I think it's actually

$(hostname -s).$(hostname -d)

with

hostname -f

as a fallback if one of those is empty.

oooooooh

hostname -d is empty

(not sure why yet) so it again should fall back to hostname -f

Or, to put it differently, the default is what DNS says. Local settings, like

hostnamectl set-hostname

are used as a fallback if DNS is not providing an answer.

I'll do some research why these two nodes seem to be failing that dns check (the whole lab estate has certname in the wrong place, so that's interesting)

is OS the same?

thank you for that though, I'll correct the real problem, but clearly these 2 nodes have something a bit odd on the DNS

OS on the test hosts is RHEL 9 or Debian 11, they are all working apart from 2 Debian 11 nodes

I'll sort that out once I fix the puppet.conf user error

check PTR records maybe?

the actual DNS resolution is working 100% fine, already checked that, it's something about these 2 nodes local setup when they resolve themselves from the hostname command (hostname -d is empty on these 2, despite being able to resolve them with the fqdn)

checking /etc/hostname and /etc/hosts is also worth a shot

great suggestion

and than you for fixing my user error

some dns libs read those, others don't. because of that: always cert certname

found it

what silly problem

127.0.1.1 maps to hostname

no idea why on these 2 nodes

set that to hostname.fqdn and it works

🙂

I recommend purging those with puppet.

that's Debian's thing 🙂

Actually, I was wrong about

hostname -f

. It's

$(hostname -s).$(hostname -d)

or just

hostname -s

if domain is empty: https://github.com/puppetlabs/puppet/blob/7.25.0/lib/puppet/settings.rb#L69-L78

useful education, thank you

hostname_fact is probably derived from

hostname -f

?

it gotta be used somewhere 🙂

I'm stuck on a logic. I want to iterate over elements in an array and add one element after another to a new variable and for sake of simplicity print it out each step at a time. For example:

$path = '/my/path/is/here'
$array = split($path, '/')
$blub = ''
$array.each |$i| {
 $blub = "$blub/$i"
 notice($blub)
}

This is obviously the wrong syntax but I hope it's getting my point across.
