Hi, I had a similar problem, I was getting a "Unknown security name" from USM. I checked that the user was added correctly, and it was, but after doing some debugging I noticed I was using a different USM. My error was I was doing initialization twice in my application with different USM (one with a UsmUser, the other one without a UsmUser). In one place, I was calling:
final USM usm = new USM(SecurityProtocols.getInstance(), new OctetString(MPv3.createLocalEngineID()), 0); SecurityModels.getInstance().addSecurityModel(usm); snmp.getUSM().addUser(new OctetString(securityName),new UsmUser(new OctetString(securityName),...)); and a bit later: final USM usm = new USM(SecurityProtocols.getInstance(), new OctetString(MPv3.createLocalEngineID()), 0); SecurityModels.getInstance().addSecurityModel(usm); Since SecurityModels is a singleton, I was losing the USM with the configured user, that's why I was getting "Unknown security name" when checking security against the other (the one without UsmUser). I solved it by doing a single init call to SecurityModels.getInstance().addSecurityModel(usm) for the whole application.
