perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <>]

Hi all,

 

I have found my problem, it was in the srcnode directive of /etc/owampd/owampd.conf.  Since I swapped the servers, I need to update address there, I only enable owamp on one interface.

 

Thank you all and have a great new year’s holiday!

I also saw these in the log file:

Hi all,

 

On one of our perfsonar boxes, the owampd keeps dying.  I got error messages initially, when I try to start it:

 

owampd[4923]: FILE=time.c, LINE=112, NTP: Status UNSYNC (clock offset issues likely)

owampd[4923]: FILE=time.c, LINE=118, NTP: STA_NANO should be set. Make sure ntpd is running, and your NTP configuration is good.

/etc/init.d/owampd start: owampd started

 

Owampd would die right away.  The ntp is running on the server:

+saturn.es.net   .CDMA.           1 u   50   64    3    4.683    1.631   0.211

 

Do I have to wait for bit until the ntp is “stable”?  I just rebooted the server a short while ago (actually, I swapped the identities of two perfsonar boxes this morning).

 

I would appreciate ideas to correct the issue here.  Thank you.
