Re: snmp v3 authentication

Thanx for the tip.

I had created the rwuser with net-snmp-config, but given the option I didn't 
specify a passphrase. That invalidated the snmpd.conf entry. I believe that 
authors should handle this point more elegantly. What is the use of creating 
a rwuser in snmpd.conf if it is not validated and therefore useless? Except 
maybe for the poor user who sees his name in snmpd.conf, gets a message 
"Unknown user name" and gets completely confused...

I would like to ask another question:
For snmpv3 authentication to complete I need to specify context with 
snmpvacm. When I try (as described in man pages):

snmpvacm -u xxx -A xxxxx -l authNoPriv localhost createSec2Group 3 xxx 
RWGroup

I get:

Error in packet.
Reason: inconsistentValue (The set value is illegal or unsupported in some 
way)
Failed object: SNMP-VIEW-BASED-ACM-MIB::vacmSecurityToGroupStatus.3."xxx"

If I try any other model other than 3 it succeeds. But according to man 
pages we are not allowed to use any other value than 3 (snmp v3).

BR,
Nikos
