Hi everyone, I've got a problem with key authentication using Net::OpenSSH. The problem is I have read the documentation and simply I couldn't find anything about it there. I tried to do it in normal way, as with ssh so I created a pair of keys, copied public to the remote server, tried login from CLI, worked. When did it from script it says "unable to establish master SSH connection: ssh master exited unexpectedly". 
$ENV{HOME} = "/var/www/scripts/new";
use Net::OpenSSH;
use Date::Simple ('date', 'today');
use warnings;
my $ssh;

$ssh = Net::OpenSSH->new('root@localhost', master_opts => [-o => "User
+KnownHostsFile=/dev/null", -o => "StrictHostKeyChecking=no"], timeout
+ => 10, ctl_dir => $ENV{HOME}) or
$ssh->error and die "Couldn't establish SSH connection: ". $ssh->error
+;
my $cmd = "ls -l";
my (@out, $err) = $ssh->capture({ timeout => 10 }, $cmd);
$ssh->error;
print $ssh->error;
foreach (@out)
{
print $out[$i]. "<BR>";
$i++;
}

Obviously when I put the password in it works. It also works from the command line. Directory /var/www/scripts/new contains .ssh/ directory with id_rsa and id_rsa.pub now even with 777 to avoid a mistake in user rights. I'm running that script from other .cgi by system function. And also here when I put password everything works. Thank you for your all answers. Regards, Jarek
