unable to connect to SuSE using net::ssh::perl module

Hi,


I am trying to connect from Fedora Core 4 machine to SuSE 9 Enterprise
Server machine using Net::SSH::Perl module. My code terminates at the
call of the login method with a "Permission denied" message. The
credentials provided by me are correct I am able to SSH to the SuSE
machine from the terminal using the same credentials as in the perl
program. Can someone please help me figure out the problem.


the OpenSSH version on the SuSE machine is OpenSSH_3.8p1 and
the OpenSSH version on the Fedora machine is OpenSSH_4.2p1.

the perl installed is perl-5.8.6-15

the Net::SSH::Perl i am using is Net-SSH-Perl-1.29


my code :


sub ssh_connect{


my($host,$uname,$pwd,$cmdstr)=@_;

#opening connection with the remote host by creating object and
providing credentials

my $objfnssh = Net::SSH::Perl->new($host,compression=>1, debug=>1,
protocol=>'2,1');
$objfnssh->login($uname,$pwd);

my @out=$objfnssh->cmd($cmdstr);
#print @out;


}



output :
