ccp(1M) System Administration Commands ccp(1M) NAME
ccp - the Sun Cluster System Cluster Control Panel GUI SYNOPSIS
$CLUSTER_HOME/bin/ccp [-s] [ -l username] [-p ssh-port][clustername | nodename] DESCRIPTION
The ccp utility is a launch pad for the cconsole, crlogin, cssh, and ctelnet cluster utilities. The ccp utility also accepts the standard set of X Window System command line arguments. OPTIONS
The following options are supported: -l username Specifies the user name for the ssh connection. This option is passed to the cconsole, crlogin, or cssh utility when the utility is launched from the CCP. The ctelnet utility ignores this option. If the -l option is not specified, the user name that launched the CCP is effective. -p ssh-port Specifies the Secure Shell port number to use. This option is passed to the cssh utility when the utility is launched from the CCP. The cconsole, crlogin, and ctelnet utilities ignore this option, If the -p option is not specified, the default port number 22 is used for secure connections. -s Specifies using Secure Shell connections to node consoles instead of telnet connections. This option is passed to the cconsole utility when the utility is launched from the CCP. The crlogin, cssh, and ctelnet utilities ignore this option. If the -s option is not specified, the cconsole utility uses telnet connections to the consoles. To override the -s option, deselect the Use SSH checkbox in the Options menu of the cconsole graphical user interface (GUI). OPERANDS
The following operands are supported: clustername If provided, this option can be passed on as an argument to a tool in CCP's set of tools. The clustername argu- ment can be specified by adding $CLUSTER in a tool's command line property. ENVIRONMENT VARIABLES
