Open /etc/ntp.conf file and all the bellow lines so that it looks the local NTP server. NTP server Now we needed to allow NTP clients to access the Server, to our network, we allow 192.168.87.0/24 network to synchronize the time over network located in the own environment 192.168.87.150

We needed to add the specific authorization policy to settings restrict 81.6.42.224 mask 255.255.255.245 nomodify notrap noquery The Above will deny all the access to any machine, server or clients. Open the configuration file and add the following lines – restrict default ignore Demo Environment Details 192.167.87.150 Local NTPD server The server then allows the other machines in our network to request the time date. If we have lots of server and desktop machines in the environment and then we should have the NTP server so that all the servers can contact and update the NTP server provided by the ISP or the Public time located at ntp.org. > Package ntpdate.x86_64 0:4.2.4 will be an update > Package ntpdate.x86_64 0:4.2. will be updated > Processing Dependency: ntpdate = 4.2.4 for package: ntp-4.2. entos.4.x86_64 > Package ntp.x86_64 0:4.2.4 will be an update > Package ntp.x86_64 0:4.2. will be updated Loading mirror speeds from cached hostfile The NTP package has ntpdate (Which updates the date and time from the remote machines using the network) and ntpd (A daemon which adjusts the system time). The NTP package have utilities and daemons that will synchronize the machine time to Coordinated Universal Time (UTC) via the NTP protocol. In RHEL / CentOS Linux we can use NTP or OpenNTPD server, which provides client and server software for time synchronization. NPT is used to synchronize a computer’s machine’s time with another time source. This article will help to know how to configure an NTP (Network Time Protocol) server and client on RHEL/Cent OS Linux to manage the system clock with to help of an NTP server.
