Solution 2100232.1 : Diameter Signaling Router (DSR), /var/log/messages full of Ntpd_intres[xxxxx]: Host Name Not Found: Ntppeer Errors

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 5.1 and later
Information in this document applies to any platform.

Goal

Stop the below logs from being repeated in /var/log/messages:

ntpd_intres[xxxxx]: host name not found: ntppeerA
ntpd_intres[xxxxx]: host name not found: ntppeerB

Solution

There are couple solutions to this one:

Add an entry in /etc/hosts for the hosts “ntppeerA” and “ntppeerB”, as in
x.x.x.x ntppeerA
x.x.x.y ntppeerB
Modify the entries in /etc/ntp.conf to either IP addresses, or names that do resolve with DNS
For example, in /etc/ntp.conf

peer ntppeerA iburst
peer ntppeerB iburst
can be changed to something like:

peer 10.1.9.2 iburst
peer my.ntpserver.com iburst
(just use valid IP addresses and/or DNS names for the NTP servers being used)
Have the customer add CNAMES to their DNS servers for “ntppeerA” and “ntppeerB”
