Red Hat Bugzilla – Bug 139715
Invalid ntp.conf created by dhclient-script
Last modified: 2007-11-30 17:10:54 EST
Description of problem:
If DHCP provides the NTP server, dhclient-script generates ntp.conf
but uses "authenticate yes" which ntp-4.2.0.a.20040617-4 dislikes as
Nov 17 19:11:37 host ntpd: configure: keyword "authenticate"
unknown, line ignored
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure DHCP server to send NTP server option.
2. Boot client
3. Observe generated ntp.conf and the complaint in /var/log/messages.
A valid configuration.
By the way, rpm -qf shows /sbin/dhclient-script as belonging to
dhclient, but there is no dhclient component for Fedora Core 3 in this
Please note that I do not believe this is a duplicate of the various
earlier problems with ntp.conf documented in Bugzilla; I bothered with
a quick check. It seems that "authenticate yes" is no longer liked by
ntp, although it used to be fine.
The dhclient-script was overwriting the /etc/ntp.conf and
/etc/ntp/step-tickers files when it received new ntp servers
from the DHCP server.
With dhcp-3.0.1-14, DHCP now merges in only the new servers
with the existing ntp.conf contents, so other non-server
configuration is preserved.
dhcp-3.0.1-14 will be available from tomorrow in the Fedora
Development (rawhide) repository, and from :
Please test dhcp-3.0.1-14 and let me know how it works - then
if it works ok I'll push it to FC3 updates.
