Hello guys.

I installed net-snmp (5.3.1), enabled SNMPv3 access control and I can
happily access an SNMP agent.

However:

[user@computer directory]# snmpwalk -u user -a MD5 -A password -x DES -
l authNoPriv localhost udp

And:

[user@computer directory]# snmpwalk -u user -a MD5 -A password -x DES -
l authNoPriv localhost udpInDatagrams
UDP-MIB::udpInDatagrams = No Such Instance currently exists at this
OID

I am a newbie to SNMP and I'm comletely out of ideas. I was trying to
google anything on the problem. No success.

Any suggestions?
