不使用Raspberry Pi的ntp客户端

Question

免责声明:我不太擅长Linux，我主要是一个Windows管理员。

所以我在我的网络上部署了一堆Raspberry，而我面临的问题之一是它们无法保持正确的时间和日期。因此，我想我只需要安装NTP服务，并将它们指向我的Windows域控制器，它也可以作为NTP服务器工作。但似乎不起作用。这是我的ntp.conf文件：

# /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/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable


# You do need to talk to an NTP server or two (or three).


# 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 192.168.1.11
#pool 0.debian.pool.ntp.org iburst
#pool 1.debian.pool.ntp.org iburst
#pool 2.debian.pool.ntp.org iburst
#pool 3.debian.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
#broadcastclient

其中，192.168.1.11是我的DC/NTP服务器的IP。我的配置有问题吗？顺便说一句，当我使用命令强制更新时：

ntpdate -u 192.168.1.11

起作用了..。但它不能持续下去。当我给树莓断电大约一个小时并重新启动它时，他又在错误的时间.NTP同步不起作用。

编辑:根据请求，下面是ntpq -npcrv命令的输出：

您的NTP源正在使用它自己的本地时钟，这是一个糟糕的时间来源，NTP认为它太远了，无法同步。再次检查/etc/default/ntp是否在NTPD_OPTS中包含-g (通常，该文件将是单行NTPD_OPTS='-g')，并更改192.168.1.11上的NTP配置以使用适当的外部时间源列表(如NTP池)。
