I have a box running ubuntu 10.04 x86 & it's isolated by necessity from a lot of the network. It is blocked from DNS.
I'd like it to keep accurate time, so I've configured NTP with several servers, all IP addresses. It's got the IP address, so it won't need to do DNS lookups, riiiight?
Here's the error I get when I try to update time:
date before sync:
Fri May 20 08:03:32 PDT 2016 * Stopping NTP server ntpd ...done. Name server cannot be used, exiting20 May 08:03:32 ntpdate: name server cannot be used, reason: Temporary failure in name resolution * Starting NTP server ntpd ...done. COMMAND FAILED: /usr/sbin/ntpdate -u 22.214.171.124 prefer #S2Platform-Server1 126.96.36.199 prefer #S2Platform-Server2 188.8.131.52 prefer #S2Platform-Server3 date after sync: Fri May 20 08:03:32 PDT 2016 Sync failed
My question: is this ever going to work or does NTP just flat-out require DNS? I've done a lot of googling but I can't find any info about this.
I've also asked this question on the forums.
