[Expectperl-discuss] expect.pm header for updating password

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I think I need a log file to identify where the script failed. But I am not able to get a header as recommended. 

I am  getting this error:

Global symbol "$system" requires explicit package name at ./tester-a line 7.
Execution of ./tester-a aborted due to compilation errors.

I am trying to use the header suggestion by Don but I am just not able to get it to work,  

#!/usr/bin/perl
use strict;

use Expect;

my $timeout = 60;
my $header = "\n\n======= $system =======\n";
my @servers = qw(
    Solaris-host
    Solaris-host
    Solaris-host 
    Solaris-host
);

for my $server (@servers) {
# do your thing with $server

    change_password($server);

 }

sub change_password {
            my $system = shift;

my $filename = "/var/tmp/expect_script.log";
my $ssh = Expect->new('ssh amagana@' . $system);

$ssh->debug(1);
$ssh->expect ( $timeout,
      [ qr/Password:/],
      [ qr/Are you sure you want to continue connecting \(yes\/no\)?/]
      );

if ($ssh->match() =~ m/Are you sure you want to continue connecting \(yes\/no\)?/ ) {
$ssh->send("yes\r");
}

elsif ($ssh->match() =~ m/Password:/ ) {

$ssh->send("mycurrentpassword\n");

}

$ssh->expect(60, '$');
$ssh->print_log_file($header);
$ssh->send("su - root\n");
$ssh->expect(60, 'Password:');
$ssh->send("rootpassword\n");
$ssh->expect(60, '#');
$ssh->send("passwd amagana\n");
$ssh->expect(60, 'New Password:');
$ssh->send("mynewpassword\n");
$ssh->expect(60, 'Re-enter new Password:');
$ssh->send("mynewpassword\n");
$ssh->expect(60, '#');
$ssh->close();
}

You will need to expect multiple things and then check to see what you got and handle that.
It has been a long time since I did this on solaris so I may have the order wrong...

my $timeout = 60;
$ssh->send("passwd amagana\n");
$ssh->expect( $timeout,
	[ qr/New Password/],
	[ qr/ Are you sure you want to continue connecting/]
	);

If ( $ssh->match() =~ m/New Password/ ) {
	$ssh->send("mynewpassword\n");
}
elsif ($ssh->match() =~ m/ Are you sure you want to continue connecting/ ) {
	$ssh->send("yes\n");
	# then here put in what you expect to get next such as "New Password"
	# then send it the response such as "mynewpassword\n"
}
# continue on with the rest of your script $ssh->expect(60, 'Re-enter new Password:');

Now that I have a working script and thanks very much to you Matt and Don, 

I am trying to put in my script an if else because sometimes my script will encounter this :

Are you sure you want to continue connecting (yes/no)?')

what I did create are some variables is this correct and may I see an example if statement so that the script can make a decision and keep going?

use Expect;
my $knownhost = $ssh->expect(60, 'Are you sure you want to continue connecting (yes/no)?'); my $answer = $ssh->send("yes\n"); my $filename = "/var/tmp/expect_script.log";

I think you will want a log file to identify where the script failed.

I recommend that you take out the 'w' from the $ssh->log_file($filename, 'w'); so it will append to the file rather than over writing it for each server. 

And then put in some sort of header for each server, something like:
my $header = "\n\n======= $system =======\n"; $ssh->print_log_file($header);

Or if you prefer a separate file for each server, then my $filename = "/var/tmp/expect_script_". $system ".log";

little stuff like this can be very frustrating.

Maybe spend a day or two writing some basic perl programs so you feel more comfortable with this stuff. I'm sure there are truckloads of perl tutorials out there.

I added some context below. You'll need to clean up the leading '>' characters.
