Hello,

I'll try to make this short. I've successfully been able to connect to my SSH server using Net::SSH2. All is dandy, except I had some issues trying to run commands and gather the output. So that had me trying Net::SSH:Any using the SSH2 backend. I cannot connect as I receive an authentication error. I think I have pegged it to an issue with the publickey file.

Net::SSH2 code: 
    $ssh2= Net::SSH2->new();

    my $host = 'serveraddress';
    my $port = 22;
    my $user = 'username';

    $ssh2->connect($host, $port) or $ssh2->die_with_error;

    my $ppk_filepath = 'C:\Users\username\rsa-key-username';

    print "$ppk_filepath exists!\n" if -e $ppk_filepath;

    $ssh2->auth_publickey($user, undef, $ppk_filepath, 'passphrase123'
+ ) or $ssh2->die_with_error;

This code works and I connect and can authenticate. But in fact, if I were to place my LOCAL publickey file path where undef currently is I would get authentication errors. I believe with undef it some how infers a .pub file from my private key. From SSH2.pm source:

"When libssh2 is compiled using OpenSSL as the crypto backend, passing this method C<undef> as the public key argument is acceptable (OpenSSL is able to extract the public key from the private one)."

    use Net::SSH::Any;
    $Net::SSH::Any::debug = -1;

    my $host = 'serveraddress';
    my $port = 22;
    my $user = 'username';    
    my $ppk_filepath = 'C:\Users\username\rsa-key-username';

    $ssh2 = Net::SSH::Any->new($host, port => $port, user => $user, pa
+ssphrase => 'passphrase123', key_path => $ppk_filepath, backends => '
+Net_SSH2');

    if ($ssh2->error) {
        die "Connection error: " . $ssh2->error;
    }

Here I get an authentication error. I understand that it's looking for the .pub file, which I do have in the same directory as my privatekey file. Everything seems correct here. I've searched all over Google and Perl Monks for an answer and I appreciate all the info from Salva (that has helped me get Net::SSH2 up and running) but I cannot find too much about SSH::Any with SSH2 backend. Thanks for any help, from a beginnner.
