.Sh DESCRIPTION
|
|
.Nm 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
|
|
.Nm ipropd-slave .
|
|
.Pp
|
|
The slaves are specified by the contents of the
|
|
.Pa slaves
|
|
file in the KDC's database directory, e.g.\&
|
|
.Pa /var/heimdal/slaves .
|
|
This has principals one per-line of the form
|
|
.Dl iprop/ Ns Ar slave Ns @ Ns Ar REALM
|
|
where
|
|
.Ar slave
|
|
is the hostname of the slave server in the given
|
|
.Ar REALM ,
|
|
e.g.\&
|
|
.Dl iprop/kerberos-1.example.com@EXAMPLE.COM
|
|
On a slave, the argument
|
|
.Fa master
|
|
specifies the hostname of the master server from which to receive updates.
|
|
.Pp
|
|
In contrast to
|
|
.Xr hprop 8 ,
|
|
which sends the whole database to the slaves regularly,
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
The changes are propagated over a secure channel (on port 2121 by
|
|
default).
|
|
This should normally be defined as
|
|
.Dq iprop/tcp
|
|
in
|
|
.Pa /etc/services
|
|
or another source of the services database.
|
|
The master and slaves
|
|
must each have access to a keytab with keys for the
|
|
.Nm iprop
|
|
service principal on the local host.
|
|
.Pp
|
|
There is a keep-alive feature logged in the master's
|
|
.Pa slave-stats
|
|
file (e.g.\&
|
|
.Pa /var/heimdal/slave-stats ) .
