[-audit-interface (file | sysvmq)]
[-syslog[=<FACILITY>]] [-rxmaxmtu <bytes>]

DESCRIPTION
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
database.
* 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
belongs.
When using Kerberos 5, cross-realm authentication is possible. If the
special pts group system:[email protected] 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:[email protected] PTS group. Each time a foreign
user is created in the local PTS database, the group quota for the
system:[email protected] 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.
OPTIONS
-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 threads>
Sets the number of server lightweight processes (LWPs or pthreads)
to run. Provide a positive integer from the range 3 to 16. The
default value is 3.
-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.
-restricted
Run the PT Server in restricted mode. While in restricted mode,
only members of the system:administrators PTS group may make any
PTS changes.
-enable_peer_stats
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.
-enable_process_stats
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.
-allow-dotted-principals
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 disable this check by starting the server with this
option.
-rxbind
Bind the Rx socket to the primary interface only. (If not
specified, the Rx socket will listen on all interfaces.)
-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 <log path>
Turns on audit logging, and sets the path for the audit log. The
audit log records information about RPC calls, including the name
of the RPC call, the host that submitted the call, the
authenticated entity (user) that issued the call, the parameters
for the call, and if the call succeeded or failed.
-audit-interface (file | sysvmq)
Specifies what audit interface to use. Defaults to "file". See
fileserver(8) for an explanation of each interface.
-rxmaxmtu <bytes>
Sets the maximum transmission unit for the RX protocol.
-help
Prints the online help for this command. All other valid options
are ignored.
EXAMPLES
The following bos create command creates a "ptserver" process on the
machine "fs3.abc.com". The command appears here on multiple lines only
for legibility.
% bos create -server fs3.abc.com -instance ptserver \
-type simple -cmd /usr/lib/openafs/ptserver
PRIVILEGE REQUIRED
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.
