Avamar install pauses waiting for NTP

Hi,

I’m currently deploying an Avamar Gen4T.

EMC are upgrading the Avamar code to 7.3.1, during the install it attempts to connect to the NTP servers but times out.

Running asktime on the Utility node, it also times out.

Running the following command /usr/sbin/ntpdate -d xx.xx.xx.xx

It connects to the NTP server.

root@something:~/#: /usr/sbin/ntpdate -d xx.xx.xx.xx

23 Jun 09:35:43 ntpdate[2730]: ntpdate 4.2.8p8@1.3265-o Mon Jun 6 12:31:21 UTC 2016 (1)

Looking for host xx.xx.xx.xx and service ntp

xx.xx.xx.xx reversed to xx.xx.xxcom

host found : xx.xx.xx.com

23 Jun 09:35:50 ntpdate[2730]: adjust time server xx.xx.xx.xx offset 0.021127 sec

If I update the NTP.conf file to have the following line

“restrict -4 default ignore”

rather than

“restrict default ignore”

It works, so is there a bug in the version of NTP code that is currently being run which is ntp-4.2.8p8-47.3

Avamar server version

SUSE Linux Enterprise Server 11 (x86_64)

VERSION = 11

PATCHLEVEL = 3

Regards

Stuart

Update:- I’ve found this technote which explains the problem I’m having https://emcservice.force.com/CustomersPartners/kA2j0000000RFHxCAO
