To all who replied to my original post, Thank you very much for your input and insight. I have read every post in this thread and have come to the following conclusions. The ntpdate function is the brute force method of syncing the pc hardware clock with any ntp internet server one wants to use for this purpose. For a home dialup ISP gateway box this is the recommended method of keeping the gateway FBSD box's clock accurate every time the box is booted. The small servers defined in inetd.conf include the timed & timedc. This set of services use a different method of pc clock syncing than ntpd. The main point is it does not create a ntp protocol time server that can be accessed by IP address. The final option is ntpd. This function does get the time from a internet ntp server to update the requesting FBSD box, and keeps the clock accurate by making very small adjustment over long periods of time. It can be configurated to broadcast time packets to all machines on the private net it is connected to. It is not a ntp time server with a unique IP address. Only FBSD boxes on the private net with ntpd clients can hear the broadcasted time packets and adjust there clocks. The only way for a Winbox to use this function is to have Samba running on the FBSD to fake out the Winboxs into thinking it's a NT or Win2k server. This sure is overkill just to get synced time across the private net. One responder did point out that there is a Winbox program which will utilize the ntpd info to set the Winbox clock. This may be a option if I ever have to upgrade all the Winboxs to a common release of Windows, other than that it would be to hard to roll out a new clock program to all the Winbox users. The main point again is it does not create a ntp protocol time server that can be accessed by IP address from other Winboxs on the private net. So I would say this pretty well covers the facilities that are delivered as part of the base install. None of then are compatible with what is currently running on the Winboxs in my private LAN behind the FBSD gateway/firewall. It is now time to review the ports for a ntp time server. Does anybody out there know of or use a FBSD time server port? Thanks again for all your combined help in this matter.

My LAN is full of winboxs? Each one has this TSR pgm socketWatch. This pgm checks a internet time server and resets the pc time. Instead of 700 machines hitting the internet time server once a hour, I would like to setup ntpd to go out to the internet time server once a hour for a update to the FBSD machine and them have my windows LAN boxes get the time from FBSD time server. I could not find anything in the ntpd man page that talks about setting up ntpd as a time server to service time requests from other machines. What I read is that ntpd will broadcast the time down the LAN network for any listening clients to pick and user the time info. The win SocketWatch pgm does not work that way. Is ntpd the wrong software product for what I want to do? Does anybody know of something better suited? Thanks Joe My LAN is full of winboxs? Each one has this TSR pgm socketWatch.
