Hi Marco,
The "netdisco-deploy" script will upgrade the ND1 database to support
ND2.
So you can either make your new Netdisco 2 system point at the old
database, or dump and restore it to a new database.
Then run the "netdisco-deploy" as shown in the installation
instructions.
regards,
oliver.

hello
i'm looking for best practice to migrate version and host.
i have a running netdisco 1 on a Debian Squeeze (~3 years up &

In response to..
DBIx::Class::Storage::DBI::_select_args(): The rows attribute must be
a positive integer if present at
/home/netdisco/perl5/lib/perl5/App/Netdisco/JobQueue/PostgreSQL.pm
line 41
we made a small (and dirty?) fix. Downgrading DBIx did not work for
us...
It seems that the original code implicitly typecasts $num_slots to
something not an integer (a boolean?)
in the call to search(), the patch below prevents this typecast by
removing the logical OR operator from
the argument list of search() as well as the assignment in the
beginning
of the function.
We initially tried to keep the original return () if defined...
statement and checking $num_slots
for a non-integer value. And if that matched, set it to 1 (integer).
However this resulted in a new
error message.

line 110
'}, 'DBIx::Class::Exception' )
Running into this we changed the return () if defined... row to
return
if $num_slots is undefined or has an integer
value less than one. The statement ( $num_slots < 1 ) seems to catch
cases where $num_slot is not a
valid argument for the search function.
The patch below seems to be working for us running with Debian Wheezy
and App::Netdisco 2.029012.
Feedback on this would be very welcome.

Hi!
We have worked at an improved version of the IOS-XR arpnip script
with more exact checks on ip's and mac's.
It would be nice if this version could replace the one currently
being distributed.

Hi Jonas,
If you want, you could patch your installed version of Netdisco.
Or else, I suggest you take a look at upgrading to Netdisco 2:
https://metacpan.org/pod/App::Netdisco
regards,
oliver.

SUBJECT: [Netdisco] Wrong MAC Address
Good day,
I am having difficulties while getting the MAC Address of an ORing
Switch (IES-3162GC). The MAC Address is 00:1E:94:01:38:FE but the
SNMP
call only returns 0:1E:94:01:38:FE (First zero missing).
Netdisco is probably having troubles with this notation, here is the
error mail that I receive:
DBD::Pg::db do failed: FEHLER: ungültige Eingabesyntax für Typ

Is there a quick way to fix this?
Mit freundlichen Grüßen / Kind regards

You could try running a debug discover job, and looking for the

~netdisco/bin/netdisco-do discover -d 1.2.3.4 -DI

Would be nice for management to be able to grasp the whole network.
And kind of cool to print it out and put it on the wall.
No, but there's a port of our PNG graph code from Netdisco 1 (the image
will look different to netmap, but should be OK).
$ brew install graphviz <-- install graphviz on your system
$ ~netdisco/bin/localenv cpanm --notest Graph GraphViz
$ mkdir ~netdisco/graph
Copy the sample "graph" config from here into your deployment.yml file:
https://metacpan.org/source/OLIVER/App-Netdisco-2.029012/share/config.yml#L222
Run:
~netdisco/bin/netdisco-do graph
Then take a look in the ~netdisco/graph directory.
Good luck.

oliver.

Hi Nicolas.
I am working with Cisco 2960Xs myself today; setting up their SNMP config and
adding them to Netdisco v2.
Have you verified your Cisco configuration?
Here is an example of what I put in my Cisco switches, I have changed things
that should remain confidential:
snmp-server community MySNMPCommunity RO
snmp-server location Road Department - Basement Closet
snmp-server contact Kris Jacobs, JC x6813 [email protected]
snmp-server chassis-id WS-C2960X-24TS-L - MySerial#
snmp-server enable traps
snmp-server host x.x.x.213 MySNMPCommunity
snmp-server host x.x.x.228 MySNMPCommunity
THEN, if I want to verify that the switch is seeing inbound SNMP packets, I do
this on the switch's console/telnet session:
Debug snmp packets
Debug snmp requests
Term mon <-- this shows me the output of the debug capture in my telnet
session
Now that the switch is ready, go over to your command line on your netdisco
server and do this:
Netdisco-do discover -d <switch IP address>
If things are working correctly, you should see lots of scrolling SNMP-related
text in your telnet/console session on the Cisco switch.
Once you're done, turn off debugging & terminal monitor output on the switch
like this:
No debug all
Term no mon
Hope this helps!
-KJ

Hello,
I just setup Netdisco 2 today using the install instructions located here:
https://metacpan.org/pod/App::Netdisco#Installation
Extremely easy to do & it looks amazing... So, well done there guys & thanks
for all your work.
Netdisco is seeing all the Cisco switches without any issues, however, it's not
even detecting the Dell switches. I did a manual discovery & it will show the
switch, but again won't show anything connected.
I did some reading before because I had the same issue with version 1.x & it
was really difficult to try & figure out a solution. Only fragments of answers
& one of the filesets uploaded that was supposed to patch the dell MIB wasn't
available.
I saw there are the following mibs in ~/netdisco-mibs/dell/:
apollo.mib rldhcp.mib rlmng.mib rlssh.mib
dell_ita.mib rldnscl.mib rlphy.mib rlssl.mib
env_mib.mib rlfft.mib rlphysdescription.mib rlsyslog.mib
macbaseprio.mib rlfile.mib rlqosserv.mib rltuning.mib
mnginf.mib rlinterfaces.mib rlrmon.mib rludp.mib
qosclimib.mib rlip.mib rl_sensor.mib rlvlan.mib
rlaaa.mib rlipmulticast.mib rlsnmp.mib
rlapplication.mib rliprouter.mib rlsnmpv2.mib
rlcopy.mib rllcli.mib rlsntp.mib
I honestly haven't used SNMP extensively I have usually used an agented
monitoring system as I normally do system monitoring. So I apologize for any
time I'm wasting here with missing info or improper use...
The troublesome switches are Dell Powerconnects with most or all of the models
being the PowerConnect 6248.
Oh also, I'm running it on a Centos 6.6 i386 in a VM.
Thank you,
Keith
