Configure SNMP for RHEL 6
SNMP is a very powerful and useful tool to add to your Linux system. It is great for sending alerts to different monitoring systems like Nagios and many other great products. But first it needs to be installed and configured before you can put this under rated tool to work.
Install SNMP using yum, you will need net-snmp-utils, net-snmp, net-snmp-libs.
$ sudo yum install –y net-snmp-utils net-snmp net-snmp-libs
Now that we have snmp it is time to configure SNMP.
Edit file /etc/snmp/snmpd.conf using your favorite text editor, mine just happens to be vi.
$ sudo vi /etc/snmp/snmpd.conf
Change/Modify line(s) as follows:
Find following Line:
com2sec notConfigUser default public
Replace with (make sure you replace 192.168.0.0/24 replace with your network IPs) following lines:
com2sec local localhost public
com2sec mynet 192.168.1.0/24 public
Find and change the lines.
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
Replace with:
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
group MyROGroup v1 mynet
group MyROGroup v2c mynet
group MyROGroup usm mynet
Locate and change the following line.
view systemview included system
Replace with.
view all included .1 80
Locate and change the following line.
access notConfigGroup “” any noauth exact systemview none none
Replace with.
access MyROGroup “” any noauth exact all none none
access MyRWGroup “” any noauth exact all all none
Locate and change the following lines.
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root (configure /etc/snmp/snmp.local.conf)
Replace with your credentials.
syslocation RHEL 6, Linux Server.
syscontact sysadmin <root@localhost>
Now let’s start your snmp server and test it.
Set the snmpd service to start on reboot or system start.
$ sudo chkconfig snmpd on
Fire it up !!
$ sudo service snmpd start
Test your snmp server
# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex
