Hello Netdisco Developers,
In the last few days, I've played around with the Netdisco 2 plugin system.
First of all I have to say that it's just nice to see how little is
necessary to get a plugin up and running - great work! Nevertheless I have
two questions:
- How will Netdisco 2 (or Dancer) every use a custom template path?
I don't get this. I tried to write a small plugin that uses its own
templates located in /opt/netdisco/dt, so I registered a custom template
path. In order to do this, I set my template path like this:
----
package App::Netdisco::Web::Plugin::DT;
use Dancer ':syntax';
use Dancer::Plugin::DBIC;
use Dancer::Plugin::Auth::Extensible;
use App::Netdisco::Web::Plugin;
use File::ShareDir 'dist_dir';
#register_template_path( dist_dir( 'dt' ));
register_template_path( '/opt/netdisco/dt' );
----
If my custom path is set to register_template_path( '/opt/netdisco/dt' ), I
can see that my path is added to the include path array
(Dancer::Template->engine->config->{INCLUDE_PATH}) (in
Dancer/Template/Abstract.pm, 'template'). But in the subroutine 'view'
(returns the actual view path), $views_dir is fetched from
Dancer::App->current->setting('views').
Dancer::App->current->setting('views') is a string and not a list that
contains '/opt/netdisco/perl5/lib/perl5/auto/share/dist/App-Netdisco/views'
only. So my template will never be found... Did I do something wrong?
- Does Netdisco or Dancer provide any way to 'auto-login' with a pre-shared
key?
I've written a very simple REST Webservice plugin that basically is a
'netdisco-do-webservice'. Now I wonder how to get authentication running.
The problem is that a potential rest client will not be able to login to
the website first. I worked around this problem by enabling X-REMOTE_USER
and setting the http header to 'X-REMOTE_USER: admin'. Is there maybe a
better way to do authentication in netdisco/dancer without patching the
Netdisco source code? It would be nice to have something like a
'shared-key' based auth ...
Another thing that came to my mind are custom-roles. Right now netdisco
only has a few pre-defined roles. Maybe it would be helpful if a plugin
could use its own roles. For example my webservice user could get a
'webservice' role, so the webservice would not be available to all the GUI
admins/users. But I fear this would most likely require a db-schema
extension, so this will not be possible any time soon, right?
Regards,
Daniel

I have recently started using/testing Netdisco 2 and I would like to ask:
1. Is there a way to get IP Address reports, similar to those available
in Netdisco 1.x ("Report IP Inventory")? This functionality is important
to us.
This is now my only remaining question (see below), so please let me
know whether such a report is or will be available in ND2.
When I issue commands (like "Discover All") from the web GUI, the jobs
seem to be queued forever (in the Job Queue page). Things work fine when
commands are issued from the CLI.
2. Why jobs are not run when issued from the web page, but stay queued?
How can we force the execution of these jobs?
3. Is there a way to perform full network auto discovery starting from
routers, i.e. can we provide the discovery starting points (routers) and
let ND2 to discover/macsuck all connected devices automatically? (If I
remember right -it's been long since I last did it-, this works in ND 1.)
I found that netdisco-daemon was not running, so these problems were
expected. Once I started it, everything worked fine.
Thanks for the great app.
Best regards,
Nick

There's an open tracker item to implement this, which effectively means
it's on the TODO list:
http://sourceforge.net/p/netdisco/netdisco2/50/
Other than that, I'll add that it's our intention to implement all
existing reports in Netdisco 2 :-)
On this topic Eric has done fantastic work so far, but there's still a
lot to do... see the word "report" featuring in our commit log:
http://sourceforge.net/p/netdisco/netdisco-ng/ci/6bb2e3819f3196798e56554e1a8f6ea224833cdf/log/?path=
Patches welcome!
regards,
oliver.

Thank you for the update.
We do hope you can move this forward!

I was wondering how we can adjust the refresh time for the Job Queue
page (on the ND2 Web GUI).
The problem is that it refreshes so often, that I can hardly even read
something on the page!
I have tried to find a setting to adjust the refresh time interval but I
haven't been able to locate an appropriate setting. "check_userlog"
should simply disable the refresh.
Please let me know how I can adjust it.
Thanks,
Nick

There's no user setting for this - the timer value is hard-coded. I'd
welcome a tracker item for this as a feature request! There's definitely
room for improvement on this page.

There's a small "pause" button in the top right of the display, in case
you didn't notice it.

Hi folks,
I figure that interest in LAN, WAN, data centre, a bit of Linux, and
coming from somewhere in Europe, might have some crossover with people
on this list. Please take a look at our vacancy and drop me a line if
you have any questions:
http://www.jobs.ac.uk/job/AHS124/network-analyst/
p.s. and yes, we do run Netdisco 2 in production :-)
regards,
oliver.

Hello,
I ran into a slight problem when using the 'domain_suffix' parameter:
Clicking a device in the network map results in a 'no such device' error
(That's the same error as documented in the bugtracker
http://sourceforge.net/p/netdisco/netdisco2/48/) . Attached to this mail is
a patch that should fix this issue.
regards
Daniel
