NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

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 *stats files are retrieved from the time server over http and the finished plots are uploaded to my public web-server using UUCP.

• Makefile: Makefile for controlling the plotting process
• loopstats.plot: Gnuplot control file for plotting loopstats; must be used with the Makefile

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"

This 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`
