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 .Datapac will answer with a message indicating if you have succesfully connected. example: 92100086 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 "sprintnet" 13110xxxxxxxxxx "At&T Accunet" 13134xxxxxxxxxx "Western Union" 13114xxxxxxxxxx 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. ___________________________________________________________________________ < SCANS OF THE MONTH > Here are a couple of NUA's i found, enjoy. 3670 0021 3670 0033 3670 0042 3670 0053 3670 0057 3670 0063 3670 0068 3670 0082 *I will be adding another 30 or so Nua's* 3670 0101 3670 0143 3670 0188 3670 0206 3670 0209 _____________________________________________________________________________ < 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 ;) ___________________________________________________________________________ < Special Thanks > Thanks to all the people who helped(and still do) me out. www2.dope.org/9x -= Spreading HP in the new millenium
