Greetings fellow CyberNauts:
|
|
|
|
This gem was downloaded from the DDN on the InterNet. It is a good
|
|
guide for learning to hack the Net. If you like what you see leave
|
|
note for Argonaut at Rivendell BBS (816) 563-4845. This is my Home
|
|
of Port and a small but growing hack/phreak node.

FEATURES OF THE TAC ACCESS CONTROL SYSTEM (TACACS)
|
|
|
|
|
|
To log in to the network via a MILNET TAC, you MUST have a unique ID
|
|
and Access Code (TAC Access Card). These cards are issued by the DDN
|
|
Network Information Center (NIC) only after a user has been authorized
|
|
by the Host Administrator of the host on which the user has his
|
|
primary mailbox or account.
|
|
|
|
IF YOU HAVE NOT RECEIVED YOUR TAC ACCESS CARD, AND HAVE A LEGITIMATE
|
|
REQUIREMENT TO ACCESS THE NETWORK VIA A MILNET TAC, CONTACT YOUR HOST
|
|
ADMINISTRATOR! (DO NOT CONTACT THE NIC FOR AUTHORIZATION).
|
|
|
|
If you do not know who your Host Administrator is, you may find out by
|
|
using the "WHOIS" command on the NIC.DDN.MIL host. Instructions on
|
|
using "WHOIS" are as follows: When you finish reading this message,
|
|
type "quit" as instructed. After the connection to NIC.DDN.MIL is closed,
|
|
type "@n" again. You will be told how to find your Host Administrator.
|
|
When finished, type "logout<RETURN>" at the prompt and you will be
|
|
returned to the TAC.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
TACACS, the access control system for MILNET TACs, requires you to log
|
|
in before a connection to a host may be completed. The login process
|
|
is automatically started with the first @open (@o) command you issue.
|
|
There is a @close (@c) command to close the TAC connection and also a
|
|
@logout (@l) command to logout. Otherwise, the functioning of the TAC
|
|
is essentially unaffected by the access control system.
|
|
|
|
Here is a sample of the login dialogue:
|
|
|
|
|
|
First, the command to get the TAC's attention is Control-Q.
|
|
|
|
(a) PVC-TAC 111 #: 01 This is the last line of the TAC
|
|
herald, which the TAC uses to
|
|
identify itself. When you see the
|
|
herald, the TAC is ready for your
|
|
command.
|
|
|
|
(b) @o 26.2.0.8<RETURN> The user inputs the command to
|
|
------------------- open a connection plus the
|
|
internet address of the host to
|
|
which he wishes to connect,
|
|
followed by a Carriage Return.
|
|
|
|
(c) TAC Userid: SAMPLE.LOGIN<RETURN> Here the TAC prompts the user for
|
|
-------------------- his Userid. The user enters his
|
|
ID exactly as shown as shown on
|
|
his TAC Access Card, followed by
|
|
a Carriage Return.
|
|
|
|
(d) Access Code: 22bgx4467<RETURN> Again the TAC prompts the user,
|
|
----------------- who responds by entering his
|
|
Access Code as shown on his TAC
|
|
Access Card, followed by a
|
|
Carriage Return.
|
|
|
|
(e) Login OK The TAC validates the ID/Access
|
|
TCP trying...Open code and proceeds to open the
|
|
requested connection.
|
|
|
|
HELPFUL INFORMATION:
|
|
|
|
When entering your TAC Userid and Access Code:
|
|
|
|
- A carriage return terminates each input line and causes the next
|
|
prompt to appear.
|
|
|
|
- As you type in your TAC Userid and Access Code, it does not matter
|
|
whether you enter an alphabetic character in upper or lower case.
|
|
All lower case alphabetic characters echo as upper case for the
|
|
Userid.
|
|
|
|
- The Access Code is not echoed in full-duplex mode. An effort is
|
|
made to obscure the Access Code printed on hardcopy terminals in
|
|
half-duplex mode.
|
|
|
|
- You may edit what you type in by using the backspace (Control-H)
|
|
key to delete a single character.
|
|
|
|
- You may delete the entire line and restart by typing Control-U.
|
|
A new prompt will appear.
|
|
|
|
- While entering either the TAC Userid or Access Code, you may type
|
|
Control-C to abort the login process and return to the TAC command
|
|
mode. You must interrupt or complete the login process in order to
|
|
issue any TAC command.
|
|
|
|
- The @reset (@r) command resets the TAC and returns you to the TAC
|
|
welcome banner.
|
|
|
|
IF YOU HAVE A PROBLEM WITH TAC LOGIN:
|
|
|
|
Should the login sequence fail (as indicated by the response "Bad
|
|
login"), examine your Access Card carefully to ensure that you are
|
|
entering the ID and Access Code correctly. Note that Access Codes
|
|
never contain a zero, a one, a "Q" or a "Z", as each of these
|
|
characters may be mistaken for another character. If you see what
|
|
appears to be one of these characters in your access code, it is
|
|
really the letter "O" (oh), or "G" (gee), the letter "L" (el), or the
|
|
number "2" (two).
|
|
|
|
If you have followed all of the above steps as indicated, and if you
|
|
are sure you are entering your ID and Access Code correctly, and you
|
|
still cannot log in, call the Network Information Center at (415)
|
|
859-3695 or (800) 235-3155 for help.
|
|
|
|
AFTER LOGGING IN:
|
|
|
|
Your TAC port will remain logged in as long as you have an open
|
|
connection. If you close the connection, you will have ten minutes in
|
|
which to reopen a connection without having to log in again. If you do
|
|
not reopen a connection within ten minutes, the TAC will attempt to
|
|
hang up your port, and will automatically log you out.
|
|
|
|
WHEN YOU ARE FINISHED:
|
|
|
|
Always close the connection using "@c" then log out using the "@l" command.
|
|
Typing "@r" (reset) has no effect on your logged-in status.
|
|
|
|
If you now wish to log in to the TAC, leave the TACNEWS program by
|
|
typing "quit" at the next prompt. This will return you to the TAC,
|
|
and you may then begin the login sequence with the @o command to the
|
|
TAC.
