HP XC System Software Administration Guide Version 4.0

Notes:
Installing a package in a nondefault location means that you must update the corresponding
modulefile; you might need to edit the PATH and MANPATH environment variables. Other changes
are based on the software package and its dependencies.
If you have installed a variant of the package, you might need to create a parallel modulefile
specifically for the variant. For example, you might have a standard application that you need
to keep separate from a beta version of the same application; in this case, you would set up a
parallel modulefile and adjust it accordingly.
1.10 Security
This section describes measures for maintaining the security of the HP XC system.
1.10.1 Administrator Passwords
During system installation, you assigned the following passwords:
• Root password
Used to access the superuser account, to perform system administration, and to invoke
management tools.
• Database administrator password
Used for changes to the configuration and management database.
• Console port devices password and user name
Used to communicate with the console ports of the nodes in the system: Integrated Lights
Out (iLO), MP (Management Processor), and Intelligent Platform Management Interface
(IPMI).
All user names and passwords for all consoles on all nodes must be the same.
• Nagios configuration password
Used to access the Nagios system and network monitoring application.
• Switch monitor password
Used to access the Quadrics® or InfiniBand® switch monitor.
• Administrator password for ProCurve switches
Used for configuration of system administration switches. Ideally, there should be a single
password for all ProCurve switches in the system. This password was set when the hardware
was prepared before installation.
For information on changing these passwords, see “Changing Administrative Passwords”
(page 162)
1.10.2 Firewall
The HP XC system maintains a firewall to block communication on unused ports. For information
about the firewall, see Chapter 12 (page 153).
1.10.3 Secure Shell (ssh)
Secure Shell (ssh) is the preferred method for accessing the HP XC system. Typically, a user
accesses the HP XC system using ssh to get a login shell or to execute commands.
The ssh service also enables file transfer using the scp or sftp commands over the same port
as ssh. The typical r* UNIX® commands (rsh, rcp, rlogin) are not on an HP XC system by
default because of their inherent insecurity. The ssh command transfers all login and password
