Thank you Don and Matt and Mike,
Your help got me here and I learned so much and there is much more to learn but I enjoy it. My script has a list of four Solaris 10 servers. Launching the perl expect.pm script from a Red Hat server it went to each box and changed my password with no problems. Thank you again. Here is the example script I used.
#!/usr/bin/perl
use strict;
use Expect;
my $timeout = 60;
my @servers = qw(
Solaris-host03
Solaris-host04
Solaris-host05
Solaris-host06
);
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);
#my $ssh = Expect->new('ssh amagana at tstorweb01');
$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");
}
$filename = "/var/tmp/expect_script_". $system ".log";
$ssh->expect(60, '$');
$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();
}

Subject: RE: updating list of server account password
It looks to me like it will work.
There is NO WAY that I would run a password changing script without logging everything I did.
I would suggest again that you log the results. You have that line commented out. And with the 'w' you will overwrite the log everytime you run that sub so it will only have the last server you run it on. I suggest that you take out the 'w'. With the 'w' everytime you call that sub it will wipe out the file. This means that when you one it for remotehost6 it will wipe out everything from remotehost5
So I recommend that you replace:
#$ssh->log_file($filename, 'w');
With
$ssh->log_file($filename);
I also recommend that you put in a couple of exits; 1 to close the root shell and the other to close your login shell.
If you prefer a safer test, try running the hostname command rather than the passwd command.
$ssh->expect(60, '$');
$ssh->send("su - root\n");
$ssh->expect(60, 'Password:');
$ssh->send("rootpassword\n");
$ssh->expect(60, '#');
$ssh->send("hostname\n"); # you might want to leave this in anyway to make reading the log easier $ssh->expect(60, '#'); $ssh->send("uptime\n"); #$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->send("exit\n"); $ssh->expect(60, '$'); $ssh->send("exit\n"); $ssh->close();

Subject: updating list of server account password
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');

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');

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");

Subject: RE: [Expectperl-discuss] expect.pm not updating password
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.
