[Ssh-sftp-perl-users] Help using Net::SSH::Perl with automatic authentication

[Eduardo R. A. <er...@gm...>]

Hi everyone!
I hope this list is still active as I just can't find any help on this.
(And this is my first time ever on mailing list!)
I'm trying to ssh to a remote machine inside a Perl script with
automatic/non-interactive authentication. All machines have keys copied so
that when I ssh through an xterm I don't get prompted for a password and I
get logged in to the other machine without issues. Now, I want the same
using Net::SSH::Perl. My code is as follows:

my $ssh = Net::SSH::Perl->new( $host,
                                                'protocol' => 2,
                                                'debug' => 3,
                                                'interactive' => 0,
                                                'identity_files' =>
["$ENV{'HOME'}/.ssh2/id_rsa_2048_a"],
                                               'options' => [

 "AllowedAuthentications publickey",

"QuietMode yes",

"StrictHostKeyChecking no",
                                                ]
);
$ssh->login();

I'm getting at the end of the output (I'm removing Perl's paths for a
shorter output)

Trying pubkey authentication with key file '(home)/.ssh2/id_rsa_2048_a'
Invalid key file type 'SSH2': Can't locate Data/Buffer.pm in @INC (...) at
(...)/Crypt/DSA/Key/SSH2.pm line 71.
BEGIN failed--compilation aborted at (...)/Crypt/DSA/Key/SSH2.pm line 71.
Compilation failed in require at (eval 73) line 1.
BEGIN failed--compilation aborted at (eval 73) line 1.
 at (...)/Net/SSH/Perl/Key/DSA.pm line 64

Under ~/.ssh2 I got  id_rsa_2048_a and  id_rsa_2048_a.pub, When I try the
.pub version I get "Loading private key failed" so I'm guessing
Net::SSH::Perl needs the private key to sign the answer to the challenge
the server sends (I'm not too skilled with ssh authentication so I may be
totally wrong).
I also noticed I don't have configuration files under /etc/ssh/ssh or
~/.ssh but under /etc/ssh/ssh2 and ~/.ssh2 and I noticed on the output it's
trying to read the ssh versions but not the ssh2 versions, maybe the
problem is around there.
Anyway, am I missing something here? Am I using the right key? Can someone
enlighten me please?
Thanks in advance for any help you can provide :)
