[orbit-user] Local NTP server

[Ivan Seskar]

Hi Fehmi,

To improve scaling we now have two ntp servers in the grid and, just to make sure we can move things around, we introduced CNAMEs ntp1.grid.orbit-lab.org and ntp2.grid.orbit-lab.org for them. Also, ntp servers are advertised by the grid dhcp service so you can use that as well.

Ivan.  

PS: dhcp1 is behind the firewall so large number of nodes accessing it = potential trouble.

Hi Ivan,

Thanks for your answer!
I tried the following:

-----------------
node2-1:~# ntpdate console.grid.orbit-lab.org
 1 Jul 13:08:44 ntpdate[2697]: no server suitable for synchronization found node2-1:~# ntpdate dhcp1a.orbit-lab.org Error : Name or service not known
 1 Jul 13:09:12 ntpdate[2700]: can't find host dhcp1a.orbit-lab.org

 1 Jul 13:09:12 ntpdate[2700]: no servers can be used, exiting
-----------------

Any idea ?

Cheers,
Fehmi
