I mean the NTP server is misconfigured. Check its ntp.conf!

What should I change in the ntp.conf of the NTP server to make it work?!

Again, this is my ntp.conf file's contain:

restrict mask nomodify notrap

That looks okay.
Add an unrestricted access from localhost

restart ntpd, and after a minute check with
ntpq -np

Now I got this when I implemented ntpq -np:
No association ID's returned

And I added already

When I try from other linux client #ntpdate its return with
20 Sep 11:59:07 ntpdate[5015]: no server suitable for synchronization found


---------- Post updated at 05:51 AM ---------- Previous update was at 05:28 AM ----------

And when I change the:



It gives me the following when I execute ntpq -np:

[root@host1 ~]# ntpq -np
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================       .INIT.          16 l    -   64    0    0.000    0.000   0.000

I'm sort of lost now!

Any ntp messages in /var/log/messages?
Is this a virtual system (instance on vmware, xen, virtual box)? Then the HW clock is problematic.

Yes sir! The NTP server is running on VMware! and the other clients is on VMware too. Is that the reason behind this issue? and if its, what is the solution for such cases.

Yes I think this is your problem.
Unfortunately I don't know if there is possibility to have a VMware guest act as an NTP server.
Google for: ntp server on vmware guest
The safest metod is to use another server with real hardware.
The VMware ESX server itself can act as an NTP server.
