SCENARIOS FOR USING ARPANET COMPUTERS
This scenario booklet is provided to facilitate the use of ARPANET
host computer systems via the ARPANET. The objective of these
scenarios is to aid a user in sampling host computers on the ARPANET,
thereby stimulating this interest in using ARPANET.
The scenarios describe the login procedure, the use of some simple or
interesting facilities, and obtaining on-line help facilities such as
on-line documentation and interactive dialog with experienced users
via "link" or "message" type mechanisms. The use of TELNETS for
"piggy-back login" is included to help system programmers in
debugging and testing their protocol implementations. An exercise of
editing and running a very simple program is also included, where
appropriate.
The scenarios assume the environment of the MIT-DMCG PDP-10 computer
system, but are readily adaptable to use from other systems. The
annotated script is provided to assist you in the use of a particular
host computer. Comments are enclosed in parenthesis, and user input
is underlined. In the scripts, a carriage return is indicated by
'', and a space by blank (i.e., no type). Escape to local user
TELNET is indicated by backslash, the default escape character in the
MIT_DMCG system. Additional blank lines have been introduced in many
instances to improve readability of the script.
ACKNOWLEDGMENTS: The author wishes to acknowledge the help of Bob
Bressler, Rich Guida, Bob Metcalfe, Jim Michener, and Neal Ryan in
preparing this Scenarios booklet.
NOTE: Your comments and suggestions will be greatly appreciated.
Please direct all comments to Abhay Bhushan, Room 208, 545 Technology
Square, Cambridge, Mass 02139. (Tel. 817-864-6900 x1428).

SRI (NIC) PDP-10 TENEX Network address 2.
_________________________________________
NIC is best used in character-at-a-time mode with remote echo. After
connection is completed you should change your mode to full-duplex at
NIC (their default is half-duplex). NIC can also be used in half-
duplex (with local echo), line-at-a-time mode, but use is not as
convenient. Although NIC commands are similar to BBN TENEX, the NLS
subsystem is different.

________________________________________
(The SRI (AI) computer uses the TENEX operating system, and is
similar to the system at BBN. We have not been able to log into SRI
(AI) system as they are currently not functioning as a server. Hence
no scenario is provided. This section will be updated as soon as SRI
(AI) is able to accept login over the ARPANET.)

UTAH PDP-10 TENEX Network address 4.
_______________________________________
(The Utah computer uses the TENEX Operating System, and is similar to
the system at BBN. The password for Network users will be:
THISISANINTENTIONALLYLONGPASSWORD
As yet, their logger is unavailable, and we have been unable to login
on their system hence, no scenario script is provided.)
BBN PDP-10 (A) TENEX Network address 69
_______________________________________
TENEX is best used in character-at-a-time mode with remote echo.
However, as TENEX treats network users as half-duplex by default, you
should either change your mode to FULLDUPLEX, or escape into NETWRK
and request local echo. At command level TENEX does not distinguish
between upper and lower case alphabetics. The programs "DOCTOR" and
"LIFE" may not be available to you in the BBN PDP-10(A) system, but
can still be used from the BBN PDP-10(B) system.

_________________________________________
The BBN PDP-10(B) is an experimental TENEX system similar to the BBN
PDP-10(A) TENEX system (network address 69.). Because of the
similarities of the two TENEX systems, no scenario is given here.
Please refer to the BBN PDP-10(A) system (page12) for the scenario.
The account number to be used for the system is "1" instead of the
"site name" used in the BBN PDP-10(A) system.
