Abstract This memo defines Management Information Bases (MIBs) for performing remote ping, traceroute and lookup operations at a remote host. When managing a network it is useful to be able to initiate and retrieve the results of ping or traceroute operations when performed at a remote host. A Lookup capability is defined in order to enable resolving of either an IP address to an DNS name or an DNS name to an IP address at a remote host. Currently, there are several enterprise-specific MIBs for performing remote ping or traceroute operations. The purpose of this memo is to define a standards-based solution to enable interoperability.

Introduction 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 RFC 2119 [RFC2119]. This document is a product of the Distributed Management (DISMAN) Working Group. Its purpose is to define standards-based MIB modules for performing specific remote operations. The remote operations defined by this document consist of the ping, traceroute and lookup functions. Ping and traceroute are two very useful functions for managing networks. Ping is typically used to determine if a path exists between two hosts while traceroute shows an actual path. Both ping and traceroute yield round-trip times measured in milliseconds. These times can be used as a rough approximation for network transit time. The lookup functions considered in this document are the equivalents of gethostbyname() and gethostbyaddr(). 1.1. Ping Ping is usually implemented using the Internet Control Message Protocol (ICMP) "ECHO" facility. It is also possible to implement a ping capability using alternate methods, some of which are: o Using the UDP echo port (7), if supported. This is defined by RFC 862 [RFC862]. o Timing an SNMP query. o Timing a TCP connect attempt. In general, almost any request/response flow can be used to generate a round-trip time. Often many of the non-ICMP ECHO facility methods stand a better chance of yielding a good response (not timing out for example) since some routers don't honor Echo Requests (timeout situation) or they are handled at lower priority, hence possibly giving false indications of round trip times. It must be noted that almost any of the various methods used for generating a round-trip time can be considered a form of system attack when used excessively. Sending a system requests too often can negatively effect its performance. Attempting to connect to what is supposed to be an unused port can be very unpredictable. There are tools that attempt to connect to a range of TCP ports to test White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 3] Internet-Draft REMOPS MIB January 2004 that any receiving server can handle erroneous connection attempts. It also is important to the management application using a remote ping capability to know which method is being used. Different methods will yield different response times since the protocol and resulting processing will be different. It is RECOMMENDED that the ping capability defined within this memo be implemented using the ICMP Echo Facility. 1.2. Traceroute Traceroute is usually implemented by transmitting a series of probe packets with increasing time-to-live values. A probe packet is a UDP datagram encapsulated into an IP packet. Each hop in a path to the target (destination) host rejects the probe packet (probe's TTL too small) until its time-to-live value becomes large enough for the probe to be forwarded. Each hop in a traceroute path returns an ICMP message that is used to discover the hop and to calculate a round trip time. Some systems use ICMP probes (ICMP Echo request packets) instead of UDP ones to implement traceroute. In both cases traceroute relies on the probes being rejected via an ICMP message to discover the hops taken along a path to the final destination. Both probe types, UDP and ICMP, are encapsulated into an IP packet and thus have a TTL field that can be used to cause a path rejection. Implementations of the remote traceroute capability as defined within this memo SHOULD be done using UDP packets to a (hopefully) unused port. ICMP probes (ICMP Echo Request packets) SHOULD NOT be used. Many PC implementations of traceroute use the ICMP probe method, which they should not, since this implementation method has been known to have a high probability of failure. Intermediate hops become invisible when a router either refuses to send an ICMP TTL expired message in response to an incoming ICMP packet or simply tosses ICMP echo requests altogether. The behavior of some routers not to return a TTL expired message in response to an ICMP Echo request is due in part to the following text extracted from RFC 792 [RFC792]: "The ICMP messages typically report errors in the processing of datagrams. To avoid the infinite regress of messages about messages etc., no ICMP messages are sent about ICMP messages." 1.3. Lookup The Lookup operation enables the equivalent of either a gethostbyname() or a gethostbyaddr() call being performed at a remote host. The Lookup gethostbyname() capability can be used to determine the symbolic name of a hop in a traceroute path. White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 4] Internet-Draft REMOPS MIB January 2004 1.4. Remote Operations The MIB modules defined in this document allow a management station to initiate ping, traceroute and lookup operations remotely. The basic scenario is illustrated by the following diagram. +-------+ +-------+ +-------+ | |---------->| | | | | | initiate | |---------->| | | Mgmt. | operation |Managed| perform |Target | |Station| remotely | Node | operation | Host | | | | | | | | |<----------| | | | +-------+ receive +-------+ +-------+ result of operation A local host is the host from which the remote ping, traceroute, or Lookup operation is initiated using an SNMP request. The remote host is a host where the MIBs defined by this memo are implemented that receives the remote operation via SNMP and performs the actual ping, traceroute, or lookup function. 2. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 3. Structure of the MIBs This document defines three MIB modules: o DISMAN-PING-MIB Defines a ping MIB. White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 5] Internet-Draft REMOPS MIB January 2004 o DISMAN-TRACEROUTE-MIB Defines a traceroute MIB. o DISMAN-NSLOOKUP-MIB Provides access to the resolver gethostbyname() and gethostbyaddr() functions at a remote host. The ping and traceroute MIBs are structured to allow creation of ping or traceroute tests that can be set up to periodically issue a series of operations and generate NOTIFICATIONs to report on test results. Many network administrators have in the past written UNIX shell scripts or command batch files to operate in fashion similar to the functionality provided by the ping and traceroute MIBs defined within this memo. The intent of this document is to acknowledge the importance of these functions and to provide a standards-based solution. 3.1. Ping MIB The DISMAN-PING-MIB consists of the following components: o pingMaxConcurrentRequests o pingCtlTable o pingResultsTable o pingProbeHistoryTable 3.1.1. pingMaxConcurrentRequests The object pingMaxConcurrentRequests enables control of the maximum number of concurrent active requests that an agent implementation supports. It is permissible for an agent either to limit the maximum upper range allowed for this object or to implement this object as read-only with an implementation limit expressed as its value. 3.1.2. pingCtlTable A remote ping test is started by setting pingCtlAdminStatus to enabled(1). The corresponding pingCtlEntry MUST have been created and its pingCtlRowStatus set to active(1) prior to starting the test. A single SNMP PDU can be used to create and start a remote ping test. Within the PDU, pingCtlTargetAddress should be set to the target host's address (pingCtlTargetAddressType will default to ipv4(1)), pingCtlAdminStatus to enabled(1), and pingCtlRowStatus to createAndGo(4). White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 6] Internet-Draft REMOPS MIB January 2004 The first index element, pingCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 3415 [RFC3415], VACM) and allows a management application to identify its entries. The second index, pingCtlTestName (also an SnmpAdminString), enables the same management application to have multiple requests outstanding. Using the maximum value for the parameters defined within a pingEntry can result in a single remote ping test taking at most 15 minutes (pingCtlTimeOut times pingCtlProbeCount) plus whatever time it takes to send the ping request and receive its response over the network from the target host. Use of the defaults for pingCtlTimeOut and pingCtlProbeCount yields a maximum of 3 seconds to perform a "normal" ping test. A management application can delete an active remote ping request by setting the corresponding pingCtlRowStatus object to destroy(6). The contents of the pingCtlTable is preserved across reIPLs (Initial Program Loads) of its agent according the values of each of the pingCtlStorageType objects. 3.1.3. pingResultsTable An entry in the pingResultsTable is created for a corresponding pingCtlEntry once the test defined by this entry is started. 3.1.4. pingProbeHistoryTable The results of past ping probes can be stored in this table on a per pingCtlEntry basis. This table is initially indexed by pingCtlOwnerIndex and pingCtlTestName in order for the results of a probe to relate to the pingCtlEntry that caused it. The maximum number of entries stored in this table per pingCtlEntry is determined by the value of pingCtlMaxRows. An implementation of this MIB will remove the oldest entry in the pingProbeHistoryTable to allow the addition of an new entry once the number of rows in the pingProbeHistoryTable reaches the value specified by pingCtlMaxRows. An implementation MUST start assigning pingProbeHistoryIndex values at 1 and wrap after exceeding the maximum possible value as defined by the limit of this object ('ffffffff'h). 3.2. Traceroute MIB The DISMAN-TRACEROUTE-MIB consists of the following components: o traceRouteMaxConcurrentRequests White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 7] Internet-Draft REMOPS MIB January 2004 o traceRouteCtlTable o traceRouteResultsTable o traceRouteProbeHistoryTable o traceRouteHopsTable 3.2.1. traceRouteMaxConcurrentRequests The object traceRouteMaxConcurrentRequests enables control of the maximum number of concurrent active requests that an agent implementation supports. It is permissible for an agent either to limit the maximum upper range allowed for this object or to implement this object as read-only with an implementation limit expressed as its value. 3.2.2. traceRouteCtlTable A remote traceroute test is started by setting traceRouteCtlAdminStatus to enabled(1). The corresponding traceRouteCtlEntry MUST have been created and its traceRouteCtlRowStatus set to active(1) prior to starting the test. A single SNMP PDU can be used to create and start a remote traceroute test. Within the PDU, traceRouteCtlTargetAddress should be set to the target host's address (traceRouteCtlTargetAddressType will default to ipv4(1)), traceRouteCtlAdminStatus to enabled(1), and traceRouteCtlRowStatus to createAndGo(4). The first index element, traceRouteCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 3415 [RFC3415], VACM) and allows a management application to identify its entries. The second index, traceRouteCtlTestName (also an SnmpAdminString), enables the same management application to have multiple requests outstanding. Traceroute has a much longer theoretical maximum time for completion than ping. Basically 42 hours and 30 minutes (the product of traceRouteCtlTimeOut, traceRouteCtlProbesPerHop, and traceRouteCtlMaxTtl) plus some network transit time! Use of the defaults defined within an traceRouteCtlEntry yields a maximum of 4 minutes and 30 seconds for a default traceroute operation. Clearly 42 plus hours is too long to wait for a traceroute operation to complete. The maximum TTL value in effect for traceroute determines how long the traceroute function will keep increasing the TTL value in the probe it transmits hoping to reach the target host. The function ends whenever the maximum TTL is exceeded or the target host is reached. The object traceRouteCtlMaxFailures was created in order to White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 8] Internet-Draft REMOPS MIB January 2004 impose a throttle for how long traceroute continues to increase the TTL field in a probe without receiving any kind of response (timeouts). It is RECOMMENDED that agent implementations impose a time limit for how long it allows a traceroute operation to take relative to how the function is implemented. For example, an implementation that can't process multiple traceroute operations at the same time SHOULD impose a shorter maximum allowed time period. A management application can delete an active remote traceroute request by setting the corresponding traceRouteCtlRowStatus object to destroy(6). The contents of the traceRouteCtlTable is preserved across reIPLs (Initial Program Loads) of its agent according to the values of each of the traceRouteCtlStorageType objects. 3.2.3. traceRouteResultsTable An entry in the traceRouteResultsTable is created upon determining the results of a specific traceroute operation. Entries in this table relate back to the traceRouteCtlEntry that caused the corresponding traceroute operation to occur. The objects traceRouteResultsCurHopCount and traceRouteResultsCurProbeCount can be examined to determine how far the current remote traceroute operation has reached. 3.2.4. traceRouteProbeHistoryTable The results of past traceroute probes can be stored in this table on a per traceRouteCtlEntry basis. This table is initially indexed by traceRouteCtlOwnerIndex and traceRouteCtlTestName in order for the results of a probe to relate to the traceRouteCtlEntry that caused it. The number of entries stored in this table per traceRouteCtlEntry is determined by the value of traceRouteCtlMaxRows. An implementation of this MIB will remove the oldest entry in the traceRouteProbeHistoryTable to allow the addition of an new entry once the number of rows in the traceRouteProbeHistoryTable reaches the value of traceRouteCtlMaxRows. An implementation MUST start assigning traceRouteProbeHistoryIndex values at 1 and wrap after exceeding the maximum possible value as defined by the limit of this object ('ffffffff'h). 3.2.5. traceRouteHopsTable The current traceroute path can be stored in this table on a per traceRouteCtlEntry basis. This table is initially indexed by traceRouteCtlOwnerIndex and traceRouteCtlTestName in order for a traceroute path to relate to the traceRouteCtlEntry that caused it. White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 9] Internet-Draft REMOPS MIB January 2004 A third index, traceRouteHopsHopIndex, enables keeping one traceRouteHopsEntry per traceroute hop. Creation of traceRouteHopsTable entries is enabled by setting the corresponding traceRouteCtlCreateHopsEntries object to true(1). 3.3. Lookup MIB The DISMAN-NSLOOKUP-MIB consists of the following components: o lookupMaxConcurrentRequests, and lookupPurgeTime o lookupCtlTable o lookupResultsTable 3.3.1. lookupMaxConcurrentRequests and lookupPurgeTime The object lookupMaxConcurrentRequests enables control of the maximum number of concurrent active requests that an agent implementation is structured to support. It is permissible for an agent either to limit the maximum upper range allowed for this object or to implement this object as read-only with an implementation limit expressed as its value. The object lookupPurgeTime provides a method for entries in the lookupCtlTable and lookupResultsTable to be automatically deleted after the corresponding operation completes. 3.3.2. lookupCtlTable A remote lookup operation is initiated by performing an SNMP SET request on lookupCtlRowStatus. A single SNMP PDU can be used to create and start a remote lookup operation. Within the PDU, lookupCtlTargetAddress should be set to the entity to be resolved (lookupCtlTargetAddressType will default to ipv4(1)) and lookupCtlRowStatus to createAndGo(4). The object lookupCtlOperStatus can be examined to determine the state of an lookup operation. A management application can delete an active remote lookup request by setting the corresponding lookupCtlRowStatus object to destroy(6). An lookupCtlEntry is initially indexed by lookupCtlOwnerIndex, which is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 3415 [RFC3415], VACM) and also allows for a management application to identify its entries. The lookupCtlOwnerIndex portion of the index is then followed by lookupCtlOperationName. The lookupCtlOperationName index enables the same lookupCtlOwnerIndex entity to have multiple outstanding requests. White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 10] Internet-Draft REMOPS MIB January 2004 The value of lookupCtlTargetAddressType determines which lookup function to perform. Specification of dns(16) as the value of this index implies that the gethostbyname function should be performed to determine the numeric addresses associated with a symbolic name via lookupResultsTable entries. Use of a value of either ipv4(1) or ipv6(2) implies that the gethostbyaddr function should be performed to determine the symbolic name(s) associated with a numeric address at a remote host. 3.3.3. lookupResultsTable The lookupResultsTable is used to store the results of lookup operations. The lookupResultsTable is initially indexed by the same index elements that the lookupCtlTable contains (lookupCtlOwnerIndex and lookupCtlOperationName) but has a third index element, lookupResultsIndex (Unsigned32 textual convention), in order to associate multiple results with the same lookupCtlEntry. Both the gethostbyname and gethostbyaddr functions typically return a pointer to a hostent structure after being called. The hostent structure is defined as: struct hostent { char *h_name; /* official host name */ char *h_aliases[]; /* list of other aliases */ int h_addrtype; /* host address type */ int h_length; /* length of host address */ char **h_addr_list; /* list of address for host */ }; The hostent structure is listed here in order to address the fact that a remote host can be multi-homed and can have multiple symbolic (DNS) names. It is not intended to imply that implementations of the DISMAN-LOOKUP-MIB are limited to systems where the hostent structure is supported. The gethostbyaddr function is called with a host address as its parameter and is used primarily to determine a symbolic name to associate with the host address. Entries in the lookupResultsTable MUST be made for each host name returned. The official host name MUST be assigned a lookupResultsIndex of 1. The gethostbyname function is called with a symbolic host name and is used primarily to retrieve a host address. Normally, the first h_addr_list host address is considered to be the primary address and as such is associated with the symbolic name passed on the call. Entries MUST be stored in the lookupResultsTable in the order that they are retrieved. Values assigned to lookupResultsIndex MUST start at 1 and increase in order. White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 11] Internet-Draft REMOPS MIB January 2004 An implementation SHOULD NOT retain SNMP-created entries in the lookupTable across reIPLs (Initial Program Loads) of its agent, since management applications need to see consistent behavior with respect to the persistence of the table entries that they create. 4.

When used in conjunction with such a security policy all entries in the table belonging to a particular user (or group) will have the same value for this initial index. For a given user's entries in a particular table, the object identifiers for the information in these entries will have the same subidentifiers (except for the 'column' subidentifier) up to the end of the encoded owner index.

Security Considerations Certain management information in the MIBs defined by this document may be considered sensitive in some network environments. Therefore, authentication of received SNMP requests and controlled access to management information SHOULD be employed in such environments. The method for this authentication is a function of the SNMP Administrative Framework, and has not been expanded by this MIB. White, Quittek draft-ietf-disman-remops-mib-v2-01.txt [Page 72] Internet-Draft REMOPS MIB January 2004 To facilitate the provisioning of access control by a security administrator using the View-Based Access Control Model (VACM) defined in RFC 3415 [RFC3415] for tables in which multiple users may need to independently create or modify entries, the initial index is used as an "owner index". Such an initial index has a syntax of SnmpAdminString, and can thus be trivially mapped to a securityName or groupName as defined in VACM, in accordance with a security policy. All entries in related tables belonging to a particular user will have the same value for this initial index. For a given user's entries in a particular table, the object identifiers for the information in these entries will have the same subidentifiers (except for the "column" subidentifier) up to the end of the encoded owner index. To configure VACM to permit access to this portion of the table, one would create vacmViewTreeFamilyTable entries with the value of vacmViewTreeFamilySubtree including the owner index portion, and vacmViewTreeFamilyMask "wildcarding" the column subidentifier. More elaborate configurations are possible. The VACM access control mechanism described above provides control. In general, both the ping and traceroute functions when used excessively are considered a form of system attack. In the case of ping sending a system requests too often can negatively effect its performance or attempting to connect to what is supposed to be an unused port can be very unpredictable. Excessive use of the traceroute capability can like ping negatively affect system performance. In insecure environments it is RECOMMENDED that the MIBs defined within this memo not be supported. 6.
