Greetings wise ones. I have been trying to work with Net::SSH::Perl instead of Expect.pm and ssh, and up until now everything has seemed easy. I am trying to automate "apt-get installing" packages on multiple machines.
I thought: 
($stdout,$stderr,$exit) = $ssh -> cmd ("apt-get install anjuta");

was pretty straightforward, but the ssh connection disconnects right before the package can be installed. I'm not sure what the workaround is. Can anyone offer suggestions? print "the output is: $stdout" looks like this: 
the output is:Reading Package Lists...
Building Dependency Tree...
The following NEW packages will be installed:
  anjuta 
0 packages upgraded, 1 newly installed, 0 to remove and 0  not upgrade
+d.
Need to get 0B/2633kB of archives. After unpacking 6955kB will be used

I think I am close but not quite there. For the curious, here is the whole script: 
#!/usr/local/perl/bin/perl -w
use Term::ReadKey;
use Net::SSH::Perl;
use Net::SFTP;

my @machinelist = qw (
        machine1.myip.com
        machine2.myip.com
);

foreach my $machine (@machinelist) {
  print "We are going to clobber $machine\n";
}

print "is this ok y/n? ";
my $input = <stdin>;
chomp $input;
if (!($input eq "y")) { die; }

print "what is your root password: ";
ReadMode ('noecho');
my $rootpw=<stdin>;
chomp $rootpw;
ReadMode ('normal');
print "\n";

print "are you sure you want to continue y/n? ";
$input = <stdin>;
chomp $input;
if (!($input eq "y")) { die; }

foreach my $machine (@machinelist) {
  my $status=0;
  eval {
    my $ssh = Net::SSH::Perl->new($machine,protocol=>2);
    $ssh -> login ("root", $rootpw);
    my ($stdout,$stderr,$exit) = $ssh -> cmd ("apt-get install anjuta"
+);

    #for debugging
    print "the output is:$stdout\n";

    $status=1;
  }; if ($@) {
    $status=0;
  }
  if ($status) {
    print "$machine updated successfully.\n";
  } else {
    print "there was a failure updating $machine\n";
  }
}

Thanks in advance for any guidance!

UPDATE (for anyone interested). My problem was not a missing -y or anything, but a bad PATH. When I viewed the contents of $stderr, it became pretty apparent that my PATH was set incorrectly. So I changed my command to "export PATH=\"/sbin:/usr/sbin:/usr/bin:...\";apt-get ..." and voila! it works!
cheers!
