Version 4.10: 06/09/2001 This is version 4.10 of the simple Java SNMPv1, SNMPv2c and SNMPv3 stack. It can be collected via our homepage: (1.3 Mb) Read the file StackUsage.html for general information how to use the stack. The stack still uses JDK 1.1.X . The javadoc is generated with JDK 1.2. The changes in this release are almost all bug fixes. The most important change is that of AsnUnsInteger; using type long (instead of type int). This does probably mean that you have to recompile and change your code where it concerns TimeTick, Counter (i.e. Counter32) and Gauge from type int to type long. We would like to thank Visionael Corp (http://www.visionael.com) for their support. We would like to thank everyone that was kind enough to send us bug fixes and useful suggestions: - Donnie Love (dlove@idsonline.com) - Jin Huang (jhuang@infiniswitch.com) - Julien Conan (jconan@protego.net) - Ken Swanson (gks@navcomm1.dnrc.bell-labs.com) - Maga Hegde (mhegde@zumanetworks.com) - Steven Bolton (sbolton@cereva.com) Sorry if we've left anyone out. ****** CHANGES **** ** Changes (mostly bug fixes) in package uk.co.westhawk.snmp.stack: - AsnObject: moved all the constants to interface SnmpConstants - AsnObject: improved converting bytes to length in getLengthPacket() - AsnObjectId: the class is now represented as an array of type long (instead of type int) - AsnInteger: improved converting bytes into int in bytesToInteger() - AsnUnsInteger: using type long (instead of type int). int is too small for all Counter32 values. - AsnUnsInteger: improved converting bytes into unsigned int in bytesToLong() - AsnUnsInteger***: improved converting bytes into unsigned int in bytesToLong() - AsnOctets: when the value is an empty, it no longer causes a ArrayOutOfBoundsIndexException in toIpAddress() and in toHex() - AsnOctets: added the method toDisplayString() - Pdu: retry_intervals is no longer static - Pdu: changed what error status is set in fillin() in case of a decoding problem, see getErrorStatus() - TrapPduv1: because of AsnUnsInteger, timeticks is now a type long as well - AsnEncoder.EncodeTrap1Pdu(): the IPAddress in a TrapPduv1 is now being correctly encoded as an IPADDRESS type (and no longer as the default TIMETICKS type) - TrapPduv2: fixed a bug so now the trap pdu will get filled in properly when being decoded ** Changes in package uk.co.westhawk.snmp.pdu: - BlockPdu: added method getErrorIndex() ** Changes in package org.bouncycastle.crypto.*: - Using version 1.08 (instead of 1.05) of the Bouncy Castle crypto API ** Overall changes: - because of AsnUnsInteger, some variables are now of type long as well (instead of type int) - changed some typos (whilest -> whilst) *** NEW - interface uk.co.westhawk.snmp.stack.SnmpConstants Version 4.8 27/04/2001 We would like to thank Visionael Corp (http://www.visionael.com) for their support. ****** CHANGES **** - org/bouncycastle/crypto - Updated bouncycastle version to 105 - catch exception in pdu.fillin that can happen when agent makes an error in encoding the varbind list Version 4.7: 13/04/2001 We would like to thank West Consulting BV (http://www.west.nl), Adherent Systems Ltd (http://www.adherent.com) and Visionael Corp (http://www.visionael.com) for their support. ****** NEW **** ** Privacy to SNMPv3 The stack now supports SNMPv3 privacy.

For authentication the MD5 and SHA1 protocols can be used. ** Exceptions: - PduException - AgentException (extend PduException) - DecodingException (extend PduException) - EncodingException (extend PduException) ** Classes: - We have implemented AsnUnsInteger***. We have not tested this though, since I couldn't access any MIB who implemented that. - We have implemented GetBulkPdu. - We have implemented BlockPdu that performs a sends a request and blocks until it receives a response. ** Packages: - uk.co.westhawk.snmp.util - uk.co.westhawk.snmp.net - uk.co.westhawk.appletv3 ** The Context structure: - New interface SnmpContextFace and SnmpContextv3Face - New class AbstractSnmpContext implements SnmpContextFace - New class SnmpContextPool that shares SnmpContext objects - New class SnmpContextv3 extends AbstractSnmpContext - New class SnmpContextv3Pool that shares SnmpContextv3 objects ** SNMPv2c We have implemented SNMPv2c. It does not (yet) contain traps. ** Packages: - uk.co.westhawk.appletv2c ** The Context structure: - New class SnmpContextv2c extends SnmpContext - New class SnmpContextv2cPool that shares SnmpContextv3 objects ****** CHANGES **** 1. The community name has moved from Pdu to SnmpContext. Instead of using: Pdu pdu; pdu.send(community); use: SnmpContext context; Pdu pdu; context.setCommunity(community); pdu.send(); Almost all Pdu constructors with the community name in it have been removed. 2. Other Pdu methods have changed: - send() may throw a PduException. - added method getResponseVarbinds() throws PduException - added method getRequestVarbinds() - The Pdu constructor uses SnmpContextFace (see above). 3. - Changed class SnmpContext so it extends AbstractSnmpContext (instead of Object) 4. - Changed debug setup. See AsnObject.setDebug(). 5. - Besides the mandatory SNMPv3 objects (like COUNTER***), added NSAP_ADDRESS, UINTEGER32 to AsnObject. 6. - Added AsnObject.getRespType(). 7. - AsnOctets.toString() will prefix any hexidecimal number with '0x'. - AsnOctets.toString() has improved the test to see if the Octet is printable. - AsnOctets will handle an OPAQUE type as well. 8. - Pdu.getErrorStatusString() will return 'timed out' instead of 'general error' when the request has timed out. Version 3.3: 10/02/2000 - Manchester (UK), Westhawk Ltd. We have fixed some thread problems in the pdu package. Tim Panton (snmp@westhawk.co.uk) Birgit Arkesteijn (snmp@westhawk.co.uk) Version 3.0: 01/07/1999 - Manchester (UK), Westhawk Ltd. We have moved to the UK, note our change of email address and webpages. The setup of the classes has changed; - package names contain our company domain uk.co.westhawk.applet1_0 uk.co.westhawk.applet1_1 uk.co.westhawk.servlet uk.co.westhawk.snmp.beans (NEW) uk.co.westhawk.visual (NEW) uk.co.westhawk.snmp.pdu uk.co.westhawk.snmp.stack Some methods names has changed to match the JDK 1.1 convention. No backwards compatibility is provided! The documentation (in javadoc format) has been improved. ***** uk.co.westhawk.snmp.beans (JDK1.1) NEW The package uk.co.westhawk.snmp.beans contains beans that can be used in any Java Builder. It is written to ease the use of our SNMP stack. They are simple enough to serve as example to write your own beans. The (toplevel) bean SNMPBean contains some general information, that is worthwhile reading. Some Windows NT specific beans have been written, using the NT vendor MIB. There is an Ascend Router bean and an IBM Network Computer bean. ***** uk.co.westhawk.visual (JDK1.1) NEW The package uk.co.westhawk.visual contains a graph that can be used to represent numerical data. The graph can draw the 10log() representation or the normal representation. ***** uk.co.westhawk.snmp.stack (JDK1.1) Not much has changed since the previous version. Documentation has been added. Some classes and methods have been restricted to access by this class only. Some method names have changed to match the JDK 1.1 style. ***** uk.co.westhawk.snmp.pdu (JDK1.1) Not much has changed since the previous version. Documentation has been added. Some classes and methods have been restricted to access by this class only. Some method names have changed to match the JDK 1.1 style. We have added the Pdu: - OneGetPdu This class is added to be consists with the other classes, like OneSetPdu, OneGetNextPdu. ***** uk.co.westhawk.servlet (JDK1.1) We have added a servlet: - ReachHostServlet This servlet returns a HTML form that can be used to find out if a host can be reached on a certain port. The servlet Interfaces contains some general information, that is worthwhile reading. ***** uk.co.westhawk.applet1.0 (JDK1.0) These applets show how to use the pdu's and the servlets. Documentation is improved. ***** uk.co.westhawk.applet1.1 (JDK1.1) Every aspect of our SNMP stack can be found in one of the applets. These applets show how to use the pdus, the beans, the graph. The documentation is improved. The html files may contain our (test) configuration, so you may have change that to your own. Some applets can be used as applications as well. We have added an applet for every bean that is written: - testAscendActiveSessionBean - testDialogChannelStatusBean - testInterfaceBean - testNTPrintQBean - testNTServiceNamesBean - testNTSharedResBean - testNTUserNamesBean - testNcdPerfDataBean (contains the graph as well) We have added an applet that used the SetPdu request: - set_one ***** How to use the stack The stack can be used in various ways, this makes it flexible on one hand, but confusing on the other hand. The easiest way to use the stack, is to use one of the beans from the uk.co.westhawk.snmp.beans package. There should be enough documentation in the code to help you. The beans form a bridge between the uk.co.westhawk.snmp.pdu (and uk.co.westhawk.snmp.stack) package any applet or application you may want to write. Our bean gathers specific MIB information, i.e. the OID (Object Identifier) is hard coded. The beans should be easy enough to understand, and with little effort you can write a bean for your own purpose. You can use, of course, the Pdu's from the uk.co.westhawk.snmp.pdu package directly, which offers you more flexibility. Our beans and applets will show you how, although this will require some basic knowledge of SNMP. We also provide you with a couple of servlets. The benefits of servlets are described in the package documentation. Servlets can be combined with (simple) HTML or with an applet on the client side. For more background on SNMP we recommend: - The Simple Book by Marshall T. Rose (Prentice Hall, 1994). - SNMP, SNMPv2 and RMON by William Stallings (Addison-Wesley, 1996). Tim Panton (snmp@westhawk.co.uk) Birgit Arkesteijn (snmp@westhawk.co.uk) Version 2.0: 21/08/97 In this version two stacks have been joined: - Version 1.1 of West Consulting BV (see ) - Our version Alpha2 of the stack (see ) The setup of the classes has changed; - package snmp has been split into snmp.pdu snmp.stack ***** snmp.stack (JDK1.1) The package snmp.stack contains only those classes that are necessary to send/receive SNMP requests. For that purpose the classes: - GetNextPdu - SetPdu have been made abstract so they are consistent with the Pdu class. See snmp.pdu package for non-abstract versions. The thread communication between Pdu, SnmpContext and Transmitter is improved. ***** snmp.pdu (JDK1.1) All Pdu's that did not belong strictly to the stack have been moved to the package snmp.pdu. We have added some Pdu's: - OneGetNextPdu - OneSetPdu These should be used instead of the old GetNextPdu and SetPdu. GetNextPdu and SetPdu are made abstract like Pdu to be more consistent. - GetNextPdu_vec - SetPdu_vec These Pdu are the vector versions of OneGetNextPdu and OneSetPdu. They request/set a vector of variables instead of one. - InterfaceGetNextPdu This class does a GetNext on the interfaces (ifTable) of a host. It can be used to loop over all interfaces in the ifTable. See for that purpose * the servlet Interfaces or * the applet1.1 getAllInterfaces ***** servlet (JDK1.1) We have added a servlet: - Interfaces This servlet loops at a regular interval over all interfaces of a certains host. The HOST, PORT and INTERVAL should be configured in the JavaServer. The applet1.0 getAllInterfaces is written to communicate with this servlet. ***** applet1.0 (JDK1.0) The applets are split up into the ones written with JDK1.0 and with JDK1.1 This is done because at this time there are hardly any 1.1 Browsers. The applet: - getAllInterfaces This a very thin applet. It displays all the interface usage (bandwidth) of a particular host. It gets its information of a servlet (configurable), the so-called 3-tier setup. The host is configured in the servlet. ***** applet1.1 (JDK1.1) The applets are split up into the ones written with JDK1.0 and with JDK1.1 This is done because at this time there are hardly no 1.1 Browsers. The applet: - getAllInterfaces is the applet version of the servlet Interfaces. There is no display like applet1.0, just printing. Tim Panton (snmp@westhawk.nl) Birgit Arkesteijn (snmp@westhawk.nl) Version 1.1: 30/10/96 Note the additional copyright, I changed jobs. Second version of stack. Changes are: Bug in ASNInteger fixed. Smarter use of threads, separate Transmitter class which is re-useable. Application specific PDUs: InterfacePdu : stats on an interface UpSincePdu : gives the date that the agent started. Sync mode for PDUs, you can send a PDU and then block waiting for an answer by calling Pdu.waitForSelf(), returns a boolean indicating if an answer was recieved. More demo programs: get_one : an applet which repeatedly gets a single ASNInteger (sysUptime is good) and displays thread activity. Interface : an applet that shows the speed of an interface as calcuated from two sucessive measurements. Interfaces : an applet that shows the state of all (if they fit) the interfaces on an agent. JeevesUpSince : a servlet (for use in the Jeeves web server (SUN)) that displays the date a host was rebooted. JeevesInterfaces: a servlet that displays the status of the interfaces on an agent. (The demo directory contains some examples for use with the Jigsaw webserver (from W3C) ) Note that the Interfaces demos assume that the interfaces are contiguous and numbered from one. Livingstone Portmasters don't do this. The applets can all be seen by running the html file of the same name, the default hostname won't work, so you will have to edit them. To use the Jeeves and Jigsaw demos you will have to install the server of your choice and then add this directory to the server's classpath. Start the server and then follow the instructions for adding servlets. The status of the stack is unchanged, it is still a work-in-progress, and certainly not a robust commercial product. The code's none to clean either. I'll try to keep releasing new versions and putting them on www.westhawk.co.uk tpanton@ibm.net Version 1.0: 11/03/96 This is a simple SNMP Version 1 stack. Background. It was written to learn Java and to see if it could be done. The target application is _small_ applets that indicate the state of a system. For example the throughput of a router or the battery power remaining of a UPS. It is not intended to be used in a general purpose network management station. It has no MIB browsing capabilities, you have to know the OID of what you want to monitor. There are _many_ other packages that do MIB browsing and general network management. I wanted something lighter that I could just pop in a (netscape) frame and leave there all day. In practice this means that it will start to become inefficient once you have more than 10 or so active PDUs at a time, each PDU owns (is) a thread, and holds it for ~20 seconds after the request is sent, so if your update period is short or the number of PDUs is large then the number of threads will rise rapidly. Copyright. See the header of each file: Basically you can use it for whatever you want, but you can't blame us for anything wrong with it, and you can't rewrite history by removing our copyright text. Status. It is a work in progress, don't assume it is tested, or that it represents typical West quality, it was done as a prototype, and seemed to have some value of it's own so we set it free :-). Use. The idea is that for each class of problem you should subclass the abstract Pdu class. This design is based on the observation that most realworld numbers you want to extract from an SNMP agent are based on two or more values from the MIB. Throughput for example is caluculated from five numbers, so a throughput Pdu would request all five, calculate the single throughput percentage and then pass it back to whoever wanted to know. I include a trivial example - OneIntPdu which gets a single integer value from an Snmp agent. Once you have such a Pdu class - or are happy with OneInt then uage is simple, see get_one.java The steps you have to follow are : 1) create an SnmpContext , giving it the host name and port number of your SNMP agent (If this is run in an applet then you an only connect back to that server - but you can watch the throughput on that, which is what I use it for.) 2) create a PDU, passing it the SnmpContext, add the OIDs you are interested in with pdu.add_oid(oid). A better way would be to have the PDU constructor add what it needs, but OnIntPdu is too dumb. 3) add an observer with pdu.addObserver(this), the argument is the object that wishes to be notified when the new value arrives. It must implement Observer, that is it must have a public void update(Observable obs, Object ov) method. This method will get called when the value arrives. 4) call pdu.send("public"); Actually the community name should really belong with the context, but I have not got arround to fixing that. 5) sleep, or do something else, your updat ... ...
