Libsmi is a C library that allows network management applications and MIB and PIB authoring tools to access SMI MIB module information and SPPI PIB module information through a well defined API that hides the nasty details of locating and parsing MIB or PIB modules. Libsmi supports exact and iterative retrieval functions for all major SMIv1/v2 and SPPI constructs.
There are four tools on top of the library and a sh/awk-script:
- Smiquery allows simple queries for single MIB/PIB module items.
- Smilint allows to increase the verbosity of the parser(s), so that module files can be checked for syntax and semantic errors.
- Smidump can be used to dump MIB and PIBmodules in various formats. The current output backends allow to dump trees of OIDs, type definitions and recursive imports, to convert modules between SMIv1 and SMIv2, to dump SPPI PIBs, to produce JIDM compliant CORBA-IDL files, UCD-SNMP code stubs, MOSY style output, JAX Java AgentX sub-agent templates, XML and XML-Schema MIB representations, Perl and Python representations, graphical conceptual models, and SCLI code stubs.
- Smidiff allows MIB authors, MIB reviewers and implementors to compare two revisions of the same MIB for legal and illegal changes.
- Finally, smistrip allows to strip SMIv1/v2 and SPPI modules from documents like RFCs and Internet-Drafts.
Enclosed with the libsmi package, there are all (bug fixed) current IETF standard MIB modules as of 2002-06-21, as well as some other modules, some SPPI PIBs that are taken from Internet Drafts, man pages for all library functions and tools, and a small libsmi test suite.
The software comes with automake/autoconf and libtool support. Hence it should compile and build with or without shared libraries on most UNIX style platforms, as well as on W32/cygwin, though it's just developed on Sun Solaris 2.5.x and Linux. However, questions about all platforms can be discussed on the libsmi mailinglist.
For those familiar with recent libsmi development: The most significant changes since the previous 0.3.x releases is the addition of the SPPI parser (which is integrated into the SMI parser), the addition of an SPPI dump driver (both supplied by Moritz Bunkus), and major enhancements of the XML Schema dump driver (supplied by Torsten Klie). Furthermore, a number of bugs have been fixed and many Standard MIB modules and PIB modules have been updated and added.
Online information on libsmi together with download and CVS access information, the (free) license terms, manual pages, and the mailing list is available at:
