Logging in and out is covered in the first chapter of the UNIX text, but
this assumes that you are sitting in front of a terminal that is
connected directly to the UNIX machine.  Most of the terminals on
campus are connected to a terminal server, from which you can reach a variety of
machines.  Thus, if you are on campus, you need to know how to talk to
the terminal server.  Carriage returns should produce a 'SDSUNET>' prompt;
in this case, you simply type
c ucselx
(and a carriage return, of course)
ucselx is the name of one of the campus Elxsi 6400, which will be your home for
this course.  If the Elxsi is actually up, and there is a free port, and
the phases of the moon are just right, this will get you the login prompt,
perhaps after a few more carriage returns.

If you are calling campus from elsewhere, you first need to establish
a connection between your modem and the campus modems.  Dial 594-7700
using your 300-, 1200-, or 2400-baud modem.  Repeated carriage returns
should produce the '#' prompt, and you can proceed with "c ucselx".

You should have the login: prompt
If the "c ucselx" command succeeds, you should see something like:
ELXSI 4.3 BSD UNIX (ucselx) (ttyxx)

login:

Now type:
maxc0ddd
(where ddd represents the digits that make up your unique username.
These digits, along with your current password, will be assigned to you in class.)
Don't forget to end your entry with a carriage return.
After entering your password, you will get some messages and the query:
TERM = (vt100)
Entering only a carriage return will set your session up for use with a
vt100-compatible terminal; if you are not CERTAIN you are using a vt100
terminal, enter:
dumb
just to be on the safe side (don't forget to also enter a carriage return).
Later, we can investigate what the proper setting for your particular
situation should be.  Most campus terminals are vt100, though there are some
Telerays, for which you should enter t10.  Common codes for terminals you
might use from work or home include sun (for Suns), hp150 (for Hewlett-Packard),
and xterm (for Xwindow applications).  If you are using a home computer with
a terminal emulator, it usually will emulate a vt100.

After this, you will see your standard prompt, which will look like:
maxc0ddd:maxc0ddd[51]%
Your prompt will change as you work, and the significance of this
information will be discussed later.

Your first task is to change your account password.  Do not choose
something obvious, or even a word in the dictionary, or your account
is going to be broken into.  Reasonable choices include sequences which
include a non-letter (but don't just put a digit on the end of a word,
as this is easily guessed).  You will lose an assignment's worth of
points if at some point in the semester you use a dumb password (or if
you continue to use the password that has been originally assigned to
your account).  Enter
passwd
and then answer the questions - for security reasons, what you type will
not appear on the screen.

Next, experiment with the finger command by typing
finger $user
to see your own information.  Compare this to mine:
finger carroll
Now use
passwd -f
to update your finger entry.  You may wish to leave some of the fields
blank, but for this assignment, you must place a proper entry in the Name
field.  You can view your results with
finger maxc0ddd

The entire set of UNIX manuals is on-line, available through the 'man' command.  Type:
man finger
to see the entry for finger.  To find useful information when you are not
sure of the command name, use apropos:
apropos printer
...will give you a list of man entries pertaining to the printer
(specifically, it displays those entries with the character sequence 'printer'
somewhere in the command summary line.

You will find a file called 'assignment1' in the home directory of your account;
it contains this text. You can make copies of this file and otherwise
practice the commands described on page 39 of the Wang text.

Extra copies of campus-specific information, such as the handout
"How to use BSD UNIX on the Elxsi", are available in BAM110.

Technical Junk:
To configure your home modem and terminal or micro, you need to set the
communications parameters for your RS-232 interface to: 300, 1200, or 2400 baud
None or Even parity, Full duplex, 1 start bit, 8 data bits, 1 or 2 stop bits
