OpenNTPD is a FREE, easy to use implementation of the Network Time
Protocol. It provides the ability to sync the local clock to remote
NTP servers and can act as NTP server itself, redistributing the
local clock. OpenNTPD is primarily developed by Henning Brauer as
part of the OpenBSD Project. The portable version is made by Darren
Tucker.
You will need to add the "_ntp" user and group to /etc/passwd and
/etc/group if it's not present on your system. Without these groups,
the package will not work.
This package conflicts with the "ntp" package included with Slackware,
so only one of them should be installed at any given time.
The /etc/rc.d/rc.ntpd script in Slackware 12.0 will not work with
OpenNTPD; be sure to move the /etc/rc.d/rc.ntpd.new over if you want
it to work.
