I am trying to write a script that will simulate a superuser log in attempt failure, but I'm not sure how to send a password to the terminal when the terminal requests a password.

    this should get you started:
    use strict; use warnings; use Expect; my $timeout = 5; my $password = "password"; my $shell_prompt = ']$ '; my $exp = new Expect; $exp->raw_pty(1); $exp= Expect->spawn("su") or die "Error calling su: $!\n"; unless ($exp->expect(5,"Password: ")) { die; # add error handling }; $exp->send("$password\n"); unless ($exp->expect(5, $shell_prompt)) { die; # add error handling }; print "Login successful\n";

Log In?
Username:
Password:

What's my password?
