The SNMP Name Resolver Plugin
A free plugin
to aid with SNMP analysis.
Description
This plugin is an addon module to Unsniff which allows you to
perform OID-Name resolution in
SNMP. This plugin features:
- A powerful MIB compiler (can compile both SMIv1 and SMIv2
MIBs)
- A fast database fine-tuned for read access
- A tool to quickly type in an OID and get its equivalent
“best-match� name
- A configuration utility
Installing
Prerequisites
: The Unsniff Network Analyzer
must be installed prior to installing this plugin.
Step 1 : Download
the plugin from the Unleash Networks Download page
Step 2 : Save
it to a location on your hard drive.
Step 3 : Click on the installer to
complete the installation (you must
install in the same folder as the main
Unsniff application)
Using the SNMP Name Resolver Plugin
Upon successful installation, the SNMP Name Resolver plugin will add
the following user interface elements:
- A toolbar with two buttons to the main Unsniff toolbar
- Two menu items grouped under "
Tools->SNMP"
The two menu items and the toolbar buttons provide access to the same
functionality listed below
| MIB
Compiler |
Click
on this to open the MIB Compiler window. Here you can select your
private MIB files you wish to add to the MIB database. This plugin
ships with several standard MIBs. |
| OID Lookup Tool |
Click on this to open the
simple OID lookup tool. Here y ou can enter an OID and convert it into
an object name. |
Resolving OIDs to names
Step 1: Enable
name resolution
- Select
Plugins->Configure
from the Unsniff main menu
- Locate the SNMP item and
enable the name resolution as shown
below.
Step
2: Compiling your private MIB files
- Place your private MIB files in a directory
- Select Tools->SNMP->Add Mibs from the main
Unsniff menu
- Click on the “Add MIB� button
on the
bottom left of the dialog
- Select the mib files you wish to compile and add
- The MIBs will be compiled and any errors will be sent to
the
Log Window (tab titled ‘1' )
- If you need to specify additional search directories to
locate
imported MIB definitions, Click on
the “New� button next to the “Search
Path� window
Now the SNMP plugin will convert any OID encountered to a name
using the plugin using any of
the three formats you selected. (Full name, Last Only, Last Few). The
plugin uses a best match
algorithm to locate names, so you can easily see table indexes as part
of the names.
Using the OID lookup tool
This tool allows you to query the database for an OID. To use
this tool:
- Select
Tools->SNMP->Lookup OID from the main
Unsniff menu
- Enter an OID and press lookup
