LINUX: How do I enable SNMP on Ubuntu

As always, I seem to forget things, among theese is the SNMP setup for Ubuntu, so now, for myself to remember, I created this little guide 🙂

This is btw. run on a Ubuntu Server 20.04 LTS

Run the following commands on the terminal:

1. Update all packages: sudo apt-get update
2. Install SNMP: sudo apt-get install snmpd
3. Edit snmpd.conf with text editor of your choice, I will be using nano, as this is an easy editor, so type: sudo nano /etc/snmp/snmpd.conf
4. Configure agentAddress: agentAddress udp:161,udp6:[::1]:161
   -This will set the server to listen on all IPv4 and IPv6 addresses (remove the ‘#’ in front of the agentAddress, to enable it!)
   – To bind it to a specific IP address use (ex.): agentAddress udp:192.168.1.5:161
5. Configure rocommunity: rocommunity public
   -Change “public” to your community name
6. Restart the SNMPD service: sudo service snmpd restart
7. Check that SNMPD is started OK with this: sudo service snmpd status

All good! – Now go setup your favorite monitoring tool for SNMP access 🙂
