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. 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
user name and password in the script, so they will not show in the clear. They are replaced with
the outgoing login name and password in the remote node when the Prestige sees them in a
‘Send’ string. Please note that both variables must been entered exactly as shown. No other
characters may appear before or after, either, i.e., they must be used alone in response to login and
password prompts.
Please note that the ordering of the sets is significant, i.e., starting from set 1, the Prestige will
