Hi,
I'm using pysnmp v4 to interact with a network device using SNMPv3.
I can successfully make queries using the snmp command. However
following the examples available in the Documentation I get the
following error: unknownEngineID
Here is the relevant code:
errorIndication, errorStatus, errorIndex, varBindTable =
cmdgen.CommandGenerator().nextCmd(
cmdgen.UsmUserData('user', 'xxxx',
'xxxx',cmdgen.usmHMACSHAAuthProtocol, cmdgen.usmDESPrivProtocol),
cmdgen.UdpTransportTarget(('192.168.2.1',161)),
(1,3,6,1,2,1,1)
)
print errorStatus
print errorIndication
for varBindTableRow in varBindTable:
print varBindTableRow
And the output is:
0
unknownEngineID
If I do the same query using the snmpwalk command it behaves as
expected.
(snmpwalk -v3 -l authPriv -u user -x DES -a SHA -A xxxx -X xxxx
192.168.2.1 1.3.6.1.2.1.1)
So.. anybody can explain me what that error is?
Thank you for your time,

That error might mean that your SNMP engine fails to discover peer SNMP
engine for some reason. In attempt to figure out the cause I'd suggest
enabling SNMP security module debugging by adding the following in the
beginning of your script:
from pysnmp import debug
debug.setLogger(debug.Debug('secmod'))
That would enable stderr reporting. I'd appreciate you sending me the
output for a single failed GETNEXT session.
Also, try using pysnmp code from CVS -- there were some minor fixes,
though I'm not sure how relevant they are to this problem.
BTW, does pysnmpwalk tool (from pysnmp-apps package) fails in the same
way?

Hi,
I haven't tried the CVS version yet.
I'm using pysnmp 4.1.7a-1 from debian unstable.
Here is the script I'm using to test this:
------------------------- script ---------------------------
#!/usr/bin/python
from pysnmp.entity import engine
from pysnmp.entity.rfc3413.oneliner import cmdgen
from pysnmp import debug
debug.setLogger(debug.Debug('secmod'))
usmData =3D cmdgen.UsmUserData('user', 'XXXX', =20
'XXXX',cmdgen.usmHMACSHAAuthProtocol, cmdgen.usmDESPrivProtocol)
udpTransport =3D cmdgen.UdpTransportTarget(('192.168.249.1',161))
errorIndication, errorStatus, errorIndex, varBindTable =3D =20
cmdgen.CommandGenerator().nextCmd(
usmData,
udpTransport,
(1,3,6,1,2,1,1)
)
print errorStatus
print errorIndication
=09
for varBindTableRow in varBindTable:
print varBindTableRow
------------------------- /script ---------------------------

Issuing the exact same command replacing "pysnmpwalk" with "snmpwalk" =20=
works fine.

Just an update. I have tested pysnmpwalk with another server that's using SNMP v1/v2c and it works fine with that one. Maybe it's the encryption stuff that's causing this? Paulo F.

It's surely a fault of SNMPv3 security module, so it won't fail in SNMPv1/v2c mode. > Just an update. I have tested pysnmpwalk with another server that's using > SNMP v1/v2c and it works fine with that one. > > Maybe it's the encryption stuff that's causing this? |

Could you please enable 'msgproc' debugging as well:
debug.setLogger(debug.Debug('secmod', 'msgproc'))
and send me the output?
So far I suspect your SNMP Agent may respond from an address endpoint
other than you used for sending requests.
Thanks,
ilya
