CHAPTER 9
Administering Systems

Displaying System-Specific Information

Configuring Additional Swap Space (mkfile, swap)

Creating a Local Mail Alias (/etc/mail/aliases)

THIS CHAPTER DESCRIBES COMMANDS THAT ARE SPECIFIC TO INDIVIDUAL systems. It also shows how to configure additional swap space and how to create a local mail alias.

Displaying System-Specific Information

Use the commands in this section to find system-specific information such as the host ID number, hardware type, processor type, OS release level, system configuration, how long the system has been up, and system date and time. The following sections also describe how to set the system date and time and change the time zone for a system.

Determining the Host ID Number (sysdef -h)

To find a system's host ID number, type sysdef -h and press Return. The host ID for the system is displayed. This command replaces the SunOS 4.x hostid command:

oak% sysdef -h
*
* Hostid
*
  554Ø95cc
oak%

Determining the Hardware Type (uname -m)

To find the hardware type of a system, type uname -m and press Return. The hardware type (architecture) for the system is displayed. The SunOS 4.x arch command, which provided similar information, is not available in SunOS 5.x:

oak% uname -m
sun4m
oak%

Determining the Processor Type (uname -p)

To find the processor type for a system, type uname -p and press Return. The processor type for the system is displayed. This command replaces the SunOS 4.x mach command:

oak% uname -p
sparc
oak%

Determining the OS Release (uname -r)

To find the OS release level for a system, type uname -r and press Return. The OS (kernel) release is displayed:

oak% uname -r
5.6
oak%

Displaying System Configuration Information (prtconf)

To display the configuration information for a system, type prtconf and press Return. The system configuration information is displayed:
