For me, I follow these steps:
1. I use the config file example from ppalias, put it into /Database/opt/x.x/packages/share/snmp/snmpd.conf
2. and then add these lines to the “Post Boot” startup script:
# Start the SNMP Service
It may not be a good method, but it works for me at this moment! The snmp service will auto run when the zeroshell start, and I can query the snmp values from a remote host.
