4.1.6 Editing Login Script

For some remote gateways, text login is required before PPP negotiation is started. The Prestige 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 Prestige returns the set’s ‘Send’ string to the server.

For instance, a typical login sequence starts with the server printing a banner, a login prompt for you to enter the user name and a password prompt to enter the password:

Welcome to Acme, Inc.

Login: myLogin

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.
