Nut upsuser - May 2013 - APC AP9617 SNMP returns strange errors

Hi,

we do have APC Smart-UPS each with AP9617 and latest FW.

As we found out we are not able to shutdown the UPS via SNMP - neither
immediately nor delayed.  And we cannot set values, but we can read them
correctly.  So it seems as we are not able to write to the UPS and get back
strange errors.

root at abex:/etc/nut# upsdrvctl -DDDD shutdown apc10001
Network UPS Tools - UPS driver controller 2.6.4
   0.000000
If you're not a NUT core developer, chances are that you're told to
enable debugging [...]
   0.000280     Shutdown UPS: apc10001
   0.000304     exec:  /lib/nut/snmp-ups -a apc10001 -k
Network UPS Tools - Generic SNMP UPS driver 0.66 (2.6.4)
Detected Smart-UPS 1000 on host 10.100.200.30 (mib: apcc 1.1)
Initiating UPS shutdown
[apc10001] nut_snmp_set: can't set .1.3.6.1.4.1.318.1.1.1.6.1.1.0: Error in
packet: (genError) A general failure occured
Shutdown failed!
   0.099067     Driver failed to start (exit status=1)

If I use upscmd for shutdown it says "OK" but does nothing.
I sent an snmp command directly to the ups (1.3.6.1.4.1.318.1.1.1.6.2.1 i 2) and
the ups turned off as expected.

I tried to set values via upsset.cgi in the ups and see the following in the
logs even if the cgi says "ok":
May 15 09:54:30 abex upsd[7788]: Set variable: admin at 10.100.200.1 set
battery.charge.restart on apc10001 to 90
May 15 09:54:30 abex snmp-ups[7785]: [apc10001] nut_snmp_set: can't set
.1.3.6.1.4.1.318.1.1.1.5.2.6.0: Error in packet: (badValue) The value given has
the wrong type or length.

But I can read that value correctly.  We cannot set any values but read them
all.  community is ok as I can see auth messages in the ups if I use the wrong
community.  When get those errors above, I do not see any errors in the UPS'
logs.

I have no clue what's happening here.  I can see this on both UPS which have
1kVA and 1.5kVA and AP9617 (that is the same as AP9618 that is supported with
the exception of env montoring).

We are using Debain wheezy (not yet the stable) and nut 2.6.4-1 and snmp-stuff
5.4.3-dfsg-2.5.

Is there someone who can help, please?!

Thanks a lot,
-lutzn

The message that you trimmed was intended to explain that if you want more debug
messages, you need to call the driver directly with the -D flags, e.g.
"/lib/nut/snmp-ups -DDDD -a apc10001 -k".

Unfortunately, I am not familiar with the inner workings of the SNMP driver.
