Hello

I am currently working on time synchronisation in wireless sensor
networks. I am using meinberg ntp software but i am having some small
complications about ntp time server. It does not provide time to the
clients and i dont know why such is happening.

Below is the ntp configuration file

# NTP Network Time Protocol
# **** ATTENTION ****: *You have to restart the NTP service when you
change this file to activate the changes*
# PLEASE CHECK THIS FILE CAREFULLY AND MODIFY IT IF REQUIRED
# Configuration File created by Windows Binary Distribution Installer
Rev.: 1.26  mbg
# please check http://www.ntp.org for additional documentation and
background information
# Use drift file

# your local system clock, should be used as a backup
# (this is only useful if you need to distribute time no matter how
good or bad it is)
server 127.127.1.1
# but it operates at a high stratum level to let the clients know and
force them to
# use any other timesource they may have.
fudge 127.127.1.1 stratum 12

#driftfile /etc/ntp.drift
driftfile "C:\Program Files\NTP\etc\ntp.drift"
multicastclient 224.0.1.1
broadcastdelay  0.008
broadcastclient


# Use a NTP server from the ntp pool project (see http://www.pool.ntp.org)

peer ns1.savonia.fi
peer ntp.a-lab.fi iburst


# allow localhost
restrict 127.0.0.1
restrict 192.168.3.189
restrict 192.168.0.0

# Please note that you need at least four different servers to be at
least protected against

#peer 192.168.3.189

# one falseticker. If you only rely on internet time, it is highly
recommended to add
