snmpd is run from init.d, launched by start-stop-daemon. The default mode is
SNMPv3. V1, V2c are not used.

I cannot accomplish the first step to setting trap configs using snmpset.
However, if I mimic the trap-destination steps on an external linux host
(Intel / Fedora23) to the target, it works fine.
Here's the host side output:

SNMP-TARGET-MIB::snmpTargetAddrRowStatus.'testTarget' = INTEGER: destroy(6)
>From Fedora host, systematically configuring the table works to the degree
that I can use a mib browser in V3 to look at my target's snmpTargetAddr
table entries, and they return the applied content.
That entire initial volley consists of:
snmpset -d -Lo -M ../mibs -m ALL -v3 -l authpriv -u SNMPv3ShaAesUser -a SHA
-A password -x AES -X password 10.11.16.93
snmpTargetAddrRowStatus.\'testTarget\' i 6

snmpset -d -Lo -M ../mibs -m ALL -v3 -l authpriv -u SNMPv3ShaAesUser -a SHA

-A password -x AES -X password 10.11.16.93
snmpTargetAddrRowStatus.\'testTarget\' i 1
But the same exercise, when run from the target's shell doesn't work.
Here's the target side output (to any of its eth0 IP, lo, localhost,
127.0.0.1):
/usr/sbin/snmp-support/scripts # snmpset -d -Lo -M ../mibs -m ALL -v3 -l
authpriv -u SNMPv3ShaAesUser -a SHA -A password -x AES -X passphrase
10.11.16.93 snmpTargetAddrRowStatus.\'testTarget\' i 6
snmpTargetAddrRowStatus.'testTarget': Unknown Object Identifier
(snmpTargetAddrRowStatus.'testTarget')
That's all I get, no matter what I try (so far).
../mibs/ on both the target and the Fedora host are the same content:
-rwxrwx---. 1 root root 68104 Apr 27 11:41 DISMAN-EVENT-MIB.txt

-rwxr-x---. 1 root root 38034 Apr 27 11:42 SNMPv2-TC.txt
I am running as root in both places as well (don't have a choice on the
target).
Any ideas? I'm all out of them.
thanks.
