Hello Mike, Don and Matt,
At the point I am at this list of servers in my script I would really need someone with more experience to see if I even have the right scripting.
#!/usr/bin/perl
use strict;
use Expect;
my $timeout = 60;
my @servers = qw(
remotehost03
remotehost04
remotehost05
remotehost06
);
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:/ ) {
$ssh->send("mypassword\n");
}
#$ssh->log_file($filename, 'w');
$ssh->expect(60, '$');
$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();
Respectfully,
#!/usr/bin/perl
use strict;
use Expect;
my $timeout = 60;
my $filename = "/var/tmp/expect_script.log";
my $ssh = Expect->new('ssh amagana at remotehost');
$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:/ ) {
$ssh->send("mypassword\n");
}
#$ssh->log_file($filename, 'w');
$ssh->expect(60, '$');
$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();

Try something like this:
my $exp = new Expect;
$exp->log_stdout(1);
$username = "XXXXXX";
$exp->spawn( "ssh -l ${username} ${ip} " ) or die "cannot spawn $command: $! \n";
$exp->log_file("./${log_dir}/$ip\_info.log");
print "\nspawning ssh connection to $ip on $time\n\n";
$exp->log_file->print( "\nspawning ssh connection to $ip on $time\n\n" );
$exp->expect(8,
[ 'connecting' => sub { $exp->send("yes \n"); exp_continue; } ],
[ 'assword:' => sub { $exp->send("$pw\n"); exp_continue; } ],
[ '-re', '> ?$' => sub { break; }],
[ 'try again' => sub { die " died from bad password.\n"; }],
[ 'refused' => sub { die " died from connection refused.\n"; exp_continue; } ],
[ eof => sub { die " died from eof.\n"; }],
[ timeout => sub { $exp->hard_close(); }],
);

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.
