Sometimes you need a snmp source for testing something in checkmk. For this you can use snmp daemon.
This short manual is tested with Ubuntu 20.4 and not supported by Tribe29
sudo apt install snmpd snmp
The file /etc/snmp/snmpd.conf contains the configuration of SNMPD. To query the SNMP from different sources, comment the bellow line:
#agentaddress 127.0.0.1,[::1]
Restart the snmp service
/etc/init.d/snmpd restart
Now you can create a snmpwalk by using snmpbulkwalk. This will work local as well as remote
snmpbulkwalk -v2c -c public mysnmpdtesthost01
