[SNMP4J] FW: Unsupported security model

[Kazantsev, Andrey V.]

Hello.

I think you should create USM (User Security Model) and add it to your SNMP session. Consider following example:

USM usm = new USM(SecurityProtocols.getInstance(), new OctetString(MPv3.createLocalEngineID()), 0);
SecurityModels.getInstance().addSecurityModel(usm);

Also you maybe want to add user (noAuthNoPriv):
user = new UsmUser(new OctetString("username"), null, null, null, null);
usm.addUser(user.getSecurityName(), user);

This example code from http://www.snmp4j.org/doc/org/snmp4j/Snmp.html

Also you can look at SnmpRequest.java from snmp4j-1.11.zip\snmp4j-1.11\src\org\snmp4j\tools\console\

I've searched for two days a solution in the snmp4j documentation and over internet but no luck. Do you have an idea?
I'm attaching my simple snmp class.

Thanks in advance
