Subject: [Backupgem-users] Net::SSH::AuthenticationFailed in rotation via ssh
Message-ID: <5d94b09f1002220838l668737c4x93ca30135adcce53@mail.gmail.com>

I've got this error message when doing a backup via SSH.

My backup file is:

set :backup_path, "backup"
#set :tmp_dir, "/tmp"

set :action_order,      %w{ content compress encrypt deliver rotate cleanup }
set :servers,		%w{ 192.168.0.10 }
set :ssh_user,          ENV['USER']
set :identity_key,      ENV['HOME'] + "/.ssh/id_rsa"
set :port,          22

set :son_promoted_on, :fri
set :father_promoted_on, :last_fri_of_the_month

set :sons_to_keep, 5
set :fathers_to_keep, 3
set :grandfathers_to_keep, 1

action :content, :is_folder => "~/bin"

action :deliver, :method => :scp
action :rotate,  :method => :via_ssh

As you can see, was not possible to authenticate. But, the file
/tmp/bin.tar.bz2 was sucessfull copied, the error occur during
rotation process.
I have tested not doing the rotation, removing rotate from
:action_order and everything works ok.

I've looked at ssh_helper.rb file and the function Net::SSH.start has
wrong syntax in Backup::SshActor.connect, it is:

    def connect
      c[:servers].each do |server| # todo, make this actually work
      @session = Net::SSH.start(
           server,
           :port         => c[:port],
           :username    => c[:ssh_user],
           :host_key     => "ssh-rsa",
           :keys         => [ c[:identity_key] ],
           :auth_methods => %w{ publickey } )
      end
    end

But, looking at syntax of Net::SSH::start
(http://net-ssh.rubyforge.org/ssh/v2/api/index.html)

  start(host, user, options={}) {|connection| ...}

I think it should be something like:

    def connect
      c[:servers].each do |server| # todo, make this actually work
      @session = Net::SSH.start(
           server, c[:ssh_user],
           :port         => c[:port],
           :host_key     => "ssh-rsa",
           :keys         => [ c[:identity_key] ],
           :auth_methods => %w{ publickey } )
      end

I would like to describe another mistake I found on code.

At file ssh_helper.rb in method Backup::Command.open_channels you are
using methods on_success and on_failure but this methods don't exist
in Net::SSH::Connection::Channel definition
(http://net-ssh.rubyforge.org/ssh/v2/api/classes/Net/SSH/Connection/Channel.html)
and method on_request need to get an argument.
