Good time of the day, people!
This time, accessing the web-interface I get the error:

Mod_python error: "PythonHeaderParserHandler nav.web"

Message-ID: 20060908114704.GB18951@nvg.ntnu.no

Hi

I have made some support for 3com vlan and port probing.
(Not everyone has thrown these out yet)

3Com patches and FreeBSD tips are available at: 
ftp://ftp.nvg.ntnu.no/pub/nav
_3com.java.patch
snmpoid.sql
QueryBoks.java.patch
The rest is some tips for FreeBSD GSW and related patches.

Some questions:

Has anyone "lost" SNMP data because drexelsnmp (javasnmp) did not give
the exceptions with v2c as it did with v1?
(At least it happened against net-snmp)

Is other equipment than Cisco (like FreeBSD with net-snmp) supposed
to be probed as Cisco?

Regards,
Roar Thron?s

Rajesh, did you ever figure this out?  UNINETT is about to launch
several Debian based servers for our customers, and these will be
running NAV.  When preparing installation procedures for these servers,
I've had the opportunity to actually install and test the Debian package
of NAV myself.

NAV is unfortunately picky about where it likes its Cricket to be
installed, something I hope we'll be fixing soon. I've followed the
README.Debian file, and I happened to overlook part of the installation
instructions.  With Cricket installed from source in /usr/local/cricket
as README.Debian suggests, I have the same problem as you do, and I've
found that the quickest solution to the problem is to do as the README
says and add the following symlink inside /usr/local/cricket:

  ln -s ./ cricket
