fns_references - Overview of FNS References
Every composite
name in FNS is bound to a reference. A reference consists of a type and
a list of addresses. The reference type is used to identify the type of
object.
An address is something that can be used with some communication
mechanism to invoke operations on an object or service. Multiple addresses
are intended to identify multiple communication endpoints for a single
conceptual object or service. Each address in a reference consists of an
address type and an opaque buffer. The address type determines the format
and interpretation of the address data. Together, the address’s type and
data specify how to reach the object. Many communication mechanisms are
possible; FNS does not place any restrictions on them.
The following summarizes
the reference and address types that are currently defined. New types should
be registered with the Federated Naming Group at SunSoft.
All
reference types use the FN_ID_STRING
identifier format unless otherwise
qualified.
- onc_fn_enterprise
- Enterprise root context.
- onc_fn_organization
- A context for naming objects related to an organizational unit.
- onc_fn_hostname
- A context for naming hosts.
- onc_fn_username
- A context for naming users.
- onc_fn_user
- A context for naming objects related to a user.
- onc_fn_host
- A context for
naming objects related to a computer.
- onc_fn_site
- A context for naming sites.
- onc_fn_service
- A context for naming services.
- onc_fn_nsid
- A context for
naming namespace identifiers.
- onc_fn_generic
- A context for naming application-specific
objects.
- onc_fn_fs
- A context for naming files, directories, and file systems.
- onc_fn_printername
- A context for naming printers.
- onc_printers
- A printer
object. When implemented on top of NIS+, this could also be a context for
naming printers.
- onc_fn_null
- A null context.
- fn_link_ref
- An XFN link.
- inet_domain
- An Internet domain.
All address types use the FN_ID_STRING
identifier format unless otherwise qualfied. The format of address contents
is determined by the corresponding address type.
- onc_fn_nisplus
- For an FNS
enterprise-level object implemented on top of NIS+. The address contains
the context type, context representation type (either normal or merged),
version number of the reference, and the NIS+ name of the object. The only
intended use of this reference is that it be passed to fn_ctx_handle_from_ref().
- onc_fn_nis
- For an FNS enterprise-level object implemented on top of NIS.
The address contains the context type and version number of the reference,
and the NIS name of the object. The only intended use of this reference
is that it be passed to fn_ctx_handle_from_ref().
- onc_fn_files
- For an FNS
enterprise-level object implemented on top of /etc files. The address contains
the context type and version number of the reference, and the location
of the object in the /etc file system. The only intended use of this reference
is that it be passed to fn_ctx_handle_from_ref().
- onc_fn_fs_user_nisplus
- For a user’s home directory. The address contains the user’s name and the
name of the NIS+ passwd table where the user’s home directory is stored.
- onc_fn_fs_host
- For all file systems exported by a host. The address contains
the host’s name.
- onc_fn_fs_mount
- For a single mount point. The address contains
the mount options, the name of the servers and the exported path. See mount(1M)
.
- fn_link_addr
- For an XFN link address. The contents is the string form
of the composite name.
- inet_domain
- For an Internet domain. The address contains
the fully-qualified domain name (e.g. "Wiz.COM.")
- inet_ipaddr_string
- For an
object with an Internet address. The address contains an internet IP address
in dotted string form (e.g. "192.144.2.3").
- x500
- For an X.500 object. The address
contains an X.500 Distinguished Name, in the syntax specified in the X/Open
DCE: Directory Services.
- osi_paddr
- For an object with an OSI presentation
address. The address contains the string encoding of an OSI Presentation
Address as defined in RFC 1278.
- onc_printers_bsaddr
- For a printer that
understands the BSD print protocol. The address contains the machine name
and printer name used by the protocol.
- onc_printers_use
- For a printer alias.
The address contains a printer name.
- onc_printers_all
- For a list of printers
that are enumerated using the "all" option. The address contains a list
of printer names.
- onc_printers_location
- For a printer’s location. The address
format is unspecified.
- onc_printers_type
- For a printer’s type. The address
format is unspecified.
- onc_printers_speed
- For a printer’s speed. The address
format is unspecified.
