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
