I have a simple perl script for SSH to a Linux box. However, each time when I run it, I get the following debug message, followed by a Permission Denied. With the same login ID & password, I can use SecureCRT to SSH into that Linux box. I have search the web to find some hint of how to resolve this problem, but didn't have any luck. Would you please help me? Thank you very much!

------ perl code ------------
use Net::SSH::Perl;
use Net::SSH::Perl;
my %param = ( protocol => '2,1',
              ciphers => 'RC4',
              port => 22,
              debug => 1,
            );
              
my $ssh = Net::SSH::Perl->new("esp-ueh05",%param);
my $rc = $ssh->login("esp", "test");
