没有适合同步的服务器对于NTP服务

Question

我必须ntp从源代码构建软件包并在一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,当我尝试这样做时,ntpdate <ip_add_of_another_host>它向我显示以下错误

21 Jul 18:57:53 ntpdate [18287]:没有适合同步的服务器

更奇怪的是,有时ntpdate <ip_addr_of_another_host>在我尝试之后会有效ntpdate 1.us.pool.ntp.org

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

# 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 ::

我也尝试过默认配置apt-get install ntp,但它也不能正常工作.

Answer 1

你可以试试 ntpdate -buv 1.us.pool.ntp.org

-b适用于机器不同步超过1000秒的情况

-u使ntpdate使用非特权端口

-v是为了冗长.

我的系统的响应从同一错误改变:
