      Hello !

Mod_python error: "PythonHandler mod_python.publisher"
Traceback (most recent call last):

You have to make a file called .htaccess, eg :
echo "SetHandler none" > .htaccess
This should be in a FAQ, very easy to forget. :-)

Creating .htaccess in "public_html" solved the problem.
Thanks!

Subject: [Nav-users] Use SNMP::Info to manage device types?
Message-ID: s2316158.051@gwmta2.weber.edu
The developer list is closed, so I am would like ask a question to this
list.
I believe there is a way to manually add device types to NAV, and there
is a Wiki page listing many device OIDs.  This works, but it may be a
duplication of effort.
There is a perl module named SNMP::Info that provides an
object-oriented interface to Network Devices and data stored in SNMP
MIBs.
http://snmp-info.sourceforge.net/
If this module could be integrated into NAV, many different network
management projects can add devices to this module, and all will benefit
from it.
Any thoughts on this?

In my opinion main NAV problem is, that it is not flexible, there is no 
interface for adding custom devices. I was writing about this, but there is 
no feedback.
Tristan's idea is very good.

The SNMP::Info module is probably cool, but as the SNMP handling in NAV is
written in java, it doesn't help us much. 

You can add support for device foo in NAV by writing a device handler in
getDeviceData subsystem, which shouldn't be too difficult, I suggest using
one of the existing handlers as a starting point.

Best regards,

I don't know enough details about the NAV database, but I would assume
that alternative methods for harvesting SNMP data for insertion into
the NAV database would be possible. Wouldn't it?

List of devices supported by SNMP::Info:
 http://snmp-info.sourceforge.net/DeviceMatrix.html

BTW, people taking interest in the SNMP::Info package should also be
aware of the netdisco application (http://netdisco.org) for which
SNMP::Info was created.

netdisco is an application similar to NAV in many respects. It is
implemented solely in perl, has auto-discovery capabilities, has a
full-fledged API for extensions, the main interface is web-based but a
command line interface is provided as well. A nifty functionality is
layer 2 traceroute which displays switch port details along one
possible route between two IP adresses. netdisco also provides a
'Duplex Mismatch Finder'.

The web interface in netdisco is more basic, nowhere near as slick as
NAV, but I guess some ideas from netdisco could be incorporated into
NAV.

Keep getting these messages in getDeviceData.log:

GWPORTPREFIX Gwportprefix: gwip=128.39.xxx.xxx hsrp=false

SQLException: ERROR: insert or update on table "gwportprefix" violates

Does anyone know of a way to fix this, or doesn't it have any particular 
effect on NAV3 (beta 10)?

In fact, NAV is meant to be very flexible! New OIDs can be added via the web 
interface, and NAV will automatically detect which devices support the new 
OIDs.

Data collection is done by the 'getDeviceData' daemon, which uses a 
plugin-based architecture. The API for this is resonably well documented in 
Javadoc, however, it is a fact that familiarity with Java programming is 
required in order to create new collection plugins. Unfortunately it also 
seems many system administrators are much more familiar with script languages 
and the barrier to entry is thus high.

Creating a perl binding which focused on easy of development would solve this 
problem, but it is of now uncertain if resources are available to implement 
something like this. We will discuss it internally and announce any decision 
this list.
