here we are using only ntp1 and ntp2 is not in use
while pinging npt1 we foound the following output
ping 132.95.160.58
PING 132.95.160.58 (132.95.160.58) 56(84) bytes of data.
--- 132.95.160.58 ping statistics ---
78 packets transmitted, 0 received, 100% packet loss, time 77379ms
wew found that pinging from my local server to ntp server is inhibited that's why we are getting 100% packet loss .
with the same ntp server we had another local server running fine without problems in ntp server there also we found pinging is inhibited

NAME
dceping - test the ability to contact DCE services from a local DCE client.
SYNOPSIS
dceping [-n number] [-s time] [-v] [-C] [service_name ...] required to specify the literal strings, NAMESPACE or STRING_BINDING (see nond-
cesvc(4)).
OPTIONS
-n number Specify the number of pinging cycles. Each service is tested once per cycle. The default is one pinging cycle. Specifying -n 0
makes pinging continuous.
-s time Specify time, in seconds, to wait between pinging cycles. You must specify more than one pinging cycle with the -n option in
order to use -s.
-v Run in verbose mode.
-C Ping only core DCE services. This option is ineffective if a service_name is specified on the command line.
DESCRIPTION
dceping verifies that a local DCE client can communicate with DCE and other services. It uses the RPC management interface to determine if
the DCE service is listening. The core DCE services that dceping checks include secd, cdsd, gdad, rpcd, cdsadv, dtsd, and sec_clientd.
You can ping other DCE and non-DCE services by naming them in the file, /opt/dcelocal/hpadmin/etc/nondcesvc. If you want to determine at
run time what services you want dceping to ping, you may do so using the same file. See the manpage, nondcesvc(4), for more information.
You may specify the services to ping on the command line separated by blanks. In this case, dceping does not ping any DCE core services or
the services listed in /opt/dcelocal/hpadmin/etc/nondcesvc. The service_name specified could be either a name in the DCE Cell Directory
Service Namespace or an RPC string binding. It is not
