OK, here's a strange problem..

My code can connect to localhost just fine, and behaves as expected.

Yet, anything but localhost doesn't work and errors out in the way I'm showing below.

Any ideas? (and yes, the login/password combo is correct, and I can manually connect with ssh using the same login credentials as I'm trying here)

-------------------------- 

#!/usr/bin/perl
use warnings;
use strict;
use Net::SSH2;
use Data::Dumper;

my $hostname = shift;
chomp($hostname);

my $ssh2 = Net::SSH2->new();
$ssh2->connect($hostname) or die "cant connect to $hostname: $@ \n";
$ssh2->auth_password('root','mypassword') or die "cant login to $hostn
+ame: $@ \n";

my $chan = $ssh2->channel();
$chan->blocking(0);
$chan->shell();

print $chan "uname -a\n";
my @uname = <$chan>;
print @uname;

print $chan "who\n";
my @who = <$chan>;
print @who;

$chan->close;
