我必须从源代码构建ntp
个软件包,并在某些主机上安装所有软件包。安装后,ntpdate 1.us.pool.ntp.org
适用于同步。但是,当我尝试ntpdate <ip_add_of_another_host>
时,它会向我显示以下错误
21 Jul 18:57:53 ntpdate [18287]:没有适合同步的服务器
更奇怪的是,在我尝试ntpdate <ip_addr_of_another_host>
ntpdate 1.us.pool.ntp.org
会有效
我的ntp服务器的配置文件:
# /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/

# 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.

当我执行apt-get install ntp
时,我也尝试了默认配置,但它也不能正常工作。

您可以尝试ntpdate -buv 1.us.pool.ntp.org
-b 适用于您的机器超过1000秒的同步
-u 使ntpdate使用非特权端口
-v 是为了冗长。
我系统的响应更改为同一错误:
没有适合发现同步的服务器
进入:

即使我们面临这个问题......但我们设法通过点击此命令来解决它:
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)。

当您尝试获取时间的服务器没有与上游NTP服务器的连接时,则不适合同步。
