SYNOPSIS

ptserver [-database <db path>] [-p <number of processes>]
[-d <debug level>]
    [-rebuildDB] [-groupdepth <# of nested groups>]
    [-default_access <user access mask> <group access mask>]
    [-restricted] [-enable_peer_stats]
    [-enable_process_stats] [-allow-dotted-principals]
    [-auditlog <file path>]
    [-syslog[=<FACILITY>]] [-rxmaxmtu <bytes>]
    [-help]

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:

o Maintains the Protection Database, which contains entries for every
user and group in the cell. Use the pts commands to administer the database.
o Allocates AFS IDs for new user, machine and group entries and maps
each ID to the corresponding name.
o 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: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.

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 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.
-rebuildDB
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.
-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 disabled this check by starting the server with this
option.
-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.
-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.
