Hello monks of Perl Knowledge

I am having an odd problem with SSH connection using Expect module.

As part of an application, I need to execute a command on the remote host via ssh. As it requires a pseduo-tty, I addedd '-t -t' flag to ssh to force it to allocate a pseduo-tty. Without this flag I am getting warning message "Pseduo-terminal will not be allocated because stdin is not a terminal"

The warning/error in question is "tcgetattr: No such device or address". I get this error while passing the password to remote host.

Code snippet below,

use Expect;
my $ssh = new Expect();
$ssh->spawn( "ssh user\@172.23.1.1" );
$ssh->expect(10, "password:");
print $ssh "$passwd\r";
$ssh->expect(65, "\$" );
print $ssh "$cmd\r";
$ssh->expect(65, "\$" );
my $output = $ssh->exp_before();
$ssh->soft_close() ;
print "$output";

Can anyone help me out !

Thanks
