Re: ntpdate[5498]: no server suitable for synchronization found

I assume you are in Asia.  If so, run the following script and  
examine the output.  Pick three hosts that look best and use them in  
place of "3.asia.pool.ntp.org".

Script:

--------cut here---------------
for i in 0 1 2 3
do
	host $i.asia.pool.ntp.org
done | while read x
	echo ""
	do y="$(echo $x | sed 's/^.*has address //')"
	ping -c10 -q $y
	host $y
done
--------cut here---------------

Criteria for a "good" host:

no more than 10% packet loss.
max round trip time is acceptably low
deviation (mdev or stddev, depending on which version of ping) of  
round trip time is acceptably low.

Enjoy!
