没有适合同步的服务器对于NTP服务

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>

后,有时候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/

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
# Specify one or more NTP servers.

# Use servers from the NTP Pool Project. Approved by Ubuntu Technical Board
# on 2011-02-08 (LP: #104525). See http://www.pool.ntp.org/join.html for
# more information.
server 127.1.1.0 # local clock
fudge 127.1.1.0 stratum 10
# 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:

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。
