Hi there!.
I tried the NoAuthNoPriv option as well ( no authentication or encryption - the
username has to just exist at the agent) - no luck...the router debugs
indicate the username is not being passed....
Does Net-SNMP really support V3? has anyone tried it ????

I am trying to establish an snmpv3 session with a cisco router using the
cricket monitoring system. I am trying to do it using the authNoPriv level.
While, I can get snmpwalk etc to work from the monitoring box (RH linux) to
the router, I cant get the snmpsession to open with perl.
When i run the collector, I see that the snmp session pointer is being set. But
when I debug snmp headers at the router end, it shows that though a snmp v3
packet is received, the security level is set to "noauth" and there is no
username as well.
I am quite stumped, as I can do the snmpwalk -v 3 perfectly fine.
Running the collector indicates a timeout.
When I print these variables in SNMP.pm, my values appear correctly.
$this->{SessPtr} = SNMP::_new_v3_session($this->{Version},
$this->{DestHost},
$this->{Retries},
$this->{Timeout},
$this->{SecName},
$this->{SecLevel},
$this->{SecEngineId},
$this->{ContextEngineId},
$this->{Context},
$this->{AuthProto},
$this->{AuthPass},
$this->{PrivProto},
$this->{PrivPass},
$this->{EngineBoots},
$this->{EngineTime},
);
Any help will be appreciated
Ajay
