Dear SCO Customer,

a later release of BIND (Berkeley Internet Name Domain) that patches several 
known security holes.


Software Notes and Recommendations
----------------------------------

SLS UOD492A is intended for use on these products:

  SCO Open Server Enterprise System Release 3.0
  SCO Open Server Network System Release 3.0

I. INSTALLING SLS UOD492A

  1. Log in as root.

  2. Prepare the media for installation.

     Download the UOD492A media image file (uod492a.Z), place the file 
     in the /tmp directory, uncompress and dd the file to a floppy by 
     typing the following commands:

       uncompress /tmp/uod492a.Z
       dd if=/tmp/uod492a of=/dev/rfd0

  3. Run custom with the command:

       # custom

     In custom(ADM), choose "Install", then "A New Product", "Entire
     Product", and press <Enter> to continue the installation.

  4. You will then be prompted to install the "UOD492A: BIND 4.9.7 Floppy
     Volume 1" disk.  Since it is already in the floppy drive, just press
     <Enter> to continue.

  5. When you are prompted that the installation was successful, quit out
     of custom(ADM).  The installation of SLS UOD492A is now complete.


II. REMOVING SLS UOD492A

  1. Log in as root.

  2. Execute the command:

       # custom

  3. In custom, choose "Remove", select "UOD492A: BIND 4.9.7", choose "ALL", 
     and then "Yes" when asked if you wish to continue.

  4. Once the removal finishes, quit custom(ADM).  Removal of SLS UOD492A
     is now complete.


If you have questions regarding this SLS, or the product on which it is
installed, please contact your software supplier.

We appreciate your business.
