From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830 Description of problem: A bug in the handling of ntp in the dhclient-script component of the dhclient package (which can't be selected anywhere in bugzilla, I might add) causes the dhcp-configured ntp servers to be ignored because of the default restrict policy. Version-Release number of selected component (if applicable): dhclient-3.0pl1-9, dhclient-3.0pl1-15 How reproducible: Always Steps to Reproduce: 1. configure dhcp to set ntp servers 2. let the client get it's info from the dhcp server 3. ntp doesn't work because the /etc/ntp.conf doesn't list the servers as 'unrestricted', so the servers are ignored. Actual Results: Time wasn't sync'ed (sp?) properly, causing confusion. Expected Results: NTP should have sync'ed time, of course :-) Additional info: patch for dhclient-script below: --- /sbin/dhclient-script 2003-01-13 14:26:32.000000000 +0100 +++ /sbin/dhclient-script.ntp 2003-01-13 14:26:26.000000000 +0100 @@ -157,6 +157,7 @@ :> /etc/ntp/step-tickers for I in $new_ntp_servers; do echo "server $I" >> /etc/ntp.conf + echo "restrict $I" >> /etc/ntp.conf echo "$I" >> /etc/ntp/step-tickers done fi
dhclient comes from the dhcp source package.
Sorry, forgot to do rpm -qf /sbin/dhclient-script ;-) I learned only recently that the selection of packages seems to be based on the source rpm, which can generate more than one binary rpm IIRC. Hence the confusion. I might add that the way this script sets the defaults is counter-intuitive and IMHO contrary to unix tradition. Every configuration and default should be defined in /etc, not hidden in a script in /sbin. Perhaps it's best to rewrite dhclient-script to allow for this?
Current release has the following code in it. Available on Rawhide. :> /etc/ntp/step-tickers for I in $new_ntp_servers; do echo "restrict $I nomodify notrap noquery" >> /etc/ntp.conf echo "server $I" >> /etc/ntp.conf echo "$I" >> /etc/ntp/step-tickers done
