snmpd can be royal pain to configure. I got my hints from Ryan Steinmetz, the maintainer for the FreeBSD port. Lately, net-snmpd has changed how net-snmp-config works. In this post: FreeBSD 12.2 net-snmp-5.9_3,1 Compare my hints with the following, run today with net-snmp-5.9_3,1: [dan@nginx01:~] $ sudo net-snmp-config –create-snmpv3-user -ro -x AES -a SHA -A ‘secret123’ […]
