I wanted to achieve the following result: 1) I can loop on list. - solved 2) I can loop to list of user. - solved 3) Reset/update each users password on each server - not solve yet I had this script. 
#!/usr/bin/perl

use strict;
use warnings;
use Net::SSH::Perl;
use Expect;

my $logs = "logs";
open(LOG,'>>',"$logs") or die "can't logs $!\n";

my $domain = 'domain.com';
my @host = qw/host/;

foreach my $host (@host) {
   my $cmd = "passwd user1";
   my $sshost = join('.', $host, $domain);
   my $ssh = Net::SSH::Perl->new("$sshost");
   $ssh->login('root');
   $ssh->debug();
   my ($stdout, $stderr, $exit) = $ssh->cmd($cmd);
   print LOG $stdout,"\n";
}

Basically my problem now are: 1) I'm not allowed to install another module(politics/not rights). 2) I don't have idea how to send/supply password after the execution of $cmd and the prompt will come out.

In reply to How do I send a password to a command I start with Perl's Expect.pm by jt_exist
