Сложности с синхронизацией по NTP

Nyancat · 20 ноября 2017, 15:45:10

Здравствуйте.
Пытаюсь уже длительное время настроить ntpdate.
Собственно несколько недель назад установил

apt-get install ntp ntpdate
И вот вроде по всем инструкциям всё максимально просто, но в результате не могу убедиться, нормально ли оно работает.
ntp.conf:

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /var/lib/ntp/ntp.drift

# Enable this if you want statistics to be logged.
statsdir /var/log/ntpstats/

logfile /var/log/ntp.log

filegen clockstats file clockstats type day enable

# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example

# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will
# pick a different set every time it starts up. Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>

server 0.ru.pool.ntp.org iburst
server 1.ru.pool.ntp.org iburst
server 2.ru.pool.ntp.org iburst
server 3.ru.pool.ntp.org iburst

# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details. The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery limited
restrict -6 default kod notrap nomodify nopeer noquery limited

# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1

# Needed for adding pool entries
restrict source notrap nomodify noquery

# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust

# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
#broadcast 192.168.123.255

# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines. Please do this only if you trust everybody on the network!
#disable auth

Вот всё бы ок, но только нигде на сервере я не прописывал гугловский ntp сервер, а в конфиге прописаны только:

server 0.ru.pool.ntp.org iburst
server 1.ru.pool.ntp.org iburst
server 2.ru.pool.ntp.org iburst

Почему же он показывает только один сервер гугла, вместо четырёх перечисленных?

Время то вроде правильное на сервере, но всё равно работает всё как-то подозрительно.

Спустя несколько дней вспомнил, что вводил этот адрес ntp сервера в роутер Microtik. Скриншот во вложении. Мб оттуда берёт адрес? О_о

Вопросы:
Почему он не использует адреса из конфига?
Что значат ошибки в конце лога?
Как понять, работает ли автоматическая синхронизация вообще, и будет ли дальше стабильно работать?

ОС Debain 9

Заранее благодарен за ответы.

[offtopic]Впервые столкнулся с проблемой в Debain,
которую не смог решить с помощью гугла

Эти ntp[d|date] очень капризные в настройке были в моё время, то то не того, то того не этого. И с документацией глухо. Гораздо проще настроить systemd-шный встроенный ntp-клиент, или если раздавать надо, openntpd.

Вот конфиг openntpd и сервера для разнообразия:
