JANET (the Joint Academic NETwork) is a favourite hacking tool for newcomers to
hacking - mainly because it and the computers attached to it offer you so much
help and information which can be used to do nice things with their micros!
Hey ho and here we go!
The first thing that you need to do is to find a telephone access number for
the JANET pad nearest to you. To help you do this please refer to file #6, in
this issue of H-Net which is Hackernet BBS's latest list of such numbers and in
some cases gives the baud rates which have been tested out on these pads.
When you have found the telephone number that you need then set your comms
terminal to seven bits, even parity with one stop bit (7e1). Then dial the
telephone number (a baudrate of 2400 is sometimes catered for - but is
unreliable on some pads). When you get the CONNECT message press your <RETURN>
key a couple of times, if nothing happens then wait about 4 seconds then press
the <RETURN> key two or three times again. You should now get a 'welcome'
message (on some PADS you might now get the prompt 'Which Service?' type 'PAD'
<RETURN>) the ypu will get a system prompt (e.g. 'PAD>'). If you do not get
such a prompt then drop the line and reconfigure your comms s/w (you might have
to do this a few times until you work out the proper settings as all pads do
not work on a uniform setting - unfortunately! - but it's all good hacking
experience anyway - trying to work out the proper settings for the target
system.
When you have the 'PAD>' or a similar prompt then type the following command:-
PAD> logon f,r
the pad isn't really all that fussy about what you use after the 'logon'
command, 'f,r' is just an example - in practise you could use anything, most
people use 'x,x' for some reasonh...please note that on some pads that you
might have to type 'login' instead of 'logon'.
What does this command do? Well it tells the JANET Pad that when you have
called through to one of the computers connected to it's network - done your
business then exited from that computer that you want to return to the 'PAD>'
prompt so that you can 'CALL' other computers on the network. If you do not
enter this command your line will be dropped when you have exited from the
first computer on the network that you have called - and that would mean having
to redial the pad again....yawn!
The next command to get to grips with is the 'CALL' command. This along with a
NETWORK ADDRESS allows you to connect to other computers on the JANET network.
In file #7 in this issue of H-Net you will find a list of some of the computers
that you can connect to on the JANET network along with their NETWORK address
and/or their NETWORK mnemonic.
The way to use the 'CALL' command is as follows :- firstly, find the NETWORK
ADDRESS of the computer that you wish to connect to (in this example the
Unaxcess chatboard at Bradford University which is 0000121100 ), then type the
following at the 'PAD>' prompt :-
PAD> call j.0000121100
The 'j.' just tells the pad to expect a JANET address. Please note that some
PAD managers have gotten wise to hackers using their PADs to gain access to
systems on the JANET network, in these cases they might have changed the format
of the 'CALL' command around a little bit - usually by making it so that the
'.' after the 'j' in the above example is no longer required - on such systems
the 'CALL' command should be :-
PAD> call j0000121100
On some PADs there is on online help facility - to make use of this just type:-
PAD> help
you should get a response similar to this :-
Help knows about :-
ADDRESS TARIFFS STATUS
The address helpfile is usually quite useful - to get this type :-
PAD> help address
then a nice list of network mnemonics available from that PAD might start
scrolling down your screen. Mnemonics can be used instead of the NETWORK
ADDRESSES previously mentioned. For instance if we wanted to call the
Lancaster Universities' PD software computer system use the following call
command :-
PAD> call lancs.pdsoft
It is just a nice way to be able to access the systems on the network as they
cannot expect the average student or lecturer to remember the 10 or 14 digit
NETWORK ADDRESSES which prevail on the JANET system!
When you have entered your 'CALL' command you should get a response such as
'connecting..' if you just get garbage then you might need to change the
configuration of your terminal. For instance if you call the pad using 7e1
then when you call an address and just get garbage then quickly switch to 8n1
and press return once - you should then get some sense out of the computer that
you have requested access to (usually a 'login:' or similar prompt). If this
does not work then keep on changing your settings until you do get in.
From here on in it will be just like calling the target computer direct, except
that when you exit from the computer you will be returned to the 'PAD>' prompt
again (if you remembered to enter your 'logon' command!), again - if you just
get garbage after terminating your session on a computer on the JANET network
then you will need to reset the configuration of your comms s/w / terminal to
what it originally was when you first called the PAD.
Well, that just about sums it up I guess - this should be all you need to know
about using the JANET system and pads - the little quirks it has and so on. The
best thing about JANET in my eyes is that (usually for the price of a local
call) you can get into computers all over the world, belonging to mainly
educational establishments but also defence and other organisations! The main
type of computers that you will find on JANET are VAX, UNIX and PRIME with a
splattering of other systems here and there.
I hope that this file has been of help to you - if you have any new information
about JANET in general or some of the systems available through it then please
e-mail me 'WEAZLE' on the Hackernet BBS.
