Re: How to add SNMP-TSM-MIB to snmpd

Thanks for the suggestion, I am assuming you meant that the snmpget needed
a -v 3 to do version 3 snmp.
That did not work and I tried with USM and TSM models:

bash-4.3# snmpget -v 3 -u v3admin -a md5 -A hello1234 -l authNoPriv
127.0.0.1 1.3.6.1.2.1.190.1.2.1.0
SNMP-TSM-MIB::snmpTsmConfigurationUsePrefix.0 = No Such Object available on
this agent at this OID

bash-4.3# snmpget  -v 3 --defSecurityModel=tsm -T
our_identity=04:BF:CF:1A:9C:5D:7A:9D:87:7E:1D:D8:A3:77:1A:DD:D7:76:77:0B -T
their_identity=07:96:45:D7:46:E4:EE:11:66:68:36:77:A5:F9:24:D6:8A:1A:71:D9
dtlsudp:127.0.0.1:10161 1.3.6.1.2.1.190.1.2.1.0
SNMP-TSM-MIB::snmpTsmConfigurationUsePrefix.0 = No Such Object available on
this agent at this OID

I see in the snmpd output at start up time:
Nov 15 10:05:33 apcon-ubuntu snmpd[14186]: A SNMP version other than 3 was
requested with (D)TLS; using 3 anyways

I feel this is either a build/configuration issue with snmpd that I am not
addressing.
Like I said, I added to the mib in the build configuration option and have
installed it.
Just seems like I am missing something to tell snmpd that it is responsible
for this MIB.
