NAME

       smilint - syntax and semantic checks of SMIv1/v2 and SPPI modules


SYNOPSIS

       smilint  [ -Vhersm ] [ -c file ] [ -p module ] [ -l level ] [ -i error-
       pattern ] module(s)


DESCRIPTION

       The smilint program is used to check MIB  or  PIB  modules  for  syntax
       errors  and  semantics  at  some degree.  SMIv1/v2 style MIB modules as
       well as SPPI PIB modules are supported.

       The rules that smilint is based on are taken from RFC  1155,  RFC  1212
       and RFC 1215 for SMIv1, RFCs 2578-2580 for SMIv2, RFC 3159 for SPPI.


OPTIONS

       -V, --version
              Show the smilint version and exit.

       -h, --help
              Show a help text and exit.

       -e, --error-list
              Show a list of all known error messages and exit. Error messages
              can have associated tags, shown in braces at  the  end  of  each
              line.  The tags can be used with the -i option to ignore certain
              error messages.

       -r, --recursive
              Report errors and warnings also for  recursively  imported  mod-
              ules.

       -s, --severity
              Show the error severity in brackets before error messages.

       -m, --error-names
              Show the error names in braces before error messages.

       -c file, --config=file
              Read  file  instead of any other (global and user) configuration
              file.

       -p module, --preload=module
              Preload the module module before  reading  the  main  module(s).
              This  may  be  helpful  if  an  incomplete main module misses to
              import some definitions.

       -l level, --level=level
              Report errors and warnings up to the given severity level.   See
              below  for  a description of the error levels. The default error
              level is 3.

       -i prefix, --ignore=prefix
              Ignore all errors that have a tag which matches prefix.  A  list
              of  error  tags  can be retrieved by calling smilint with the -e
              option.

       module(s)
              These are the modules to be checked. If a module argument repre-
              sents  a path name (identified by containing at least one dot or
              slash character), this is assumed to be the exact file to  read.
              Otherwise,  if  a module is identified by its plain module name,
              it is searched according to libsmi internal rules. See  smi_con-
              fig(3) for more details.


ERROR AND WARNING LEVELS

       All  generated  error  and warning messages have an associated severity
       level.  The actual severity levels are:

       0  Internal error, no recovery possible. Examples are memory allocation
          failures.  Errors  of  this  level  usually cause the application to
          abort.

       1  Major SMI/SPPI error, recovery somehow  possible  but  may  lead  to
          severe  problems.  Examples  are  lexically unexpected characters or
          unknown keywords. Errors of this  kind  usually  lead  to  follow-on
          errors.

       2  SMI/SPPI  error which is probably tolerated by some implementations.
          Examples are MIB/PIB modules which  mix  constructs  from  different
          SMI/SPPI versions.

       3  SMI/SPPI  error  which  is likely tolerated by many implementations.
          Examples are misplaced SMIv2 MODULE-IDENTITY  invocations  or  SMIv2
          textual conventions derived from other textual conventions.

       4  Something which is not strictly an error but which is recommended to
          be changed. Warnings of this level are usually considered during MIB
          reviews.

       5  Something that is basically correct but might be problematic in cer-
          tain environments or usage scenarios.  Examples  are  warnings  that
          identifiers  only  differ  in  case or that type definitions are not
          used within the defining module.

       6  Messages of this level are auxiliary notices. Examples are  messages
          that point to a previous definition in case of a redefinition.

       Higher  levels  are  currently not used and lead to the same effects as
       level 6 does. Note that errors up to level 3 are errors  violating  the
       specifications  and  must be fixed by the responsible author. The warn-
       ings generated with level 4 should be considered during normal  MIB/PIB
       reviews.


EXAMPLE

       This  example  checks the file RMON2-MIB in the current directory (note
       that the `./' prefix ensures this). The error level is raised to 6  and
       warnings  that  claim about identifier names that exceed a length of 32
       characters are suppressed.

         $ smilint -l 6 -i namelength-32 ./RMON2-MIB
         ./RMON2-MIB:3935: unexpected type restriction
         ./RMON2-MIB:3936: unexpected type restriction
         ./RMON2-MIB:3937: unexpected type restriction
         ./RMON2-MIB:3938: unexpected type restriction
         ./RMON2-MIB:3939: unexpected type restriction
         ./RMON2-MIB:3940: unexpected type restriction
         ./RMON2-MIB:4164: scalar object must not have a `read-create' access value
