Hi All,
I'm a newbie of Netdisco and haven't use Netdisco V1, therefore i have no
experience at all. I follow the recommendation and started with Netdisco V2.
Netdisco is a powerful tool, and I'm happy with the result it provide us with,
but I have one issue.
I don't get information from a HP Procurve Stack switch with a Master and five
slaves in a stack. I can probe the Master without no problem, and I use
snmpwalk to receive info from slaves now using the community flag in snmpwalk
public@stackslave1. I found no information how to get this working for Netdisco
2. I notice a mib netdisco-mibs/hp/hpswitchstack.mib that may help solve this?
Thanks in advance!
-Fredrik

Hello,
I was not aware of that constraint on hostnames,
thank you for pointing out the relevant RFCs.
Anyway I've found that the source problem lies within
NetAddr::IP:Lite and I've already asked the package
maintainers if they are willing to apply an easy fix
given that every other GNU software I've dealt with
has no problem with hostnames containing underscore
character. So hopefully it will be fixed upstream.
In the meantime I locally patched NetAddr::IP::Lite
module but I'm having hard times figuring out how
to force a module rebuilding, do you have any tips?
Attached you will find the patch I'm using.
thank you
regards
P.S.
I tried to subscribe to nedisco-user ml two days ago
but I'm still waiting for list admin approval, what is
missing?

Hi Francesco,
I don't think there's any "problem" to fix here other than you
accidentally not having RFC-compliant host names.
Rather than put effort into patching all the world's software to deal
with this, wouldn't it be better to rename your hosts to use "-" instead
of "_", to follow the agreed standard?
regards,
oliver.

The Internet standards (Request for Comments [1]) for protocols
mandate that component hostname labels may contain only the ASCII
[2] letters 'a' through 'z' (in a case-insensitive manner), the
digits '0' through '9', and the hyphen [3] ('-'). The original
specification of hostnames in RFC 952 [4], mandated that labels
could not start with a digit or with a hyphen, and must not end with
a hyphen. However, a subsequent specification (RFC 1123 [5])
permitted hostname labels to start with digits. No other symbols,
punctuation characters, or white space are permitted.

SUBJECT: [Netdisco] Error when discovering by DNS name
Hello,
performing manual discovery by using DNS names
sometimes does not work depending on the hostname.
If the hostname contains an underscore ("_" character)
then I get the following error:
~$ bin/netdisco-do discover -d test_router.example.com [8]
[19106] info @0.000011> discover: started at Mon Jun 9 14:01:58
2014
[19106] info @0.000418> discover: finished at Mon Jun 9
14:01:58 2014
[19106] info @0.000580> discover: status error: error running
job: Can't call method "addr" on an undefined value at
/home/netdisco/perl5/lib/perl5/App/Netdisco/Daemon/Worker/Poller/Device.pm
line 50.
If the hostname does not contain an underscore character
then the discovery is successfull:
~$ bin/netdisco-do discover -d test.example.com [9]
[19140] info @0.000013> discover: started at Mon Jun 9 14:16:30
2014
[19140] info @6.384684> discover: finished at Mon Jun 9
14:16:36 2014
[19140] info @6.384977> discover: status done: Ended discover for
123.123.123.123
Discovering the same host using its IP address is ok.
Do you have any idea?
thank you
regards
