Description Davide Bolcioni 2004-11-17 18:20:52 UTC

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
/var/log/messages shows:
Nov 17 19:11:37 host ntpd[4047]: configure: keyword "authenticate"
unknown, line ignored

Version-Release number of selected component (if applicable):
dhclient-3.0.1-11

How reproducible:
Always.

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.
  
Actual results:
As above.

Expected results:
A valid configuration.

Additional info:
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
Bugzilla ?

Comment 1 Davide Bolcioni 2004-11-17 18:30:40 UTC

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.

Comment 2 Jason Vas Dias 2004-11-17 21:17:38 UTC

 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 :
   http://people.redhat.com/~jvdias/DHCP/FC3/
 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.
