DESCRIPTION
The pts examine command displays information from the Protection Database entry of each
user, machine or group specified by the -nameorid argument.
OPTIONS
-nameorid <user or group name or id>+
Specifies the name or AFS UID of each user, the name or AFS GID of each group, or the
IP address (complete or wildcard-style) or AFS UID of each machine for which to
display the Protection Database entry. It is acceptable to mix users, machines, and
groups on the same command line, as well as names (IP addresses for machines) and IDs.
Precede the GID of each group with a hyphen to indicate that it is negative.
-auth
Run using the user's current authentication. This is the default unless the -noauth or
-localauth options are used.
-cell <cell name>
Names the cell in which to run the command. For more details, see pts(1).
-force
Enables the command to continue executing as far as possible when errors or other
problems occur, rather than halting execution at the first error.
-help
Prints the online help for this command. All other valid options are ignored.
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile
file. Do not combine this flag with the -cell or -noauth options. For more details,
see pts(1).
-noauth
Assigns the unprivileged identity anonymous to the issuer. For more details, see
pts(1).
OUTPUT
The output for each entry consists of two lines that include the following fields:
Name
The contents of this field depend on the type of entry:
• For a user entry, it is the username that the user types when authenticating with
AFS.
• For a machine entry, it is either the IP address of a single machine in dotted
decimal format, or a wildcard notation that represents a group of machines on the
same network. See the pts createuser reference page for an explanation of the
wildcard notation.
• For a group entry, it is one of two types of group name. If the name has a colon
between the two parts, it represents a regular group and the part before the
prefix reflects the group's owner. A prefix-less group does not have the owner
field or the colon. For more details on group names, see the pts creategroup
reference page.
id A unique number that the AFS server processes use to identify AFS users, machines and
groups. AFS UIDs for user and machine entries are positive integers, and AFS GIDs for
group entries are negative integers. AFS UIDs and GIDs are similar in function to the
UIDs and GIDs used in local file systems such as UFS, but apply only to AFS
operations.
owner
The user or group that owns the entry and thus can administer it (change the values in
most of the fields displayed in the output of this command), or delete it entirely.
The Protection Server automatically records the system:administrators group in this
field for user and machine entries at creation time.
creator
The user who issued the pts createuser or pts creategroup command to create the entry.
This field serves as an audit trail, and cannot be changed.
membership
An integer that for users and machines represents the number of groups to which the
user or machine belongs. For groups, it represents the number of group members.
flags
A string of five characters, referred to as privacy flags, which indicate who can
display or administer certain aspects of the entry.
s Controls who can issue the pts examine command to display the entry.
o Controls who can issue the pts listowned command to display the groups that a user
or group owns.
m Controls who can issue the pts membership command to display the groups a user or
machine belongs to, or which users or machines belong to a group.
a Controls who can issue the pts adduser command to add a user or machine to a
group. It is meaningful only for groups, but a value must always be set for it
even on user and machine entries.
r Controls who can issue the pts removeuser command to remove a user or machine from
a group. It is meaningful only for groups, but a value must always be set for it
even on user and machine entries.
Each flag can take three possible types of values to enable a different set of users
to issue the corresponding command:
• A hyphen (-) designates the members of the system:administrators group and the
entry's owner. For user entries, it designates the user in addition.
• The lowercase version of the letter applies meaningfully to groups only, and
designates members of the group in addition to the individuals designated by the
hyphen.
• The uppercase version of the letter designates everyone.
For example, the flags "SOmar" on a group entry indicate that anyone can examine the
group's entry and display the groups that it owns, and that only the group's members
can display, add, or remove its members.
The default privacy flags for user and machine entries are "S----", meaning that
anyone can display the entry. The ability to perform any other functions is restricted
to members of the system:administrators group and the entry's owner (as well as the
user for a user entry).
The default privacy flags for group entries are "S-M--", meaning that all users can
display the entry and the members of the group, but only the entry owner and members
of the system:administrators group can perform other functions. The defaults for the
privacy flags may be changed by running ptserver with the -default_access option. See
ptserver(8) for more discussion of the -default_access option.
group quota
The number of additional groups the user is allowed to create. The pts createuser
command sets it to 20 for both users and machines, but it has no meaningful
interpretation for a machine, because it is not possible to authenticate as a machine.
Similarly, it has no meaning in group entries that only deal with the local cell and
the pts creategroup command sets it to 0 (zero); do not change this value.
When using cross-realm authentication, a special group of the form
system:authuser@FOREIGN.REALM is created by an administrator and used. If the group
quota for this special group is greater than zero, then aklog will automatically
register foreign users in the local PTS database, add the foreign user to the
system:authuser@FOREIGN.REALM, and decrement the group quota by one.
EXAMPLES
The following example displays the user entry for "terry" and the machine entry
158.12.105.44.
% pts examine terry 158.12.105.44
Name: terry, id: 1045, owner: system:administrators, creator: admin,
membership: 9, flags: S----, group quota: 15.
Name: 158.12.105.44, id: 5151, owner: system:administrators,
creator: byu, membership: 1, flags: S----, group quota: 20.
The following example displays the entries for the AFS groups with GIDs -673 and -674.
% pts examine -673 -674
Name: terry:friends, id: -673, owner: terry, creator: terry,
membership: 5, flags: S-M--, group quota: 0.
Name: smith:colleagues, id: -674, owner: smith, creator: smith,
membership: 14, flags: SOM--, group quota: 0.
PRIVILEGE REQUIRED
The required privilege depends on the setting of the first privacy flag in the Protection
Database entry of each entry specified by the -nameorid argument:
• If it is lowercase "s", members of the system:administrators group and the user
associated with a user entry can examine it, and only members of the
system:administrators group can examine a machine or group entry.
• If it is uppercase "S", anyone who can access the cell's database server machines can
examine the entry.
