NTP client configuration on Linux - RHEL 6.


1. First you got to install the NTP package. I suggest you try using YUM for this task:
# yum install ntp
2. Then you want to have the NTP service started at boot time:
# chkconfig --levels 235 ntpd on
3. Specify the NTP server you’ll be synchronizing with. I suggest you use the NTP server pool from ntp.org:
if the system is connected to internet. Otherwise use your ntp server in the company network.
# ntpdate 0.pool.ntp.org
4. Start the NTP service:
# service ntpd start
********************************************************

Configure ntp client in a machine.

vi /etc/ntp.conf

#server 127.x.x.1
#fudge
server 10.1.0.34

wq!

ntpdate 10.1.0.34
service ntpd start
chkconfig ntpd on
chkconfig --list ntpd

To view the status of time synching with the ntp server. 
ntpq -pn
ntpstat
