Table 1-3 Command Fanout Commands (continued)

Command	What it Does
cps	Distributes a ps(1) command to multiple
	hosts in parallel. In a Serviceguard cluster,
	issues command cluster-wide by default.

When to Use it

To collect process information from groups of systems simultaneously.

cuptime	Reports uptime(1) information for	To check uptime, users, and load averages.
	multiple systems. In a Serviceguard
	cluster, issues command cluster-wide by
	default.

cwall	Displays a wall(1M) broadcast message
	on multiple hosts. In a Serviceguard
	cluster, issues command cluster-wide by
	default.

To broadcast a message to all logged-in users across a group of systems.

Table 1-4 Utility Setup Command

Command	What it Does
csshsetup	For the current user, performs a secure
	shell (ssh) public key distribution to
	multiple systems.

When to Use it

To greatly simplify ssh key distribution. pdsh and the command fanout (cexec-related) commands all rely on a proper ssh key distribution. The csync_wizard requires ssh access to managed clients. For example, in a Serviceguard cluster, this allows ssh access from any member to any other member, so pdsh and cexec can be used from any cluster member.

1.2 Open Source Components

The open source components and their commands are described in the following table. These open source components used by DSAU are based on the high level cfengine language. For additional information on cfengine, see the cfengine manpage; for the individual commands, see their respective manpages and open source documentation at /opt/dsau/doc. For supported open source options, refer Appendix A (page 87) HP-Supported Open Source pdsh Options.

Table 1-5 Open Source cfengine Commands

Command	What it Does
cfagent	System configuration agent that performs the configuration actions defined in a
	configuration policy file.
cfexecd	A scheduling and report service. This is an optional component.
cfkey	Security key generation tool. cfkey is run once on every host to create a
	public/private key pair.
cfrun	Tool to activate a remote cfagent.
cfservd	A file server and remote activation service.

Table 1-6 Open Source pdsh Commands

Command	What it Does
dshbak	Formats output from pdsh commands; consolidates identical output from multiple
	hosts.
pdcp	Tool to make file and directory copies in parallel to a set of remote systems.
pdsh	Tool to execute shell commands in parallel across a set of systems.
