Thanks for the history digging !

Do you know when resolv.conf started appearing ?
I guess after TCP/IP got invented ?
The wikipedia page does not mention it.

<https://man.openbsd.org/resolv.conf> says it first appeared in 4.3BSD.
I can neither confirm nor deny this, but it does match my *belief* that
BSD did it first, and then System V copied it.  It's a bit before my time,
though.

Thanks for the hints !
I then dug a bit more, found a github which has the sources for very old 
BSDs !
https://github.com/dank101?tab=repositories

The README suggests (IMHO) that previous versions already had TCP/IP 
working.
In the 4.3BSD-Reno, there is no resolv.conf by default in /etc (but a 
namedb).
But I found a man page 
(https://github.com/dank101/4.3BSD-Reno/blob/master/share/doc/smm/11.named/resolv.conf).
Inside, there's a comment :

     @(#)resolv.conf	6.2 (Berkeley) 2/29/88

Funny, it's already the true and loved syntax we use today !
     domain Berkeley\fB.\fPEdu
     nameserver 128\fB.\fP32\fB.\fP0\fB.\fP4
     nameserver 128\fB.\fP32\fB.\fP0\fB.\fP10

(I just don't know what the gibberish chars mean, I guess it's some 
TeX/groff syntax ?)

I'll dig more into the repositories and let you know ; )
(2BSD had none, but it only has source code, more later)

THIS was a fun rabbit hole to enter ^^

 From "https://en.wikipedia.org/wiki/History_of_Unix"

Perhaps the most important aspect of the BSD development effort was the 
addition of TCP/IP network code to the mainstream Unix kernel.
[...] The network code found in these releases is the ancestor of much 
TCP/IP network code in use today, including code that was *later* 
released in AT&T System V UNIX.

So your belief was right. BSD before SysV !

"http://gunkies.org/wiki/4BSD"
     4 BSD does *NOT* include any TCP/IP networking

"http://gunkies.org/wiki/4.2_BSD"
     4.2 BSD follows the betas of 4.1a & 4.1b. 4.2 BSD Is special 
because it incorporates the first versions of BSD TCP/IP

Let's see. I downloaded the source code of 4.2 and 4.3BSD from The Unix 
Heritage Society (https://www.tuhs.org/Archive/Distributions/UCB/)

------
$ grep -R "resolv.conf"

4.3BSD/lib/libc/net/res_init.c:char    *conffile = "/etc/resolv.conf";
4.3BSD/lib/libc/net/res_init.c:                        printf("MAXNS 
reached, reading resolv.conf\n");
4.3BSD/etc/named/tools/ns.lookup/man/nslookup.l:(Default = value in 
/etc/resolv.conf, abbreviation = do)
4.3BSD/etc/named/tools/ns.lookup/man/nslookup.l:/etc/resolv.conf	initial 
domain name and name server addresses.
------

So it's not in 4.2, and appeared in 4.3.

Fun one "https://github.com/dank101/4.2BSD/blob/master/include/netdb.h" :

/*
  * Assumption here is that a network number
  * fits in 32 bits -- probably a poor one.
  */

Ok, out of the hole now ^^

That is an insult. I bailed out of fedora 15 years ago, tired to being 
an always sick lab rat for redhat. Ubuntu which linuxcnc used for one 
release wasn't a tasty piece of cake, and when linuxcnc jumped to debian 
at about jessie, it was a whole new ball game. And with bookworm, 
linuxcnc is scheduled to join the debian repos. Generally speaking, 
keeping things up to date has become so routine its boring.

Not possible. Michael and I have known each other since the '80's when 
he was a starving college student. I'll just let it go at that.

That is flat untrue.

Because you answer what you want, I'll re-ask :
"Why can't you follow others advice, hell, if you don't trust us, even
the perfectly correct and up-to-date manpages ?"

?! First, who's Michael, second, even if it's your friend, you won't
fill a bug because of that ?
What if it's really a bug, and other people have the same one ?

If you don't know who Mike Sweet is, why are you hassling me?  There's 
25 years of history to computing before Linus released his his linux, 
Michael and I were both there in the trs-80 color computer days and 
while Mike was take college classes and releasing code for the color 
computers in the mid 80's, it was sort of a contest among the coco users 
running os-9 on our coco's, to see who who find and fix the bugs in code 
he released. os-9 was unix that ran on a 8 bit machine with a 65k max 
memory.

Keeping networking working on linux has been an art, not a science.
looking at one of my buster machines. /etc/network/interfaces has this:
====
# The primary network interface
allow-hotplug eno1
iface eno1 inet static
	address 192.168.71.10/24
	gateway 192.168.71.1
	# dns-* options are implemented by the resolvconf package, if installed
	dns-nameservers 192.168.71.1
	dns-search coyote.den
====
And it Just Works. But that was way the hell and gone too easy, so it 
just had to be changed, so that stuff no longer works for bullseye. 
There is nothing in /etc/network/interfaces.d
So let me snoop, here cuz that entry does not exist on this bullseye 
machine. Looking to see what did make it work, brb.
I can't recall which debian, but at one time I had to put it in the last 
stanza of /etc/dhcp/dhclient.conf but I see that's not been touched, 
here or on a buster machine..
/etc/nsswitch.conf looks default.

So ATM I have no clue what I did because I've forgotten whatever I did 
to make it work for bullseye, lost in the noise from doing 23 damned 
installs before someone suggested I unplug all usb, but my key board and 
mouse are wireless, so I left those buttons plugged it and did yet 
another install and this one worked. I've since rebuilt my usb tree as 
it reaches like a weeping willow to nearly every inch of the real estate 
here.  All that re-install BS caused by the installer silently finding a 
couple usb-serial adaptors and ASSUMING I was blind and using brltty and 
orca. Has any of you ever tried to use a computer whose keyboard 
response was delayed by nearly 2 seconds per keystroke because its 
looking for a 1200 baud tty that isn't there, and then yells the 
keystroke at you in some idea of a computer voice.  Spend 2 weeks trying 
to use a computer like that, and you'll have a new appreciation for my 
level of frustration.

It should have asked me if I wanted that crap but did not.

You have all claimed I missed it or told it to install that, but 23 
damned times? I'm sure its here someplace because all 24 times I filled 
in the network details manually and was equally amazed when I still had 
a network on the after install reboot. That FWIW, was a first.

Everything works except printer sharing and I can't ask cups, my posts 
to the cups list are apparently routed to /dev/null, so I come here for 
help and all this dirty laundry gets drug out again. And again. And 
again. While the question I asked is very carefully ignored. Unreal.

Cheers, Gene Heskett.

The last two lines of that file are configuration elements for the
resolvconf package.  They only take effect if resolvconf is installed.

Most likely, your bullseye system simply doesn't have resolvconf.

This is discussed at
<https://wiki.debian.org/resolv.conf#Configuring_openresolv_or_resolvconf>.

The comment right before them also tells you which package you need for
those lines to work.

Your experience led me to fixing someone else's problem on IRC.
They were trying to install Debian for linuxcnc (but on an amd64 machine)
and had the same problem because they'd left a serial lead plugged in so
got brltty and orca.

I advised them to reinstall to fix things but this time to undo the serial
lead until the install was over. That worked fine for them and they were
very happy. (It's the simple fix that I think I suggested that to you three
times in the course and was ignored.)

If you're deafblind and using a Braille reader - it looks for a serial tty.
That's the only way it can work. It can't ask you first necessarily.

There are a bunch of cups manpages: there are lots of documents online.
The people recommending you avahi/bonjour/zeroconf are recommending it
because it works - for them and for 99.9% of people. Your system: your
rules - but it doesn't always help us help you to solve the problems.

There are reasons why we ask folk - in general on this list and in the FAQ
- to provide information, to copy/paste log entries or what they're seeing
on screen. We can't sit on your shoulder and watch what you've typed: we're
all relying on guesswork much of the time.

Possibly you did, but I didn't glom the usb connection because it came

That is a huge if. Probably less than 1% of the folks who only fit in 
one box or the other. It could have loaded orca and spoke to me, but 
didn't, it could have asked me on screen and didn't.  What it did was 
make an ass out me in everyone elses mind. Yeah, these days I'm an old 
fart with the poor short term memory that goes with 88 years on the wet 
ram. But I was carving code for an rca 1802 chip before most of the 
readers here were born, doing it by looking up the memonic, and entering 
the corresponding hex code in a quest super elf's hex monitor, code so 
useful in 1979 that it was still in daily use at KRCR-tv when the 
station burnt to the ground in the later 90's, well after Mt St Helens 
blew its top. As a retired television Chief (& usually only, I'm a CET 
too) Engineer, that 16 or so years might as well be a couple of eons, 
the tech, even in never twice same color days, the tech moved a heck of 
a lot faster than that.

My wife of 31 years passed a couple years back and I should throw my 
poles in the boat and go fishing. But I've been diabetic for nearly 40 
years & the water is too cold for my feet, so for S&G's I'm building a 
3d printer farm instead.

You betcha. Which gets my posts the TL;DR treatment just because I do

For future readers : this is plain wrong.
This is a perfect example of "assuming without knowing".
It's a bit like saying "TCP/IP was invented for the DARPA, and I'm a 
pacifist, so screw it" (note it's only a metaphor).

A simple web search is enough to understand what a *protocol* is, and
what those particular protocols/software suites are, and are for.
Approximation : it's like an automatic enhanced DHCP protocol.

As Andrew says, it works for 99.9% of the users, and is recommended to
people who :
- don't know how to configure things, or
- don't want to configure manually, or
- don't care how things work

But of course, and contrary to my metaphor about TCP/IP, 
avahi/bonjour/zeroconf is NOT required when you know what you are doing 
and/or you
follow usual best practices.
It's an helper protocol, not a required one.
And as every protocol, you are tied to how the vendors implement them.

Since new class of users has been identified, namely those who have 
serial port adapters, but no brltty, perhaps, a new screen should be 
added to the installer:

Assistive technologies have been enabled because serial port adapter has 
been detected, so Braille terminal may be connected.

(*) Continue assuming presence of brltty.
( ) Disable assistive technologies and proceed as regular installation.

Because you answer what you want, I'll re-ask :
"Why can't you follow others advice, hell, if you don't trust us, even
the perfectly correct and up-to-date manpages ?"

I don't need to know who he is. Now I know, thanks, but it changes nothing.
And if Sweet is REALLY your friend, why not asking him ?

Computer history started WAY before that.

Debatable. The Debian way is one of the easiest.
But funny, only happens to you, among the zillions Debian-based installs.
Still can't see the problem ?

One of the best advice I've learnt from experienced sysadmins is :
"always take notes of what you're doing".
The other one being "RTFM".

Really ?! Who exactly is ignoring what ?!

Again, FOR THE FOURTH TIME :
"Why can't you follow others advice, hell, if you don't trust us, even
the perfectly correct and up-to-date manpages ?"

Others have warned me. I tried despite their warnings ...
I get to the same point as them : it's pointless to try to help
someone who does NOT follow advices.
I guess I'm done here.

I guess it's overdue to point out again what should be obvious: You don't
have to run NetworkManager to make use of DHCP or anything else. So you
don't need to have your name resolution config overwritten. And you can
remain under the Debian umbrella.

I will go even further: NetworkManager is for laptops, not home setups. We
don't use it on servers in a data center, period end. It has no use-case in
that environment.

Evidence on that bo that something has been there, and put a # in front

Hello,

On Mon, Apr 10, 2023 at 12:05:06PM -0400, gene heskett wrote:

Just for the benefit of any inexperienced people who may read this
in future:

- As pointed out already, Gene's resolv.conf file contains obvious
  syntax errors.

- Gene has been told this many times by many people over the course
  of many years.

- Gene refuses to acknowledge or correct this, nor to stop advising
  other people to copy him.

- How anything Just Works for Gene is a matter of luck, not design.
  Frequently things *don't* Just Work for Gene, and then these
  habits frustrate any attempt to help him. The chances are good
  that in any given situation he will ignore all advice and just
  repost the same problem again in a few weeks, months or years.

- Gene's behaviour does not restrict itself to resolv.conf. A great
  portion of the advice Gene offers on this list is factually
  incorrect.

It would be best to corroborate anything Gene advises you to do with
the documentation and other posters. Sometimes he is correct, but
too many times he is not.

Cheers,
Andy
