There are literally hundreds of systems connected to some of these larger
networks, like Tymnet and Telenet.  Navigation around these networks is very
simple, and usually well explained in their on-line documentation.
Furthermore, some systems will actually tell you what is connected and how to
get to it.  In the case of Tymnet, after dialing in, at the log in prompt, type
"information" for the on-line documentation.
 
Accessing systems through networks is as simple as providing an address for it
to connect to.  The best way to learn about the addresses and how to do things
on a network is to read "A Novice's Guide to Hacking (1989 Edition)" which was
in Issue 22, File 4 of 12, Volume Two (December 23, 1988).  Some points are
re-iterated here.
 
Once on a network, you provide the NUA (network user address) of the system you
wish to connect to.  NUAs are strings of 15 digits, broken up in to 3 fields,
the NETWORK ADDRESS, the AREA PREFIX, and the DNIC.  Each field has 5 digits,
and are left padded with 0's where necessary.
 
The DNIC determines which network to take the address from.  Tymnet, for
example, is 03106. 03110 is Telenet.
 
The AREA PREFIX and NETWORK ADDRESS determine the connection point.  By
providing the address of the system that you wish to connect to, you will be
accessing it through the net... as if you were calling it directly.  Obviously,
then, this provides one more level of security for access.
 
By connecting to an outdial, you can increase again the level of security you
enjoy, by using the outdial in that area to connect to the remote system.
 
Addendum -- Accessing Tymnet Over Local Packet Networks
 
This is just another way to get that extra step and/or bypass other routes.
This table is copied from Tymnet's on-line information.  As said earlier, it's
a great resource, this on-line information!

On a side note, the recent book The Cuckoo's Egg provides some interesting
information (in the form of a story, however) on a Tymnet hacker.  Remember
that he was into BIG things, and hence he was cracked down upon.  If you keep a
low profile, networks should provide a good access method.
 
If you can find a system that is connected to the Internet that you can get on
from Tymnet, you are doing well.
