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.
Please note that the ordering of the sets is significant, i.e., starting from set 1, the ZyWALL
will wait 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
ZyWALL will terminate 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 should match the final message sent by the server. For instance, if the server prints:
login successful.
Starting PPP...
after you enter the password, then you should create a third set to match the final “
PPP...
”
but without a “Send” string. Otherwise, the ZyWALL will start PPP prematurely right after
sending your password to the server.
If there are errors in the script and it gets stuck at a set for longer than the “Dial Timeout” in
menu 2 (default 60 seconds), the ZyWALL will timeout and drop the line. To debug a script,
go to Menu 24.4 to initiate a manual call and watch the trace display to see if the sequence of
messages and prompts from the server differs from what you expect.
