       ptserver - Initializes the Protection Server

       The ptserver command initializes the Protection Server, which must run
       on every database server machine. In the conventional configuration,
       its binary file is located in the /usr/lib/openafs directory on a file
       server machine.

       The ptserver command is not normally issued at the command shell
       prompt, but rather placed into a database server machine’s
       /etc/openafs/BosConfig file with the bos create command. If it is ever
       issued at the command shell prompt, the issuer must be logged onto a
       file server machine as the local superuser "root".

       The Protection Server performs the following tasks:

       ·   Maintains the Protection Database, which contains entries for every
           user and group in the cell. Use the pts commands to administer the

       ·   Allocates AFS IDs for new user, machine and group entries and maps
           each ID to the corresponding name.

       ·   Generates a current protection subgroup (CPS) at the File Server’s
           request. The CPS lists all groups to which a user or machine

       When using Kerberos 5, cross-realm authentication is possible. If the
       special pts group system:authuser@FOREIGN.REALM exists and its group
       quota is greater than zero, aklog will automatically create an entry
       for the foreign user in the local PTS database and add the foreign user
       to the system:authuser@FOREIGN.REALM PTS group.  Each time a foreign
       user is created in the local PTS database, the group quota for the
       system:authuser@FOREIGN.REALM PTS group is decremented by one.

       This command does not use the syntax conventions of the AFS command
       suites. Provide the command name and all option names in full.


       -d <debug level>
           Sets the detail level for the debugging trace written to the
           /var/log/openafs/PtLog file. Provide one of the following values,
           each of which produces an increasingly detailed trace: 0, 1, 5, 25,
           and 125.

       -database <db path>, -db <db path>
           Specifies the pathname of an alternate directory in which the
           Protection Database files reside. Provide the complete pathname,
           ending in the base filename to which the ".DB0" and ".DBSYS1"
           extensions are appended. For example, the appropriate value for the
           default database files is /var/lib/openafs/db/prdb.

       -p <number of processes>
           Sets the number of server lightweight processes (LWPs) to run.
           Provide a positive integer from the range 3 to 16. The default
           value is 3.

           Rebuilds the Protection Database at the beginning of Protection
           Server initialization. Use this argument only in consultation with
           AFS Development or Product Support.

       -groupdepth <# of nested groups>, -depth <# of nested groups>
           Specifies the group depth for nested groups when ptserver is
           compiled with the SUPERGROUPS option enabled.  The default depth
           for nested groups is 5.  This option may be shortened to -depth.

       -default_access <user access> <group access>
           Specifies the default user and group privacy flags to apply to each
           entry. Provide a string of five characters, one for each of the
           permissions. See pts_examine(1) or pts_setfields(1) for more
           information on the flags.

           Run the PT Server in restricted mode. While in restricted mode,
           only members of the system:administrators PTS group may make any
           PTS changes.

           Activates the collection of Rx statistics and allocates memory for
           their storage. For each connection with a specific UDP port on
           another machine, a separate record is kept for each type of RPC
           (FetchFile, GetStatus, and so on) sent or received. To display or
           otherwise access the records, use the Rx Monitoring API.

           Activates the collection of Rx statistics and allocates memory for
           their storage. A separate record is kept for each type of RPC
           (FetchFile, GetStatus, and so on) sent or received, aggregated over
           all connections to other machines. To display or otherwise access
           the records, use the Rx Monitoring API.

           By default, the RXKAD security layer will disallow access by
           Kerberos principals with a dot in the first component of their
           name. This is to avoid the confusion where principals user/admin
           and user.admin are both mapped to the user.admin PTS entry. Sites
           whose Kerberos realms don’t have these collisions between principal
           names may disabled this check by starting the server with this

       -syslog[=<syslog facility>]
           Specifies that logging output should go to syslog instead of the
           normal log file.  -syslog=FACILITY can be used to specify to which
           facility the log message should be sent.  Logging message sent to
           syslog are tagged with the string "ptserver".

       -auditlog <file path>
           Specifies the full pathname for the AuditLog file.

           item -rxmaxmtu <bytes>

           Sets the maximum transmission unit for the RX protocol.

           Prints the online help for this command. All other valid options
           are ignored.


       The following bos create command creates a "ptserver" process on the
       machine "". The command appears here on multiple lines only
       for legibility.

          % bos create -server -instance ptserver \
                       -type simple -cmd /usr/lib/openafs/ptserver


       The issuer must be logged in as the superuser "root" on a file server
       machine to issue the command at a command shell prompt. It is
       conventional instead to create and start the process by issuing the bos
       create command.
