Your problem is that you are not making the SSH connection in the first place. Where you have: 
$ssh = Net::OpenSSH->new(host=>$host, user=>$user, password=>$pw) or d
+ie "can't :(\n" . $ssh->error;

[download]
that is not actually testing for failure as new() always succeeds - from the Net::OpenSSH docs: 
This method always succeeds in returning a new object. Error checking 
+has to be performed explicitly afterwards:

my $ssh = Net::OpenSSH->new($host, %opts);
$ssh->error and die "Can't ssh to $host: " . $ssh->error;

I suspect one of your parameters is incorrect. When I log in via SSH I use: ssh username@username.example.com. That translates to: 
my $host = "username.example.com";
my $user = "username";
my $pw = "password";

Also, if you use public key authentication (which you really should) then you need to provide the path to your key.
