Installing SNMP daemon and tools:
As root
yum -y install net-snmp.i686
yum -y install net-snmp-utils
Once these are installed start the snmp daemon:
/etc/init.d/snmpd start
chkconfig snmpd on
This is just the basic install but testing it :
snmpwalk -v 1 -c public -O e 127.0.0.1
For production servers it is advisable to at least change the community name.
All configs are in
/etc/snmp/snmpd.conf
and traps are setup here:
/etc/snmp/snmptrapd.conf
No traps are set by default.
Enjoy !!
