check your ntp.conf file for the following line at the end: restrict default ignore if it's there, comment it out (#) and see if local machines can then get time from your 'master clock machine'. It's in there for security - preventing outsiders from wasting your bandwidth getting time from your server, there are other settings you can have there which prevent outsiders but allow local machines to connect. I have: restrict default nomodify nopeer noquery restrict xxx.xxx.xxx.xxx mask mmm.mmm.mmm.mmm restrict 127.0.0.1 (replace xxx.xxx.xxx.xxx with your netblock IP and mmm.mmm.mmm.mmm with your mask)
Also, multicastclient seemed to give me trouble so I commented that out. The config file for ntp has a lot of examples, some of which are not needed or desired in some setups. if you have a server line and a driftfile line, it should work. again, check if it's working and staying synced with 'ntpq -p' offset value and reach values are possibly the most important there. Ideal value for reach is 377 0 means it's not working at all. offset value is in mS ( 1.000 = .001 seconds). local machines should have value very near 0 there, value to the external machine you're connecting to should be less than 100 ( .1 second), if greater, maybe another external clock source would be a good idea. As stated previously, xntpd has some security issues, but I think it was an issue with outsiders being able to mess with your clock without permission, but I guess if they were to have your system trying to connect to thousands of machines for time, it could create a DoS condition.
