Drew wrote I don't think this is correct. ntpd *IS* a time server and the IP address is the address of the machine you run it on. On my private network, I have a FBSD box on 192.168.20.4. I have a Win2K machine on 192.168.20.3. I have a ntp client program called "Automochron" that runs on the Win2K machine. In the client, I have the time server listed as 192.168.20.4 (the FBSD machine). The Win2K client gets time updates. Joe writes back. When you say "I have a FBSD box on 192.168.20.4." Is this the IP address of the Nic card on the FBSD box that's talking to the machines down line, or is it the public IP address your private network is known by? 127.0.0.0 is the only IP address that I know of that is this FBSD box. I have 3 Nics, How would I get all the Winboxs on all the Nics to point to one single IP address for the ntp time server? Drew answers: It's my internal interface (downline). If all your Winboxes can connect to your FBSD box then just use whatever address that is that your Winboxes use to connect. For example, let's say NIC1 serves Win subnet A and NIC2 serves Win subnet B. Then you would set Winboxes on subnet A to get ntp updates from the ip address of NIC1 and Winboxes on subnet B to get ntp updates from the ip address of NIC2. Or if you have the appropriate routers (this may be your FBSD box alone or other routers) such that all 3 of your subnets can communicate with the others (i.e. Winbox on NIC2 can talk to Winbox on NIC1) then it shouldn't matter which IP address you tell the Winboxes to use as all NICs are reachable.
