The bin and etc directories contain several scripts (sh and perl) that
should ease startup and configuration of NTP sites.
bin/monl is a monitoring script that prints out new, current and
old customers of an NTP timeserver when monitoring is
in effect.
monl has following options:
-i <regexp> (regular expression matchin IP addres to be ignored
-d <directory> where the current state is kept (default /tmp)
-v debug output
-n do not translate IP addresses into hostnames
<host> host to be analyzed
monl uses xntpdc for information gathering and is thus
limited to the NTP version xntpdc is compiled for.
bin/mvstats moves compresses and removes statistics files (useful mainly
for reference servers
etc/install creates the locally needed directories for NTP (if not residung in /etc)
etc/rc starts up daemon with configuration file and key file
etc/cron cron called monitor statistic (uses bin/monl)
etc/crontab crontab prototype for reference time servers
etc/setup sh script sourced by the other scripts for variable setup
YOU MUST EDIT THESE FILES TO REFLECT YOUR LOCAL SETUP !
READ THIS BEFORE USING THE STARTUP SCRIPTS
The startupscript etc/rc has been written for Suns and HPs. They are not
guaranteed to work elsewhere. Following assumptions have been made:
All NTP related files reside in ONE directory having following structure:
bin/* - all executables (daemon, control, date, scripts)
etc/* - startup scripts and cron scripts
conf/* - NTP configuration files
The variable NTPROOT (etc/rc, etc/install) must be edited to reflect
the NTP directory (e.g. /usr/local/NTP)
NTP config files are located via Suns arch command and have the name
conf/`arch`.`arch -k`.
These are the default configurations (usually clients). If a file with the name
conf/`arch`.`arch -k`.`hostname` is present this file will be preferred (Reference host,
gateway). If the arch command is not available no-arch is used. The arch command
is usually a shell script which echoes a string unique the the current machine
architecture.
The tickadj command has its own conf/tickconf file which is used to set host
specific tickadj values. The line with DEFAULT specifies the default tickadj
parameters, all other lines consists of <hostname> <hostid>
<tickadj parameters>. These lines need only be entered if the specified host
needs parameters different from the default parameters.
Reference clock support is provided for DCF77. If you need to initialize
certain things for reference clock support (e.g. loading STREAMS modules),
you need to edit etc/rc.
The current config files of Erlangen are included in the conf directory.
They are just for reference, but might help you a bit in setting up a
synchronisation network.
The advantage of keeping all config files centralized is the easier
administration.
We replicate the NTP directory via NFS and rdist.
When you have set up the local config files (YOUR OWN!) you can call
<NTPROOT>/etc/rc for daemon startup.
