So the else if will only run if the first if is not true, that doesn't seem right,.

	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();

	Mike, 

If that does not seem right what can I change it to make it right? 

	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->send("passwd amagana\n");

	$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");

	        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.
