This document is
an introduction to Solaris 8 UNIX, as used on the Sun SunFire 4800 (ROHAN)
computer at San Diego State University. UNIX has very good on-line documentation.
Therefore this manual does not attempt to be a complete reference manual.
Instead, the goal is to give you general information.

1.1 Intended Audience
The SunFire 4800
(ROHAN) is available for campus instructional use; access through terminals,
X terminals, modems and Ethernet. Our primary audience are faculty and students
developing programs, but others will find it useful. The most critical parts
are sections 3.0 Where To Find Help and
5.0 The Solaris 8
Operating System. These describe how to get help, how to type commands
to the system, and the file system. This document describes UNIX for people
who are using conventional terminals. A UNIX workstation or X terminal has
additional graphical and window facilities available. You will still spend
most of your time using the commands described here.

Introduction
1.2 About the ROHAN
System
ROHAN uses Solaris
8 as its operating system. Solaris is based on AT&T System 5 release 4 UNIX
with many features of BSD 4.4 UNIX. Software is detailed in section 4.0
What Software Is Available and includes X-windows, Motif, compilers,
symbolic math and statistical programs. The hardware consists of 8 CPUs
with 8 GB of memory, one T3 Hardware Raid 18 x 73 GB, five
internal 18 GB Drives. a DDS4 DAT tape drive, and access to paid laser printing
in BA-110 and LL-200 (see section 7.3
Printing). A 3KVA UPS powers the system to protect it from power problems.

Introduction
1.3 Terms, Special
Keys and Key Sequences Used
To use Solaris,
you will need to use a terminal. The word terminal
means either a real terminal or a microcomputer running terminal emulation
software. You will talk to Solaris using your terminal's keyboard. Solaris
will talk to you through the terminal's CRT screen.

together and comprise the Internet.
Notice many keys
are labeled as they are on a typewriter. Certain keys on the terminal

Introduction
1.4 User Guidelines
The instructional
computers are multi-user systems with shared and finite hard disk drive,
memory, and CPU resources. Because of the limited nature of these resources,
users should minimize any unnecessary computing activity.
User activities on
these systems are subject to all applicable University regulations and
Federal and State laws. Any known violations of these regulations or laws
will be referred to the appropriate departments or agencies for review
and possible disciplinary and/or legal action. Please use common sense
and courtesy.
Guidelines
for using the system:
- Protect your password.
You are responsible for the activities in your account, so do not let
anyone else use your account.
- Do not attempt
to guess passwords, break in to other accounts, or defeat security mechanisms
in any computer system or computer network. Do not attempt to access
other user or system files without permission.
- Do not run programs
or issue software commands that will interfere with the normal activities
and operations of a user or system.
- Your account is
to be used for University related work only, not for commercial purposes.
- Obtain permission
before reproducing or accessing copyrighted software.
- The proper use
of electronic mail comes down to common sense and good citizenship!
Do not send unwanted or harassing Email or files to any user or system.
- Do not create publicly
readable files of harassing graphics material or display them in computer
labs.
- Do not play computer
games in the labs during busy times.
- Abide by all rules
and regulations of remote computer systems, networks, and network bulletin
boards.
- Abide by the Student
Responsibilities for Academic Computing Use.

Connecting to ROHAN
2.2 Connecting Via
Modem
Academic users can
gain entry using the following parameters and phone numbers to reach SDSUnet
and the academic host computer, ROHAN, using modem terminal emulation software:
- Baud Rate (Speed
of Modem): 14.4, 28.8, or 33.6 bps
- Parity: None
- Start bits: 1
- Data bits: 8
- Stop bits: 1
- Duplex: Full
- Echo: None or Remote
The modem must be
at least 14.4 kbps or faster for all connections. All of the SDSU modems
are high speed with a maximum baud rate of 33.6 kbps.
Student access to
the SDSU modem pool is limited to 48 free modems that have a restricted
connection time of two hours. Students can read and send Email
as well as complete homework assignments, but they will only be able to
access SDSU specific World Wide Web information. The student access number
is: (619) 594-9900.
SDSU has a dial-in
modem pool consisting of 288 modems dedicated to provide free, unlimited
Internet access to faculty and staff. There are multiple phone numbers
that SDSU faculty and staff can use to access SDSUnet from different parts
of San Diego County. For a complete list of SDSUnet San Diego County Numbers
go to URL -- http://tns.sdsu.edu/helpdesk/accessdocs.html.
Instructions for
dialing into the system vary widely depending upon the platform and software
being used. In many cases, after the dialer has successfully connected
to SDSU, it is necessary to press the ENTER key 3 or 4 times before
being prompted to input a TACACS username and password. After this information
is entered correctly, the system will display a freeforall prompt and
ROHAN can be accessed as well as other host computers on the Internet.

2.3 Accessing Your
Account
To login to your
ROHAN account, connect to rohan and enter your username
and password in response to the login prompts. Your username and password
are case sensitive. This means abcd and ABCD are different words. Most commands
as well as your username are lower case.
Once you are logged
in, the system will ask your terminal type if it does not know. Most terminals
and terminal emulation software support the vt100 terminal type. The rohan%
is the default C shell prompt and indicates that the computer is waiting
for you to type. When the rohan% prompt is displayed, any system
command can be entered, programs compiled, files created and so forth.

2.4 Passwords
Your password is
a sequence of characters which the system uses to make sure you are really
you. You should keep this password secret, so that others can't use your
username. See section 1.4 User Guidelines
for user responsibilities.
You can change your
password by the command passwd after logging in. It is
a good idea to change your password now and then, as well as select a
password that is not easy to guess. If you suspect that someone else is
using your username, you should certainly change it.
To change a password,
type: rohan% passwd
You will be prompted
with:
- Old password:
- <--Enter
your old password
- New password:
- <--Enter
your choice of new password (at least 6 characters)
- Retype new password:
- <--Reenter
your choice of new password.
If you lose your
password, follow one of these procedures:
- Students
who received their account from their class instructor should see that
instructor for all passwords.
- Faculty Accounts
and Students who have activated their own account can obtain
a #0540 Replacement for Lost Password form in
LL-200. Fill out and return form to LL-200. A valid SDSU ID card must
be presented for verification.

2.5 Logging Off Your
Account

stopped jobs, you have jobs in the background. Typing logout
a second time will abort the background jobs and log you out. Type jobs
to see what you have in the background. See section 5.3.2
Job Control, or man csh for more information.
