Thanks Colin,
I'm trying to avoid the clear-text passwords on the trapsess line.
For traps, I have:
createUser trapUser SHA authPass AES privPass
in /var/lib/snmp/snmpd.conf, and
trapsess -v3 -u trapUser -l authPriv 192.168.1.215
in /etc/snmp/snmpd.conf.
And it works. The traps are properly authenticated and encrypted (I'm
testing with wiershark).
However, I still can't get the informs to work without clear text
passwords on the trapsess.
I still need help.
