NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to use in a distributed denial-of-service (DDoS) attack. Please also take this opportunity to defeat denial-of-service attacks by implementing ingress and Egress filtering through BCP38.
ntp-4.2.8p3 was released on 29 June 2015, and addresses leap-second issues and a minor security issue.
Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.

Plotting NTP Stats
Part of the software I use to plot the ntp stats for my Soekris NET 4801. This software uses environment variables passed to Gnuplot to control aspects of the plot apperance on the fly (e.g. adjusting for Daylight Saving Time changes) and plots the data in local time rather than UTC. The
files are retrieved from the time server over http and the finished plots are uploaded to my public web-server using
These files are licensed under the GNU General Public License
Some of the plot files have not yet been released to the public...
Debian ntp-dev package update "one-liner"
is useful for situations where the binary ntp-dev Debian packege
is not usable (e.g. non-i386 architectures)
cd /usr/local/src/ntp && \
apt-get update && rm -rf ntp-dev* && dpkg-repack ntp-dev && \
apt-get --build source ntp-dev && \
dpkg -i `ls ntp-dev_*_amd64.deb | tail -n1`
