Check the contents of your pandora_snmptrap.log. They should look something like:
tail -f /var/log/pandora/pandora_snmptrap.log
If you have “No access configuration – dropping trap.” lines it’s because you haven’t configured the snmptrapd daemon access. Use these commands to solve the problem:
echo "authCommunity log public" >> /etc/snmp/snmptrapd.conf
/etc/init.d/pandora_server restart
This should be a functional fix for this issue.
