11.4.3 Using Variable Callback
When you use the Variable Callback authentication method, the ASG Guard/ASG Guard Plus will
call you back at whatever number you enter. This authentication method is not as secure as
Fixed Callback. To dial in to the ASG Guard/ASG Guard Plus using the Password/Callback
Variable Callback authentication method:
1.
From your terminal, or terminal emulator, type the proper modem commands followed by the
ASG Guard/ASG Guard Plus telephone number, and then press the ENTER key.
The ASG Guard/ASG Guard Plus responds by requesting that you enter your User ID. From
your User ID, the ASG Guard/ASG Guard Plus will determine that you are using the Variable
Callback method of access.
2.
At the ASG Guard/ASG Guard Plus system prompt, type your User ID and then press the
ENTER key. The ASG Guard/ASG Guard Plus then requests that you enter your password.
Type your password at the system prompt and then press the ENTER key.
NOTE:
As you type your password, the ASG Guard/ASG Guard Plus displays asterisks (*)
for security purposes.
3.
The ASG Guard/ASG Guard Plus will then ask for the number at which to call you back. At
the system prompt, type the number the ASG Guard/ASG Guard Plus is to use to call you
back, and then press the ENTER key. The ASG Guard/ASG Guard Plus then disconnects.
The ASG Guard/ASG Guard Plus will now call you back at the number you gave it. Make
certain that your modem is in auto-answer mode or that you are prepared to answer the call
using modem commands.
4.
After handshaking has been completed, the ASG Guard/ASG Guard Plus will again request
your password. Enter your password at the system prompt. If your password is correct, you
will either be connected to the ASG Guard/ASG Guard Plus or to the host, depending on your
Access Class:
•
If you are connected to the ASG Guard/ASG Guard Plus (Sysop session), you can
perform all of the operations to which your Access Class entitles you.
•
If you are connected to the host port (Host Session), you will have to perform all of the
normal host login procedures.
If you entered your password incorrectly, the ASG Guard/ASG Guard Plus will give you a
second chance to enter the correct password. Retype your password and then press the
ENTER key.
You are permitted three attempts at entering your User ID and three attempts at entering your
password. If the third response is incorrect, the connection is dropped. If you know you
should have access, and that you entered your password correctly, contact your System
Administrator for assistance.
