SNMP query of Windows2000 secret weapon

I. Brief introduction of the function

SNMP is the abbreviation of "Simple Network Management Protocol", the meaning of the Chinese language is "Easy Network Management Protocol", the role and details of this agreement, you can refer to the relevant information. This only describes the tool software Snmputilg.exe for the status query for this protocol. Also available in the Support Tools directory. As for the purpose, it is to provide the system administrator with information on SNMP to facilitate the troubleshooting when the reference. After you open the tool display interface, you can use it to perform operations such as GET, get-next, etc., or to make related settings. In addition, the tool can save data to the Clipboard or save the data as a text file with a comma-terminated symbol. In use, it should be noted that even though most objects use the default ID identifier (numeric value), you should use the SNMP SET command sparingly, since improper use of this command can lead to problems with Network name resources or connectivity problems.

Ii. Methods of Use

1. Startup program: In the Windows2000 environment, click "Start-> Run", type Snmputilg in the edit box and then enter or click "OK".

2. Unlike previously encountered, Snmputilg.exe is a graphical interface tool, although the execution of the program can use the Command Line Control window to open it, but the actual launch after the success of the interface is still graphics, open the interface as shown:

3. When the tool is started, the node edit box displays the default loopback address, and the address value is 127.0.0.1;current oid, which refers to the current object identifier, which is the number used to represent an object in the Windows system, and each identity is unique across the system, i.e. The identity does not, and does not allow, duplication.　The value shown in the figure is. 1.3.6.1.2.1. Public is the default choice for community. The items described above can also be selected for a different value.

4. If you select an IP address for another system, you must run the SNMP service, and the target system must have a network-accessible address configured, including address settings and permission opening. At the same time, the required assistive tools should also be available or operational. By default, Windows2000 is allowed access to all other system's IP addresses.

5. Another problem is community, when selecting the value of the community, one should be aware that the object it represents must exist, and the second note that its "readable" attribute can only be read after it has been granted permission. Third, note that this project may have different restrictions on access addresses in various versions of the Windows family.

6. The functions that SNMP can perform (SNMP function to execute) are listed in the Drop-down combo box in the figure and are available for selection. When selected, click the Execute command button to perform the corresponding action.

Here's a brief introduction to the features of these operations:

Get the value of the current object identifier: Gets the ID number

Get the "next value" after the current object identifier (this is the default): Gets the ID number of the next object immediately after it (which is the defaults)

Get the NEXT value after the current object identifier: The ID number of the 20 objects after the

Get all values from Object identifier down (WALK the tree): Gets the ID value of all objects from the current object

WALK the tree from WINS values down: Roaming directories from WINS value

WALK the tree from DHCP value down: Roaming directories from DHCP values

WALK the Lanman values down: roaming directories from Lanman values

WALK the Mib-ii Down (Internet MIB): Roaming directories from Mib-ii

7. Display the result meaning explanation:

These results can be purged or saved or updated, and to do this, you can use the corresponding actions in the menu, specifically, these actions include:

Copies one or more results into the clipboard.

Deletes all of the content that is now listed.

Clears all commands that have been executed.

Requests that the item currently selected be logged.

Produces a text file that holds the image of all the records with that file

Edit or set the identity of an object. Be cautious when using this action, because if you do this incorrectly, you may have problems with Network name resources or connectivity problems.

By the end of this article, diagnostic tools have been introduced, and the next one will be a simple comprehensive review and a preview of the tools to be introduced later.
