All, I am trying to get net sftp to work without password authentication. I want it to use a pub keys. By default it uses id_dsa or identity file. I have a pub with different name. I try this:

 $sftp = Net::SFTP->new("myhost" ,  user=>"me", ssh_args => ( identify
+_files => [ "PATH/.ssh/id_rsa" ,"PATH/.ssh/myid_file"],debug => '1', 
+options => {"RhostsAuthenication no"} ) );

Any idea, why it's not using the identify file, but each time it tried using id_dsa instead? Thanks.
