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.
The final two security bugs reported by Google's Security Team have been fixed as of ntp-4.2.8p1.
A new set of mode 6 vulnerabilities has been discovered and, while these vulnerabilities can be reduced by making sure you have
restrict default … noquery in your
ntp.conf file, the best and most complete way to avoid these vulnerabilities is to install and deploy
ntp-4.2.8p1 which was released on 04 February 2015.
Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.
Excerpt From Army Doctrine Publication 6-22
"Toxic leadership is a combination of self-centered attitudes, motivations, and behaviors that have adverse effects on subordinates, the organization, and mission performance. This leader lacks concern for others and the climate of the organization, which leads to short- and long-term negative effects. The toxic leader operates with an inflated sense of self-worth and from acute self-interest. Toxic leaders consistently use dysfunctional behaviors to deceive, intimidate, coerce, or unfairly punish others to get what they want for themselves. The negative leader completes short-term requirements by operating at the bottom of the continuum of commitment, where followers respond to the positional power of their leader to fulfill requests. This may achieve results in the short term, but ignores the other leader competency categories of leads and develops. Prolonged use of negative leadership to influence followers undermines the followers' will, initiative, and potential and destroys unit morale."

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`
