Hi,

      I am using NTP 4.2.0.20040617-r2 in Gentoo 2.6 kernal.When I am 
trying from the client using  ntpdate -d 192.168.0.25, I am getting the 
error like "ntpdate[7170]: no server suitable for synchronization 
found". Can Sombody help me.

The /etc/ntp.conf is
======================
# NOTES:
#  - you should only have to update the server line below
#  - if you start getting lines like 'restrict' and 'fudge'
#    and you didnt add them, AND you run dhcpcd on your
#    network interfaces, be sure to add '-Y -N' to the
#    dhcpcd_ethX variables in /etc/conf.d/net

# Name of the servers ntpd should sync with
# Please respect the access policy as stated by the responsible person.
#server         ntp.example.tld         iburst

server in.pool.ntp.org

##
# A list of available servers can be found here:
# http://www.pool.ntp.org/
# http://www.pool.ntp.org/#use
# A good way to get servers for your machine is:
# netselect -s 3 pool.ntp.org
##

restrict 127.0.0.1 nomodify

# you should not need to modify the following paths
driftfile       /var/lib/ntp/ntp.drift
logfile         /var/log/ntp.log
#server ntplocal.example.com prefer
server sysnet-gateway25.naturesoft.net

# Warning: Using default NTP settings will leave your NTP
# server accessible to all hosts on the Internet.

# If you want to deny all machines (including your own)
# from accessing the NTP server, uncomment:
#restrict default ignore
# To deny other machines from changing the
# configuration but allow localhost:
#restrict default nomodify nopeer


# To allow machines within your network to synchronize
# their clocks with your server, but ensure they are
# not allowed to configure the server or used as peers
# to synchronize against, uncomment this line.
