 Hi All,

I've not been able to start a background process using Net::SSH::W32Perl.

For example:

- - - -
use Net::SSH::W32Perl;

my $ssh = Net::SSH::W32Perl->new('host');
$ssh->login('user', 'passwd');
my $t1 = time;
$ssh->cmd('sh -c "sleep 10"&');
print "elapsed time: ".(time - $t1)."n";

- - - - -

elasped time: 10

- - - - -

I would expect it to be zero. Does anyone know of a workaround for this?

Thanks,
Yishay

 To anyone interested, I've found the answer. You need to close STDIN,
STDOUT, STDERR before starting the process. So the following works:

use Net::SSH::W32Perl;

my $ssh = Net::SSH::W32Perl->new('host');
$ssh->login('user', 'passwd');
my $t1 = time;
$ssh->cmd(' <&; >&; 2>&; sh -c "sleep 10"&;'); # difference is here
print "elapsed time: ".(time - $t1)."n";

-----

elapsed time: 0
