Re: NTP Server Configuration
If this RHAS machine does not have an Internet presence always, use chrony to sync with an external time source atleast intermittently via dial-up. The use of the "ntp" package is not recommended; "ntpdate" is deprecated now and the "ntp" package contains the "ntp-server" component.

Re: NTP Server Configuration
Comment the following lines:
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
Ensure that you have this line:
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
In the hosts that will be client of your NTP server:
server x.y.z.p
Where x.y.z.p is the IP of your local ntp server just configured.
You should have more than one local ntp server. These servers should synchronize with an external source and also should bee peers.

for ntp server
ip=172.22.36.110 hostname=ABC_UDB01
for client ntp servers
ip=172.22.36.112 hostname=ABC_UDB02
ip=172.22.36.114 hostname=ABC_UAPP01

Re: NTP Server Configuration
You choose one of the machines to connect to the outside world, see that it can actually sync to an outside server with the ntpq -p command. In this case the outside world should be a time server designated by your network admin. If no such machine is available then pick the system with the most accurate system lock.
Then you modify the ntp.conf files on of the other systems to point to the designated server.
chkconfig ntpd (or xntpd) on
service ntpd start
ntpq -p to check syncing is happening.
It is not possible to time sync if the servers time is too far off reality so a manual adjustment with the date command may be called for.

Re: NTP Server Configuration
Issue:
How do I set up a Network Time Protocol (NTP) Server on a LAN with no Internet access?
Resolution:
On the system that will be the NTP server, add the following lines in /etc/ntpd.conf file:
Under --- CLIENT NETWORK --- add:
restrict
Under --- GENERAL CONFIGURATION --- edit the line:
fudge 127.127.1.0 stratum 10
to read:
fudge 127.127.1.0 stratum 3
This will present the internal clock as a stratum 3 clock to NTP clients. The clients will now sync to the NTP server, assuming their own internal clocks are left at stratum 10.
---------------------
so i want to know that it will resolve the issue as if i use stratum 3 instead of stratum 10 as my local ntp server is not syncing when i use to start the service is showing syncing fialed...kindly help me out in this regards

Re: NTP Server Configuration
To ensure if your server is starting ntp with internal clock, use the following command:
ntpq -pn
You should see an output like this:
*127.127.1.0 127.127.1.0 12 l 19 64 377 0.000 0.000 0.977
If you see the "*" symbol, then you are using that server as the NTP server, in this case, your local clock. If you see blank then you are not syncing your server.
