How to build an NTP server in CentOS
The Network Time Protocol (NTP) is used to synchronize the system time of different hosts on the network. All Hosts you manage can synchronize their time with a specified
First, build time synchronization server1. Compile and install NTP serverRpm-qa | grep NTPIf not found, the NTP package is not installed, the NTP packet is found on the CD, and theRPM-UVH ntp***.rpmTo install2. Modify the ntp.conf configuration fileVi/etc/ntp.conf①, first co
Today there is a small project, completely self-made, originally thought very simple NTP service, I give toss for 2 hours only to support the head (formerly are operations, not too much attention, so this technology, in simple all need to kiss taste AH), here records for the future do not waste time.
Target environment, 5 Linux CentOS 6.3, one as NTPD service and external public
This paper introduces two kinds of protocols commonly used in time server: SNTP and timing, and explains the setting of Linux Time service in LAN environment, and finally realizes the synchronization and calibration of all computer clocks in the whole LAN environment. 1, what is the network Time service

Takeaway:It's critical that all devices on an organization's network display the accurate time and date. if they don't, things can go wrong in a hurry. david Davis explains why Cisco devices need to use Network Time Protocol (

Problem Description: Due to the implementation of Vcloud, the vcenter domain is required for the IaaS Server server account to gain access to the vcenter hardware resources, the results found in vcenter domain when the host name is not available to join the domain, After you change the vcenter hostname, you still cannot join the domain.Workaround: The test found that the Vcenter host
I. Introduction
Network Time Protocol (NTP) is used to synchronize time between the distributed time server and the client. NTP is transmitted Based on UTP packets. The UDP port used is 123.
# hwclock -systohccn.pool.ntp.org is a public NTP server located in China to synchronize your time (If your time is different from the server's time cut, you may not be able to synchronize time or even execute commands such as su
ServicesNomodify: The client cannot change the time parameters on the server side, but the client can perform the network calibration via the server. Notrust: The client source will be treated as untrusted subnet unless authenticatednoquery: No time query for clients: Client cannot query
When a program runs on multiple servers, the clock on these servers is sometimes the same. However, when the server runs for a certain period of time, the clock on each server may be different, in this case, all servers need to automatically calibrate their respective clocks.
NTP is a convenient clock service, which ca
