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]. 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.

STATUS current
DESCRIPTION
"This textual convention is intended to identify the
-
-
-
manufacturer, model, and version of a specific hardware or software product. It is suggested that these OBJECT IDENTIFIERs are allocated such that all products from a particular manufacturer are registered under a subtree distinct to that manufacturer. In addition, all versions of a product should be registered under a subtree distinct to that product. With this strategy, a management station may uniquely determine the manufacturer and/or model of a product whose productID is unknown to the management station. Objects of this type may be useful for inventory purposes or for automatically detecting incompatibilities or version mismatches between various hardware and software components on a system.
-
-
For example, the product ID for the ACME 4860 66MHz
clock doubled processor might be:
enterprises.acme.acmeProcessors.a4860DX2.MHz66
-
A software product might be registered as: enterprises.acme.acmeOperatingSystems.acmeDOS.six(6).one(1) " SYNTAX OBJECT IDENTIFIER-- unknownProduct will be used for any unknown ProductID -- unknownProduct OBJECT IDENTIFIER ::= { 0 0 }

A network management station should use a local algorithm to determine which character set is in use and how it should be displayed. Note that this character set may be encoded with more than one octet per symbol, but will most often be NVT ASCII.

-
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').

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