perfSONAR User Q&A and Other Discussion

["Lixin Liu" <>]

Hi Jason,

Thanks for your information.

I rebooted two hosts (in University of Saskatoon) and they are now
showing up in the list of Global Services.

I still have issue with two other hosts (in University of Manitoba).
I followed your suggestion. It has been more than two hours, but I
still do not see this host in the list. However, there was a network
(BGP) problem early today that may affect the registration.

Here is the log file (hostname bdw-umanitoba.westgrid.ca).

The NTP server on the host you mentioned was changed by the local admin
to use local NTP servers, but there are only two servers in the config.
I added two more and should be fine now.

Thanks,

Lixin.
