If your administrator does not allow you to use keys for security reasons, they will be livid to discover you getting around this limitation with an insecure third-party brute forcing tool.

expect_expectl
EXPECT_EXPECTL(3) 1 EXPECT_EXPECTL(3)
expect_expectl - Waits until the output from a process matches one of the patterns, a specified time period has passed, or anEOFis seen
SYNOPSIS
int expect_expectl (resource $expect, array $cases, [array &$match])
DESCRIPTION
Waits until the output from a process matches one of the patterns, a specified time period has passed, or an EOF is seen.
If $match is provided, then it is filled with the result of search. The matched string can be found in $match[0]. The match substrings
(according to the parentheses) in the original pattern can be found in $match[1], $match[2], and so on, up to $match[9] (the limitation of
libexpect).
PARAMETERS
o $expect
- An Expect stream, previously opened with expect_popen(3).
o $cases
- An array of expect cases. Each expect case is an indexed array, as described in the following table:

| | | | | |
| | EXP_GLOB | | | |
| | | | | |
+----------+--------------------------+---+---+---+
RETURN VALUES

$cases = array(
// array(pattern, value to return if pattern matched)
array("password:", "asked for password"),
array("yes/no)?", "asked for yes/no")
);
while (true) {
switch (expect_expectl($stream, $cases)) {
case "asked for password":
fwrite($stream, "my password
");
break;
case "asked for yes/no":
fwrite($stream, "yes
");
break;
case EXP_TIMEOUT:
case EXP_EOF:
break 2; // break both the switch statement and the while loop
default:
die "Error has occurred!";
}
}
fclose($stream);
