Security Infrastructure
Continentalclusters for Linux B.01.00.00 uses a secure infrastructure. The following components
are used in this product:
• Continentalclusters User and Group
Continentalclusters uses Secure Shell (SSH) for all inter-cluster and node communication. A
special Continentalclusters user, conclusr and group, conclgrp are used for all communication
over SSH. This Continentalclusters user and the group are automatically created when
Continentalclusters for Linux is installed on a node. You must specify a password for this user
on all nodes in the primary and recovery clusters. When a node is no longer part of
Continentalclusters configuration, remove this user from the node.
• Continentalclusters Configuration Package
Continentalclusters for Linux version B.01.00.00 stores configuration information in a special
package on the primary and recovery clusters. This package is named ccconfpkg and is
automatically created on the primary and recovery clusters when a Continentalclusters for
Linux configuration file is applied using the cmapplyconcl command.
This package is deleted on all clusters when the Continentalclusters configuration is removed
using the cmdeleteconcl command.
IMPORTANT: Do not modify, delete, start, or stop this package using Serviceguard
commands.
Support for Modular Packages
Continentalclusters for Linux supports only modular style packages to be configured in a recovery
group. The monitor package on the recovery cluster must be configured as a modular package
using the Continentalclusters supplied modular configuration file template. Other packages in the
primary and recovery cluster which are configured in a recovery group as PRIMARY_PACKAGE,
RECOVERY_PACKAGE, REHEARSAL_PACKAGE, DATA_SENDER or DATA_RECEIVER package
must also be configured as modular packages using the Serviceguard supported modules.
