Ok,
So it appears that I should add:
trapsess -e 0x80001F888001331F10B729FA5E00000000 -Ci -v3 -u
remoteUser -l authPriv 192.168.1.215
to /etc/snmp/snmpd.conf for v3 informs (without the -Ci for v3 traps), and:
createUser -e 0x80001F888001331F10B729FA5E00000000 remoteUser SHA
"authPass" AES privPass
in /var/lib/snmp/snmpd.conf where "0x80001F888001331F10B729FA5E00000000"
is the engine-id of the receiver.
Does that look right? Will that work correctly?
