Synchronization with ntpdate
Hello!
I'm trying to synchronize a client with an ntpdate server.
The ntp.conf file from the server has the following lines:
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help
driftfile /var/lib/ntp/ntp.drift
# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable
# You do need to talk to an NTP server or two (or three).
server pool.ntp.org
server 127.127.1.0
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.
# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify noquery
restrict -6 default kod notrap nomodify noquery
# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1
# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
broadcast 192.168.1.255
broadcastdelay 0.008
# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines. Please do this only if you trust everybody on the network!
disable auth
broadcastclient
When I try from client #ntpdate 192.168.1.1
the answer is:no server suitable for synchronization found
Even if i try to synchronize from a web server like:
#ntpdate pool.ntp.org
the same answer:no server suitable for synchronization found
Don't know where is the problem.

Are you able to ping pool.ntp.org ?
[root@server ~]# ntpdate pool.ntp.org

Do you know for sure that an ntp daemon (ntpd) is running on the 192.168.1.1 machine ? That is in the private non-routable ip-block.
