                          Host Resources MIB

Status of this Memo

  This document specifies an Internet standards track protocol for the
  Internet community, and requests discussion and suggestions for
  improvements.  Please refer to the current edition of the "Internet
  Official Protocol Standards" (STD 1) for the standardization state
  and status of this protocol.  Distribution of this memo is unlimited.

Abstract

  This memo defines a portion of the Management Information Base (MIB)
  for use with network management protocols in the Internet community.
  This memo obsoletes RFC 1514, the "Host Resources MIB". This memo
  extends that specification by clarifying changes based on
  implementation and deployment experience and documenting the Host
  Resources MIB in SMIv2 format while remaining semantically identical
  to the existing SMIv1-based MIB.

  This memo defines a MIB for use with managing host systems.  The term
  "host" is construed to mean any computer that communicates with other
  similar computers attached to the internet and that is directly used
  by one or more human beings. Although this MIB does not necessarily
  apply to devices whose primary function is communications services
  (e.g., terminal servers, routers, bridges, monitoring equipment),
  such relevance is not explicitly precluded.  This MIB instruments
  attributes common to all internet hosts including, for example, both
  personal computers and systems that run variants of Unix.

1.  The SNMP Management Framework

  The SNMP Management Framework presently consists of five major
  components:

  o   An overall architecture, described in RFC 2571 [RFC2571].

  o   Mechanisms for describing and naming objects and events for the
      purpose of management. The first version of this Structure of
      Management Information (SMI) is called SMIv1 and described in STD
      16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215
      [RFC1215]. The second version, called SMIv2, is described in STD
      58, RFC 2578 [RFC2578], RFC 2579 [RFC2579] and RFC 2580
      [RFC2580].

  o   Message protocols for transferring management information. The
      first version of the SNMP message protocol is called SNMPv1 and
      described in STD 15, RFC 1157 [RFC1157]. A second version of the
      SNMP message protocol, which is not an Internet standards track
      protocol, is called SNMPv2c and described in RFC 1901 [RFC1901]
      and RFC 1906 [RFC1906]. The third version of the message protocol
      is called SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572
      [RFC2572] and RFC 2574 [RFC2574].




Waldbusser & Grillo         Standards Track                     [Page 2]

RFC 2790                   Host Resources MIB                 March 2000


  o   Protocol operations for accessing management information. The
      first set of protocol operations and associated PDU formats is
      described in STD 15, RFC 1157 [RFC1157]. A second set of protocol
      operations and associated PDU formats is described in RFC 1905
      [RFC1905].

  o   A set of fundamental applications described in RFC 2573 [RFC2573]
      and the view-based access control mechanism described in RFC 2575
      [RFC2575].

  A more detailed introduction to the current SNMP Management Framework
  can be found in RFC 2570 [RFC2570].

  Managed objects are accessed via a virtual information store, termed
  the Management Information Base or MIB.  Objects in the MIB are
  defined using the mechanisms defined in the SMI.

  This memo specifies a MIB module that is compliant to the SMIv2. A
  MIB conforming to the SMIv1 can be produced through the appropriate
  translations. The resulting translated MIB must be semantically
  equivalent, except where objects or events are omitted because no
  translation is possible (use of Counter64). Some machine readable
  information in SMIv2 will be converted into textual descriptions in
  SMIv1 during the translation process.  However, this loss of machine
  readable information is not considered to change the semantics of the
  MIB.

2.  Host Resources MIB

  The Host Resources MIB defines a uniform set of objects useful for
  the management of host computers.  Host computers are independent of
  the operating system, network services, or any software application.

  The Host Resources MIB defines objects which are common across many
  computer system architectures.

  In addition, there are objects in the SNMPv2-MIB [RFC1907] and IF-MIB
  [RFC2233] which also provide host management functionality.
  Implementation of the System and Interfaces groups is mandatory for
  implementors of the Host Resources MIB.

  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
  "SHOULD", "SHOULD NOT", "RECOMMENDED","MAY", and "OPTIONAL" in this
  document are to be interpreted as described in [RFC2119].

3.  IANA Considerations

  This MIB contains type definitions for storage types, device types,
  and file system types for use as values for the hrStorageType,
  hrDeviceType, and hrFSType objects, respectively. As new computing
  technologies are developed, new types need to be registered for these
  technologies. The IANA (Internet Assigned Numbers Authority) is
  designated as the registration authority for new registrations beyond
  those published in this document. The IANA will maintain the HOST-
  RESOURCES-TYPES module as new registrations are added and publish new
  versions of this module.

  Given the large number of such technologies and potential confusion
  in naming of these technologies (such as a technology known by two
  names or a name and an acronym), there is a real danger that more
  than one registration might be created for what is essentially the
  same technology. In order to ensure that future type registrations
  are performed correctly, applications for new types will be reviewed
  by a Designated Expert appointed by the IESG.

          An entry shall be placed in the storage table for each
          logical area of storage that is allocated and has
          fixed resource limits.  The amount of storage
          represented in an entity is the amount actually usable
          by the requesting entity, and excludes loss due to
          formatting or file system reference information.

          These entries are associated with logical storage
          areas, as might be seen by an application, rather than
          physical storage entities which are typically seen by
          an operating system.  Storage such as tapes and
          floppies without file systems on them are typically
          not allocated in chunks by the operating system to
          requesting applications, and therefore shouldn't
          appear in this table.  Examples of valid storage for
          this table include disk partitions, file systems, ram
          (for some architectures this is further segmented into
          regular memory, extended memory, and so on), backing
          store for virtual memory (`swap space').

          This table is intended to be a useful diagnostic for
          `out of memory' and `out of buffers' types of
          failures.  In addition, it can be a useful performance

6.  Internationalization Considerations

  This MIB has many objects that identify file-system pathnames on the
  managed host. Many file systems allow pathnames to be encoded in a
  variety of character sets (other than ASCII), but do not support the
  encoding of the actual character set used with the pathname. The
  implementation strategy is that user interfaces (i.e. character-based
  shells or graphical applications) will have configuration options
  that control with which character set they will interpret and display
  all pathnames. This is often a per-user configuration (e.g. an
  environment variable), so that users using different languages and
  character sets on a multi-user system may each work effectively with
  their preferred character set. A human usually controls this
  configuration. If an application is not configured or is configured
  incorrectly, it will often have trouble displaying pathnames in the
  intended character set.

  This situation made it important for this MIB to handle two issues:

  1) Pathname objects must be able to transfer a variety of character
     sets with potentially multi-byte encodings; and,







Waldbusser & Grillo         Standards Track                    [Page 44]

RFC 2790                   Host Resources MIB                 March 2000


  2) HostMIB agents will generally not be correctly configured for the
     appropriate character set to be used for all files on the system,
     particularly on a system with multiple users using different
     character sets. It was thus impossible to mandate that the agent
     tag pathnames with the character set in use.

  These issues were solved with the introduction of the
  InternationalDisplayString textual convention, which supports multi-
  byte encodings. Network management stations should use a local
  algorithm to determine which character set is in use and how it
  should be displayed. It is expected that network management station
  applications will rely on human configuration to choose which
  character set in which to interpret InternationalDisplayString
  objects, much like an application running locally on that host.

7.  Security Considerations

  There are a number of management objects defined in this MIB that
  have a MAX-ACCESS clause of read-write.  Such objects may be
  considered sensitive or vulnerable in some network environments.  The
  support for SET operations in a non-secure environment without proper
  protection can have a negative effect on system operations.

  There are a number of managed objects in this MIB that may contain
  sensitive information. The objects in the Running Software Group list
  information about running software on the system (including the
  operating system software and version).  Some may wish not to
  disclose to others what software they are running. Further, an
  inventory of the running software and versions may be helpful to an
  attacker who hopes to exploit software bugs in certain applications.
  The same issues exist for the objects in the Installed Software
  Group.

  It is thus important to control even GET access to these objects and
  possibly to even encrypt the values of these object when sending them
  over the network via SNMP.  Not all versions of SNMP provide features
  for such a secure environment.

  SNMPv1 by itself is not a secure environment.  Even if the network
  itself is secure (for example by using IPSec), even then, there is no
  control as to who on the secure network is allowed to access and
  GET/SET (read/change/create/delete) the objects in this MIB.

  It is recommended that the implementers consider the security
  features as provided by the SNMPv3 framework.  Specifically, the use
  of the User-based Security Model RFC 2574 [RFC2574] and the View-
  based Access Control Model RFC 2575 [RFC2575] is recommended.




Waldbusser & Grillo         Standards Track                    [Page 45]

RFC 2790                   Host Resources MIB                 March 2000


  It is then a customer/user responsibility to ensure that the SNMP
  entity giving access to an instance of this MIB, is properly
  configured to give access to the objects only to those principals
  (users) that have legitimate rights to indeed GET or SET
  (change/create/delete) them.
