Below is how to enabling Network Time Protocol Daemon (ntpd) on your linux box (RedHat, CentOS, Fedora)
Make sure you already install ntp package, if not type
CODE:
# yum install ntp
# yum install ntp
Connecting your linux box to NTP Server. because I am in Indonesia, I am using ntp.kim.lipi.go.id
CODE:
# vi /etc/ntp.conf
server ntp.kim.lipi.go.id
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
# vi /etc/ntp.conf
server ntp.kim.lipi.go.id
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
If you want to provide other PCs in your network synchronize their time on to NTP Server add this line, so other PCs dont need consume bandwidth.
CODE:
# vi /etc/ntp.conf
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
# vi /etc/ntp.conf
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
