I am trying to get the version information off of a cisco sg300 smart switch. I have decided to use the module Net::SSH2::Cisco which I have used in the past for a cisco phone server. When running the following script 

#!/usr/bin/perl

use warnings;
use strict;
use Net::SSH2::Cisco;

my $host = "<my_host>";
my $user = "<my_user>";
my $password = "<my_password>";

my $session = Net::SSH2::Cisco->new(host => $host);
$session->login(username => $user, password => $password);

my @version = $session->cmd("show version");

print @version;
$session->close;

I get the following error

Net::SSH2 error -18:LIBSSH2_ERROR_PUBLICKEY_UNRECOGNIZED Authentication failed (username/password) authentication failed for user - `cisco' at ./switch.pl line 12

Not really sure what the issue here is. I can ssh into the switch no problem from the command line.

Thanks in advanced

** Update **

I think I have isolated the issue but now need to figure out how to implement it. The issue seems to be related to the expected prompt for the username/login. The switch expects "User Name:" as the prompt. I've switched to using the module Net::Appliance::Session which appears to have a way to allow custom prompts, just a matter of figuring it out now. Help always appreciated.
