How To Install and Configure an SNMP Daemon and Client on Ubuntu 14.04

Introduction

SNMP (Simple Network Management Protocol) is a widely used protocol for monitoring and managing network devices. It allows administrators to collect and view data about network devices such as routers, switches, and servers. In this tutorial, we will learn how to install and configure an SNMP daemon and client on Ubuntu 14.04.

Prerequisites

To follow this tutorial, you will need:

  • An Ubuntu 14.04 server
  • A user account with sudo privileges

Step 1 - Installing the SNMP Daemon

The SNMP daemon is the service that runs on the network device and collects data. To install the SNMP daemon, open a terminal and enter the following command:

sudo apt-get install snmpd

During the installation process, you will be prompted to enter a system contact and location. This information is used by the SNMP client to identify the network device. Enter the information and continue with the installation.

Step 2 - Configuring the SNMP Daemon

After the installation is complete, we need to configure the SNMP daemon to allow access from the SNMP client. Open the configuration file in a text editor:

sudo nano /etc/snmp/snmpd.conf

Find the line that says "com2sec notConfigUser default public" and change it to:

com2sec notConfigUser default mysecretpassword

This line sets up a community string that the SNMP client will use to authenticate with the SNMP daemon. Replace "mysecretpassword" with a secure password of your choice.

Next, find the line that says "#agentAddress udp:127.0.0.1:161" and uncomment it by removing the "#" at the beginning of the line. This line allows the SNMP daemon to listen for requests on the network.

Save and close the configuration file.

Step 3 - Restarting the SNMP Daemon

After making changes to the configuration file, we need to restart the SNMP daemon to apply the changes. Enter the following command:

sudo service snmpd restart

The SNMP daemon is now configured and running on the Ubuntu server.

Step 4 - Installing the SNMP Client

The SNMP client is the software that is used to access and view data collected by the SNMP daemon. To install the SNMP client, enter the following command:

sudo apt-get install snmp
