NS120: problems with NTP
Like the title says. As a very first step I tried to Stop, delete and re-add the NTP servers however I always see "Running, Disconnected". To be honest it would be kind of strange to see "Running, Connected" since NTP is over UDP but that being said, "Running, Disconnected" doesn't seem right either. I've already spoken with my network team and they confirmed UDP port 123 is open all the way between the storage and the NTP server. Furthermore, I have another server on the same subnet which can successfully reach the NTP server and get corrections. Stats look like this:
[nasadmin@NS120-1-CS1 ~]$ server_date ALL timesvc stats ntp
server_2 :
Time synchronization statistics since start:
hits= 0, misses= 0, first poll hit= 0, miss= 41
Last offset: 0 secs, 0 usecs
Current State: Running, disconnected, interval= 60
Time sync hosts:
XX.XX.XX.XX,
server_3 :
Time synchronization statistics since start:
hits= 0, misses= 0, first poll hit= 0, miss= 0
Last offset: 0 secs, 0 usecs
Current State: Running, disconnected, interval= 60
Time sync hosts:
XX,XX,XX,XX
I ran
tcpdump -i eth3 -nnv udp and port 123
in a screen'd session and went through the stop/delete/start routine again and I didn't see any outbound UDP traffic. TIA.
