I am a Westhawk SNMP stack newbie and I develope an application that includes an snmp trap listener that listens for all incoming snmp traps. I have a question of theoretical nature. Why don't the SnmpContext classes have a constructor that does not take any argument? I tested a bit, and did not see any reason why I can't use the same context, created with "new SnmpContext("any valid ip address",any_port) and let it decode all the undecoded incoming SNMPv1 traps?

The stack was originally written for manager applications and traps were added later. For that reason each SnmpContext needs a host and port number. Although your solution might work for SNMPv1 and SNMPv2c, it does not work for SNMPv3, due to the number of parameters (authentication and privacy) that you need to decode a message. Your solution implies that you do not want to do any checking on the trap packet. The IP Address and community name are completely ignored. It is subject to debate whether this is correct or not. It might be easy programming, but I (personally) do think it is wrong. I admit SNMPv1 and v2c are not very secure anyway; it only has the community name. I don't know either how your application could be affected by a 'false' trap packet. We have been debating how to improve the stack when it comes to listening from incoming packets (both traps and requests). We are not sure yet how, but it would be nice to be able to configure hostnames and/or community names that are accepted. This requires a whole different setup, specially if it has got to work for SNMPv3 as well. Since paid projects have a higher priority, this might take some time. I know that none of the above will help you right now. The Stack Usage (html) document describes how to receive all incoming traps. If you still want to accept every trap packet that comes your way, you can copy bits and pieces from the stack source code and write your own context that does implements processIncomingTrap(byte[] message).

The 'community name' is not a PDU parameters, therefore we moved it (long time ago) to the context. Again, I don't understand your question, but I doubt that the SnmpContext should have 'specific' PDU 'parameters'. The SNMPv1 Trap format and the SNMPv2c (& v3) Trap format are different. In Trapv1 you can use the following methods to set parameters: setEnterprise(java.lang.String var) setGenericTrap(int var) setIpAddress(byte[] var) setSpecificTrap(int var) setTimeTicks(long var) There are no other 'parameters', but you can add varbinds to the varbind list (use addOid(xxx)). In Trapv2 the first 2 OIDs are mandatory (see examplev2c.SendTrap or read the RFC), but you can add as many OIDs to the varbind list as you want. Does this answer your question?

For example: addOid(java.lang.String oid, AsnObject val) Strings are represented by AsnOctets.

It can be used for Octets, Ip Addresses and Opaque types". Are not hint that you should use it on order to add varbind with String value. Anyway thanks for the prompt answer.

It is ages ago that we wrote it, and we have not really used it since. I'm afraid you are going to have to change the code, if you want the graph to be transparent. You best read about Component.isOpaque() and JComponent.setOpaque(boolean isOpaque). All the best, Birgit ps If you are going to make changes, please do not hesitate to email the code back to us when you are happy with it. Please do email us personally (snmp@westhawk.co.uk), because the mailing list does not accept attachments.

I don't think Rich's solution will work as stated, because in many situations there are many outstanding PDus, if you can't decode the packet and read the pduid, then it isn't clear who to throw the exception to. The best you can do is to narrow it down to the context. We can either throw exceptions to all the inflight pdu's in the context (overkill I'd say) or add a contextEvent which is fired to all listeners when a packet arrives on our socket that we are not expecting or can't decode.

There are 2 cases: 1) Listening for Traps - you'd be right there - except that it is 162, and the whole trap infrastructure uses listeners and events, not update, and no one _ever_ blocks waiting for a trap. If we get a packet to 162 we can't decode we just drop it (I think). 2) Listening for a reply to a set or get request we sent to an agent - Here the port we are listening on is a High numbered port, specific to the agent host. You'd have to send a to do your netcat with the right port number and get in before the _real_ answer has been received. What's more I think you'd have to run the netcat on the agent system, and set the source port to 161! >> >>A solution to this problem that springs to mind is to add an addition >>public static flag to one of the classes in the stack that specifies >>whether the stack should catch the generic Exception class or whether it >>should allow it to propogate to the calling application (by rethrowing >>it possibly inside a wrapper exception class).

There is the 'contextEngineID' and the 'snmpEngineID'. As the word 'discovery' says: the snmpEngineID is discovered, and therefore NOT configured! Your output below show no problem with discovery. In both cases the timeline is set just fine. In other words, this email is about misconfiguration of the contextEngineID. ** I'm addressing the whole mailing list now .. ** SNMPv3 is difficult, please read up on it!! ** Re 'no' contextEngineID: Note that even when you do not configure a contextEngineID, the SNMPv3Context will fill in a default of 'byte[0]'. Your context (user MD5) is configured to use authentication. Because the authoritative engine found a fault with the message, it can only send a response back without authentication and privacy. Our stack fails to decode the message, because it does not match the context, so you get a decoding exception. BTW: OID 1.3.6.1.6.3.11.2.1.2.0 = snmpInvalidMsgs.0 ** Re the endless loop (wrong contextEngineID): > 1.3.6.1.2.1.11.32.0: 2890 > ... (snmpProxyDrops = 1.3.6.1.2.1.11.32) The mib (see module SNMPv2-MIB) says (as you could have found out searching the web): snmpProxyDrops OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The total number of GetRequest-PDUs, GetNextRequest-PDUs, GetBulkRequest-PDUs, SetRequest-PDUs, and InformRequest-PDUs delivered to the SNMP entity which were silently dropped because the transmission of the (possibly translated) message to a proxy target failed in a manner (other than a time-out) such that no Response-PDU could be returned." ::= { snmp 32 } so apparently every PDU you send is dropped. That is why there comes no end to this get_next loop. Please realise that the stack is not responsible for the way the authoritative engine handles incoming requests. You are responsible for the correct parameters in SNMPv3. You should not be surprised it does not work when you use a wrong one. ** Re the archive: We've only started this mailing list, so that is all the archive there is. Hopefully it will grow rapidly. :-) Hope this helps, Birgit > Hello SNMP team, > > I have a question to discovery the snmp engine id. > > As the documentation describes, the class SnmpContextv3 > performs discovery of the SnmpEngineId. > I use the example uk.co.westhawk.examplev3.get_next.java. > > * If I configure the correct SnmpEngineId in the property file > the example works fine. > * If I configure no SnmpEngineId in the property file I get > an exception (See debug output below) > * If I configure a wrong SnmpEngineId in the property file I get > an endless loop with response of variable > snmpProxyDrops (1.3.6.1.6.3.11.2.1.2.0) > (See debug output below) > > ************************************************ > runapplication.sh get_next > Util(): Using properties file 'get_next.properties'. > Starting discovery Engine ID ... > > TimeWindow.setSnmpEngineId(): host slsrx9, port 4702, snmpEngineId > 8000137005736C73727839125E > > TimeWindow.setTimeLine(): snmpEngineId 8000137005736C73727839125E, node > uk.co.westhawk.snmp.stack.TimeWindowNode[engineId=8000137005736C73727839125E, > engineBoots=3, engineTime=86369, latestReceivedEngineTime=86369] > (Complex) pass to key takes 1.718 > uk.co.westhawk.snmp.stack.DecodingException: User MD5 does support > authentication, but received message without authentication: > 1.3.6.1.6.3.11.2.1.2.0: 78 > at > uk.co.westhawk.snmp.stack.AsnDecoder.processSNMPv3(AsnDecoder.java:400) > at > uk.co.westhawk.snmp.stack.SnmpContextv3.ProcessIncomingMessage(SnmpContextv3.java:645) > at > uk.co.westhawk.snmp.stack.AbstractSnmpContext.run(AbstractSnmpContext.java:495) > at java.lang.Thread.run(Thread.java:536) > PduException: User MD5 does support authentication, but received message > without authentication: 1.3.6.1.6.3.11.2.1.2.0: 78 > > ************************************************** > slsmgr: >runapplication.sh get_next > > Util(): Using properties file 'get_next.properties'. > Starting discovery Engine ID ... > > TimeWindow.setSnmpEngineId(): host slsrx9, port 4702, snmpEngineId > 8000137005736C73727839125E > > TimeWindow.setTimeLine(): snmpEngineId 8000137005736C73727839125E, node > uk.co.westhawk.snmp.stack.TimeWindowNode[engineId=8000137005736C73727839125E, > engineBoots=3, engineTime=92119, latestReceivedEngineTime=92119] > (Complex) pass to key takes 1.26 > 1.3.6.1.2.1.11.32.0: 2883 > 1.3.6.1.2.1.11.32.0: 2884 > 1.3.6.1.2.1.11.32.0: 2885 > 1.3.6.1.2.1.11.32.0: 2886 > 1.3.6.1.2.1.11.32.0: 2887 > 1.3.6.1.2.1.11.32.0: 2888 > 1.3.6.1.2.1.11.32.0: 2889 > 1.3.6.1.2.1.11.32.0: 2890 > ... > ********************************************************* > > I see both times at the debug output that the correct snmpEngineId is > discovered from the agent.

I'm trying to create a trapd service for collecting my company's traps. Most of the apps out there, like OpenNMS, do not support de-duplication of traps, which is something I definitely need. -So my plan was to first get something where I'm collecting the traps and decoding them. -Once they are decoded, then I want to somehow run them against the MIBs to make them more readable. -Then deal with the other stuff, like how to de-duplicate, how/where to store, probably need threading, etc. I'm not great at reading javadocs. I'm following the documentation and trying to use the examples. I have the TrapReceive working but it doesn't decode anything. The documentation says to create a context and then: Pdu trapPdu = context.processIncomingTrap(byte[ ] message) I was trying to make this a part of the following else in TrapReceive: else { int version = evt.getVersion(); String host = evt.getHostAddress(); System.out.println("ReceiveTrap.trapReceived():" + " received undecoded trap v " + version + " from host " + host); } Quite frankly I'm not sure how to do it. So far I've been unsuccesful trying to use the examples and javadocs. I tried creating the context by adding this: SnmpContextBasisFace context = trapPdu.getContext(); But I don't see how or where to use this one (from the documentation) for getting the info out of the trap: trapPdu = context.processIncomingTrap(byte[ ] message); I'm also having trouble with the Util class. Whenever I try to use it like: private Util util; the compiler says it can't find it. I have Util.java compiled and in the classpath. Any help is appreciated.

SnmpContextBasisFace tmpcont = new SnmpContext(host,context.getPort(), context.getTypeSocket()); byte[] mess = evt.getMessage(); // and get it to decode the thing. Pdu got = tmpcont.processIncomingTrap(mess); System.out.println( "got unexpected trap from "+host+" :"+got.toString()); tmpcont.destroy(); } catch (Exception x) { x.printStackTrace(); } } so what you need to do is : 1) create a temp context that matches the trap you have. 2) extract the data from the event 3) get the context to decode it 4) dispose of the context. - If you know that the traps will come from a smallish set of hosts you could improve this by using a contextpool. > > Quite frankly I'm not sure how to do it.

I was figuring I would have to write a seperate program to process the MIBs using libsmi (I think). This would have to create some type of config or rules file for each MIB. Then, when I start TrapReceiver it would pre-process all these new rules/config files. Then I would have some method to run the event past these rules and translate if it finds it. I assume this will be my hardest task.

Similarly you need to pass the -classpath to javac to compile. If you are building in an IDE like netbeans you usually need to mount the jar so the IDE knows to give it to javac when it is called.

I have a few questions. Is there a suggested way to get the data out of the pdu, like the enterprise OID? Generic Trap, Specific Trap, etc? Or should I just convert to a string and tokenize it? Similarly: How can I check the size of a varbind[]? How can I pull out the data for each varbind so I can make a comparison? What are timeticks? I ran into an interesting problem. I had one trap come in and got an context exception because public was in upper case "PUBLIC". Any way to deal with that kind of scenerio?

The way the stack works is that it checks all parameters of the incoming trap with the parameters of the Context. The default community name of the SnmpContext is "public". When your trap comes in with a different community name (and "PUBLIC" is different to "public"), it cannot decode it. The stack does not offer anything more flexible. Strictly speaking, the community name is the only piece of security SNMPv1 has got, albeit a very weak one. You should know what community name to expect. If possible, configure your managers to send traps with "public".

The Util classes are defined in the example packages so you could import it from there. The Util classes are in: * uk.co.westhawk.examplev1.Util * uk.co.westhawk.examplev2c.Util * uk.co.westhawk.examplev3.Util * uk.co.westhawk.test.Util None of these are compiled by default so importing them will fail. Your best option is to copy the code from the one that suits your needs into your own Util class in the same package as the stuff you are writing, you can then add any utilities specific to your needs to it.

Yep, we have set the maximum packet size to a relatvively conservative value (1300 bytes) See the doc on public void setMaxRecvSize(int no) in AbstractSnmpContext Although UDP datagrams can be fragmented (fragmentation is part of the network layer (IP), not the transport layer (UDP/TCP)), some firewalls reject incoming fragments. Therefor it is best not to setmaxRecvSize higher than the largest packet size you can get through your network topology. In a mixed network I'd advise you to reduce the request so that the reply fits, especially since the setMaxRecvSize doesn't work correctly in ContextPools. > > Comments or suggestions anyone? > > Damian Coutts Tim.

I'm guessing the problem here is that the javadoc for getSpeed is confusing in that the value is only valid when you have previously called public long getSpeed(InterfaceGetNextPdu old) The thing is that you need 2 pdu's some time apart to calculate the speed as the MIB only gives you the the number of bytes, so you need 2 samples some time apart. (By the way you kindly sent us fix for this by email, but I couldn't see any changes in the file! Could you either tell me what you changed or diffs? ) Thanks. Tim.

Not much real difference, except that if you code with waitForSelf you will need to make fewer changes when you need to move to an async style using beans or Observers. We generally find that in the early phase of a project it is nice to use a blocking style, but pretty soon you need to move to async for speed (and modularity). > > Thanks, > zeev Tim.

Essentially I implemented getIfSpeed which returned the speed rather than the throughput. I have realised now that trying to get use InterfaceGetNextPdu was probably not the right approach for what I am trying to do anyway. The Javadoc is a little confusing.

It is my first time in this list. First, I would like to congrat all the guys from the development: the stack is very good! Second, I would like to report the newest application using your stack in the market: we are a brazilian telecom company and we are starting to use your stack to develop a network management application for managing our products. Well the question is the following: I noticed an exception in my code where a calling to the BlockPdu.getResponseVariableBindings() method returns a null and does not throws anything. If I am not mistaken, the Pdu was of type GET_NEXT. I cant see any situation in that a get response can return a null varbind without any error. Do you know if it may happen? If yes, in what s
