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:
o For a user entry, it is the username that the user types when authenticating with AFS.
o 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.
o 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:
o A hyphen (-) designates the members of the system:administrators group and the entry's owner. For user entries, it designates the
user in addition.
o 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.
o 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:
o 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.
o If it is uppercase "S", anyone who can access the cell's database server machines can examine the entry.
