4. Technical Description
Upgrade NTP to version 4.
This project proposes to remove the current version 3.4 NTP
deliverables and replace them with version 4.2.5. The current
version in Solaris was released 11 years ago. The NTP project
has continued to advance the code base for the entire time.
This will be done by removing the current SUNWntpr and SUNWntpu
packages from the ON consolidation and move them to the more
appropriate SFW consolidation. In addition to the replacements
for the current deliverables, the packages will include man pages
and HTML documentation.
While not 100% backwards compatible, the incompatibilities in the
configuration file are mostly semantic in nature rather than
syntatic, with the only major exceptions being in Sun added features,
which we will not be adding. However, because of the popularity of
the "slewalways" feature, the startup method will detect the
presence of this Sun added keyword and configure the NTP daemon to
use the NTP version 4 equivalent.
The NTP community project, while not having an explicit requirement
for backwards compatibility, in 11 years
of development, including a full re-write of the configuration
code, has had no major incompatibilities were introduced.
The NTP community is very receptive to contributed code and
integration of features needed by Solaris. I am a committer on
the NTP project and I expect to work with the community to
push all fixes and changes back into the community codebase.
While the man pages are derived from the HTML documentation, they
are specific to these deliverables and as far as possible complete and
accurate regarding them. The HTML documenation, is delivered "as is"
and may or may not reflect the deliverables. A notice to this effect is
included in the man pages.
This work is being sponsored by chris.armes at sun.com.
This project seeks a minor release binding.
This project supercedes PSARC 2001/162, which should considered
withdrawn.
