As an alternative, that could be replaced with:
my $chan = $ssh2->channel();
my ($len, $buf) = (1000, ' ' x 1000);
$chan->exec("ls\n");
$chan->read($buf, $len);
print $buf, "\n";
One problem with that replacement code is that you need to allocate a
sufficiently large buffer ($buf). It doesn't matter if $buf is larger than
necessary, but if it's smaller than needed then you miss out on the "extra"
data.

It's not an error message - it's a warning which you could eliminate with
(at the beginning of your script):
no warnings 'uninitialized';
I get the same warning with your code, but I also get the "ls" output
printed out before the warning appears. Is it the same for you ?
Are you using perl 5.8.x or 5.10.0 ?
Cheers,
Rob
