RC2 and Java
by arajgarh＠iwu.edu 29 Jul '05

29 Jul '05

I installed RC2 on Fedora Core 4 today, installed perfectly using the RHEL4 guide. However, I have this problem in the getDeviceData.log for each IP Device that it queries : java.lang.NoClassDefFoundError: snmp/SNMPException at QueryNetbox.run(QueryNetbox.java:703) So I'm not collecting any data. Do you think the problem is Java 1.5 ? I have the snmp jar placed in the jre/lib/ext directory. IF Java 1.5 is a known bug then I will downgrade.

Release-notice: NAV 3.0 RC2
by morten.vold＠ntnu.no 25 Jul '05

25 Jul '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 NAV 3.0 RC2 is now available for download at http://metanav.ntnu.no/ . A number of small, but critical bugs were found in RC1, and have been fixed in this new release candidate. Unless critical bugs are reported in this release candidate, this will be the baseline for NAV 3.0.0. Upgrading from beta RC1 ======================= Some OIDs have been added, and due to a fix in the OID-tester, we strongly recommend you to re-run the SQL script doc/sql/snmpoid.sql, as documented in the README file of the same directory. CHANGES ======= Version 3.0_rc2 (released 20 July 2005) Improvements: * More data for the snmpoid table, please run the new snmpoid.sql to ensure your system will work after an upgrade. * The Service Monitor's RPC plugin no longer complains loudly to stderr. * The Messages and Report web interfaces will no longer intermittently cross-over mysteriously. * The alert message texts have been updated to contain messages for all known alerts. * Overlapping time periods in an alert profile will no longer cause double alerts to be sent. * Modules that are down can now actually be found and deleted in the Device Management interface. * The Traffic Map system and Network Explorer can now be properly configured to run without a single NAV root directory. * Alert Profiles web pages now include the correct stylesheets, so it won't look as funny. * Several getDeviceData-related problems were ironed out. * The menu on Messages' maintenance list is no longer ugly. * IP devices put on maintenance will now be taken off maintenance, instead of remaining on maintenance forever. * Maintenance-scheduled IP devices can now be properly deleted from messages. * Next/previous page-links in reports will now work properly even when using advanced search options. Also, advanced searching on database fields that contain underscores (like sw_ver) will now work. * Performance improvements in the IP Device Center. - -- Morten Vold NTNU ITEA Integrasjonsgruppen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFC3j+FXxIl0kpcOkQRAuL/AJ4mRZDumeyw6J5WYEbu2fMElly8rACg06qD JiE2e+s7Ioaa/iHjoby5vEY= =C+7R -----END PGP SIGNATURE----- >From kreide at gmail.com Wed Jul 20 14:06:25 2005 From: kreide at gmail.com (Kristian Eide) Date: Wed Jul 20 22:06:30 2005 Subject: [Nav-users] Tomcat java (class/module) missing error & vlanPlot java error In-Reply-To: <42DE04B3.5050506(a)ntnu.no> References: <E04174B5A513E542AD2CB6C1E18D9C7D4DD55C(a)Exchange.admin.khio.no> <200507191831.06408.kreide(a)gmail.com> <42DE04B3.5050506(a)ntnu.no> Message-ID: <b4c110fd05072013061cfba430(a)mail.gmail.com> > > You need to copy (or symlink) the .jar files from nav/lib/java to the > > shared/lib tomcat directory. > That shouldn't really be necessary if you've already symlinked those > jar-files to $JAVA_HOME/jre/lib/ext/ ?

I think the recommended procedure is to only put the SNMP and Postgre jars in lib/ext and leave all NAV-specific jars in nav/lib/java. It is then necessary to symlink these files into the shared/lib tomcat directory. Of course symlinking everything into lib/ext works and is simpler :) > > Should we perhaps have a tomcat install guide which mentions this? > If anything were to be put in such a guide, it would be a bit about > whether or not it is necessary to restart Tomcat or delete the extracted > webapp directories when the NAV webapps have been upgraded.

Bug in Add IP device?
by Ketil.Forselv＠hin.no 23 Jul '05

23 Jul '05

Try to run the following command: Switch(config)#snmp-server chassis-id XXXXXXXXX where XXXXXXXXXX is the "System serial number:" for the switch which you obtain with sh ver. You must manually add this value to all switches in Cat 2900-series.

Error adding particular switch
by arajgarh＠iwu.edu 15 Jul '05

15 Jul '05

Below are the errors in the logs. The other logs don't have errors. One noticeable bug is that I can only add two instances of the "Cisco Catalyst 6000 MSFC2" with SysObjectID=1.3.6.1.4.1.9.1.301 If I delete those two I can add two other of those, but can never add more than two. This is not a problem with other switches. Trying to add a third gives me an error: Mod_python error: "PythonHandler editdb" Traceback (most recent call last): File "/usr/lib/python2.3/site-packages/mod_python/apache.py", line 299, in HandlerDispatch result = object(req) File "/usr/local/nav/apache/webroot/editdb/editdb.py", line 156, in handler output = editPage(req,pageList[table](),request,unicodeError) File "/usr/local/nav/apache/webroot/editdb/editdb.py", line 463, in editPage outputForm,action) File "/usr/local/nav/apache/webroot/editdb/editdb.py", line 2435, in add disabled=True)) TypeError: __init__() takes at least 2 non-keyword arguments (1 given) ------------------ eventEngine.log: Jul 15 06:41:16 2005 eventEngine EVENTQ_MONITOR_TASK-3-RUN SQLException when fetching from eventq: Operation requires a scrollable ResultSet, but this ResultSet is FORWARD_ONLY. ------------------ networkDiscovery-stderr.log: SQLException: Operation requires a scrollable ResultSet, but this ResultSet is FORWARD_ONLY. org.postgresql.util.PSQLException: Operation requires a scrollable ResultSet, but this ResultSet is FORWARD_ONLY. at org.postgresql.jdbc2.AbstractJdbc2ResultSet.checkScrollable(AbstractJdbc 2ResultSet.java:179) at org.postgresql.jdbc2.AbstractJdbc2ResultSet.beforeFirst(AbstractJdbc2Res ultSet.java:251) at networkDiscovery.avledVlan(networkDiscovery.java:1113) at networkDiscovery.main(networkDiscovery.java:93) ------------------ getDeviceData-stderr.log has a lot of similar errors, this is the last: SQLException for update statement: INSERT INTO swport (swportid,moduleid,ifindex,speed) VALUES ('441','32','63','1000') org.postgresql.util.PSQLException: This statement has been closed. at org.postgresql.jdbc2.AbstractJdbc2Statement.checkClosed(AbstractJdbc2Sta tement.java:2304) at org.postgresql.jdbc2.AbstractJdbc2Statement.getUpdateCount(AbstractJdbc2 Statement.java:432) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeUpdate(AbstractJdbc2S tatement.java:268) at no.ntnu.nav.Database.Database.update(Database.java:999) at no.ntnu.nav.Database.Database.insert(Database.java:923) at no.ntnu.nav.getDeviceData.dataplugins.Swport.SwportHandler.handleData(Sw portHandler.java:239) at DataContainersImpl.callDataHandlers(DataContainersImpl.java:64) at QueryNetbox.run(QueryNetbox.java:791) ---------------- Aditya Rajgarhia 305 Kemp Hall x2042 arajgarh(a)iwu.edu >From kreide at gmail.com Fri Jul 15 11:22:36 2005 From: kreide at gmail.com (Kristian Eide) Date: Fri Jul 15 19:22:46 2005 Subject: [Nav-users] Error adding particular switch In-Reply-To: <7113539.1121446237565.JavaMail.arajgarh(a)iwu.edu> References: <7113539.1121446237565.JavaMail.arajgarh(a)iwu.edu> Message-ID: <b4c110fd0507151022207f8eb2(a)mail.gmail.com> > when fetching from eventq: Operation requires a scrollable ResultSet, > but this ResultSet is FORWARD_ONLY.

Regarding previous message

> * createConnection ClassNotFoundExecption error: org.postgresql.Driver* > Note that I have installed the jdbc package, however ROOT cannot use it > even though all other users including navwrite can use it. I tested > using a java file that uses jdbc. What this error means is that the PostgreSQL JDBC driver is not available at the time getDeviceData is run. It is supposed to use the 'navcron' user, so either make sure the JDBC driver is somewhere on the classpath or put (or symlink) the jar file in your jre/lib/ext directory. -- Kristian

Box being polled for tempInlet
by lars.hakedal＠usit.uio.no 12 Jul '05

12 Jul '05

We have a cat356048G which gets 'cricket-configed' to have a tempInlet, but Cricket complains with 11-Jul-2005 15:30:05*] Received SNMP response with error code noSuchName. OID: 1.3.6.1.4.1.9.9.13.1.3.1.3.1 every five minutes. >From what I understand, getdevicedata asks the box for known OIDs which are then added to the cricket-config if the oid exist? Here is what I believe is the relevant entries from the GetDeviceData.log: Jul 06 13:45:17 2005 uio-gw9-l0_00 OID_TESTER-6-DO_TEST Starting test for netbox: uio-gw9-l0 (cat356048G(30)), snmpoid: tempInlet Jul 06 13:45:17 2005 uio-gw9-l0_00 OID_TESTER-6-DO_TEST Got results from uio-gw9-l0, length: 1 (reqGetnext: true, vl: ) Jul 06 13:45:17 2005 uio-gw9-l0_00 OID_TESTER-6-DO_TEST Match: null, val: 1 snmpget'ing the oid from the box also fails. As short term solution I've removed tempInlet from the database DELETE FROM snmpoid WHERE oidkey='tempInlet'; and removed and added the box. -- Lars H?kedal larsha(a)usit.uio.no

This might be a guess, but try editing the file /usr/local/nav/lib/python/nav/web/__init__.py Now cut out the line "import nav.web.auth" and paste it again inside "def headerparserhandler" right above the line "import state". Make sure the lines are all indented the same way. ie: def headerparserhandler(req): (..) import nav.web.auth import state from mod_python import apache Please tell us if this fixed the problem. -- Stian S?iland ITEA systemdrift, NTNU - det skapende universitet orakel(a)ntnu.no Tlf: 735 91500 =/\=
