Re: [SNMP4J] Unsupported security model

2010-06-23 Thread Kazantsev, Andrey V. 
I'm glad to hear that I helped you.

What user name do you mean? In fact there is only security name, which is first 
argument to UsmUser constructor. You use it later for adding this user to USM 
instance (usm.addUser(user.getSecurityName(), user)). I just called security 
name with username, but it could be arbitrary string.

  Hello

Thanks for your quick reply. I've tried your code and after five tries 
it now works. In fact I didn't understand that the username and the 
security name have to be equals (confirm?). But now it works fine.

Thanks again for your help
Have a nice day

 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\

Re: [SNMP4J] Unsupported security model

2010-06-23 Thread Gian Marco Gallo 
  I've done this:

UserTarget target = new UserTarget();
target.setSecurityName(new OctetString(CryptoExtWeb));

Then I've done this:

UsmUser user = new UsmUser(new OctetString(CryptoExtWeb), null, null, 
null, null);

In this way the code works fine and the trap is sent but if I use 
different OctetStrings this runtime exception is returned.

Yes, you right - in UserTarget you should use security name that is exist in 
USM - i.e., that you created with UsmUser. This tells what security settings to 
use when sending traps (you can create more than one UsmUser with different 
settings and use any of them in UserTarget).

I've searched for two days a solution in the snmp4j documentation and

I'm attaching my simple snmp class.

Thanks in advance
