To install Net-SNMPon Red Hat, use the following command:

yum install net-snmp rsync

Other Linux versions

To install the Net-SNMPpackage on your Linux distribution, use the standard system package manger. The fio-snmp-mibpackage places MIB files in /usr/share/fio/mib directory.

Configuring the SNMP master agent

You can configure the Net-SNMPmaster agent daemon to set the network communications parameters, security, and other options by using the snmpd.conf text file. The location of this file is system-dependent and customarily found in the following directory:

/etc/snmp or /usr/share/snmp.

A simple snmpd configuration file might include the following:

#set standard SNMP variables syslocation "Data room, third rack" syscontact itguy@example.com

#required to enable the AgentX protocol master agentx

agentxsocket tcp:localhost:16101

#set the port that the agent listens on (defaults to 161) agentaddress 161

#simple access control (some form of access control is required) rocommunity public

Running the Master Agent

After you install and configure the master agent, you must start or restart the snmpd daemon for the new parameters to take effect. You can run snmpd from the installed location (customarily located in the /usr/sbin directory. For options, see the snmpd manpage). To run properly, the snmpd daemon typically needs root privileges. You can also use the snmpd startup script in the

/etc/init.d or /etc/rc.d/init.d directory. For additional security, use the advanced SNMPv3 access control instead of the rocommunity and rwcommunity access control directives as outlined in the relevant manpage.
