How To Install and Configure SNMP on CentOS II. Introduction SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, servers, and more, all via IP. In this case, we’ll be installing an SNMP agent on a CentOS 6.5 server, which will allow for collection of data from our server, and make the information available to a remote SNMP manager. Pre-Flight Check • These instructions are intended for installing SNMP and doing a very basic configuration. • I’ll be working from a Liquid Web Core Managed CentOS 6.5 server, and I’ll be logged in as root.

Install SNMP and SNMP Utilities Installing SNMP and some optional SNMP utilities is as simple as running one command: yum -y install net-snmp net-snmp-utils Add a Basic Configuration for SNMP Now, let’s take the default SNMP configuration file, /etc/snmp/snmpd.conf and move it to an alternate location, /etc/snmp/snmpd.conf.orig. Mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.orig And now we’ll create a new /etc/snmp/snmpd.conf: vim /etc/snmp/snmpd.conf. Note: SNMPv2c contains some security enhancements over SNMPv1 but uses the existing SNMPv1 administration structure, which is “community” based. Areas of improvement include: transport mappings, protocol packet types, and MIB structure elements. In the first scenario: ConfigUser is assigned to ConfigGroup and may only use SNMP security model 2c, ConfigGroup can use the SystemView, SystemView is assigned to two OID sub-trees, and all of this is referenced in an SNMP poll by the secret, and unique community string idv90we3rnov90wer. In the second scenario: AllUser is assigned to AllGroup and may only use SNMP security model 2c, AllGroup can use the AllView, AllView is assigned to the entire OID tree, and all of this is referenced in an SNMP poll by the secret, and unique community string 209ijvfwer0df92jd.

Important Tip: Be ABSOLUTELY SURE that you choose a unique community string and replace the community strings in the above examples. Keep each secret, and keep each safe.
