*Software: New NTP Version for Windows (4.2.4p8 at lennon) - Security Update*

Bad Pyrmont, 2009-12-09

Yesterday the NTP Public Services Project announced the availability of 
a security update for their stable NTP version 4.2.4p7. Based on the new 
point release 4.2.4p8 Meinberg Radio Clocks updated their NTP Installer 
for Windows and the new installer will now install NTP 4.2.4p8 and the 
current version of OpenSSL (0.9.8l) on all Windows NT, Windows 2000, 
Windows XP, Windows 2003, Windows Vista, Windows 2008 and Windows 7 systems.

Meinberg provides a secure and easy-to-use installer for NTP which 
allows everybody to install the stable version of the reference 
implementation of NTP as provided by www.ntp.org in cooperation with the 
NTP Public Services Project. The installer can be used on all systems 
running a Microsoft Windows Operating system (starting with Windows NT 

A simple automatic update mechanism optionally allows to simply replace 
the binaries of an installed NTP version. This is detected when the 
installer starts and can be safely selected for 4.2.4p7 installations. 
Older NTP versions should be removed before the new NTP 4.2.4p8 version 
is installed. Uninstalling the existing version can be performed by the 
installer as well and will be offered if the user does not want to use 
the simple binaries replacement approach.

The download link for the NTP installer can be found on the Meinberg NTP 
Download page. The installer for version 4.2.4p8 has been nicknamed 
"lennon" in remembrance of the death of John Lennon on December 8th, 
1980. See http://en.wikipedia.org/wiki/John_Lennon for further information.
