Hi guys,

I’m trying to configure a local NTP Server (Linux) on my Network & I’d like my other servers to be synchronised to this server. The challenge is that I have different OS platforms (Linux, Windows…) Am not really sure how to configure the clients on these platforms to sync with my Linux NTP Server.

Please help. Thanks

See if this is along the lines of what you are trying to do.

I’m not sure on the Linux boxes but you should be able to use the normaly steps of specifying the IP address of the NTP in the Windows servers. The windows servers should be really easy if they are on a domain as you just configure your role holder to get time from your Linux box, the other domain servers will pull time from that Windows domain role holder.

Should be pretty simple if you just map the clients to the ip address, or do it with GPO. I’ve seen this done several times. On the linux side just run ntpdate -u <FQDN or Server IP

Setting option 42 on your DHCP scope should do it, also. This obviously only works for clients set up for dhcp and not for statically assigned ones.

On the windows side, only synchronize the DCs to your internal time severs, the windows clients will automatically sync to the domain controllers on your network. For your non-windows clients set the dhcp option for the time servers, they will pick up the time server from the dhcp config. If you have a work group environment then you will need to update the w32time service to use the ntp time servers as outlined by scott.

As for the linux systems pick 2 linux systems to be your internal time servers and have these two time servers synchronize with the internet. Then update the /etc/ntp.conf on all other linux / *nix systems to synch to these two internal time servers. The internal domain controllers should also reference these 2 linux systems you setup as your internal time servers.
