Hi everyone. Need some help.
I am trying to make my RHEL 4 ES machine as an ntp server for the clients in my network 172.24.0.0/16.
The server IP address is 172.24.254.254 and the clients are 172.24.0.1, 172.24.0.2 and so on.
Please note that as I do not have an Internet Connection for my network, my server would not be able to Synchronize from time servers on the internet. So it must trust its own clock and provide synchronisation to all the hosts in the 172.24. network.
How do I do this?

I have tried to configure my ntp server as its told in many tutorials.
However, when I configure the client with system-config-date, enable NTP time, remove pool1.ntp.org and others from the list, & put in the server IP address( 172.24.254.254), I get the error -
The host hostname is not reachable or does not act as an NTP server
Please Assist.
Waiting in Anticipation.............
Thanks.

Are you running any firewall on the ntp server or on the clients? You should be aware of any network security policies that are in place in your network that may prevent ntp traffic btwn hosts.

Thanks for the reply. Firewalls on all the machines in the network are disabled. No IPTABLES are configured. TCPWrappers, Netfilters are all NULL. Moreover, every other network service like DNS, DHCP, NFS, Kickstart, etc. are working perfectly between the clients and the server.
I forgot to mention above that the server runs RHEL 4 ES while the clients have RHEL 5. Dont think that should be an issue. Coz I have seen this arrangement work before. What do You think?
