segmentation fault on ntp

[Kevin K]

Need help with ntp segmentation faults.

• GUI reports: "Reminder: The system time has not been synchronized with an NTP server."
• syslog.log contains many: "reboot_scheduler: [timecheck] NTP sync error"
• Running "ntp -w -p pool.ntp.org" reports: "Segmentation fault"
• Running "ntp -w -p 192.81.135.252" reports "ntp: reply from 192.81.135.252..."
• Running "ntp -w -p go.boom.now" reports "Segmentation fault"

So clearly, ntp doesn't like something about my DNS.

"nslookup pool.ntp.org" reports

Server:    8.8.8.8
Address 1: 8.8.8.8 dns.google
Name:      pool.ntp.org
Address 1: 45.55.58.103 time.walb.tech
Address 2: 204.2.134.163 pacific.latt.net
Address 3: 129.250.35.250 x.ns.gin.ntt.net
Address 4: 50.18.44.198 smtp.brandonenright.net

or, if I enable "Wan: Use local caching DNS server as system resolver (default: No)" it reports

Server:    127.0.0.1
Address 1: 127.0.0.1 localhost.localdomain
Name:      pool.ntp.org
Address 1: 129.250.35.251 y.ns.gin.ntt.net
Address 2: 108.62.122.57 ntp2.radio-sunshine.org
Address 3: 99.104.170.138 99-104-170-138.lightspeed.lsvlky.sbcglobal.net
Address 4: 184.105.182.7 ntp3.junkemailfilter.com

but either way, I get segmentation faults when I run "ntp -w -p pool.ntp.org".

If I configure the GUI with an IP address for a time server, it synchs. Suggestions?

I used IP for a long while, very reliable, unlike my experience using domain names.
Now using Chrony via ntpMerlin, works superbly.

OK...you've stumped my friend 'Carnac the Magnificent'
What router and firmware?

 

[Kevin K]

Fair question.
AC68U and AC1900
Version 384.19

(And I just added those to my signature but, sadly, I haven't figured out how to make my signature show up here.)

Same problem with my router too, Merlin firmware version:386.1, Asus RT-AC88U.

Running "ntp -w -p pool.ntp.org" returns "Segmentation fault"
Running "ntp -w -p 162.159.200.123" returns "ntp: reply from 162.159.200.123: offset...""

Any sustainable solutions other than hardcoding IP address in GUI?
