Now that we have a new user specified, we need to set up the level of access that this user will have. Our user creation line will look like this: createUser bootstrap MD5 temp_password DES If no privacy protocol passphrase is supplied, the authentication passphrase will be used for the privacy protocol as well. If you plan on using encryption for the transfer, like we are, you also must specify the privacy protocol (DES or AES) and optionally a privacy protocol passphrase. When defining a new user, you must specify the authentication type (MD5 or SHA) as well as supply a passphrase that must be at least 8 characters. The SNMP packages do this through a process of cloning the userвЂ™s properties. The user we are creating will be called bootstrap and will be used as a template in which to create our first вЂњrealвЂќ user. These directives are not normally kept in this file, but we will be removing it again in a moment, so it doesnвЂ™t matter too much. Next, we will need to temporarily insert a createUser line. # Listen for connections on all interfaces (both IPv4 *and* IPv6) We need to comment out the current line, and uncomment the line underneath, which allows all connections (we will be locking this down soon): # Listen for connections from the local system only Currently, it is set to only allow connections originating from the local computer. These will mainly be used to bootstrap our configuration so that we can manage it from our other server.ДЇirst, we need to change the agentAddress directive. Inside, we will have to make a few changes. To get started, on our agent computer, we need to open the daemonвЂ™s configuration file with sudo privileges: sudo nano /etc/snmp/nf We can modify some configuration files to make some changes, but most of the changes we need to make will be done by connecting to our agent server from our management server. Configuring the SNMP Agent MachineДЄs a true client-server system, the agent computer does not have any of the external tools needed to configure its own SNMP setup. We are now finished configuring the manager portion, but we will still need to use this server to help us configure our agent computer. Save and close the file when you are finished. To allow the manager to import the MIB files, we simply need to comment out the mibs : line: #mibs : In this file, there are a few comments and a single un-commented line. Open the /etc/snmp/nf file in your text editor with sudo privileges: sudo nano /etc/snmp/nf We just need to modify one file to make sure that our client can use the extra MIB data we installed. Configuring the SNMP ManagerДЄs we mentioned above, most of the bulk of the work happens in the agent component, so our configuration is actually pretty easy on this machine. Now that you have installed these components, we need to configure our setup.

On our second server, the one that we will be interacting with that will run the daemon, we can install the necessary components by typing: sudo apt-get update Sudo apt-get install snmp snmp-mibs-downloader

Along with this, we will also download another package called snmp-mibs-downloader which contains some proprietary information about standard MIBs that allow us to access most of the MIB tree by name: sudo apt-get update

On the first server, update the apt database and install the manager component. We could choose to install the agent on the manager machine as well, but keeping them separate makes it easier to demonstrate what functionality is provided by each component. We will use two servers, one will contain the manager portion, while the other server will have the agent. We can begin to explore how SNMP can be implemented on a system by installing the daemon and tools on some Ubuntu systems. We will be using two Ubuntu 14.04 servers to demonstrate, but most other systems should be able to follow along with a few modifications.

In this guide, we will begin to demonstrate how to setup the tools to communicate using SNMP. In our last guide, we learned about the basics of the SNMP protocol. While the protocol itself is very simple, the structure of programs that implement SNMP can be very complex. It is a way that servers can share information about their current state, and also a channel through which an administer can modify pre-defined values. SNMP stands for simple network management protocol. Many of them are built upon a technology called SNMP. There are a number of tools and options for gathering and processing this type of information.

A large part of being a system administrator is collecting accurate information about your servers and infrastructure.
