Configuring Linux SNMP Daemon (Net-SNMP SNMPD) for SNMPv3

The first step is to enable SNMPv3 on in the /etc/snmp/snmpd.conf file, then restart the daemon.

Required Linux SNMPD Configuration for SNMPv3 communication to NMIS8

Add the following configuration to the top, edit the /etc/snmp/snmpd.conf file as the root user, e.g.

sudo vi /etc/snmp/snmpd.conf

Add the following configuration replacing the username and passwords is you require.

createUser nmis8 MD5 nmis4242 DES nmis4242
rouser nmis8 priv 1.3.6.1

The commands above will create a user called nmis8, with an authorisation password of nmis4242 and a privilege password of nmis4242

The view of 1.3.6.1, will permit access to the Standard MIB and the Enterprise MIB, essentially providing full access.

Restart the SNMP Daemon

sudo service snmpd restart

Testing your SNMPv3 Configuration with NET-SNMP

To verify that SNMPv3 is working as configured run the following command.  Change the username and passwords if you have used different ones.
