AppleTalk Remote Access Product Details
Copyright 1991, Apple Computer, Inc.
AppleTalk Remote Access provides an asynchronous AppleTalk connection through a
modem to another Macintosh and its AppleTalk network. The remote user can
access all the AppleTalk services such as mail, calendars, file servers, and
printers. This software can act as client or server. The software is meant
for personal use, and it is easy to set up and configure. It supports one
connection at a time.
For optimum performance, Apple recommends using a V.32 capable 9600 bps or
faster modem. A 2400 bps modem provides satisfactory access to on-line mail
services or calendaring systems. Connection speeds slower than 2400 bps are
likely to cause AppleTalk to time-out between packets. The software supports
connection speeds of 2400, 9600 and 19200 bps. It requires System 7 or later,
but runs on any CPU capable of running System 7. AppleTalk Remote Access
supports built-in serial ports, not serial cards.
AppleTalk Remote Access behaves as a node on its local network as well as the
remote network, and has access to all services on both networks. As a client
on the remote network, it doesn't allow the rest of the remote network to gain
access to its local network. In other words, it doesn't create two-way access
between networks.
Components
- Remote Access Application -This is the main application that performs these
functions:
• Sets up the connection documents
• Views the status and activity log
• Initiates or terminates a remote connection
• Enables call answering (Calls are answered whether or not the
application is open.)
- Remote Access Setup - This is a control panel device (cdev) that is normally
the first component used after installation. It is used to do the following:
• Select the modem type and modem port.
• Allow incoming calls.
• Set the duration of a connection.
• Enable access to the attached network.
• Control the modem speaker.
- Users & Groups File
AppleTalk Remote Access uses System 7 file sharing to control access.
It uses the same user name and password entered in the file sharing Users
& Groups file. You enter the call back phone number here. If installed
on an AppleShare 3.0 file server, the file server's Users & groups file
controls access.
- Connection Document
A blank connection document appears when you double-click the Remote
Access application. AppleTalk Remote Access uses the document when
initiating a connection. The connection document specifies the caller's
name, password, and phone number of the server Macintosh.
You can save all the configuration information to use later. You can
choose whether to save the password with the connection document.
You can also set the time interval between reminders that the connection
is still active. This is helpful if you're concerned about phone
charges. The default is no reminder.
- Status Window
This window shows the current status of AppleTalk Remote Access with the
following messages:
• "Idle..." when no connections are present or being attempted
• "Waiting to answer incoming call...." when ready to accept calls
• "Waiting for call back..." or "Dialing..." to show the stage of
making connection or answering a call
- Activity Log
This maintains a log of incoming and outgoing calls and connections.
The data wraps after 1000 entries. For auditing and tracking, you can
cut and paste the data into spreadsheets or databases.
- Network adev (Remote Only)
The Remote Only adev is installed in the Extensions folder and appears in
the Network cdev. You can disconnect from the local network and see only
the remote network. Here are two situations where you might need to do
this:
• In the event of a network number conflict:
When a resource on the remote network has the same number as a resource
on the local network, you can access the remote resource using the
Remote Only adev.
• Only a printer port, and no other network connections:
When you must use the printer port for something other than AppleTalk,
you can use the Remote Only adev to free up the printer port. For
example, a non-networked Macintosh with a serial printer connected to
the printer port and a modem connected to the modem port.
- Other Additions to tht Extensions Folder
The installation process places the modem Connection Control Language
(CCL) scripts in the Extensions folder. The scripts appear in the pop-up
menu in the Remote Access Setup cdev.
Installation also places the AppleTalk Remote Access and MNPLink Tool
extensions in the Extensions folder. These extensions create and
maintain a reliable connection.
- Security
AppleTalk Remote Access implements security in several ways:
• Macintosh Level Security
You can implement security from the Macintosh in these three ways:
• Assign each user a password in the User record in the Users & Groups
file. When receiving a call, the password goes through a DES
encryption and authentication procedure similar to AppleShare.
• Set AppleTalk Remote Access to call the user back at a predetermined
number. If an unauthorized caller discovers a password, the call-
back number will connect only the authorized phone number.
• Disable access to the network so the caller can't see beyond the
server Macintosh. Turn off file sharing to deny access to the
server Macintosh as well.
• Network Level Security
The network administrator can set up a Security Zone using a HyperCard
stack. The Remote Access Setup cdev detects this Security Zone, and
requires a password to answer incoming calls. Unauthorized AppleTalk
Remote Access servers can grant access to a network only after
clearance from the network administrator.
The AppleTalk Remote Access application must be open to see the connection
document, status window, and activity log. The other components are
independent of the application.
