我必须ntp从源代码构建软件包并将它们全部安装在某些主机上。安装后,ntpdate 1.us.pool.ntp.org进行同步。但是,当我尝试这样做时ntpdate <ip_add_of_another_host>,会显示以下错误

7 月 21 日 18:57:53 ntpdate[18287]:找不到适合同步的服务器

更奇怪的是,有时ntpdate <ip_addr_of_another_host>在我尝试后会起作用ntpdate 1.us.pool.ntp.org

我的ntp服务器配置文件:

# /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

# 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
restrict -6 default kod notrap nomodify nopeer noquery

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

当我这样做时,我也尝试了默认配置apt-get install ntp,但它也不起作用。

你可以试试ntpdate -buv 1.us.pool.ntp.org

-b用于当您的机器不同步超过 1000 秒时

-u使 ntpdate 使用非特权端口

-v用于冗长。

我的系统上的响应从相同的错误中改变:

找不到适合同步的服务器

当您尝试从中获取时间的服务器与上游 NTP 服务器没有连接时,则它不适合同步。

即使我们也面临这个问题......但我们设法通过点击这个命令来解决它:

ssh localhost "sudo apt-get install ntp ntpdate ; sudo service ntp stop; sudo ntpdate 0.ubuntu.pool.ntp.org; sudo service ntp start"

为此,您需要安装openssh-server

此外,在触发上述“ssh”命令之前删除 ntp 和 ntpdate (sudo apt-get remove --purge ntp ntpdate) 。
