NOTICE: There are no restrictions for distribution of this
Bulletin provided that it remains complete and intact.

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

 -----------------------------------------------------------------
PROBLEM: Some security scanners generate warnings that the
         Jetdirect ftp directory is writable.

IMPACT: Any file sent to the Jetdirect ftp is printed.

PLATFORM: Any Jetdirect device.

SOLUTION: The ftp service can be disabled if desired.

MANUAL ACTIONS: Non-HP-UX only

 -----------------------------------------------------------------
 A. Background

    Any file sent to the Jetdirect ftp service is printed.
    Because certain ftp directories have write permissions
    some security scanners report errors.



 B. Recommended solution

    If you wish to restrict printing or suppress the security
    scanners warning, the ftp service can be disabled.

    To disable ftp, telnet to the Jetdirect device and type:

       ftp-config: 0

    When this change is made printing via ftp will no longer
    function.  It will also not be possible to update firmware
    via ftp.  The firmware can be updated using the
    HP Download Manager or Web Jetadmin.
