Strange messages when using Net::SSH::W32Perl

[prabu]

while running this script on windows xp

use Net::SSH::W32Perl;
my $host = "debian30";
my $user = "user";
my $pass = "password";
my $cmd = "perl debian30_remote_script.pl";
my $ssh = Net::SSH::W32Perl->new($host, port=>22, debug => 0,
interactive => 1);
$ssh->login($user, $pass);
$ssh->cmd('cd', "/home/test");
my($stdout, $stderr, $exit) = $ssh->cmd($cmd);


Here the remote script was ran successfully.But i don't know why these
strange messages(below) appeared.How can I get rid of these messages?
