|
|
*5.8*
|
|
snmplib:
|
|
- TLS/DTLS fixes
|
|
- fix usm keychanges for new algorithms and longer keylengths
|
|
- IP address formatting fixes
|
|
- BUG: 2592: from Stuart Kendrick - increase MAXTC to 16384
|
|
- add new sha2 auth protocols
|
|
- Restore AES-192 and AES-256 privacy protocols - from
|
|
draft-blumenthal-aes-usm-04 (precursor to RFC 3826)
|
|
- Use OIDs from http://www.snmp.com/eso/esoConsortiumMIB.txt
|
|
- Some code borrowed from PATCH 1346, thanks to
|
|
Alexander Ivanov and Vladimir Sukhorukov.
|
|
- BUG: 2622: Fix excessive indents in log file
|
|
- new config tokens:
|
|
- sendMessageMaxSize
|
|
- disableSNMPv1 / disableSNMPv2c
|
|
- new api for dynamic debug log level (netsnmp_set_debug_log_level)
|
|
|
|
snmpd:
|
|
- SNMP-TARGET-MIB: Fix snmpTargetAddrTAddress
|
|
- Com2sec and com2sec6 SOURCE values may deny sources as well as
|
|
permit.
|
|
- allow trap sinks to set Target-MIB characteristics (name, tag, profile)
|
|
- add source addr/port option to trapsink/trap2sink/informsink
|
|
- packet filtering by source ip (enableSourceFiltering/filtersource)
|
|
- several getbulk handling improvements
|
|
- several new APIs introduced for run-time configuration of agent:
|
|
- netsnmp_vacm_simple_usm_add/del
|
|
- usm_create_usmUser_*
|
|
- netsnmp_udp_com2SecEntry_create/netsnmp_udp_com2SecList_remove
|
|
- netsnmp_agent_listen_on to open agent port
|
|
|
|
Win32:
|
|
- Add support for the DTLS-UDP and TLS-TCP transports
|
|
|
|
scripts:
|
|
- A new 'checkbandwidth' script to check host min/max bandwidth
|
|
|
|
snmptranslate:
|
|
- Introduce bulk translation mode The special argument "-" causes
|
|
snmptranslate to enter bulk translation mode, in which it expects
|
|
one OID per line. Whitespace is treated as the end of the OID, and
|
|
only that portion of the line is replaced, meaning that this can be
|
|
used to translate, e.g., "snmpwalk" output without the proper MIBs
|
|
loaded: snmptranslate -m all -OX < numeric.txt > symbolic.txt
|
|
|
|
building:
|
|
- Add Travis and Appveyor CI support
|
|
- IPv6 support is now compiled by default. If you need an IPv4-only
|
|
agent, use --disable-ipv6.
|
|
- Fixed/improved support for several non-Linux platforms
|
|
- Many fixes found by Coverity anf Fortify scans
|
|
|
|
*5.7.3*
|
|
Many many bug fixes and minor improvements
|
|
|
|
snmpd, snmptrapd and apps:
|
|
- Patch 2525: from Ryan Steinmetz: Fix argument length parsing of the
|
|
host resources mib
|
|
- Make ENV_SEPARATOR_CHAR configurable
|
|
- SECURITY: a denial of service attack vector was discovered on
|
|
the linux implementation of the ICMP-MIB. This release fixes
|
|
this bug and all users are encouraged to update their SNMP
|
|
agent if they make use of the ICMP-MIB table objects.
|
|
|
|
perl:
|
|
- BUG: 2402: Add support for SNMPv3 traps
|
|
|
|
Windows:
|
|
- Port batch build infrastructure to Visual Studio 2010 and later
|
|
From Visual Studio 2010 on it is no longer possible to specify
|
|
include or library directories globally - these have to be
|
|
specified per project. Hence two additional menu entries in
|
|
build.bat that allow to specify these directories.
|
|
- Patch from Bart Van Assche to improve cygwin building
|
|
|
|
*5.7.2*

|
|
|
|
building:
|
|
- PATCH: 2091156: correctly declare dependencies in Makefile. 'make
|
|
-j <N>' should work now. Backport this to V5-4 as it is needed for
|
|
correct operation in the single threaded case of make miblib as
|
|
well.

|
- New transport functions: f_config, f_open, f_copy and f_setup_session
|
|
- Transports can now specify session defaults
|
|
- E.G. dtlsudp: auto-sets the SNMP version and the security model.
|
|
- [PATCH 2942940]: Add a new function, netsnmp_parse_args, that is

affect the behaviour. Also remove the magic handling of some
|
|
application names.
|
|
- A new X.509 certificate API for indexing and reading certificates
|
|

*5.4*
|
|
|
|
Important Changes:
|
|
- The default configuration now enables embedded Perl and the Perl
|
|
modules by default when possible unless explicitly disabled. You
|
|
may use the --disable-embedded-perl and --without-perl-modules
|
|
configure options, respectively, to revert to the former default
|
|
configuration.
|
|
|
|
New:
|
|
python:
|
|
- Python bindings to the Net-SNMP project are now available in
|
|
the python sub-directory. See the README file there for details.
|
|
|
|
build:
|
|
- Some preliminary support for automatic building of dynamically
|
|
loadable mib module code.
|
|
- Most net-snmp specific defines are now (also) available under
|
|
a proper NETSNMP_ prefix. The older, potentially conflicting
|
|
names as well as the autoconf variables can now be turned off
|
|
easily within 3rd party code.
|
|
- libtool update to 1.5.22
|
|
- enable-as-needed will try to link built libraries against needed
|
|
libraries at library link time, rather than application link time.
|
|
This is preliminary support for what will likely be better in 5.5.
|
|
|
|
snmplib:
|
|
- [PATCH 1282566]: to rework transport creation to allow for
|
|
alternative interpretations of the address and a more flexible
|
|
transport registration system
|
|
- [PATCH 1509943]: responses will get sent from the original dest IP
|
|
address when possible.
|
|
|
|
snmpd:
|
|
- new MIB table for managing Net-SNMP access control extensions
|
|
(see NET-SNMP-VACM-MIB). These extensions to the VACM MIB are
|
|
Net-SNMP specific and are used primarily by snmptrapd at this point.
|
|
- [PATCH 1550725]: A new uint instance helper to match the existing
|
|
int, long and ulong helpers
|
|
- [PATCH 1534877]: to add support for skipping NFS entries in the
|
|
host resources hrStorageTable. See the skipNFSInHostResources
|
|
token in the snmpd.conf file for details.
|
|
- A "hardware abstraction layer", to localise the O/S-specific
|
|
aspects of retrieving system data. This first appeared in the
|
|
5.3.x line, but this release now starts to actively use it for
|
|
implementing particular MIB modules.
|
|
This has resulted in some minor changes in behaviour - some index
|
|
values in the hrStorageTable have changed from earlier releases,
|
|
and the (non-raw) memory statistics are now consistent, reporting
|
|
percentage usage calculated over the last minute on _all_ systems.
|
|
- Agent builds default module list from a default_mibs.h rather than
|
|
a hard coded configure list
|
|
- [PATCH 1568150]: Extend pass_persist error messages that can be
|
|
passed back from the script
|
|
- [PATCH 1570982]: Solaris IF-MIB: Support for IPv6-only interfaces
|
|
|
|
snmptrapd:
|
|
- the traphandle directive now supports a -t switch to indicate
|
|
matching any OID in the tree below the specified OID
|
|
|
|
mib2c:
|
|
- New mib2c.emulation.conf provides a quick way to do simplistic
|
|
emulation of an entire MIB or MIB branch.
|
|
- A new perl module NetSNMP::agent::Support provides easier embedded
|
|
perl support. (patch 1369996 from Peter Martin)

*5.3.0.1*
|
|
|
|
*** Security Fix ***
|
|
|
|
- In version 5.3 much of the authorization control was rewritten.
|
|
There was a bug in the new code that resulted in granting write
|
|
access to read-only users or communities which were configured
|
|
using the "rocommunity" or "rouser" snmpd.conf tokens. 5.3.0.1
|
|
fixes this problem. Users are encouraged to immediately update
|
|
their installations if they use either of these tokens.
|
|
|
|
|
|
*5.3*
|
|
|
|
*** Important Notes ***
|
|
|
|
Several very significant changes have been made in Net-SNMP for this
|
|
release that warrant special attention.
|
|
|
|
- shared library version number no longer matches the release number. We
|
|
now follow the versioning scheme recommended by libtool. For the 5.3
|
|
release this means that the libraries now have a SONAME ending with
|
|
".so.10", e.g. libnetsnmp.so.10.
|
|
|
|
- snmpd has not been truncating log files at startup, as documented in
|
|
the man pages, for a while now. This default behaviour has been restored.
|
|
Please use the '-A' flag if you want to continue appending to your log
|
|
files at startup.
|
|
|
|
- snmptrapd will no longer accept all traps by default. It must be
|
|
configured with authorized SNMPv1/v2c community strings and/or SNMPv3
|
|
users. Non-authorized traps/informs will be dropped.
|
|
|
|
- Due to a copyright statement that didn't allow modifications,
|
|
snmpnetstat has been completely rewritten. The new version now
|
|
accepts the same command-line options as the other tools, which
|
|
has introduced a number of incompatible changes. However, it
|
|
does now finally support SNMPv3.
|
|
|
|
New:
|
|
Building:
|
|
- new option to disable set support in the agent (--disable-set-support)
|
|
|
|
snmpd:
|
|
- implement notification logging
|
|
- implement notification filtering
|
|
- AgentX, host resources and disman/event mibs added to default module list
|
|
- updated and new disman mib implementations
|
|
|
|
snmptrapd:
|
|
- allow a non-default AgentX socket
|
|
- a brand new authorization scheme that is based on the VACM
|
|
authorization scheme from snmpd.
|
|
- Note: now drops unauthenticated notifications by default
|
|
- registers the snmpEngine MIB group under the "snmptrapd" context
|
|
|
|
snmplib:
|
|
- new helper for ascii file based scalar integers (think Linux /proc/)
|
|
- new utilities for dealing with files
|
|
- new utilities for parsing text files
|
|
- granular config/persistent file disablement (noPersistentLoad and
|
|
noPersistentSave snmp.conf tokens)
|
|
|
|
mib2c:
|
|
- mib2c.mfd.conf now generates code for persistence row storage
|
|
- many enhancements and bug fixes
|
|
|
|
snmpusm:
|
|
- allows to use old and/or new localized key instead of passphrase with
|
|
option -Ck
|
|
- new option -CE to specify usmUserEngineID (necessary to manage
|
|
snmptrapd's usmUserTable)
|
|
|
|
Ports:
|
|
Linux:
|
|
- new experimental tables
|
|
- tcpConnectionTable, tcpListenerTable
|
|
- ipAddressPrefixTable
|
|
- udpEndpointTable
|
|
- ipv4InterfaceTable, ipv6InterfaceTable
|
|
- inetCidrRouteTable supports dynamic ipv4 route creation/deletion
|
|
- added ipv6IpForwarding.0 and ipv6IpDefaultHopLimit.0 (read-write)
|
|
|
|
Win32:
|
|
- Cygwin compiler fixes
|
|
- MSVC: agent (snmpd) support for pass and pass_persist
|
|
- MinGW: agent (snmpd) support for pass
|
|
- Fix for 'select: No such file or directory' in snmpdelta
|
|
|
|
Fixes:
|
|
- Persistent files in directory defined by snmp.conf persistentDir were
|
|
not being loaded at startup
|
|
- Perl getnext didn't honor explicit reference to MIB file
|
|
- AgentX sub-agent connection delayed til after config files read
|
|
- Build fixes for --disable-agent, --disable-snmpv1 and --disable-snmpv2c
|
|
- Lots of bug fixes
|
|
|
|
|
|
*5.2*
|
|
New:
|
|
For the security paranoid (like Wes):
|
|
- Insecure versions of SNMP may be completely disabled at compile time.
|
|
(configure using one or both of --disable-snmpv1 --disable-snmpv2c)
|
|
- Less secure versions of SNMPv3 authentication and encryption
|
|
algorithms may be completely disabled at compile time.
|
|
(configure using one or both of --disable-des --disable-md5)
|
|
(This requires you have OpenSSL to support SHA1 and AES instead)
|
|
- Diffie-Helman key negotiation (perfect-forward-secrecy - RFC2786)
|
|
has been implemented in both the agent and "snmpusm".
|
|
- Better support for direct use of localized and master keys
|
|
(randomly generated keys have more entropy than passwords). See
|
|
the -3m -3M -3k and -3K options, and the defAuthLocalizedKey,
|
|
defPrivLocalizedKey, defAuthMasterKey, defPrivMasterKey
|
|
snmp.conf tokens)
|
|
|
|
library:
|
|
- send and receive buffer sizes for UDP/TCP are configurable
|
|
- .conf file token registration can now search multiple files
|
|
(separate file names to search by a :. IE, "snmpd:agentx")
|
|
|
|
snmptrapd:
|
|
- Embedded perl support for trap handlers (much faster than traphandles).
|
|
(configure --with-embedded-perl ; see 'perldoc NetSNMP::TrapReceiver')
|
|
- the snmptrapd usmUser table can be controlled through SNMP & AgentX
|
|
(the snmptrapd registers MIBs under the "snmptrapd" SNMPv3 context)
|
|
|
|
agent:
|
|
- community strings can be mapped to individual SNMPv3 contexts
|
|
(see the snmpd.conf manual on "com2sec").
|
|
- AgentX should work properly with SNMPv3 contexts now.
|
|
- improved version of "exec" extension directive - "extend":
|
|
supports multi-line output, configurable command input, SET
|
|
handling, a valid relocatable MIB output structure, etc
|
|
- more flexibility added to netsnmp_cache helper, including periodic
|
|
refreshing of caches and cache pre-loading.
|
|
- experimental implementation of DisMan Remote Operations MIB groups
|
|
(remote nslookup, ping, traceroute and expressions via SNMP)
|
|
- The proxy supports a new -Cc flag which passes the community
|
|
name through to the other side rather than hard-coding it.
|
|
- The config_require() and other modules can now be placed
|
|
inside of CPP directievs (#if, /* ... */) as header files are
|
|
now passed through CPP processing first.
|
|
- new config_exclude() macro for excluding certain modules
|
|
- new config_belongs_in() macro to specify if a chunk of code
|
|
found by --with-mib-modules belongs in the agent library or
|
|
the mib module library.
|
|
- Uses a smaller function stack.
|
|
|
|
commands:
|
|
- snmpusm: A number of key-change improvements
|
|
(EG, changing localized keys supported, diffie-helman support, ...)
|
|
- New -Ln option to completely disable logging.
|
|
|
|
mib2c:
|
|
- a number of new or updated configuration templates:
|
|
- mib2c.iterate.conf: the iterator-based table config
|
|
now produces fuller template code than before.
|
|
- mib2c.table_data.conf and mib2c.container.conf:
|
|
two new "internal-row" style configs
|
|
- mib2c.mfd.conf: "MIBs for Dummies" (or MFD) - intended to
|
|
reduce the SNMP knowledge needed to develop MIB modules
|
|
and add flexibility at the same time. Run "mib2c -S
|
|
mfd_interactive_setup=1 -c mib2c.mfd.conf OID" and follow
|
|
its guided instructions to help you tailor its results to
|
|
meet your needs.
|
|
- mib2c.genhtml.conf: Generates an easier-to-read HTML view of
|
|
a MIB tree structure. (See http://www.Net-SNMP.org/mibs/
|
|
for example output.)
|
|
- more node tags available for conf file writers
|
|
- additional search directories may be set via MIB2C_DIRS env var.
|
|
- mib2c-update: new utility to help update mib2c generated code
|
|
when conf file changes.
|
|
- a mib2c.conf manual page to describe how to write mib2c .conf files.
|
|
- support for embedded perl code in mib2c.conf files
|
|
|
|
documentation:
|
|
- New README.agent-mibs: an attempt to start documenting what
|
|
MIBs are implemented in the agent and on what architectures.
|
|
|
|
perl:
|
|
- An improved SNMP::gettable() method. Uses GETBULK if possible and
|
|
better GETNEXT requests if not, decodes indexes from OIDs,
|
|
requests multiple variables at once, ... ("perldoc SNMP" for details)
|
|
- A NetSNMP::OID::get_indexes() function to extract index values
|
|
from an OID.
|
|
|
|
Ports:
|
|
Linux:
|
|
- new experimental tables/rewrites for Linux, including:
|
|
ifTable, ifXTable, inetCidrRouteTable, ipCidrRouteTable,
|
|
ipAddressTable, ipSystemStatsTable, ipNetToPhysicalTable.
|
|
- Enable these talbles by specifying --enable-mfd-rewrites to configure.
|
|
- Most of these tables have IPv6 support as well.
|
|
- ifIndex no longer changes when interfaces are added/removed, and all
|
|
tables/object will now use the same ifIndex for the same interface.
|
|

*5.0.4*
|
|
|
|
During the testing for release 5.0.4, a release candidate was uploaded
|
|
to Sourceforge and marked as hidden. For various reasons, the release
|
|
was delayed and further changes and fixes were made. However, the
|
|
release candidate files still appeared on the public FTP server and our
|
|
mirrors. To avoid the confusion that could occur to users who may have
|
|

|
*5.0*
|
|
|
|
New:
|
|
|
|
- Much of the agent internals were completely rewritten and sports
|
|
a new module API to make your life easier. See the
|
|
agent/mibgroup/examples directory for example code that makes
|
|
use of some of the new functionality.
|
|
(Also see http://www.net-snmp.org/tutorial-5/agent/ which has
|
|
some incomplete documentation)
|
|
- The agent sports embedded perl, see the perl details further below.
|
|
- The agent supports multiple SNMPv3 contexts and mib modules can
|
|
now register themselves under different contexts. (see the -n
|
|
option in the snmpcmd manual page for details on specifying
|
|
context strings in requests)
|
|
- The proxy code has been completely rewritten and now supports
|
|
the use of SNMPv3 contexts to help select which proxied host you
|
|
wish to talk to. See the snmpd.conf manual page.
|
|
- All the tools take --configToken=value options now. (see -H
|
|
output from any command for what configTokens it accepts)
|
|
- All the tools can speak over many different transport layers
|
|
now, including UDP/TCP (ipv4 and ipv6), AAL5pvc, and IPX. See
|
|
./configure --help for details on enabling them.
|
|
Note: the -p and -T flags to all the applications have been
|
|
removed. Use hostname strings like "tcp:localhost:9999"
|
|
instead. See the snmpcmd manual page for details.
|
|
- snmptrapd now acts as an agentx subagent and implements portions
|
|
of the NOTIFICATION-LOG-MIB to allow captured traps and informs
|
|
to be queried.
|
|
- A "net-snmp-config" script will get installed which can report
|
|
how the various tools were built (which libraries they were
|
|
linked against, etc). It will also help you do other things as
|
|
well, like setting up snmpv3. Run net-snmp-config --help for details.
|
|
- kerberos authenticated and encrypted SNMPv3 is now possible.
|
|
See ./configure --help for details on enabling the ksm security module.
|
|
- The AgentX subagent protocol implementation has many new
|
|
features and fixes.
|
|
- mib2c was completely rewritten and has a much improved
|
|
configuration file specification.
|
|
- Much of the code is getting documented with "doxygen" style
|
|
documentation. Run "make docs" if you have doxygen installed.
|
|
- some RMON support is available.
|
|
(See agent/mibgroup/Rmon/README for details.)
|
|
- The source tree has been reorganized and all the exported header
|
|
files are now in the include subdirectory. You can now point to
|
|
the includes easily without having to run "make install" first.
|
|
- the agent now requires a configuration file to access any information.
|
|
- The entire code base has had indent run on it to effect a
|
|
consistent coding style. See the CodingStyle file for details.
|
|
|
|
Perl:
|
|
|
|
- The SNMP perl module now calls init_snmp() like real net-snmp
|
|
applications, which means it will read snmp.conf configuration
|
|
files, etc.
|
|
- new perl specific configure options --with-perl-modules &
|
|
--enable-embedded-perl. See ./configure --help for details.
|
|
- The beginnings of some new Perl modules (alpha level quality)
|
|
are in the perl directory, including:
|
|
- NetSNMP::agent which allows perl scripts to become net-snmp
|
|
master or subagents
|
|
- AnyData::SNMP is available that implements a perl DBI
|
|
interface to map SQL commands to SNMP. Included is a "netsh"
|
|
shell where SQL commands can be typed, aliases created, etc.
|
|
See the perl/AnyData_SNMP/INSTALL file for details.
|
|
- Beginning (alpha level quality) support for embedding perl
|
|
subroutines directly within the net-snmp agent.
|
|

|
- many of the table oids have changed location and have been renamed.
|
|
- the View Based Access Control module was implemented in the agent.
|
|
Therefore, the "community" snmpd.conf parameter no longer
|
|
exists. See the snmpd.conf file for how to control access via
|
|
community names now.
|
|
- The header file #defines have changed. You may have to compile
|
|
third party applications with -DCMU_COMPATIBLE (like perl-SNMP <= V1.7).
|
|
- The parser is more strict about unlinked OIDs and end-of-comment
|
|
conditions. You may see problems in a few broken mibs that used
|
|
to parse ok with the older parser.
|
|
|
|
New:
|
|
- dynamic library support: configure with --enable-shared.
|
|
- the beginnings of a Perl/Tk/SNMP mib browser: tkmib

|
|
- default mib list changes when you add or remove agent mib-groups.
|
|
- debugging in the agent can be turned on and off using snmpsets.
|
|
- a new mib module displays a list of all loaded mib modules.

|
- the internal structure of the agent's mib modules is now hierarchical.
|
|
- the agent looks for .conf files in both the lib/ and share/ directories.
|
|
- more improvements/options to snmptable.
|
|
- new vmstat module to report vmstat related information under linux.
|
|
- a perl based mib2c translator to convert mib sections to C code templates.
|
|
|
|
Fixes:
|
|
- The code was run through purify for memory leaks and a few were found.
|
|
- snmptrap sends to the correct default port of 162 again.
|
|
|
|
Ports:
|
|
- irix 6.2 support improved.
|
|
- openbsd.
|
|
- the host resources mib compiles on Solaris.
|
|
|
|
*3.3.1*
|
|
|
|
New:
|
|

|
- host resources works a bit better (ie, it compiles) under solaris.
|
|
|
|
|
|
*3.3*
|
|
|
|

|
- the default paths to the installed mibs and snmpd.conf file have
|
|
changed to /usr/local/share/snmp (set differently using --datadir).
|
|
- the default path of the snmpd and snmptrapd have changed to
|
|
/usr/local/sbin (set differently using --sbindir).
|
|
|
|
New:
|
|
- basic SNMPV2c support.
|
|
- Not fully tested (feedback please!), and not RFC compliant.
|
|
- all apps require '-v 2c' for v2c and '-v 2p' for the older party code.
|
|
- basic host-resources mib support for linux, and hpux.
|
|
- All environment variables can be set with a preceding '+' for
|
|
indicating additions to the default values.
|
|
- mib modules cleaned up more and can be added and removed more easily.
|
|
- mib modules have a new macro for callbacks when reading a .conf file.
|
|
- apps command line interfaces have merged together for standardization.
|
|
- the libsnmp library no longer forces printing of errors.
|
|
- 2 new applications: snmpdelta and snmptable.
|
|
- the mib parser caches mib directory scans for speed improvements.
|
|
- snmptrapd is snmp-version multi-lingual.

|
|

|
|
- reads import clauses to load other required modules
|
|
- new man page: mib_api.3
|
|
- The agent has been completely restructured (modularized) to
|
|
allow for easier extension via C code and requires no
|
|
modification of the ucd-snmp distributed source code to add in
|
|
new C coded mib modules. See the README file in the
|
|
agent/mibgroup subdirectory for details. Modules are added and/or
|
|
removed via configure options.
|
|
- agent can send traps to multiple trap destinations.
|
|
- configure can be run outside the default source directory.
