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 is not supported by Checkmk.
root@linux# 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 below line:
/etc/snmp/snmpd.conf
#agentaddress 127.0.0.1,[::1]
Restart the snmp service.
root@linux# /etc/init.d/snmpd restart
Now you can create a snmpwalk by using snmpbulkwalk. This will work local as well as remote.
root@linux# snmpbulkwalk -v2c -c public mysnmpdtesthost01
