[snmpsim-users] v3 GETs failing to select proper controller

[Forman, A. <And...@Te...>]

Hi, I'm at a complete loss as to what I've screwed up.

Previously, I had no trouble accessing the data in my .snmprec files over v2c or v3.
But today, I found that while my v2c GETs still work fine, my v3s are all failing.

When I make a v2 call, I get the data and see logging entries like this:

2013-09-27 16:32:50.957 snmpsimd[3164]: Using ./data\MYMIB.snmprec controller selected by contextName "e5d93d7d01f1414254094c14fa19bd92", transport ID 1.3.6.1.6.1.1.0, source address 127.0.0.1

When I make a v3 call to the same OID as the v2, I get this:

2013-09-27 14:52:06.388 snmpsimd[16605]: Using /usr/lib/python2.4/site-packages/snmpsim-0.2.3-py2.4.egg/snmpsim/data/1.3.6.1.6.1.1.0/127.0.0.1.snmprec controller selected by candidate 1.3.6.1.6.1.1.0/127.0.0.1; transport ID 1.3.6.1.6.1.1.0, source address 127.0.0.1, context name "b00e7c4780fffc4ca0a74e262dd116bc"

My command line looks like:

snmpsimd.py --data-dir=./data --variation-module-options=writecache:file:./data/sets.db --agent-udpv4-endpoint=localhost:1611 --v3-user=user --v3-auth-proto=NONE --v3-auth-key=ThePassword --v3-priv-proto=NONE --v3-priv-key=ThePassword --logging-method=file:./snmpsim.tmp

I've tried both the latest RC and the last formal release, but see no difference in behavior.
Any chance you can tell what I've messed up?

Thanks!
Andrew
