Net-SNMP

Net-SNMP is a suite of applications used to implement and deploy SNMP (Simple Network Management Protocol) protocol versions v1, v2c, and v3, as well as the Agent Extensibility (AgentX) protocol. It provides tools for collecting and managing information about networked devices and systems.

The Net-SNMP project consists of several key components, including:

• An SNMP agent: This runs on the managed device and responds to SNMP requests from management stations. It provides access to information about the device's status, configuration, and performance.

• A command-line toolset: This allows administrators to query and manage devices running the Net-SNMP agent. Common tools include snmpget, snmpwalk, snmpset, and snmptrap. These tools facilitate querying for specific values, traversing the Management Information Base (MIB) hierarchy, setting device parameters, and receiving trap notifications.

• A graphical user interface (GUI): While Net-SNMP is primarily command-line driven, some front-end GUI applications exist that utilize Net-SNMP's functionality.

• A libraries API: Developers can use the Net-SNMP libraries to integrate SNMP functionality into their own applications. This allows for customized network management solutions.

Net-SNMP supports a wide variety of operating systems, including Linux, Windows, and Unix-like systems. It is an open-source project distributed under a BSD-style license, making it freely available for use and modification.

The primary purpose of Net-SNMP is to facilitate network monitoring and management. By providing a standardized way to access device information, Net-SNMP allows administrators to proactively identify and resolve network issues, optimize performance, and maintain overall network health. It provides a critical function in IT infrastructure management.

The project is actively maintained, with regular updates and bug fixes. Its popularity is due to its comprehensive feature set, platform support, and open-source nature.
