Installation of the SNMP daemon
apt-get install snmpd
Create a backup of the SNMP configuration file
cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.orig
Adjust the configuration
Next, edit /etc/snmp/snmpd.conf and perform the changes below.
For the simplest possible configuration
- Comment-out (using #) or simply delete all lines from the original file
- Add the lines below and make sure they are not commented. If you don’t use IPv6, you don’t need to add the IPv6 setup.
# IPv4 setup
agentaddress udp:161
rocommunity public 0.0.0.0/0
# IPv6 setup
agentaddress udp6:161
rocommunity6 public ::/0
Save changes and restart the snmpd service
sudo systemctl restart snmpd.service
