Facter does not deliver ip addresses

[Axel Bock]

Hi readers,

another problem of mine. A host which worked just fine on friday is now not able to find out its own IP address. The reason is pretty simple as far as I have figured out: Facter. Facter returns the network interfaces just fine: interfaces=eth0,eth1, but then the ipaddress_ETHx entries are completely missing.

Any idea what could be the cause of this?


Thanks in advance & greetings,
Axel.

Hi Axel - what OS? What version of Facter? What does the output of your 'ifconfig -a' (or local equivalent) look like? Could you please run 'facter --debug' and pastebin the output somewhere?

[Axel Bock]

Hello,

@Joseph: not yet.

@Eric: sure :) . SLES 11 SP2, and the output is here: http://pastebin.com/jqgNmewk

But I have an idea. I have another host where it still works. The host it stopped working on has two IP addresses configured on one (!) network device. so an "ip a" gives me:

[...]
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:50:56:99:05:02 brd ff:ff:ff:ff:ff:ff
    inet 130.250.8.15/24 brd 130.250.8.255 scope global eth0
    inet 130.250.8.20/24 brd 130.250.8.255 scope global secondary eth0
[...]

Maybe this is not actually covered by the detection algorithm of facter? :)


Anyway, thanks for your help!
Axel.

Hi,

How does your ifconfig -a output looks like?

Suspects:

I am going to guess this is the old 'There's no /sbin/ifconfig' thing.
I've got a pull request for facter that fixes this and a bunch of
other stuff at https://github.com/puppetlabs/facter/pull/267 if you
want to try checking out that version of Facter and trying it on your
SuSE box. It'll try and use /sbin/ip first and fallback on ifconfig
if that's not available. It might resolve this for you.

Hi Krysztof,

like this:

And @Ashley - no, there is an /sbin/ifconfig, as you can see ... isn't "Senderwarteschlangenlänge" a _great_ word? ;))

Greetings!
Axel.

[Axel Bock]

uuh ... /inet addr[...]/ as pattern in ip.rb? a wild guess ... if the output is localized - then puppet won't be able to get the IP address info, right?
check.

l1215022:~ # facter | grep _eth
l1215022:~ # export LC_ALL="en_US"
l1215022:~ # facter | grep _eth
ipaddress_eth0 => 130.250.8.15
macaddress_eth0 => 00:50:56:99:05:02
macaddress_eth1 => 00:50:56:99:18:02
netmask_eth0 => 255.255.255.0
l1215022:~ #

oh boy. seriously? NO ONE noticed that before?? I'm stunned right now.

[Axel Bock]

... @joseph: do you have localized ipconfig output?

(btw I have facter 1.5.2, puppet 2.6.17, both from suse rpms)

[Stephen Gran]

Hi,

Why do your init scripts start puppet with a locale other than C?

Cheers,

I have no idea what my init scripts are doing actually :) . I am just wondering why nothing shows up when *I* run puppet agent --test.
And it still confuses me that this seems to be a requirement (which I could not find anywhere ... not that I looked, though :) for a command line tool which usually runs in a localized environment.

hm.

Puppet, and Facter, usually force the environment locale to 'C' before
running external commands - precisely so that you don't have to worry
about this.

If you have found somewhere that doesn't do that, it is clearly and
unambiguously a bug, and you should file a ticket at
http://projects.puppetlabs.com/projects/facter/issues/new
