be):

http://support.ntp.org/bin/view/Servers/StratumTwoTimeServers

Consider loading in 3-4 other servers (instead of the 4 from the US that you
have now) from India or other close geographical locations.  This will give
NTP a better chance of working.  

With regards to the 2nd issue, the algorithms in NTPD will try to eliminate
'false tickers'.  I do not remember the specifics, but it may be the case
that if clocks appear to be seconds off, they will not be polled anymore for
consideration and may fall into the state that you listed in the output from
NTPQ.  I would suggest the following to test this out:

1) Stop ntpd (sudo /etc/init.d/ntpd stop)

2) Configure 3-4 new servers from the first part above, remove the US based
servers

3) Run this command (sudo ntpd -qgd).  Note that ntpdate is depreciated, and
this command will force a time jump on your local clock based on the clocks
that are loaded in /etc/ntp.conf file.  The output will also be useful for
debugging what is going on with the daemon:

4) If you see that the clock has skipped 10 seconds, restart the daemon
(sudo /etc/init.d/ntpd start)

Good luck;
