An overview of the x25 network we all know and love, datapac.

by lxl for 9x [o9/2o/98]

Greets to everyone in 514. What i'm going to try to do is give some 
information about Datapac and it's features.This file is based on 
my explorations,and info gathered from numerous other sources.

______________________________________________________________________
                          
                          [ INTRODUCTION ]

   Datapac is a Canada-wide,public packet switching network.The network is    
call based,providing virtual circuits between subscriber terminals.These    
virtual circuits allow data communication between devices across the country
or around the world.

  In my opinion,Datapac is a great place to explore,you have a wide array
of systems such as unixes,vax/vms,HP-3000, at your diposal.Basically you
just find the dialup in your city and connect to the system,but if you want
to really see everything on Datapac,you need an NUI.If you don't have one,
you only have access to a small number of NUA's.If you don't have one you can
still get by,but NUI's are very helpful,they are like calling cards on the
network,they provide your access to almost any address.If you still want to
access all the adresses it's not so easy,most sites do not accept collect calls.
You can either find sites that do accept remote charging(destination charged
for the call),or get your self a NUI(Network User Identifier).The latter
is the more difficult,obviously.

  Well there are still a lot of things you can do without a NUI,I will cover
the whole process of connecting to the system and giving you some advice on
how to get more familiar with the system.Hacking in my opinion is about 
learning on your own and discovering new things,this file is just an 
introduction,something to get you started.
___________________________________________________________________________

                      [ ACCESSING DATAPAC ]

   All you have to do to connect to Dpac is to find your local dialup.
This is very easy and should not be a problem for any of you guys.
If you can't find,just ask around or call the Datapac customer service #.

  Once you have your local dialup,you connect to the system and enter 
three periods ( ... ) and press return.

   This establishes a physical connection to the network.At this point
Datapac will determine parity and speed applicable to your terminal.

  Datapac will then identify itself by giving you the network adress of
the port you are connected to,and wait for your request.
    
It should look like this    

                  DATAPAC: XXXX XXXX
 
  You are now ready to enter an NUA (Network User Adress).*Remember you can
only connect to sites that accept collect calls,unless you have a NUI*.

   A NUA is the most important thing,it is the adress of the machine you
want to connect to.Basically an NUA consists of an 8-10 digit number,all
you have to do is type it and press <return>.Datapac will answer with a 
message indicating  if you have succesfully connected.

  example:   92100086 <return>
     
   Datapac:call connected to 9210 0086      
   (001)(n,remote charging,packet size:256)

 This tell's you that you have succesfully connected,the set of brackets 
contains additional info about the connection.

              001 - logical channel used for the call 
                n - normal traffic class as opposed to priority call 
  remote charging - the destination is charged for the call 
  packet size:256 - the packet size for the call was 256 characters

*note*,the Dpac Information system is a great place to get all the extra info
you need,everything is explained in details in case you need additional info.

  Most of the nua's you encounter will usually answer with

        "DATAPAC : call cleared - adress not in service "
                          
                             or

        "DATAPAC : call cleared - access denied 

 These seem to be the most common messages,but you will encounter other's,
All listings of error messages can be found in the Dpac Info System.

    The best way to find good NUA's is to scan,there are scanner's out there
but they aren't always easy to come by.You could always write your own if 
you do code,or if you don't,try learning to make one.

____________________________________________________________________________

                   [ Datapac International Access ]

   Calls to international networks,with the exception of the U.S networks
(listed bellow) *must* be pre-paid,that is,placed from dedicated access,
private dial,or public dial with a NUI.

  You can reach these networks without a NUI:

 Accunet              Bell Atlantic
 Nynex                U.S West
 Autonet              B.T Tymnet
 Fedex                Net Express
 Bell South           Centel
 Sprintnet

 In order to connect to one of these networks,you must follow the correct
procedures.

   1 - enter a prefix ( "1" identifies to Dpac that you are making an
                       international call )

   2- enter a DNIC (Data Network Identification Code)
                    *similar to an area code used on the public telephone
                     network,Datapac's DNIC is 3020*
                    
   3- enter the NUA

    
            format :  (1) (DNIC)  (FOREIGN ADDRESS)
                       :     :            :
Dpac International ....:     :            :
    Prefix                   :            :
                             :            :
Packet networks are..........:            :
identified by DNIC's                      :
                                          :
address (8-10 digit's)....................:

    
So let's say you want to connect to an adress on the Tymnet network.  
You would type:           " Tymnet"
 
                13106xxxxxxxxxx <enter>


                          "sprintnet"

                13110xxxxxxxxxx <enter>

                        "At&T Accunet"

                13134xxxxxxxxxx <enter>

                        "Western Union"

                13114xxxxxxxxxx <enter>

 All you have to do is get a list of DNIC's and your set,one can be found on
the good old Dpac Information system.

  You now should be able to navigate through the network rather easily.There 
are still many commands i have left out and some features.These subjects are
a little bit more indepth and are not useful until one has the basic's 
covered.

                           < OUTDIAL 's >

   Outdial's are modem's connected to datapac that customer's can use to
dial a local phone number.There are a lot of outdial's on Dpac,the *majority*
of them require a NUI and usually are no higher than 300,1200 or 2400 bps.
You can get lucky and find one without a password and global dial,but they 
are very hard to come by.There are also various systems that let you dial
out on their modem's,i have yet to encounter one,but i have heard they exist.

  Outdial's are a great way to "disguise" the location of your call,they
are a hacker's friend,especially these days when finding PBX's isn't so 
easy and carries considerable risk,especially with ANI.

                          < SOME HELPFUL TIPS >

    You will encounter many system's on Dpac,many of them require passwords
to get into.Some do not and will just let you look around.You should
not cause any damage to *any* system you enter.Hacking in my opinion is 
not about spreading viruses and locking people out of their accounts,it is
about learning,a love for technology.The media has painted a harsh image of
the hacker,the truth seems to be clouded,but that's just a part of society.
The new generation of computer junkies must respect their machines,and not
beleive the bullshit in the movies.Good luck to all who are exploring 
the net's for the first time,i hope this article will get you started with 
datapac.

  Any feedback would be appreciated,i can be reached on undernet or efnet.
Seek and ye shall find ;)
