ESXi时间同步测试_与Windows搭建的NTP_server无法同步的原因

3.配置ESXi的NTP服务器地址

4.监控数据包

只有从ESXi发出的NTP包，NTP server没有回复。

5.在KB的基础上做调整，修改注册表，启动NTP服务

修改注册表的键值:Run->regedit

HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\W32Time

\\TimeProviders\\NtpServer内的Enabled为1，打开NTP服务器功能（默认是不开启NTP Server服务

重启W23Time服务

6.启动NTP服务后，抓包显示NTP服务器有了回复

7.NTP数据包

ESXi发出的NTP请求包是NTP版本4.

Windows搭建的NTP Server的响应包是NTP版本3

ESXi未完成时间同步，NTP服务器发回的响应包并未被接受。

测试ESXi使用Linux搭建NTP的服务器

1.配置Linux作为NTP服务器

1.编辑ntp.conf

2.Ntp.conf配置示例： # Permit time synchronization with our time source, but do not # permit the source to query or modify the service on this system. restrict default nomodify # Permit all access over the loopback interface. This could # be tightened as well, but to do so would effect some of # the administrative functions. restrict 127.0.0.1 9 / 13

# -- CLIENT NETWORK ------- # Permit systems on this network to synchronize with this # time service. Do not permit those systems to modify the # configuration of this service. Also, do not use those # systems as peers for synchronization. # restrict 192.168.1.0 mask 255.255.255.0 nomodifynotrap # --- OUR TIMESERVERS ----- server 0.pool.ntp.org server 1.pool.ntp.org server 2.pool.ntp.org # --- NTP MULTICASTCLIENT --- #multicastclient # listen on default 224.0.1.1 # restrict 224.0.1.1 mask 255.255.255.255 nomodifynotrap # restrict 192.168.1.0 mask 255.255.255.0 nomodifynotrap # --- GENERAL CONFIGURATION --- # # Undisciplined Local Clock. This is a fake driver intended for backup # and when no outside source of synchronized time is available. The # default stratum is usually 3, but in this case we elect to use stratum # 0. Since the server line does not have the prefer keyword, this driver # is never used for synchronization, unless no other other # synchronization source is available. In case the local host is # controlled by some external source, such as an external oscillator or # another protocol, the prefer keyword would cause the local host to # disregard all other synchronization sources, unless the kernel # modifications are in use and declare an unsynchronized condition. # server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 # # Drift file. Put this in a directory which the daemon can write to. # No symbolic links allowed, either, since the daemon updates the file # by creating a temporary in the same directory and then rename()'ing # it to the file. # driftfile /var/lib/ntp/drift 10 / 13
