Folks,

I am trying to use Net::SSH::Perl to do a non-interactive login to a system and run quite a few commands. The output of those commands would go to individual files. I cant seem to get it to log in noninteractivly. It fails on the ssh->login line below. I dont want to use a password or a passphrase. Any ideas what I am doing wrong? I am quite stumped.. I have ssh (openssh 3.5p1) currently setup so that from the normal command line, I can just type "ssh hostname" and access the system without typing a password or passphrase (I am well aware of the security implications). Its using rsa public keys I believe since I have a id_rsa and id_rsa.pub files in my home directory on the host I am running this from. I am running this as my normal userid not root.

Thanks,
Crayola

        $row = $csv_array[$i];
            my($out, $err) = $ssh->cmd("$row->[0]");         

        # eventually we will pump all the output to a database
        # but for now.. it goes to individual files
        open (OUTFILE,">$host-$row->[1]");

        $out = "";
