- 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.
