Hi Bosecorp,

I was able to upgrade my Linux machine from SNMPv2 to SNMPv3 without a problem.

Start by creating a backup of the original /etc/smp/snmpd.conf file

Code: Select all

cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.bak

Stop the the SNMP service while adding SNMPv3.

Code: Select all

systemctl stop snmpd.service

Use the following command to create the SNMPv3 user which will be added to the /etc/snmp/snmpd.conf and the /var/lib/net-snmp/snmpd.conf. Replace the necessary passwords, username, and authentication types.

Code: Select all

net-snmp-create-v3-user -ro -a SHA -A Str0ng@uth3ntic@ti0n -x AES -X Str0ngPriv@cy nagios

Then restart the service.

Code: Select all

sudo systemctl start snmpd.service

In the XI GUI, you would have to re-monitor the devices that have been upgraded to SNMPv3.
