Re: AgentX problem

I am trying master agent and subagent from agentX library:
http://www.snmp4j.org/snmp4j-agentx-1.2.2.zip. Compiled them with Eclipse.
MasterAgent starting parameters: tcp:127.0.0.1/705 udp:127.0.0.1/705,
subagents starting parameters: 127.0.0.1/705
I am working on Win 7 OS.

Re: AgentX problem

This setup cannot work. The parameters for the master
agent define the SNMP listen addresses (not the
AgentX listen address). When you listen for SNMP
packets, you cannot listen for AgentX.

Basic test run question

I am new to the snmp4j and trying to test if I can run the simple program.

I took sample from SNMP class and created the following program that is
not working.  It compiles and runs with the outputs below.
Can anyone help me?

Re: Basic test run question

Everything is OK. You just encounter a timeout (no response
from the agent). Check the agent address and community.

SNMP4J Agent 1.3.2: NullPointer Exception when receiving GET requests with unknown community strings

Hi there,
I am trying to develop an SNMP agent capable of responding to V1 and V2c
requests with the help of SNMP 4J Agent framework version 1.3.2;
my community string is configured as "public"; any time the agent
receives a V2c GET request with a community string different from
"public", it hangs and the following exception is logged:

20091202 173258 CET [ERROR] <DefaultUDPTransportMapping> PTMA0000:

SNMPv3 Key Localization (repost)

Hi Frank

Sent this a few days back but have seen no response, it may well be that
I just need to read up more on the topic but the sample code is in
error:

I'm a little confused by SNMPv3 Key Localization and your example:

https://server.oosnmp.net/confluence/pages/viewpage.action?pageId=144180
0

snmp.getUSM().addLocalizedUser(engineID, sharedUserName,

    AuthMD5.getID(), new OctetString("md5Passphrase"),

    PrivDES.getID(), new OctetString("desPassphrase"));

In the example you call USM.addLocalizedUser(...) with OctetString
passphrases for auth & priv but as I understand the method these should
be byte[] passkeys.  And, indeed, the sample code will not compile.

These passphrases should be converted to passkeys.  I'm assuming this
should _not_ be by adding a simple getValue() (because how do I get
passkeys if not from passphrases), so should I instead be using

snmp.getUSM().addLocalizedUser(engineID, sharedUserName,

    AuthMD5.ID, 

    SecurityProtocols.getInstance().

Re: SNMP4J Agent 1.3.2: NullPointer Exception when receiving GET requests with unknown community strings

Hi Gianluca,

This is indeed a bug. Although it has no security
relevance, it has regarding authenticationFailure
trap generation and counter incrementation.

The below patch fixes it:

Index: SnmpCommunityMIB.java
===================================================================
--- SnmpCommunityMIB.java	(revision 1664)
+++ SnmpCommunityMIB.java	(working copy)
 <at>  <at>  -543,8 +543,10  <at>  <at> 
      if (coexistenceInfo == null) {
        return null;
      }
-    SortedSet cinfos = new 
TreeSet((SortedSet)coexistenceInfo.get(community));
+    SortedSet cinfos = (SortedSet)coexistenceInfo.get(community);
      if (cinfos != null) {
+      // make a copy to improve consistency on concurrent access
+      cinfos = new TreeSet(cinfos);
        Iterator it = cinfos.iterator();
        CoexistenceInfo[] infos = new CoexistenceInfo[cinfos.size()];
        for (int i=0; i<infos.length; i++) {

Best regards,
Frank

Re: SNMPv3 Key Localization (repost)

Hi Gary,

The example in the Wiki is indeed misleading. I have updated
it.
