       pt_util - Load or dump a Protection Server database


          [-w] [-user] [-group]
          [-members] [-name] [-system]
          [-xtra] [-prdb <prdb file>]
          [-datafile <data file>] [-help]


       The pt_util command can be used to load or dump the protection database.  It should only
       be used when ptserver is not running.

       The most likely reason to use it is to initialize the protection database when bringing up
       a new cell.  The current syntax for this, presented below, needs improvement.  pt_util can
       also be used when problems are suspected with the database.  It can be used to dump the
       database or portions thereof, in several different ways, and to reload it.

       The textual representation of the database has the following form: For users,

           name flags/quota viceid ownerid creatorid

       For groups,

           name flags/quota viceid ownerid creatorid
            a-username a-user-viceid

       The second line is repeated for each member of the group.  When reading the database,
       membership is not reported unless -members is also included.


       If you don't specify any options, the only thing you'll learn is the ubik database epoch
       and version.

       -w  Write to the protection database instead of reading.  Only the file arguments make
           sense in combination with this argument.

           When reading, display users.

           When reading, display groups (but not necessarily members).

           When reading, display groups and also group members.

           When reading, follow name hashes, instead of id hashes.  This may print different
           information if the database was corrupted.  Otherwise, it should print exactly the
           same information, except in a different order.

           When reading, display system data, or more precisely, do not display entries with a
           viced <= -32768 or >= +97537.

           When reading, display extra users and groups, or more precisely, do not display
           entries that are in the range -32767...+97536 inclusive.

       -prdb <prdb file>
           Specifies the complete pathname of the file in which the Protection Database resides.
           Provide the complete name, including the ending .DB0.

       -datafile <data file>
           Specify the file to which to dump (or -w from which to read) textual database records.


       The file dump format does not include supergroup information, so should not be used if you
       have and are using groups within groups.

       In all cases, entry timestamps and other information is also not preserved.

       The epoch and version are reported on standard error.  On little-endian machines, they'll
       be byte swapped, so may be very random.


       The following example shows how to initialize the database from scratch.

       Before you do this, make sure ptserver is not running.  If you have multiple database
       servers, make sure prdb.* does not exist on any server machine.

       Now, type this in EXACTLY, including the leading space on the line indicated.  But do use
       Control-D at the end, not up-arrow D.

           pt_util -w
           admin 128/20 1 -204 -204
           system:administrators 130/20 -204 -204 -204
            admin 1

       You will see this:

           # pt_util -w
           pt_util: /var/lib/openafs/db/prdb.DB0: Bad UBIK_MAGIC. Is 0 should be 354545
           Ubik Version is: 2.0
           admin 128/20 1 -204 -204
           system:administrators 130/20 -204 -204 -204
           Error while creating system:administrators: Entry for id already exists
            admin 1
           pt_util: Ubik Version number changed during execution.
           Old Version = 2.0, new version = 33554432.0

       To make a complete copy of the database,

           # pt_util -user -members -datafile /tmp/out

       To load from the complete copy,

           # pt_util -w -datafile /tmp/out

       Don't do this until you read cautions, above.
