This is the command snmpwalk that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
snmpwalk - retrieve a subtree of management values using SNMP GETNEXT requests
SYNOPSIS
snmpwalk [APPLICATION OPTIONS] [COMMON OPTIONS] AGENT [OID]
DESCRIPTION
snmpwalk is an SNMP application that uses SNMP GETNEXT requests to query a network entity
for a tree of information.
An object identifier (OID) may be given on the command line. This OID specifies which
portion of the object identifier space will be searched using GETNEXT requests. All
variables in the subtree below the given OID are queried and their values presented to the
user. Each variable name is given in the format specified in variables(5).
If no OID argument is present, snmpwalk will search the subtree rooted at
SNMPv2-SMI::mib-2 (including any MIB object values from other MIB modules, that are
defined as lying within this subtree). If the network entity has an error processing the
request packet, an error packet will be returned and a message will be shown, helping to
pinpoint why the request was malformed.
If the tree search causes attempts to search beyond the end of the MIB, the message "End
of MIB" will be displayed.
OPTIONS
-Cc Do not check whether the returned OIDs are increasing. Some agents (LaserJets are
an example) return OIDs out of order, but can complete the walk anyway. Other
agents return OIDs that are out of order and can cause snmpwalk to loop
indefinitely. By default, snmpwalk tries to detect this behavior and warns you
when it hits an agent acting illegally. Use -Cc to turn off this check.
-CE {OID}
End the walk at the specified OID, rather than a simple subtree. This can be used
to walk a partial subtree, selected columns of a table, or even two or more tables
within a single command.
-Ci Include the given OID in the search range. Normally snmpwalk uses GETNEXT
requests starting with the OID you specified and returns all results in the MIB
subtree rooted at that OID. Sometimes, you may wish to include the OID specified
on the command line in the printed results if it is a valid OID in the tree
itself. This option lets you do this explicitly.
-CI In fact, the given OID will be retrieved automatically if the main subtree walk
returns no useable values. This allows a walk of a single instance to behave as
generally expected, and return the specified instance value. This option turns
off this final GET request, so a walk of a single instance will return nothing.
-Cp Upon completion of the walk, print the number of variables found.
-Ct Upon completion of the walk, print the total wall-clock time it took to collect
the data (in seconds). Note that the timer is started just before the beginning
of the data request series and stopped just after it finishes. Most importantly,
this means that it does not include snmp library initialization, shutdown,
argument processing, and any other overhead.
In addition to these options, snmpwalk takes the common options described in the
snmpcmd(1) manual page.
EXAMPLES
Note that snmpwalk REQUIRES an argument specifying the agent to query and at most one OID
argument, as described there. The command:
snmpwalk -Os -c public -v 1 zeus system
will retrieve all of the variables under system:
sysDescr.0 = STRING: "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
sysObjectID.0 = OID: enterprises.hp.nm.hpsystem.10.1.1
sysUpTime.0 = Timeticks: (155274552) 17 days, 23:19:05
sysContact.0 = STRING: ""
sysName.0 = STRING: "zeus.net.cmu.edu"
sysLocation.0 = STRING: ""
sysServices.0 = INTEGER: 72
(plus the contents of the sysORTable).
The command:
snmpwalk -Os -c public -v 1 -CE sysORTable zeus system
will retrieve the scalar values, but omit the sysORTable.
