[Ssh-sftp-perl-users] Cannot connect with Net::SSH::Perl module to localhost

[Bogdan C. <cri...@gm...>]

I have used the following snippet:

my $scon = Net::SSH::Perl->new ("localhost");
$scon->login("bogdan","xxx");
print "looking around ...\n";
my ($output,$errors,$exit) = $scon->cmd("ls -l");
print $output;

and I get the following warnings/error:

Math::BigInt: couldn't load specified math lib(s), fallback to 
Math::BigInt::FastCalc at /usr/lib/perl5/site_perl/5.10.0/Crypt/DH.pm line 6
Permission denied at ./trial_ssh.pl line 8

Using ssh I am able to connect to localhost, but I would like to have the 
ability to provide a password as command line argument for the ssh client. I 
use openSUSE 11.1, x86_64. Could someone suggest how to fix the above code ?
