SNMP4J 1.9.1c, SNMP4J-Agent 1.2 beta, and MIB Explorer 2.2.1
have been released and can be downloaded from
http://www.snmp4j.org and http://www.mibexplorer.com
respectively.
SNMP4J 1.9.1c contains a couple of bug fixes and now allows
to specify OIDs with ASCII strings (see change log for details).
SNMP4J-Agent 1.2 beta adds Property IO support to allow agent
configuration by a property file (see PropertyIOInput) and
the AgentConfigManager replaces the BaseAgent concept with
better usage of the inversion of control pattern.
The 1.2 version also fixes USM user serialization to retain
user configuration across agent shutdown.
AgenPro 2.7 adds support for using REFERENCE clauses for
SNMP4J-Agent to simplify generic instrumentations. In addition,
a Modules.java class is generated by the SNMP4J-Agent 1.2
templates that initializes/registers the generated MIB modules.
MIB Explorer 2.2.1 adds 3DES privacy, (auto-)filter support
for table view, support for SNMP4J snapshot files, and XML
support for monitor configuration and data.
RELEASE NOTES
=============
CHANGES SNMP4J v1.9.1c SINCE v1.8.2:
* Fixed: Missing PDUv1.clone() which could lead to wrong
SNMPv1 trap PDU encoding.
* Fixed: Possible deadlock race condition when processing
sync requests with retry > 0.
* Improved: Pending async requests will be removed after
timeout even if the response listener did not call
Snmp.cancel.
* Fixed: TableUtils did not return all rows if request
PDUs had to be splitted because of too much columns.
* Fixed: Transport not copied in Snmp.PendingRequest
which could cause wrong transport usage when processing
retries.
* Fixed: Async request processing for broadcasts (regression
bug in 1.9.1 which prevented mutliple responses for a
single async request).
* Improved: OID parsing from string now supports embedded
string to OID conversion, for example the following OIDs
are equal:
a = new OID("1.3.6.2.1.5.'hal.'.'''.'lo'.1");
b = new OID("1.3.6.2.1.5.104.97.108.46.39.108.111.1");
* Improved: Added factory pattern for creating PDU for
incoming messages parsed by message processing models.
* Fixed: Null LogLevel returned by JavaLogAdapter.getLogLevel.
* Fixed: With async request processing and retry>0 there
could have been a race condition where a response event
had been generated twice for a request.
* Fixed: ArgumentParser option multi parameter support
which failed to parse options like "-option param1 param2"
correctly.
* Changed: MessageDispatcherImpl can now be used to register
more than one transport mapping per address class (UDP/TCP).
Nevertheless, only the first registered one will be used
for sending SNMP messages if no specific transport mapping
is given.
* Improved: Target is cloned when used internally by Snmp
instance to avoid errors through concurrent target usage.
* Improved: PDU.add(VariableBinding) no longer clones
VariableBindings while adding it if the contained variable
is dynamic. Instead VariableBinding.setVariable clones
the set variable always as well the oid set by setOid(OID).
* Improved: Added factories for thread and timer instances
configurable through SNMP4JSettings class.
* Improved: Created interfaces for ThreadPool (WorkerPool)
and thread of execution (WorkerTask) as well as Timer
(CommonTimer) for better Java EE intergration.
* Added: ArgumentParser for simple command line parsing.
* Fixed: Local engine ID could not be set for simple PDU
request for the command line tool.
* Fixed: Walk modus of console example.
* Added: -Ocs and -Ods to create and dump subtree
snapshot files.
* Fixed: LogFactory.getLogFactory() returned null if
log factory has not been initialized yet. Now
a new instance of LogFactory is returned instead.
* Fixed: Typo in Snmp JavaDoc (getPdu() -> getPDU()).
* Added: Hook-up method in DefaultTCPTransportMapping
to allow setting socket options by extending the
class and overwriting the setSocketOptions method.
* Added: TripleDES-EDE privacy protocol implementation.
* Changed: SecurityProtocol interface to allow dynamic
key extension.
* Fixed: Race condition in DefaultTCPTransportMapping.
SNMP4J-Agent 1.2 since SNMP4J-Agent 1.1.4:
* Fixed: Direct usage of table model for row creation and
removal has been replaced by calling the corresponding
table methods for better object orientation.
* Fixed: MOScalar did return noSuchObject on a GET request
on the scalar without instance identifier instead
noSuchInstance.
* Added: UpdateStrategy and UpdatableManagedObject have
been added to allow centralized controlled updating
of dynamic managed objects (like DefaultMOTable)
* Improved: Design of org.snmp4j.agent.io components.
* Added: AgentConfigManager for IoC agent configuration
which replaces BaseAgent. The latter is deprecated now.
* Changed: MOServer interface.
* Added: BITS support for Enumerated[Scalar] classes.
* Added: USM user table persistency support.
* Changed: Made MOScalar.getAccess() public.
* Improved: TextAndIncr event generation.
* Changed: Access to public for MOScalar.getAccess()
* Added: Session update for AgentConfigurator.
AgenPro 2.7 since AgenPro 2.6.2a:
- Improved: Additional command line options to generate
code without repository and custom config file in batch
mode.
- Improved: SNMP4J-Agent 1.2 templates that generate also
the glue code to integrate the generated code into an
agent.
- Fixed: "x" can now be used as DESCRIPTION text.
- Added: Checks for consistent DISPLAY-HINT usage
in conjunction with TC SYNTAX.
- Fixed: COMPLIANCE-MODULE checks regarding imported
object groups and objects when used within current
module compliance definitions.
- Changed: Relaxed OBJECT IDENTIFIER assignment checks
to allow such assignments below object registrations.
- Fixed: Possible corruption of the MIB repository by
duplicate module IDs.
- Improved: MIB sorting for module compilation in
command line mode.
- Added: SNMP4J-Agent code generation property "package"
to generate code for a specific Java package.
- Added: SNMP4J-Agent code generation properties
"useReference" and "reference" to use/override the
content of a MIB objects REFERENCE clause in code
generation to support the generation of generic
instrumentation mappings.
- Added: SNMP4J-Agent 1.2 templates and project generate
a Modules.java file to easily integrate generated MIB
modules into an agent.
- Improved: MIB repository verification and auto repair
when a new MIB repository is selected.
MIB Explorer 2.2.1 since 2.1.3a:
* Fixed: "x" can now be used as DESCRIPTION text.
* Added: Checks for consistent DISPLAY-HINT usage
in conjunction with TC SYNTAX.
* Fixed: COMPLIANCE-MODULE checks regarding imported
object groups and objects when used within current
module compliance definitions.
* Changed: Relaxed OBJECT IDENTIFIER assignment checks
to allow such assignments below object registrations.
* Fixed: Possible corruption of the MIB repository by
duplicate module IDs.
* Improved: MIB repository verification and auto repair
when a new MIB repository is selected.
* Updated: IETF MIB modules.
* Fixed: Packets BER tree displayed an error around the
enterprise OID of SNMPv1 trap PDUs although the PDU
was correct.
* Fixed: Table and grid panel did not return all rows
on sparse tables when requests had to be splitted
because of too much columns.
* Added: Reading of SNMP4J snapshot files (which contain
no MIB information in contrast to MIB Explorer Pro
snapshot files).
* Added: Open and Save monitor files (including data) to
XML.
* Added: Backup history files for the monitor auto save
function. Now up to 99 (rolled) backup files can be saved
automatically while a monitor is running.
* Added: Experimental 3DES privacy support.
* Added: 3DES and AES key privacy change support.
* Added: Auto-filter (filtering by values of a table column)
and filtering by regular expressions for table view.
* Improved: Index values for enumeration are displayed
now with label information.
* Improved: Grid does not commit any unset (null) values
to the agent.
* Fixed: Non-editable fields in user configuration in
dependency of table sorting.
* Fixed: Editing of values could fail with "wrongType" error
for instances without MIB information.
* Improved: Application start and response time when DNS
service is not available or slow.
* Fixed: Table context menu was sometimes enabled even if
there was nothing to display as table.
* Improved: Table retrieval and update for sparse tables.
* Improved: MIB tree is updated to reflect available MIB
modules in new MIB repository when MIB repository is
changed. Before the MIB repository change is performed
where currently loaded MIB modules are not available,
the user is informed and may cancel the operation.
* Fixed: AES192 privacy protocol selection/name in user
configuration.
