Hello,
I have a FreeBSD cluster, all PCs running FreeBSD-Stable (as of one week ago). The cluster has a master, connected to the Internet, and the master is also router, caching nameserver and timeserver for the internal network. The master has two internet cards, and there are 6 slaves on the internal network.
Problem is, that as time goes on, the system time on master and slaves deviate more and more.
Here is my configuration for the time server configuration:
on MASTER (192.168.0.100) rc.conf: ntpdate_enable="YES" ntpdate_flags="-b time.kriss.re.kr time.nuri.net" xntpd_enable="YES" ntp.conf: # prohibit general access to this service restrict default ignore # allow hosts on the 192.168.0.0/24 subnet to query this server restrict 192.168.0.0 mask 255.255.255.0 nomodify notrap # localhost has full access to the server restrict 127.0.0.1 server time.kriss.re.kr prefer server time.nuri.net driftfile /etc/ntp.drift
on SLAVE<N> (192.168.0.<N>) rc.conf: ntpdate_enable="YES" ntpdate_flags="-b 192.168.0.100" xntpd_enable="YES" ntp.conf: # prohibit general access to this service restrict default ignore # localhost has full access to the server restrict 127.0.0.1 server 192.168.0.100 driftfile /etc/ntp.drift
The idea is that at boot-up, time is instantly synchronized once by unsing "ntpdate -b"; after that ntpd will control time adjustments.
Am I making a mistake in this setup?
Thanks, Rob.
