From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: (This bug should be filed under dhclient. However, dhclient is missing from Bugzilla. So I file it here). dhclient writes a ntp.conf file for NTP which contains the line authenticate yes However, since 4.2.0, ntp mo longer supports the "authenticate" command which results in Dec 26 16:52:16 localhost ntpd[3084]: configure: keyword "authenticate" unknown, line ignored getting logged to the syslog. This is not a big deal, because authentication is activated by default now, but the manual _should_ mention, that the popular "authenticate no" line to enable simple network broadcasting no longer works, but must be replaced by disable auth Then multicast and broadcast for time will work again. However, dhclient should write a correct ntp.conf file (omitting the authenticate line). Version-Release number of selected component (if applicable): ntp-4.2.0.a.20040617 How reproducible: Always Steps to Reproduce: 1. Launch an DHCP client host where the DHCP server reports an NTP host 2. Look at the /etc/ntp.conf file 3. Look at the daemon syslog file Actual Results: No errors Expected Results: See above. Additional info:
$ rpm -qif /sbin/dhclient|fgrep Source Group : System Environment/Base Source RPM: dhcp-3.0.1-11.src.rpm
This problem is fixed in dhclient-3.0.1-14, which has been in FC4/rawhide for nearly a month now. The dhclient script now merges in only NEW server entries and does not remove local clock server entries. I'm kicking off the process of pushing it to FC3 upgrades . Meanwhile, you can download it from: http://people.redhat.com/~jvdias/dhcp/FC3
Latest version is now dhcp-3.0.1-16, with the NTP (and other) fixes. You can download it from: http://people.redhat.com/~jvdias/dhcp/FC3
