ARPANET HOPPING: AMERICA S NEWEST PASTIME

VOLUME ONE NUMBER SIX

WUkARPANcfi

ARPANct (Advanced Research Projects Agency Network) has been
. around since the 1060s. Its intentions were to link many computers
toother in order to share resources. The various research projects oil
ARP ANct involve both major universities, and the United States mil-
itary (the t wo ait closer than cither would care to admit).

Up until last year, ARPANet was one big happy family of military and
University computers. Then, in view of War (Swkj, etc.. It was decided
that perhaps the military would be better off on their own separate
network, And so, MlLNFT was established-

This proved to be very convenient for hackers, since they now knew
where all of the military computers were— ail it took access to
M JLN ET in order to play with them.

Since A R PA Net can communicate with MILNET and vice versa* all
kinds of interesting possibilities exist. Elaborate routing makes it easy
fora hacker to cover his trail, intnuchtk'sameviiy that a phreak routes
calls through three different longdistance companies to protect hi sf her
identity.

Where can dialups to ARPANct be found? .All over the place. For One
thing, many numbers are in circulation among hackers. For another,
they're not considered all that much of a secret, since the numbers by
themselves don't allow you to logon.

If you know of a major univcrsily computer, there’s a chance that its
already hooked into the ARPANel. If this is the case, HELP files will be
readily available or that system to explain how to access the network.

The network itself is an entire world waiting to be explored. Ironically „
many sensitive computers that are “not accessible by phone lines’' are
accessible by ARPANct 1 There are a lot of lessons that still must be
learned, it seems.

50 Staple A Child Could Dolt

Moving around ARPANel is very easy as almost any backer that
used it will atce.it to. It was designed upon the principle that people on
One system should have easy access to other systems. "Easy” is the key
word here. If a direct ARPANct dialup is being used, there shouldn’t be
any problem. IfaMILNBT dialup is being used, you will need a TAC1D,
which is a private authorization code.

The woid ARPANct is used to denote alt networks. There are many
networks (see 2600. May I WML but all can be accessed as one through
“gateways" which are basically windows into other networks.

How If Wort*

There are two basic commands that can be used on the ARPANeL
“@o" and ^c". "0o" opens a connection with a host. (For example,
@o 26,0,0.1 will connect you with a host hooked to ARPANet —
indicated by the 26.) Finding addresses is really the only hard part. At
one time, a few systems had a HOST command that Would give you a
complete listing of hosts, and their addresses. In fact, this command is
still on many systems but what was unique here was the fad that you
could ran the program without fagging inf! Apparently, they got wise to
hackers* and. fixed HOST so that it only works from logged in accounts,

After typing “*@a'\ the network will respond with “Open” or, if the
attempt was less than successful* a self-explanatory error message such
as “Bad '‘or “Destination host dead*. When you gel the “Open" message*
that means you are now connected to the host computer and you can do
whatever you want, like login, read help files, etc, Communication with
the network is not cut off* however. The network is always there, waiting
to be spoken to. Commands to the network must begin. with For
example, type "i@c" when you want to close the connection with wha-
tever computer you hooked into. This will probably take a moment or
two, since the network has to close up a few things before it can transfer
control back to you, ( I ncidcntally, if you need to send a command to the
remote host that con ta ins n in it, simply type an extra next to the

first one and ARPANet will ignore it.)

Sdntt Safely Tip* and Interesting Program*

If you can dialup to a host that is connected to ARPANet* and you
have an account on it, this is ideal. There is a good chance that the host
will support a terminal simulation program* that when supplied the host
name that you wish to communicate with, will conned you to it through
ARPANet. It will then seem as if you’re on a teiminal connected to that
remote host. To close the correction* you will have to read the documav
tat ion on the host that you dialed up to, since it changes from system to
system. Naturally, using a local dialup to access a host instead of going
through a MILNET or ARPANel dialup is much "safer* 1 * since you are
not accessing ARPANet directly.

Another feature of ARPANet is the FINGER command available on
most TOPS-2D systems, and many other types as well. The FINGER
Command will provide you with a listing of people currently logged into
the system, with some information on them, such as their full name,
where their terminal is located, and what their account is known as. You
will also show up on a FINGER, and it will show whether you're on a
remote host or not. FINGER followed by a valid account on that system
will give you same ve/rdetailed info on that person. One other very nice
feature of FINGER isthat youcan supply a remote host name, and get a
listing of people on another host, without connecting to tiff (For
instance, FINGER @SRI-NIC will give you a lifting of people logged
onto the Network Info Center.) Another program that gives details on
users (though not all that much) ieSYSTAT. Both can, in many cases, be
run without fogging in r and many H ELP files are also accessible without
logging in. Certain HELP files give information on login formats or list
dialup numbers.

If you have an account on a system, the chances are quite good that
that system will support FTP, which is short for File Transfer Program.
This allows you to take files from one system, and copy them tfl the
system that you Ye on. The one problem here is that you will need a valid
account to use on the system you wish to take the files from. Most (if not
all) TGPS-2Q systems support file transfers, and consequently have an
account set aside for that purpose. The account is called “ANON YM-
OLI S* and it works with any password. Some other hosts use the account
“ ANON YMOU S "as well, but they are by no means consistent. The way
file transfers work is through an FTP on the system that you Ye presently
on. This program communkaies through ARPANet with the host you
want to take files from. On the remote host, there will be a program
running that will take requests from other hosts, and transmit files
through the network to thou. You can do more than take files, though.
You can transmit files from the host you are on to the remote host, or
delete or rename files bn the remote host, or get a directory of an account
on the remote host. It’s very handy to get a file from SRTN1C which
contains all network base addresses, addresses of gateways (ways of
getting from one network to another), and addresses of all hosts on all
networks.

And, of course* there’s the ARPANet mail system, which allows you
to co mmunicate with any ARPANet user. It works in a similar fashion to
FTP and FINGER as far as roaming the network to find * matching
username or host IP. It is Still said that there is a very active hacker
community living in ARPANet mailboxes and it ha nJ ty seems surprising
when considering how fast and efficiently this mail system works.

The Future

Since ARPANet was designed to be, and is still being used by people
who are not very familiar with computers, it will always be easy to use
ARPANet* and "hop" about it. lt^ very unlikely that they will change it
in any way, since it is, for the most pan, pretty good at keeping hackers
away from things that they're not supposed to be looking at.

Maybe...

Electronic Switching Advances

DESPITE OBVIOUS DRAWBACKS, ESS HAS QUITE A FtW NICE FEATURES

Although most phreaks tend to look upon Electronic
Switching Systems with loathing and dread* they ate ad-
mittedly fascinating animals to study. The smooth sophis-
tication of an ESS office* small machines purring away in
contrast to the deafening din of step or crossbar offices, the
conspicuous lack of relays* the presence of software,, the calm,
controlled, atmosphere. *

Horrible, isn't it? Yes, quite, but still anyone who claims to be
interested in phones must learn as much as possible about ESS,
So this is a rundown of some of the interesting things that ESS
can do.

Here are a few things that can be done in an ESS office with
individual lines that are very difficult to arrange in crossbar
types (the phone company likes to refer to these as “classes of
treatment"): Line fixed for OUTGOING calls only. Incoming
calls are thrown to an intercept operator or recording. Line
fixed for INCOMING calls wily. Battery but no dial tone if
receiver is lifted on phone , Line fixed for outgoing LOCAL
cath only- Attempts to call the operator rejected* as are calls
with zero or one as the first digit. Line fixed for outgoing
LONG DISTANCE only. Zero ororite must be first digit dialed.
Line fixed for COLLECT calling only. Paid calls rejected, as
are 3rd number or credit card billings, (Used in prisons* jails,
and other controlled situations,) On these* rero is the only
acceptable first digit to dial. Line fixed for OUTGOING
CALLS REQUIRE 1TL (what used to be a “Q" number in
manual handling situat ions) Dial your call and enter a 4-6 digit
personal code . ( Large companies make use of this to keep track
of their employees’ calls.)

[t^ said that there arc about fifty classes of treatment, with
class I being totally unrestricted (Le* a “normal" line). As the
numbers progress the types of specialties change. About 20
“classes" are available* the remaining 30 or so are merely
various combinations of the first 20 (outgoing calls only and no
long distance calls allowed, eicfi. Around 85 percent of the
phone lines are just your average normal arrangement — the
other 15 percent are very esoteric arrangements for super-large
companies, institutions, government* etc.

Some other classes of treatment that are no problem for ESS
to arrange are: Decline to -accept operator assisted calls. The
operator is unable to intercept the line to test for busy or to
interrupt in case of an emergency This feature shows up a lot
on modem lines, since as many have found out, an operator
cutting in on data transmission will frequently wind up
inadvertently disconnecting the modem Hotel/motel service.
A guest dials his; her calls normally, butTSPS will come on line
to take the room number or credit card number without having
to dial zero phis. TSPS sends the charges cm “paid "calls back to
the hotel via a private line to either a Teletype machine or'
billing equipment on the hotel premises. Automatic reverse
charge Accepted. This is your “800" service. Under ESS, it^s
possible to simply take an ordinary line (a regular seven digit
phone number) and assign an “800“ billing code to it. Coin
service. This is your traditional “pay phone" but in a new
arrangement. Instead of a coin hitting a lever which makes the
tip go to ground for a half second (ground start line), the ESS
gives “dial tone first" and instead of the five cent “ding" and the
ten cent “ding ding”and the twenty five cent “doqg”as the coins
are deposited* the coins being deposited make certain fre-
quencies on the line. ESS is told from a phone in this “class of

treatment" to expect these frequencies, etc.

The Touch tone Problem

As most phreaks already know* if a central office is set up for
rouchtone service, then every line is set up for same. Ail one has
to do to obtain touchtone service is liberate a touchtone phone
someplace. If the tones don't sound when theyVe pressed* then
the tip and ring are most likely reversed. Change the position of
the red/ green (yellow/ black) wires and the problem should
stop. But in ESS offices* you can foiget it! !

In an ESS office, when you lift the receiver to make a call*
you are extended one of two types of line selectors. The one is
for customers who ha veptfiY/for touchtone service. The other is
for customers who are listed as having rotary service. Oddly
enough, when you reverse the tip; ring, you wont ^t the
tones — place them properly and you wifi get the tones — but—
touchtones won) cut the dial tone in an ESS office unless
you’ve paid for it!

This feature always causes huge problems whenever an office
is cut over to ESS, For various reasons, the phone company^
outside plant records are usually a complete shambles* They
tend to keep very poor records about just what is on the
subscribers' premises. So what usually happens is this: a big
company that has their own centre* line opens Its doors on
Monday morning (most ESS cut-overs take place on Sunday
mornings to lessen the effect of any interruption in service) and
finds that half of its touchtone phones don't work! The phone
company records didn't say to set up those particular lines with
touchtone! Everyone has fun.

Let’s Be Fair . ^

For dedicated phreaks, ESS poses a number of serious
problems. But, at the same time, an awful lot of new features
(i,c. toys) are making their way in our direction, thanks to ESS.
The increased ease in call supervision is one feature you don't
hear much about from the phone company and one that many
of us would prefer to do without. But there art these “good"
things .that the telco uses as a selling point in ESS — how
beneficial these are to you, versus the obvious disadvantages*
you'll have to decide (even though it won^ change a thing).

Call Forwarding: Forward incoming calls to whatever phone
you want, local or longdistance. Call Waiting A tone comes on
the line to let you know that another call is trying to reach you
while you're using the phone. Three Way CaJHngi Use the
switchhook to bold one party while bringing a third party on
the line. ConudUtun Calking: Like three way, but you converse
privately with a third person* hangup and get the first one back
who had been waiting on hold* Speed .Calling: Allows calls
anywhere in the U ,5, orGanada by dialing just one digit and the
star sign. Store and Forward: If you can't reach your party, you
can dictate a voice message to the ESS computer. Tell the
computer to try every fifteen minutes until the party answers,
then deliver your recorded message to him. Answering Service:
Like a phone answering machine* but it is in the computer! Dial
a special code, dictate your “answering service" message and
hang up. If you don\ answer after a set number of rings* the
computer will play your recording and take a message from the
caller!

Phone companies all over are finding that these “enhanced
feature$“ are big sellers* In future issues, well discuss some of
the bugs that have been found in these features* and in ESS
systems in general.

Sophisticated as it may seem, ESS is by no means perfect-

No More Free Info

2600

In a move that caught almost everyone off guard, AT&T
quietly put an end to the age-old tradition of five directory
assistance. As of the end of May* it now costs 50c for each call
to long distance information (XXX-555-1212) within the
United States. And unlike previous instances of local telephone
companies charging for directory assistance, there is no way to
avoid this by using a public phone! Information costs 50c from
everywhere with these exceptions: local directory assistance,
which is st ill controlled by the local companies and not AT&T ;
S00& 900 info; Canadian. info: and overseas info. AT&T is also
generous enough to allow you two free calls to king distance
info per month, providing you make at least two longdistance
calls per month, (No, other calls to information don't count as
long distance calls T)

Reaction to this change ranged from total ignorance to
complete disbelief. An AT&T operator told us^We didn't even
know about this until today! [the day it went into effect] I don't
understand these people— they're going to lose a lot of cus-
tomers by doing this. What they should do is charge only the
people who aren’t using AT&T as their primary carrier. Then,
we can advertise “free directory assistance" which no other
company cam*

As it happens, other companies such as Skyline now allow
customers to dial long d istance information on their networks.
The calls are billed as if they were tegular calls to that area.
Since calls to directory assistance generally last less than thirty
^ seconds, the charge winds up being less (sometimes signi-
ficantly) than 5Qe. If you choose this way to call information,
you may be lucky enough to hear one of the info operators say,
“Thank you for dialing ATAT.” You can then have a good
laugh at their expense.

Meanwhile, phone phreaks around the country were parti-
cularly indignant. "This puts a real crimp on silver boxipg," one
said. “And Elm sure our favorite corporations wont enjoy
paying for our information calls now on top of all the other
ones," Others have suggested ordering as many free telephone
books as possible, and distributing them around the country or
actually setting up an alternate directory assistance center. Free
telephone books can usually be obtained through local phone
companies.

Computer Threat Causes Chaos in Albany*^,,

AhkiihI Ph

Federal and local officials were baffled by a message which
appeared on a computer terminal May 19 at Albany County
Airport in Albany, New York. The message said that armed
individuals would be boarding a plane, according to the FBI.

At about 7:15 am, the message was found on a computer
screen at Boarding Gate 3. It warned that if anyone tried to
interfere, “people would die, 1 ' Security personnel searched a
plane that was coming in at that gate, but found nothing.

The FBI and local authorities are trying to determine if the
message was left by an airport employee or by an outsider who
somehow broke into the computer system.

E-COM Is Going Away

tartritbri F*tW

The Board of Governors of the Postal Service has voted to
get out of the computer mail business and possibly turn it over
to a private contractor .

E-COM is what the Postal Service calls its computer mail
operation, short for Electronic Computer Originated Mail. The
system was designed for mass mailers, but never met its
expectations since it began in January, 1982, The chief users of
the system had been financial institutions, retailers, airlines,
and hospitals.

AT&T Limits Use of Their Credit Cards

(YrtifMnpl NcwlShimcl .

AT&T is in the process of barring d inect-dial credit card calls
from south Florida to 26 countries. The nations include most of
Central and South America, some in the Caribbean and some
in Asia, including Israel.

“The countries selected for the suspension of credit card calls
are places to which a majority of international fraudulent calls
are being made," said Barry Johnson, an AT&T spokesman
The Israeli prime minister was unavailable for comment.

FCC Actions

H|tv£

The Federal Communications Commission has ruled that

operators of the so-called “dial-a-pom” phone services must
restrict children’s access by limiting hours of operation to after
the sun has gone down. Under the ruling, whichgoes into effect
on July 12, tape-recorded messages will be restricted to between
9 pm and 8 am. Live services will still be available on a 24-hour
basis, however. They usually require a credit card number.

The FCC has voted to usea lottery to select three "network

organizers" who would be responsible for constructing nation-
wide paging services. Such systems would allow a New York
businessman traveling in California to be "beeped "by his home
office (or anyone else who knew how to tap into the system).

The organizers will construct a long-distance transmission
system using either satellite or telephone facilities to link local
paging companies across the country. They will also oversee the
use of one of the three special frequencies that have been set
aside by the FCC to transmit the paging signals.

Over the protests of MCI and GTE Sprint* the FCC has —

decided to allow AT&T to immediately begin a service that seir^ *
a flat monthly rate for an hour's worth of long-distance ca v f*

Under this new option* customers can pay $ IQ a month fotar*^
hourly worth of calling time each month for direct-dialed
domestic calls placed during night rate periods. Wow.

"it Anu lAAbiL aiiiiL UJ IHL bKMi HKIAK-Lr

i have had it up to hen with this divestiture cmp! 1 consider
myself to be a very loyal phone phreak who has always hated
Ma Bell with a passion. What I wouldn't give to have the good
old days back, when Bell was the only game in town!

Now there’s this strange entity called AT&T Communi-
cations. I still don’t know where it is they're coming from.
They’re not my local company. They're my long distance
company that I never asked for, My local company (not
AT&T]} decided to tell my long distance company that 1
wanted a special service that allowed me to make kits of long
distance calls within my state for a discount. 1 didn't object at
first. But then I saw myselfgetting charged a minimum fee every
month 1 didn't use it! Who do 1 complain to? My local
company? AT&T They, both blamed each other. Finally,
AT&T said they'd fix it, but they never did, Now who do i
complain to? The Public Service Commission in my state
doesnlt handle national telephone companies — only statewide
ones. The business office ladies of my local company are very
happy to listen to my complaints and are even happier to say,
“That's AT&T, not us. We’re not the same company anymore."

My local operator, for some reason, seems to be a part of
AT&T, if 1 call to tel] her that my house is burning, i fully
expect to hear her say that 1 have to call my local telephone
company and please leave AT&T out of it.

We never should have been allowed to get hooked on the Bell
system— that^ what spoiled us. Equal access from the be-
ginning would have made sense. To have it suddenly start now
is one big fat pain!

It^ the government that’s to blame, really— they're the ones
that have screwed things up so badly. No one knows from one
minute to the next how they're going to dial a number. First,
they say we Ye going to dial 950-I0XX for every long distance
call. Then they say we’re going to skip the 950 part andjustdial
I0XX pins the number. Now they're telling us that we’re going

to have to subscribe in advance to MCI, Sprint, etc. Meanwhile
all of these long distance companies are popping up out of
nowhere with advertising blitzes that make you feel like an idiot
for not signing up right away. Ail it’s doing is confusing the hell
out of older people and people who aren't too bright os wctlw
those who just aren’t phone ph teaks. My parents cant keep up
from one minute to the next and Ilm not much better off,
despite my knowledge of the system I

The way 1 see it, this divestiture is goiqg to cause all the
smaller companies to give poorer service and go up on their
rates even more. (Soon I won It be able to afford to call people
unless they're long distance — local rates just keep climbing?)
Local companies are letting their exchanges fall apart. They
claim they're going to have to raise their rates to pay for
maintaining the CCX V Service has gone downhill — even worse
than it ever was. The whole thing is a mess.

Think of how easy it used to be. it was you and the phone
company. The phone company provided your phone, fixed
your phone, gave you local calls, longdistance calls, operators,
free directory assistance. If you were a phone phreak, you had
to worry about the phone company. T oday, a phreak has to
worry about so many different companies itli make his
head swim!

The old days will never come back, 1 guess. But let^ try to
remember them this way things were horribly unfair and
dictatorial. But at least everything worked. The phone com-
pany took pride in its work instead of shifting the blame to
another phone company. It was easy to complain, easy to get
repair service to your door, easy to figure out if you could
afford to make a call. The instruments lasted forever— -in fact,
my phones from the forties and fifties are in much better shape
than the new crap l have!

Today things are fair and equal, or getting there. 1, for one,

can really see the difference.

LETTERS FROM OUR READERS

5/28/54

Dear 2601k

This is Quasi Moto T SysOp of the late Plover-Net Bulletin
Board System (BBS). 1 am writing this letter to try to explain to
all of you just what really happened to Plover-Net.

1 guess the main reason that 1 took the system down was that
[ could only take so muchofallof it. What exactly do 1 mean by
“all of it 1 ? Well, first and foremost, it's not easy going to bed
every night thinking, “Will the Feds call tonight? Will my BBS
be crashed by some hacker with nothing better to do?" and so
forth, And then 1 awaken at 4:40 am to the annoying sound of
the Rana recalibrating. Since I'm up, might as well validate
users* etc. I notice that “TSyntax Error” is on the board, yawn
and snicker as J smash the RESET key and the modem gives a
sharp dick as it disconnects that loser from the BBS.

The BBS re-runs itself and I logon. The first new user is
“Fuck You” from “Your, asshole". 3 users later it’s “Rachal
Amato"(the name CN/ A has for the BBS line). And then there
are 2 messages with I/O errors in them which 1 must delete,
despite the fact that the Rana is full at 202 messages and I must
delete the first 5-10 (which takes on the order of 5-10 minutes).
Then l get to take a shower and get dressed before school!

But 1 guess the real reason 1 took Plover-Net down was
money, The phone bill, on the order of £50 or more a month
was defrayed by about S 15-20 per month. Which left me with
about £30 every month to pay from my own pocket! This
-doesnlt even touch the electricity it draws or all the software
updates. That is when 1 put a stop to it.

1 would like to stress the point that Plover-Net was not, 1
repeat, not busted , or for that matter, eve r contacted by any law
enforcement agency, 1 look it down of my own free will, 1 would
like to take this final opportunity to give a piece of advice to all

you other phreak SysOps . . .stay cool and put up my disclaimer.
It s the “perfect "disclaimer, if you need a copy, or need to get in
touch with me urgently, write to Quasi Moto c/o 2600
Magazine,

Dear

Your article on step switching was super informative. Now I
have a question, l found a really strange telephone switching
center, 1|Y 518-789, Can you tell me what type it is? It is so
strange when you call it you can hear it dialing the number. And
it starts ringing and you can still hear it dialing! It is crazy!
What is it?

Awfully Curious

Dear AC:

518-789 is a very, very small (XY) step by step switching
center. And if it Y like most of them, it could be in a trailer ora
very small building. It could even be in a house where the
owners can keep a close tab on it. A test number for this
exchange is 5 J 87893299.

The dialing sound you described is fairly common with step
offices. We Ye dealing with an independent phone company toll
center here - it only does what it's told to do. The to LI switcher is
dialing a complete 7 digit number. Now, Western Electric
doesnlt allow you to hear pulses. When you dial into a step,
though, different roles sometimes apply. If, for example, you
dial 5 1 87892000, it will immediately start ringing after the 7892
because there is no 7892 group. But it will dial the three zeroes
after the two anyway, and you can hear that on top of the ring,
(if you hove a question about a. particular telephone exchange
or a comment about phones and/ or computers* send it to us at:
2600, Box 752. Middle Island i. NY 11953. Anonymous letters
accepted cheerfully !)
