Welcome to Hacking DEC'S.  In this article you
will learn how to log in to DEC'S, logging out
and all the fun stuff to do in-between.  All of
this information is based on a standard DEC
system.  Since there are DEC systems 10 and 20, &
we favor the DEC 20, there will be more info on
them in this article.  It just so happens that the
DEC 20 is also the more common of the two, and is
used by much more interesting people (if you know
what we mean...)
Ok, the first thing you want to do when you are
recieving carrier from a DEC system is to find
out the format of login names.  You can do this by
looking at who is on the system.
DEC=> @  (the 'exec' level prompt) YOU=> SY
SY is short for SY(STAT) and shows you the system
status.  You should see the format of login names
... A SYSTAT usually comes up in this form:

JOB LINE PROGRAM NUMBER

Job: The JOB number (Not important unless you want
to log them off later)
Line: What line they are on (used to talk to them
...) (These are both two or three digit numbers.)
Program: What program are they running under?  If
it says 'EXEC' they aren't doing anything at
all...
User: ahhhAHHHH!  This is the user name they are
logged in under...  Copy the format, and hack
yourself out a working code...
Login format is as such:
DEC=> @
YOU=> login username password
Username is the username in the format you saw
above in the SYSTAT.  After you hit the space bar
after your username, it will stop echoing
characters back to your screen.  This is the
password you are typing in...  Remember, people
usually use their name, their dog's name, the name
of a favorite character in a book, or something
like this.  A few clever people have it set to a
key cluster (qwerty or asdfg).  PW's can be from 1
to 8 characters long, anything after that is
ignored.

You are finally in...


It would be nice to have a little help, wouldn't
it?  Just type a ? or the word HELP, and it will
give you a whole list of topics...  Some handy
characters for you to know would be the control
keys, wouldn't it?  Backspace on a DEC 20 is rub
which is 255 on your ASCII chart.  On the DEC 10
it is CTRL-H.  To abort a long listing or a
program, CTRL-C works fine.  Use CTRL-O to stop
long output to the terminal.  This is handy when
playing a game, but you don't want to CTRL-C out.
CTRL-T for the time.  CTRL-U will kill the whole
line you are typing at the moment.  You may
accidently run a program where the only way out is
a CTRL-X, so keep that in reserve.  CTRL-S to stop
listing, CTRL-Q to continue on both systems.
Is your terminal having trouble??  Like, it pauses
for no reason, or it doesn't backspace right?

This is because both systems support many
 terminals, and you haven't told it what yours is
 yet...  You are using a VT05 (Isn't that funny?  I
 thought I had an apple) so you need to tell it you
are one.
DEC=> @
YOU=> information terminal
or...  YOU=> info ter
This shows you what your terminal is set up as...
DEC=> all sorts of shit, then the @
YOU=> set to vt05
This sets your terminal type to VT05.  Now lets
see what is in the account (here after abbreviated
acct.) that you have hacked onto...
SAT=> DIR
Short for directory, it shows you what the user of
the code has saved to the disk.  There should be a
format like this:
xxxxx.ooo
xxxxx is the file name, from 1 to 20 characters
long.  ooo is the file type, one of: exe, txt,
dat, bas, cmd and a few others that are system
dependant.  Exe is a compiled program that can be
run (just by typing its name at the @).  Txt is a
text file, which you can see by typing=> type
xxxxx.txt.  Do not try to=> type xxxxx.exe  This
is very bad for your and will tell you absolutely
nothing.  Dat is data they have saved.  Bas is a
basic program, you can have it typed out for you.
Cmd is a command type file, a little too
complicated to go to into here.  TRY => take
xxxxx.cmd.  By the way, there are other users out
there who may have files you can use (Gee, why
else am I here?).
TYPE => DIR <*.*>    DEC 20
     => DIR [*,*]    DEC 10
* is a wildcard, and will allow you to access the
files on other accounts if the user has it set for
public access.  If it isn't set for public access,
then yo won't see it.  To run that program:
DEC=> @
YOU=> username program-name
Username is the directory you saw the file listed
under, and file name was what else but the file
name?

** YOU ARE NOT ALONE **

Remeber, you said (at the very start) SY  short
for SYSTAT, and how we said this showed the other
users on the system?  Well, you can talk to them,
or at least send a message to anyone you see
listed in a SYSTAT.  You can do this by:
DEC => the user list (from your systat)
YOU => talk username (DEC 20)
       send username (DEC 10)
Talk allows you and them immediate transmission of
whatever you/they type to be sent to the other.
Send only allows one message to be sent, and only
after you hit <return>.  With send, they will send
back to you, with talk you can just keep going.

By the way, you may be noticing with the talk
command that what you type is still acted upon by
the parser (control program).  To avoid the
constant error messages type either:
YOU=>  ;you message
YOU=>  rem
       your message
The semi-colon tells the parser that what follows
is just a comment.  Rem is short for 'remark' and
ignores you from then on until you type a CTRL-Z
or CTRL-C, at which point it puts you back in the
exec mode.  To break the connection from a talk
command type:
YOU=> break

PRIV'S:

If you happen to have privs, you can do all sorts
of things.  First of all, you have to activate
those privs.
YOU => enable
This gives you a $ prompt, and allows you to do
this:  Whatever you can do to your own directory
you can now do to any other directory.

To create a new acct. using your privs, just type
=>  build username.  If username is old, you can
edit it, if it is new, you can define it to be
whatever you wish.

Privacy means nothing to a user with privs.  By
the way, there are various levels of privs;
Operator, Wheel, CIA.  Wheel is the most powerful,
being that he can log in from anywhere and have
his powers.  Operators have their power because
they are at a special terminal allowing them the
privs.  CIA is short for 'Confidential Information
Access', which allows you a low level amount of
privs.  Not to worry though, since you can read
the system log file, which also has the passwords
to all the other accounts.  To de-activate your
privs, type:
YOU=> disable

When you have played your greedy little heart out,
you can finally leave the system with the command
=> logout
This logs the job you are using off the system
(there are be variants of this such as kjob, or
killjob).  By the way, you can say (if you have
privs)
=> logout username
and that kills the username's terminal.

There are many more commands, so try them out.
Just remember: Leave the account in the same state
as you found it.  This way they may never know
that you are playing leech off their acct.
