Net-SNMP 5.4 is now available

I'm happy to announce the release of version 5.4 of Net-SNMP.

  One important item about this release:

  - 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.

What has Changed recently?
-------------------------------------------

  The NEWS file snippits from these releases are as follows:

  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.

    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 1562688]: fix ping/reattach agentx code
      - [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

    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.

    snmpusm:
      - performance improvement when changing localized keys
      - new option -Cp to set usmUserPublic value

    snmpvacm:
      - new commands to manipulate Net-SNMP access control extensions

    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)
        Run "mib2c -c mib2c.perl.conf OID" to help you start using it.

    perl:
      - gettable() now supports asynchronous callback functions
      - update default_store module to latest default_store c-binding
	tokens
      - fixes for 64-bit platforms

 Ports:
   Linux:
      - add IPv6 aware UDP and TCP mibs to default module list

   Solaris, FreeBSD, OpenBSD:
      - Experimental support for 64bit interface counters (ifXTable). Enable
        via '--with-mib-modules=if-mib --enable-mfd-rewrites'.
      - [PATCH 1569537,1569539]: new UDP-MIB and TCP-MIB implementation
	(enable through --with-mib-modules=udp-mib,tcp-mib)

   Win32:
      - new winExtDLL extension module to allow snmpd to load Windows SNMP
        Service extension DLLs to provide support for HOST-RESOURCES-MIB
        and other MIBs provided with Windows.

   AIX:
      - HOST-RESOURCES-MIB implementation added to default module list

   uCLinux
      - [PATCH 1551948]: Make pass_persist usable on uClinux

  Fixes:
    snmpd:
      - fix disman/event monitoring crashes (official patch 1429059)
      - fix re-init of daemons after SIGHUP (official patch 1473289)
      - fix trap processing from SMUX peers (patch 1430824)

      - [BUG 1427410]: Set auth engineID for SNMPv3 traps.
      - [BUG 1535903]: Support spaces within security names
      - fix 8 byte IpAddress in at, ip and route MIBs.

    snmptrapd:

        (official patch 1420758)
      - fix re-init of daemons after SIGHUP (official patch 1473289)

    snmplib:
      - fix OID lookups for fully qualified object names (eg .iso.org)
        (official patch 1421725)
      - UDPIPv6 and TCPIPv6 transports now compile on recent UN*X platforms

    perl:
      - Fixed the perl bulkwalk function
      - gettable() was fairly broken in prior versions 
      - OID handling was fully broken on various 64bit platforms

    misc:
      - Many misc fixes


Where can I get it?
------------------

  Download:
    - http://www.net-snmp.org/download/
    - ftp://ftp.net-snmp.org/pub/sourceforge/net-snmp/
  Web page:
    - http://www.net-snmp.org/
  Sourceforge Project page:
    - http://www.net-snmp.org/project/
  Mirrors (note that sourceforge download servers are mirrored themselves):
    - US:          ftp://ftp.freesnmp.com/mirrors/net-snmp/
    - Greece:      ftp://ftp.ntua.gr/pub/net/snmp/net-snmp/

Are there binaries available?
----------------------------

  - Binaries do appear on our download site, but often are published a
    bit later than the normal source code.  Most of the binaries that
    are available have been linked with the OpenSSL package so you'll
    need a copy of it installed in order to use them.  If you don't
    have OpenSSL installed and don't want it installed, please get the
    net-snmp source release instead and built it yourself (but you'll
    loose support for SNMPv3 with SHA1 authentication and both DES and
    AES encryption).

What operating systems does it run on?
-------------------------------------

  Both the applications and the agent have been reported as running
  (at least in part) on the following operating systems:

        * Linux (kernels 2.6 to 1.3)
        * Solaris/SPARC (11 to 2.3), Solaris/Intel (10, 9) -- see 
          README.solaris

  portability of the Net-SNMP package.

Which versions of the SNMP protocol are supported in this package?
-----------------------------------------------------------------

  SNMPv1, SNMPv2c, and SNMPv3 (including user-based and kerberos-based support) 

I've found a bug or have a suggestion, how do I tell you about it?
-----------------------------------------------------------------

  Please submit the bug to our bug-tracking system at:

    http://www.net-snmp.org/bugs/

  Please submit patches (for features or bugs) to our patch-tracking
  system.  (You don't need to submit a big report as well, just a patch)

    http://www.net-snmp.org/patches/

What's the difference between UCD-SNMP and Net-SNMP?
---------------------------------------------------

  Not a great deal, really.
  Although the project originally started at UC Davis (hence the name),
  and it has always been based there, most of the contributors have had
  little or no connection with this institution.

    The move to SourceForge was intended to provide a more flexible
  environment for the project, and to distribute the administrative
  workload more evenly.  The change of name simply reflects this move,
  which was the last remaining link with UC Davis.

    The 4.2.x line is the last release line that uses the ucd-snmp name,
  and all releases under this banner will be bug-fixes only.  Release
  5.0 is the first version using the net-snmp name, and all new features
  and significant development will be released under this name.
    (Though the dividing line between a bug-fix and a new feature is
  something of a vague one, so some changes in the 4.2.x line may be
  relatively non-trivial!)
