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.
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.
