Hardware Information

SunOS is an older text-based UNIX that runs on Sun SPARC. Solaris is an enhancement of SunOS that includes a graphic user interface.

"Sun OS is basically all the "real unix" stuff. Solaris is a bundling of Sun OS with all the "window dressing" (pun intended) like CDE (Common Desktop Environment) a.k.a. the GUI, and other OS "accessories" like a Web browser, etc."

Intended purpose

server/mainframe: medium to large scale servers

desktop/workstation: workstations (for those with UNIX familiarity)

Kind of OS

proprietary System V Release 4-based UNIX

"SunOS is part of Solaris. Current versions of SunOS were originally based on the AT&T SVR4.0 flavor of Unix. Since then it has diverged. SunOS is compliant with the Open Group's Unix 98 specifications
(http://www.UNIX-systems.org/)." -Greg Onufere68

Release Date 4.0; replaced by Solaris

Current Version 5.8

Hardware Supported: Sun SPARC

Maximum Number of Processors : 64

"SunOS 4 supports 1 processor per system except in some very old configurations (4/6xx series machines with slow processors). SunOS 5 supports up to 64 processors in a single box (the E10000, for example)."

Number of bits : 64

Kernel : proprietary

Posix : compatible

File System Supported : preferred file system : UFS (NRWF ) e21

Read/ write through third party software : SMB (RW) through SAMBA

Other systems Emulated : www.novalink.com/freeport-express " FreePort Express is a binary translator (running on Alpha) which permits you to convert your SunOS 4.1.x (same as Solaris 1.x) user executables into Digital Unix executables in minutes.

FreePort Express runs under Digital Unix V3.0 or later, and is available FREE of charge (hence the name)

User Interface (text ): Unix Shells

For our system it is SunOS paris 5.8 Generic_108528-07 sun4u sparc SUNW, Ultra-4
Type at the prompt

%uname -i

It prints the name of the hardware implementation <platform>. We have SUNW,Ultra-4 platform.
Type at the prompt

%uname -p

This command prints the current host's ISA or processor type.For our system it is sparc.
Type at the prompt

%uname -n

It prints the nodename <the nodename is the name by which the system is known to a communication network>.

If you type this command it will be paris.
Type at the prompt

%uname -r

It prints the operating system release level. It is 5.8
Type at the prompt

It prints the name of the operating system. We have SunOS.
Type at the prompt
