[--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/
[email protected]
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 master. 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.
