Dear all,

I have installed Network Administration Visualized 3.3.0 on Debian Etch. I have installed NAV through aptitude. I'm very impressed with the amount of work and thought that have gone into this software package.

However, i do have several problems.

I can not see any informastion in the section called "Port View" when i click on a device in Home > Report > Devices in Operation

Could this be some snmpproblem? I installed net-snmp and could do a snmpwalk against the device.

Also serveral devices report Availability like this one: Availability -4.1e+180% -5.1e+175% -3.8e+166% (day / week / month)

Could this be snmpversion troubles?

When i try click on the Traffic Map, all i get is a new page showing a java aplet that just show the java logo. I have tried this with both firefox and IE. The only way to exit is to kill the browser process.

Could this be a java version problem.

getDeviceData.log is zero size. /var/log/nav/getDeviceData/getDeviceData-stdout.log is also zero.

In /var/log/nav/getDeviceData/getDeviceData-stderr.log contains:

java.lang.NullPointerException at snmp.SNMPSequence.setValue(Unknown Source) at snmp.SNMPVariablePair.<init>(Unknown Source) at snmp.SNMPv1CommunicationInterface.getNextMIBEntry(Unknown Source) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAllJavaSnmp(SimpleSnmp.java:665) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:640) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:616) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:598) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:522) at OidTester.doTest(OidTester.java:115) at OidTester.oidTest(OidTester.java:44) at QueryNetbox.run(QueryNetbox.java:724) java.lang.NullPointerException at snmp.SNMPSequence.setValue(Unknown Source) at snmp.SNMPVariablePair.<init>(Unknown Source) at snmp.SNMPv1CommunicationInterface.getMIBEntry(Unknown Source) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAllJavaSnmp(SimpleSnmp.java:690) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:640) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:616) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getNext(SimpleSnmp.java:303) at no.ntnu.nav.getDeviceData.deviceplugins.MibIISw.MibIISw.processMibII(MibIISw.java:308) at no.ntnu.nav.getDeviceData.deviceplugins.MibIISw.MibIISw.handleDevice(MibIISw.java:144) at QueryNetbox.run(QueryNetbox.java:787)

Could this be related to the missing port view section?

Thank you for your help. Any suggestions would be most welcome!

Regards, Rikard

Hi Morten;

I'm still having the same issue.

The output of "invoke-rc.d tomcat5.5 status" is

"Tomcat servlet engine is running with Java pid /var/lib/tomcat5.5/temp/tomcat5.5.pd"

The only changes I've made are those specified in: "/usr/share/doc/nav/README.Debian"

Thank you for taking the time to address this problem.

Regards, Nestor

When attempting selecting the Network Explorer I get the following:

This is a packaged installation of NAV 3.2.2. on a Debian Etch 4.0.

Hi Nestor,

Either your Tomcat servlet container is not running, or it is listening to the wrong port (which I doubt, unless you've changed your Tomcat config). Check the tomcat status using "invoke-rc.d tomcat5.5 status". If it's not running, you can start it using "invoke-rc.d tomcat5.5 start" (as root, of course).
