- the ChangeLog file for a more detailed listing of changes/bug fixes.
- *5.2.2*
- New:
- - Due to a copyright statement that didn't allow modifications,
- snmpnetstat was completely rewritten. The new binary is named
- snmpnetstat53, and we've provided a snmpnetstat wrapper script to
- make the command line options backwards compatible. As a side
- effect, however, it now finally supports SNMPv3 at least.
- Ports:

- *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.

- from an OID.
- Ports:
- Linux:
- - new experimental tables/rewrites for Linux, including:

- - Enable these talbles by specifying --enable-mfd-rewrites to configure.

- *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.
