I can't make backup

[Javier Ferruz]

        I run tapetype xxxxxx /dev/st0 and create an input to amanda.conf

        When I execute amcheck I get 2 errors:

        - server side : /dev/st0 no amanda tape. I probed /dev/nst0 too
        - client side : <hostname> : [acces as <user> not allowed from 
        <user@hostname>

        I've create .amandahosts en home directory backup user.

        My host is Dell with Debian Linux and scsi tape

        Thanks for advance
