[mrtg] cfgmaker with snmp3 bintec - authentification

[uve.hayden.lists at quirlum.de]

Hi - I'm in a dead end:

I like to observe a BINTEC-router with mrtg.
I tried this:
#snmpwalk -v 3 -a MD5 -u read -A secretword -l authNoPriv 192.168.33.254
output:
SNMPv2-MIB::sysDescr.0 = STRING: X2302

SNMPv2-MIB::sysObjectID.0 = OID:
SNMPv2-SMI::enterprises.272.4.200.83.88.50.49.0.0

DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (678656500) 78 days,
13:09:25.00

SNMPv2-MIB::sysContact.0 = STRING: BINTEC

SNMPv2-MIB::sysName.0 = STRING: r01.quirlum.de

....list of the sensors...

o.k. - then this:
# cfgmaker read at 192.168.33.254:161::::3
output:
SNMP V3 requires a --username parameter as part of the User Security

ok. - cfgmaker know to use the protocol v3 - then this:
cfgmaker --username=`read` --authpassword=`secretword` 
--authprotocol=`md5` 192.168.33.254:161::::3
output: nothing - no reaction...

Thanks!- Uve Hayden
