All,
How do you set a Solaris 9 server which received ntp updates from a ntp server to broadcast them on a local subnet. I have created a /etc/inet/ntp.conf file to receive the updates from a server on network and need to make this server become like a ntp relay from the main server.

All here, thank you for listening. Now I've set up a Linux NTP server by adding a external windows NTP server in /etc/ntp.conf. Then I start the ntpd daemon. But how often does the Linux NTP server update its time with the external NTP server? I've looked up everywhere but found no information... (1 Reply)

Hi,
I have two ntp servers in my cluster and I want all the nodes in my cluster to sync with either of the ntp servers or just one. Unfortunately it keep rotating the sync, between my ntp server 1, ntp server 2 and local. Is there anyway I can change the sync to avoid local?

iprop
IPROP(8) BSD System Manager's Manual IPROP(8)
NAME
iprop, ipropd-master, ipropd-slave -- propagate changes to a Heimdal Kerberos master KDC to slave KDCs
SYNOPSIS
ipropd-master [-c string | --config-file=string] [-r string | --realm=string] [-k kspec | --keytab=kspec] [-d file | --database=file]
[--slave-stats-file=file] [--time-missing=time] [--time-gone=time] [--detach] [--version] [--help]
ipropd-slave [-c string | --config-file=string] [-r string | --realm=string] [-k kspec | --keytab=kspec] [--time-lost=time] [--detach]
[--version] [--help] master
DESCRIPTION
ipropd-master is used to propagate changes to a Heimdal Kerberos database from the master Kerberos server on which it runs to slave Kerberos
servers running ipropd-slave.
The slaves are specified by the contents of the slaves file in the KDC's database directory, e.g. /var/heimdal/slaves. This has principals
one per-line of the form
iprop/slave@REALM
where slave is the hostname of the slave server in the given REALM, e.g.
iprop/kerberos-1.example.com@EXAMPLE.COM
On a slave, the argument master specifies the hostname of the master server from which to receive updates.
In contrast to hprop(8), which sends the whole database to the slaves regularly, iprop normally sends only the changes as they happen on the
master. The master keeps track of all the changes by assigning a version number to every change to the database. The slaves know which was
the latest version they saw, and in this way it can be determined if they are in sync or not. A log of all the changes is kept on the mas-
ter. When a slave is at an older version than the oldest one in the log, the whole database has to be sent.
The changes are propagated over a secure channel (on port 2121 by default). This should normally be defined as ``iprop/tcp'' in
/etc/services or another source of the services database. The master and slaves must each have access to a keytab with keys for the iprop
service principal on the local host.
There is a keep-alive feature logged in the master's slave-stats file (e.g. /var/heimdal/slave-stats).
Supported options for ipropd-master:
-c string, --config-file=string
-r string, --realm=string
-k kspec, --keytab=kspec
keytab to get authentication from
-d file, --database=file
Database (default per KDC)
--slave-stats-file=file
file for slave status information
--time-missing=time
time before slave is polled for presence (default 2 min)
--time-gone=time
time of inactivity after which a slave is considered gone (default 5 min)
--detach
detach from console
--version
--help
Supported options for ipropd-slave:
-c string, --config-file=string
-r string, --realm=string
-k kspec, --keytab=kspec
keytab to get authentication from
--time-lost=time
time before server is considered lost (default 5 min)
--detach
detach from console
--version
--help
Time arguments for the relevant options above may be specified in forms like 5 min, 300 s, or simply a number of seconds.
FILES
slaves, slave-stats in the database directory.
