Before connecting to a remote network (see Section 6.1, Using Connection Documents to Connect to Remote Networks ) , you must properly configure your network connections and create a connection document.
 A connection document is an InterPPP file you create and configure
for the particular modem and remote network you are planning on
connecting to. InterPPP uses this file to record your preferences and
information such as your IP address and modem type.
InterPPP provides default scripts for generic modem types. If you need to create or modify a CCL script, see Appendix B, CCL Scripts , for more information.
  A CCL script is a file, stored in the Extensions folder, that is written
in the Connection Control Language and contains information,
such as commands, necessary to connect your modem to the remote
network.
InterPPP uses connection documents to record the information it needs to connect to the desired remote network. After a connection document is created, configured, and saved, you can double-click the connection document icon to automatically launch InterPPP. InterPPP is then ready to connect using its previously configured parameters.
Before you configure your connection document your network connections must be properly configured. See Chapter 3, Configuring Your Network Connections , for more information.
4.1 Creating a New
Connection Document
Before connecting to a remote network through InterPPP, you must first create a connection document that configures the PPP system driver for your modem.
To create a connection document:
1. Launch InterPPP by double-clicking the InterPPP icon.
OR
Select New Connection… from the File menu if InterPPP is already
running.
‚àö An untitled connection document is displayed (Figure 4.1).
 
Figure 4.1 An Untitled Connection Document
2. Specify the authentication parameters for InterPPP by clicking either
No Authentication or Authenticated User.
• Click No Authentication for InterPPP to allow any user to connect and
proceed to Step 6.
OR
• Click Authenticated User for InterPPP to require authentication (using
either PAP or CHAP) before allowing a user to connect. Select this
only if your server supports this feature.
  The type of authentication InterPPP uses, either PAP or CHAP, is
determined in the PPP Configuration dialog. See Section 5.2, PPP
Configuration , for more information.
  PAP (Password Authentication Protocol) is a protocol that enables
your Macintosh to identify itself to a remote network. After an
initial link is established, your Macintosh sends the remote network
an ID/Password pair in plain text. If the remote network accepts
the pair, the connection is made. If it does not accept it, the
connection is dropped.
 CHAP (Challenge-Handshake Authentication Protocol) is a
protocol that enables your Macintosh to identify itself to a remote
network. After an initial link is established, the remote network
sends a challenge that prompts your Macintosh to calculate a
response. If this response matches the response that the remote
network calculates, the connection is made. If they do not match,
the connection is dropped. CHAP is considered more secure than
PAP since no confidential information is passed in plain text.
‚àö If Authenticated User is selected, the Connection Document window
changes to include a Name and Password field and a Save my
password checkbox (Figure 4.2).
 
Figure 4.2 A Connection Document with Authenitcation Selected
3. In the Name field, enter your user name for the server you are
connecting to.
4. In the Password field, enter your user password for the server you are
connecting to. Your password is masked by dots (••••).
5. Check Save my password for your password to be saved as part of
this connection document.
6. In the Phone field, enter the number that the modem is to dial to
connect to the remote network.
7. Check the Remind me checkbox to be notified of an idle connection.
Enter the amount of time in the minutes field that InterPPP should
wait before displaying a reminder.
8. Select Save from the File menu to save the connection document.
√ Apple’s standard Save dialog (Figure 4.3) is displayed.
 
Figure 4.3 Apple’s Standard Save Dialog
 You can save your connection documents anywhere you like. Saving
your connection documents on your desktop or in your InterPPP
folder would be especially convenient. If you save your connection
document in your Startup Items folder, you can take advantage of
the Dial on Demand feature of InterPPP.
 Dial on Demand is an InterPPP feature that is active as soon as you
turn on your Macintosh. It configures PPP at boot time and starts a
connection when you try to access a network service. To implement
this feature, save a connection document to the Startup Items folder
in your System Folder. Only one connection document can be
located in the Startup Items folder at a time.
9. Name the connection document, select the location where it is to be
saved, and click Save. (Or click Cancel to close the dialog without
saving the document.)
‚àö The name of the connection document is displayed at the top of the
window (Figure 4.4).
 
Figure 4.4 A Configured Connection Document
10. Configure the modem settings for this connection document by
following the procedures in Section 5.1, Modem Configuration.
11. Configure the PPP settings for this connection document by
following the procedures in Section 5.2, PPP Configuration.
12. Configure the TCP/IP settings for this connection document by
following the procedures in Section 5.3, TCP/IP Configuration.
  Many of the configuration dialogs do not have Cancel buttons to
undo undesired changes. If you make changes to the settings of a
connection document that you want to undo, close the document
without saving the changes. When the document is re-opened, the
settings are unchanged.
4.2 Closing a Connection Document
without Saving Any Changes
To close a connection document without saving any changes:
1. Click the close box in the upper left hand corner of the Connection
Document window.
√ Apple’s standard Close dialog (Figure 4.5) is displayed.
 
Figure 4.5 Apple’s Standard Close Dialog
2. Click No in the Close dialog to indicate that no changes are to be
saved.
‚àö The connection document is closed and no changes are saved.
4.3 Opening and Editing
a Connection Document
To open and edit an existing connection document:
1. Select Open Connection… from the File menu.
√ Apple’s standard Open File dialog (Figure 4.6) is displayed.
 
Figure 4.6 Apple’s Standard Open File Dialog
2. Select a connection document and click Open. (Or click Cancel to close
the dialog without opening a connection document.)
‚àö The selected document opens (Figure 4.7).

3. Follow the procedures in Section 4.1, Creating a New Connection
Document, to edit specific parameters for the connection document.
4. Select Save from the File menu to save the changes you have made to
this connection document. (Or click the close box to close the document
