.Sh DESCRIPTION
|
||||||
|
.Nm ,
|
||||||
|
.Nm bsnmpwalk
|
||||||
|
and
|
||||||
|
.Nm bsnmpset
|
||||||
|
are simple tools for retrieving management information from and setting
|
||||||
|
management information to a Simple Network Managment Protocol (SNMP) agent.
|
||||||
|
.Pp
|
||||||
|
Depending on the options
|
||||||
|
.Nm bsnmpget
|
||||||
|
constructs either a SMNP GetRequest, GetNextRequest
|
||||||
|
or a GetBulkRequest packet, fills in the object identifiers (OIDs) of the
|
||||||
|
objects whose values will be retrived, waits for a response and prints it if
|
||||||
|
received successfully.
|
||||||
|
.Pp
|
||||||
|
.Nm Bsnmpwalk
|
||||||
|
queries an agent with SMNP GetNextRequest packets,
|
||||||
|
asking for values of OID instances that are a part of the object subtree
|
||||||
|
rooted at the provided OIDs.
|
||||||
|
.Pp
|
||||||
|
.Nm Bsnmpset
|
||||||
|
constructs a SMNP SetRequest packet, fills in the OIDs (object identifiers),
|
||||||
|
syntaxes and values of the objects whose values are to be set and waits for a
|
||||||
|
responce from server.
|
||||||
|
.Sh OPTIONS
|
||||||
|
.Pp
|
||||||
|
The options are as follows (not all apply to all three programs):
|
||||||
|
.Bl -tag -width ".It Fl D Ar options"
|
||||||
|
.It Fl A Ar options
|
||||||
|
Authentication options to use with SNMPv3 PDUs
|
||||||
|
.Bl -tag -width
|
||||||
|
.It Cm proto=[md5|sha]
|
||||||
|
The protocol to use when calculating the PDU message digest.
|
||||||
|
.It Cm key=authkey
|
||||||
|
A binary localized authentication key to use when calculating the PDU message
|
||||||
|
digest.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
By default SNMPv3 PDUs are sent unauthenticated.
|
||||||
|
.It Fl a
|
||||||
|
Skip any sanity checks when adding OIDs to a Protocol Data Unit (PDU):
|
||||||
|
ingore syntax/access type, allow adding of non-leaf objects for GetPdu and
|
||||||
|
read-only objects to a SetPDU.
|
||||||
|
.It Fl b Ar buffersize
|
||||||
|
Tune the size of buffers used to send and receive packets.
|
||||||
|
The default size is 10000 bytes which should be enough unless an agent sends
|
||||||
|
a really large octetstring.
|
||||||
|
The maximum allowed length is 65535 according to the Structure of Management
|
||||||
|
Information (SMIv2).
|
||||||
|
.It Fl C Ar options
|
||||||
|
The context to query with SNMPv3 PDUs.
|
||||||
|
.Bl -tag -width
|
||||||
|
.It Cm context=name
|
||||||
|
The context name. Default is "" (empty).
|
||||||
|
.It Cm context-engine=engine-id
|
||||||
|
The SNMP Engine ID of the context to query with SNMPv3 PDUs, represented as
|
||||||
|
binary octet string. By default, this is set to the Engine ID of the SNMP agent.
|
||||||
|
.El
|
||||||
|
.It Fl D
|
||||||
|
Perform SNMP USM Engine Discovery, rather than sending a request for the value
|
||||||
|
of a specific object.
|
||||||
|
.It Fl d
|
||||||
|
Turn on debugging.
|
||||||
|
This option will cause the packets sent and received to be dumped to the
|
||||||
|
terminal.
|
||||||
|
.It Fl e
|
||||||
|
Retry on error.
|
||||||
|
If an error is returned in the response PDU, resend the request removing the
|
||||||
|
variable that caused the error until a valid response is received.
|
||||||
|
This is only usefull for a GetRequest- and a GetNextRequest-PDU.
|
||||||
|
.It Fl h
|
||||||
|
Print a short help text with default values for various options.
|
||||||
|
.It Fl I Ar options
|
||||||
|
Load each MIB description file from the given list to translate symbolic
|
||||||
|
object names to their numerical representation and vice versa.

Use the other options to obtain a non-default behaviour:
|
||||||
|
.Bl -tag -width
|
||||||
|
.It Cm cut=OID
|
||||||
|
Specifies the initial OID that was cut by
|
||||||
|
.Xr gensnmpdef 1
|
||||||
|
when producing the MIB description file.
|
||||||
|
The default value is .iso(1).org(3).dod(6) which is what should have been
|
||||||
|
used for all the files installed under /usr/share/snmp/defs/ .
|
||||||
|
Use this only if you generated your own files, providing a '-c' option to
|
||||||
|
.Xr gensnmpdef 1 .
|
||||||
|
.It Cm path=filedir
|
||||||
|
The directory where files in the list will be searched.
|
||||||
|
The default is
|
||||||
|
.Pa /usr/share/snmp/defs/ .
|
||||||
|
.It Cm file=filelist
|
||||||
|
A comma separated list of files to which the two options above will apply.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The file suboption has to come after the other suboptions so that their
|
||||||
|
non-default values will be applied to the list of files.
|
||||||
|
The order of the other suboptions before each file suboption can be random.
|
||||||
|
Suboptions may be separated either by commas or by spaces.
|
||||||
|
If using spaces make sure the entire option string is one argument, for
|
||||||
|
example using quotes.
|
||||||
|
.It Fl i Ar filelist
|
||||||
|
List of MIB description files produced by
|
||||||
|
.Xr gensnmpdef 1 which
|

|
||||||
|
.Nm bsnmpwalk
|
||||||
|
or
|
||||||
|
.Nm bsnmpset
|
||||||
|
will search to translate numerical OIDs to their symbolic object names.
|
||||||
|
Multiple files can be provided either giving this option multiple times
|
||||||
|
or a comma separated list of file names.
|
||||||
|
If a filename begins with a letter the default directory,
|
||||||
|
/usr/share/snmp/defs/ ,
|
||||||
|
will be searched.
|
||||||
|
.It Fl K
|
||||||
|
Calculate and display the localized authentication and privacy keys
|
||||||
|
corresponding to a plain text password. The password is obtain via the
|

|
||||||
|
keys are used when processing the SNMPv3 requests.
|
||||||
|
.It Fl l Ar filename
|
||||||
|
The path of the posix local (unix domain) socket if local
|
||||||
|
transport is used.
|
||||||
|
.It Fl M Ar max-repetitions

||||||
|
The value for the max-repetitions field in a GetBulk PDU.
|
||||||
|
Default is 1.
|
||||||
|
.It Fl N Ar non-repeaters
|
||||||
|
The value for the non-repeaters field in a GetBulk PDU.

|
||||||
|
Note that

||||||
|
.Nm bsnmpget ,
|
||||||
|
.Nm bsnmpwalk
|
||||||
|
and
|
||||||
|
.Nm bsnmpset
|
||||||
|
will print numerical OIDs anyway if the corresponding string representation
|
||||||
|
is not found in the MIB description files.
|
||||||
|
.It Fl o Ar [quiet|short|verbose]
|
||||||
|
The format used to print the received response.
|
||||||
|
Quiet only prints values, short (default) prints an abbreviated OID
|
||||||
|
representation and the value.
|
||||||
|
In addition to the short output verbose prints the type before the value.
|
||||||
|
.It Fl P Ar options

Default is 3.
|
||||||
|
.It Fl s Ar [trans::] Ns Ar [community@] Ns Ar [server] Ns Ar [:port]
|
||||||
|
Each of the server specification components is optional but at least one

||||||
|
has to be provided if '-s' option is used.
|
||||||
|
The server specification is constructed in the following manner:
|
||||||
|
.Bl -tag -width
|
||||||
|
.It Cm trans::
|
||||||
|
Transport type may be one of udp, stream or dgram.

|
If this option is not provided an udp inet/inet6 socket will be used, which
|
||||||
|
is the most common.
|

|
socket will be used if dgram is specified.
|
||||||
|
.It Cm community@

|
||||||
|
If the option is skipped the default "public" will be used for
|
||||||
|
.Nm
|
||||||
|
and
|
||||||
|
.Nm bsnmpwalk
|
||||||
|
and the default "private" community string will be used for

||||||
|
The default is 'localhost'.
|
||||||
|
.It Cm port
|
||||||
|
The destination port to send the requests to.
|
||||||
|
This is useful if the SNMP agent listens on a non-default port.

|
||||||
|
.El
|
||||||

|
||||||
|
User credentials when sending SNMPv3 PDUs.
|
||||||
|
.Bl -tag -width

||||||
|
.It Cm engine-time=value
|
||||||
|
The value of the snmpEngineTime of the SNMP agent.
|
||||||
|
.Pp
|
||||||
|
If any of the above is not specified, SNMP USM Engine Discovery is attempted.
|
||||||
|
This is also the default behavior.
|
||||||
|
.It Cm name=username
|
||||||
|
The USM user name to include in the SNMPv3 PDUs. By default, the user name is
|
||||||
|
obtain via the environment

3 are supported.
|
||||||
|
If no version option is provided
|
||||||
|
.Nm bsnmpget ,
|
||||||
|
.Nm bsnmpwalk
|
||||||
|
and
|

|
.Nm bsnmpset
|
||||||
|
will use version 2.
|
||||||

||||||
|
version to 1 is incompatiable with sending a GetBulk PDU.
|
||||||
|
.It OID
|
||||||
|
The object identifier whose value to retrive.
|
||||||
|
At least one OID should be provided for

||||||
|
For
|
||||||
|
.Nm bsnmpwalk
|
||||||
|
this is the root object identifier of the subtree whose values are to be
|
||||||
|
retrived.
|
||||||
|
If no OID is provided
|
||||||
|
.Nm bsnmpwalk
|
||||||
|
will walk the mib2 subtree rooted
|
||||||
|
at .iso(1).org(3).dod(6).internet(1).mgmt(2).mib2(1) .
|
||||||
|
.Pp
|
||||||
|
Any of the formats used to print a single variable
|
||||||
|
is valid as input OID:
|
||||||
|
.Bl -tag -width
|
||||||
|
.It 1.3.6.1.2.1.25.1.1.0
|
||||||
|
.It sysDescr
|
||||||
|
.It ifPhysAddress.1
|
||||||
|
.It ifRcvAddressStatus.2.6.255.255.255.255.255.255
|
||||||
|
.It ifRcvAddressType[2,ff:ff:ff:ff:ff:ff]
|
||||||
|
.It ifRcvAddressStatus[Integer:1,OctetString:ff:ff:ff:ff:ff:ff]
|
||||||
|
(requires '-o verbose' option)
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
Square brackets are used to denote an entry's indexes.
|
||||||
|
When used in an input OID, the square brackets may have to be
|
||||||
|
escaped or the OID has to be quoted to protect it from the shell.
|
||||||
|
Note there is no difference between ifName.1 and "ifName[1]".
|
||||||
|
.It OID Ns = Ns Ar [syntax Ns :] Ns Ar value
|
||||||
|
The object identifier with its syntax type and value that is to be set.
|
||||||
|
At least one such string OID=[syntax:]value should be provided to
|
||||||
|
.Nm bsnmpset
|
||||||
|
to be able to send a request.
|
||||||
|
.Bl -tag -width
|
||||||
|
.It Cm OID
|
||||||
|
OID may be input as a string, a string followed by a random number of integers
|
||||||
|
(suboids) separated by dots, a sequence of integers separated by dots - that is
|
||||||
|
if '-n' options is used - and in such case a syntax is required for every value,
|
||||||
|
or a string followed by square brackets (used to denote an entry's indexes) and
|
||||||
|
corresponding indexes.
|
||||||
|
Any of formats used to print a single variable by
|
||||||
|
.Nm bsnmpset is
|
||||||
|
valid for inpit OID as well:
|
||||||
|
.Bl -tag -width
|
||||||
|
.It 1.3.6.1.2.1.25.1.1.0=TimeTicks:537615486
|
||||||
|
.It sysLocation=OctetString:"@ Home" (with '-o verbose' option)
|

|
||||||
|
(with '-o verbose' option)
|

|
.El
|
||||||
|
.It Cm syntax
|
||||||
|
where syntax string is one of :
|
||||||
|
Integer, OctetString, OID, IpAddress, Counter32, Gauge, TimeTicks, Counter64.
|
||||||
|
.It Cm value
|
||||||
|
The value to be set - IP address in form of u.u.u.u - for example
|
||||||
|
1.3.1.6.1.2.0=IpAddress:192.168.0.1, strings require inverted-commas if they
|
||||||
|
contain any special characters or spaces, all other numeric types don't.
