Hi. I have created a perl script to connect to Linux box using SSH protocol with Net::SSH:W32Perl module. When I run the script it gets hang at "channel 1: open confirm rwindow 0 rmax 32768" error. I also checked nodes related to this error on perl monks but the solutions didn't help. I have given my script below. Can you please help me to find why the script hangs.

use Net::SSH::W32Perl;

my $host = 'XXXX.com';
my $user = 'AAAAA';
my $pass = 'BBBBB';
my $cmd  = 'ls -l';

my $ssh = Net::SSH::W32Perl->new(
          $host, 
          debug => 1,
          protocol => 2
);
$ssh->login($user, $pass);

my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
print $stdout, "\n";
