31.3.5 Editing Login Script
For some remote gateways, text login is required before PPP negotiation is started. The
ZyWALL 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 ZyWALL 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 ZyWALL
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.

Metric
Enter a number from 1 to 15 to set this route’s priority among the ZyWALL’s routes. The
smaller the number, the higher priority the route has.
Private
This parameter determines if the ZyWALL will include the route to this remote node in
its RIP broadcasts. If set to
Yes
, this route is kept private and not included in RIP
broadcasts. If
No
, the route to this remote node will be propagated to other hosts
through RIP broadcasts.

). Press the [SPACE BAR] to enable IP Multicasting or
