heynnema and chili555 discuss netplan

heynnema

22:58

hello

@chili555 are you there?

chili555

Right here, my friend!

heynnema

how are u doing?

chili555

How are you doing this fine and luminous evening?

I am doing quite well!

heynnema

sheltered in place :-(

chili555

Even the docs and my wife agree!

heynnema

23:02

what do they say?

chili555

I wanted to discuss the netplan answer where you said to be careful about mv /etc/netplan/*.yaml

heynnema

ok

chili555

Because it might obliterate more than one yaml

However, that's what I intended!!!

heynnema

In so far, as some users have two or more .yaml files, and your mv command would rename them all to the same single name, thereby possibly wiping out files.

chili555

Because a person who installs server for the first time and doesn't know where to see why his ethernet isn't working...

is very unlikely to have two or more yamls with bonds and bridges and tuns and taps.

Those guys know what to do without poor, tired old Chili

heynnema

23:06

Let me give an example of my caution... hold a sec whilst I type...

chili555

New guys like the instant case most likely have one malformed file

...holding...

heynnema

A user has two files in /etc/netplan. One named eth0.yaml, and a second named wlan0.yaml. Your mv command would rename the first one to 01-netconf.yaml, and the file would get renamed to 01-netconf.yaml, so you'd lose all of the script in the first .yaml, due to the renaming.

chili555

Yes, indeed!!!

heynnema

and the second file would get renamed to the same 01-netconf.yaml

chili555

However, the guy with two files undoubtably created them himself and probably knows what he's doing.

heynnema

23:09

I didn't write that all correctly.

chili555

Those cases I treat very differently

heynnema

Let me try this again... but paying closer attention to my prose...

chili555

OK, but my reasoning is the same. Go ahead.

heynnema

eth0.yaml and wlan0.yaml. Your mv would rename eth0.yaml to 01-netcfg.yaml, and then immediately get overwritten by the wlan0.yaml rename, and you'd lose all of the script from eth0.yaml.

chili555

However, the guy with two files undoubtably created them himself and probably knows what he's doing.

Those cases I treat very differently

heynnema

23:12

But how do you know what .yaml files are in /etc/netplan to start?

chili555

You don't unless you ask: ls /etc/netplan

heynnema

correct

so how can you "blindly" rename them?

chili555

However, in a default server install, one file gets created that is a pretty accurate guess as to the ethernet interface and DHCP

Because a person who installs server for the first time and doesn't know where to see why his ethernet isn't working...

heynnema

Oh, but you assume that the user hasn't tried to "fix" their problem themselves, and not created what some other person told them to create in /etc/netplan?

we're all tired on old :-)

tired and old

I can't type this afternoon.

chili555

Based on what he posted, with no mention whatever of netplan or the good old, "I tried everything", it's a pretty safe bet.

He was wondering about ifconfig

heynnema

23:16

I never assume anything, and I would have done the ls /etc/netplan before the mv

chili555

net-tools, etc

heynnema

from xenial!

chili555

Yikes!

Crazy.

heynnema

unless I'm mixing up my cases today... somebody was installing xenial software on a 20.04 server!

chili555

I liked your comment to the other answerer that it was poorly done.

heynnema

23:18

refresh my tired and old memory...

chili555

Yes, that's the one. You down-voted him and he deleted

heynnema

yeah, that's the one.... my memory is still working! yeah!

chili555

You said:

Why would you install tools from xenial on 20.04 server? Of course lshw will show the ethernet as disabled. How do you know ens33? lo does not need an up. Incomplete and somewhat misleading answer. Sorry.

I thoght that was gold

heynnema

what a mouthful eh?

chili555

You spanked him!

heynnema

23:19

indeed! giggle

On a different note,

have you seen recent comments by Pilot6?

chili555

I am willing to try what I am 90% sure is the quick solution sometimes. This was a good one!

Yes. He seems a bit impatient these days. Cabin fever??

heynnema

yes, he's been down right rude and c.... I can't think of the word...

chili555

He seems to put in about 18 hours a day, too.

Maybe tired

heynnema

something

It's not like him.

or her :-)

chili555

If it continues or worsens, we might think about reaching out

heynnema

23:23

one user did in an answer. did u see it?

chili555

No. Do you have a link?

heynnema

It got deleted by the mods... and it would take some digging to find it again... but in short... the observer commented on Pilots tone and intent.... I'm saying it nicely.

chili555

Let's hope that the mods took note and are watching

heynnema

Darn it... I still can't think of the word... it starts with "c", and it means to talk down to somebody... help me...

condesending!

My memory still works... a little slow... but it still works!

chili555

exactly

heynnema

23:27

Old age is a cruel joke!

chili555

not a good attitude here, IMO

LOLOL!!! You talkin to me?

heynnema

enough about Pilot6... I was just curious if you saw it. No... I was talking about ME!

chili555

I suspect I have at least ten years on you!

heynnema

ok, I'll spring... how old?

chili555

Hint: I retired in 1998

heynnema

23:29

oh don't make me do the math...

chili555

Hint:I have a great-grandson!

heynnema

you could have retired young... giggle

chili555

I did, in fact

heynnema

I'm 65. I have brain surgery in 2018, and I still haven't gotten back to 100%

had brain

chili555

Hint: I am not required to take off my shoes at the airport

heynnema

23:31

oh I had some jokes to retort on that line :-)

chili555

LOL!

I have 12 years on you

heynnema

fess up

chili555

I had chemotherapy in 2009 and 2020.

heynnema

gosh... and just what are we both doing here on AU... we should be sailing or RVing!

chili555

I actually answered a post in the infusion chair!

heynnema

23:32

yuck

that's dedication

are u ok now?

chili555

I was chatting with a family on vacation in front of a restaurant in Silverton, Colorado and he asked about my RV

I told him my coach of choice was A380.

heynnema

A380 is a big one?

chili555

heynnema

yeah... that's a big one alright!

u let somebody else do the driving!

chili555

He didn't get it at first.

Yes, while I sip an adult beverage and get there is three hours, not three days!

heynnema

23:38

oh but you're missing the fun and the freedom of RVing!

chili555

Big payments, black water tank, parked 9 feet from partying drunks. Yeah, I know!

heynnema

giggle

do u have 8pm howlers near u?

chili555

I am not sure what that is so I expect not

Is that another term for partying drunks?

heynnema

Somebody started this thing... encouraging people to come outside at 8pm and howl. Idiots. Like little lambs they do what they're told, and act like Neanderthals.

chili555

Egad! No, mercifully, we don't.

heynnema

23:43

lucky you!

What city/state are u in?

chili555

Lake Wylie, South Carolina. Just outside Charlotte in the tax haven.

And you?

heynnema

Large covid activity there?

Lakeport, CA. 3 hours north of San Francisco

chili555

Nope. A few cases but we don't know anyone locally that had or has it.

Ahhh! One of the socialist states!

heynnema

Have you seen the john hopkins covid dashboard web site?

No... hippies, dopers, and naked people! Giggle.

chili555

not recently. I check the CDC site once in a while

heynnema

23:47

let me get the url for u...

gisanddata.maps.arcgis.com/apps/opsdashboard/index.html#/…

the data is shocking!

well done site

chili555

I just hope the downward trend continues.

heynnema

there hasn't been a downward trend yet!

China (if u believe the data) and Austria are flat-lined.

the number in the US are increasing daily

chili555

I believe precisely zero of anything China says. Zero.

heynnema

yup

chili555

cdc.gov/coronavirus/2019-ncov/cases-updates/cases-in-us.html

New Cases per Day seems to be declining.

heynnema

23:55

I'll review the CDC closer, later.

CDC site

Anyway, it's been a real thrill chatting w/you.

Keep up the good work my friend!

chili555

Likewise! Stay safe and let's all get through this without a cough or sneeze!

heynnema

take care!

chili555

Bye

heynnema

bye for now
