1. Installation :
Run command yum install net-snmp-utils. It should install net-snmp as a dependency
2. Configure :
Backup the snmpd config file. mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.org
Create a new config file. vi /etc/snmp/snmpd.conf
rocommunity public
syslocation "Your location"
syscontact <your email>
Start the snmpd service : /etc/init.d/snmpd start
Do a snmpwalk to make sure it is working : snmpwalk -v 1 -c public -O e 127.0.0.1
Make sure snmpd starts next time you restart your machine : chkconfig snmpd on
Your Linux box will show up as net-snmp rather than as Linux or the dreaded UNKNOWN.
