Win2k "secret weapon" SNMP query

First, the role of the brief

SNMP is the abbreviation of "Simple Network Management Protocol", the Chinese meaning is "simple network management protocol", the role and details of this agreement, you can refer to the relevant information. Only the tool software Snmputilg.exe for status query for this protocol is introduced here. It is also provided in the Support Tools directory. As for the use, it is nothing more than to provide system administrators with information about SNMP, so that it can be used as a reference when troubleshooting. After opening the tool display interface, you can use it to perform operations such as GET, GET-NEXT, etc. or make related settings. In addition, this tool can also save data to the clipboard or save the data as a text file with a comma as the closing symbol. In use, it should be noted that even if most objects use the default ID (value), you should use the SNMP SET command with caution, because incorrect use of this command may cause problems with network name resources or Problems in causing connectivity.

Second, use

1. Start the program: In the windows2000 environment, click "Start -> Run", type snmputilg in the edit box and press Enter or click "OK".

2. Unlike the previous ones, Snmputilg.exe is a graphical interface tool. Although you can use the command line control window to open it when you execute the program, the interface that appears after the actual startup is still the graphics. The open interface is as shown in the figure:

3. After the tool is started, the default editback address is displayed in the Node edit box, the address value is 127.0.0.1; the Current OID refers to the "current object identifier". The logo is a number used to represent an object in the windows system. Each identifier is unique in the entire system, that is, the logo does not and does not allow duplicates. The values ​​shown in the figure are .1.3.6.1.2.1. Public is the default choice for the community item. The items described above can also be selected for other values.

4. If you choose another system's IP address, you must run the SNMP service, and the target system must be configured with the network access address, the so-called configuration, including address settings and permissions open. At the same time, the required auxiliary tools should also be available or operational. By default, Windows 2000 allows access to the IP addresses of all other systems.

5. Another problem is community. When the value of community is selected, one must note that the object it represents must exist. Second, note that its "readable" attribute can only be read after it is allowed. . Third, pay attention to this project in the different versions of the windows series, the access address restrictions may be different.

6. All 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. Once you have made your selection, click the Execute Command button to perform the corresponding action.

The following is a brief introduction to the functions of these operations:

GET the value of the current object identifier: get the ID value of the current object

GET the NEXT value after the current object Identifier (this is the default): Get the ID value of the next object immediately after the current object (this is the default)

GET the NEXT 20 values ​​after the current object identifier: after the current object ID value of 20 objects

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

WALK the tree from WINS Values ​​down: roaming directory from WINS value

WALK the tree from DHCP values ​​down: roaming directory from DHCP value

WALK the tree from LANMAN values ​​down: down from LANMAN value Roaming directory

WALK the tree from MIB-II down (Internet MIB): Roaming directory from MIB-II

7. Displaying the meaning of the results Explanation:

These results Can clear , can also be saved or updated, to achieve the above functions, you can use the corresponding operations in the menu, specifically, these operations include:

Copy one or more results into the clipboard.

Delete all the content listed now.

Clear all commands that have been executed.

Request to record the currently selected project.

Generate a text file that will be used to save an image of all records

Edit or set the identity of an object. Be cautious when using this operation, because if it is set incorrectly, it may cause problems in network name resources or connectivity problems.

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