You are right, xntpd definitally has a lot of accompanying documentation, but it took me some time to figure out how to set up xntpd for my simple requirements. I have a small local network with one machine being the time server, but without a radio controlled clock or a similar gadget. Also, I do not want it to connect to ntp servers on the internet, because I have a dial up link only. I just wanted xntpd to distribute this computer's internal clock to my network. Here the server's /etc/ntp.conf server 127.127.1.1 prefer broadcast my-network ttl 16 driftfile /etc/ntp.drift The IP address 127.127.1.1 refers to the local clock. The key is that you have to use the "prefer" keyword to convince xntpd to actually broadcast the local clock so that clients are able to synchronize to the server. I had to read the sources to figure this out. So, if anyone wants to do the same thing like I did, this might help. Andreas P.S. In order to check whether the clock synchronization actually works, I have written a small program which uses udp port daytime/37 to retrieve the current time on all reachable machines. It includes a small tcl/tk frontend. Anyone interested in this might e-mail me. -- andreas@marvin.robin.de (home) | "Beware of programmers carrying screwdrivers!" al@rtsffm.com (work) |
