Editing logon script

For some remote gateways, text logon is required before PPP negotiation is

started. The Business Secure Router provides a script facility for this purpose. The

script has six programmable sets; each set is composed of an Expect string and a

‘Send’ string. After matching a message from the server to the ‘Expect’ field, the

Business Secure Router returns the set’s Send string to the server.

For instance, a typical logon sequence starts with the server printing a banner, a

logon prompt for you to enter the username and a password prompt to enter the

password:

Welcome to Acme, Inc.

Password:

To handle the first prompt, you specify ogin: as the Expect string and myLogin as

the Send string in set 1. The reason for leaving out the leading L is to avoid having

to know exactly whether it is upper or lower case. Similarly, you specify word: as

the Expect string and your password as the Send string for the second prompt in

set 2.

You can use two variables, $USERNAME and $PASSWORD (all upper case), to

represent the actual username and password in the script, so they do not show in

clear text. They are replaced with the outgoing login name and password in the

remote node when the Business Secure Router sees them in a ‘Send’ string. Note

that both variables must be entered exactly as shown. No other characters can

appear before or after, either, i.e., they must be used alone in response to logon

and password prompts.

Note that the ordering of the sets is significant, i.e., starting from set 1, the

Business Secure Router waits until the ‘Expect’ string is matched before it

proceeds to set 2, and so on for the rest of the script. When both the ‘Expect’ and

the ‘Send’ fields of the current set are empty, the Business Secure Router

terminates the script processing and start PPP negotiation. This implies two

things: first, the sets must be contiguous; the sets after an empty one are ignored.

Second, the last set must match the final message sent by the server. For instance,

if the server prints:
