Raspberry Pi – enabling SNMPv2

# apt-update -y
# apt-get install -y snmpd snmp
# systemctl stop snmpd

Edit the file vi /etc/snmp/snmpd.conf and change the following

These three lines are the default
agentAddress udp:127.0.0.1:161
rocommunity public default -V systemonly
rocommunity6 public default -V systemonly

I changed to these lines
agentAddress udp:192.168.1.159:161
rocommunity SuPerSecr3t default -V systemonly
# rocommunity6 public default -V systemonly

# snmpwalk -v 2c -c SuPerSecr3t 192.168.1.159
