They can always read the man pages, as other have pointed
out to me. That also means it was not "Hacked".

Here you go:

I set

  DNS=192.168.255.10:53

And got:

# systemctl restart systemd-resolved.service

# resolvectl
Global
 Protocols: LLMNR=resolve -mDNS -DNSOverTLS DNSSEC=no/unsupported
  resolv.conf mode: stub
Current DNS Server: 192.168.255.10
   DNS Servers: 192.168.255.10

Link 2 (eno2)
Current Scopes: DNS LLMNR/IPv4
 Protocols: +DefaultRoute +LLMNR -mDNS -DNSOverTLS 
DNSSEC=no/unsupported

Current DNS Server: 127.0.0.1
   DNS Servers: 127.0.0.1

Link 3 (eno1)
Current Scopes: none
 Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS 
DNSSEC=no/unsupported

Link 4 (br0)
Current Scopes: none
 Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS 
DNSSEC=no/unsupported

Link 5 (virbr0)
Current Scopes: none
 Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS 
DNSSEC=no/unsupported

Global's and eno2's DNS server are different.  So
broken.  I will wait.And 127.0.0.53 refused to
consistently talk to my caching DNS server.
Something else to fix. Until then, your advice
is not so good.

I did fix it.  My system is working wonderfully now.
And as I stated before, you can find what I did in
the man page.

As other have pointed out on this thread, breaking

And I ONLY want one DNS.

Now you have a system that won't do things that most fedora systems do out of 
the box.  You've got a system that might pull in systemd-resolved at some point 
in the future if a dependency of some other package updates, and break your 
setup. You have a system that can't support split DNS, so if you end up doing

Sorry, I've not run windows much so I'm not familiar with how it fails.  

However, that seems like a broad brush to paint the issue though. Just because 
something didn't work exactly like you expected (and it works just fine for 
most every one else) doesn't really make it like windows. If anything, the 
problem was only exacerbated by your attempts to fix it. 

As for the childish nicknames, I hope I get to be Scrooge McDuck, but I'm most 
likely to be Goofy.

Yes, you removed the package that would modify the contents of the file the 
symlink pointed to.  Your real solution was to remove the package.  Renaming a 
symlink does nothing.

But you're basically setting up an unmaintainable mess, something

I appreciate you not using vulgar language, but you are talking about Disney 
characters out of the blue, and I can only assume you're calling *ME* and my 
fellow Fedora users bad names.

This whole thread is full of nonsense.

If you install f37 from scratch, you have to install

to get NetworkManager to pay any attention to the old

to move all the ifcfg files to "keyfiles".

I did break down and do the migrate and it seemed to work. I didn't

Yeah, if you just edit /etc/resolv.conf without reading it (leaving it a
symlink to /run), your edits will get lost.  All you have to do is
remove the symlink and replace it with a file, and systemd-resolved will
stop touching it (again, as documented in the file).  It's not some
mystery, or difficult problem to solve, if you read the comments and
referenced documentation.


It is all a bit of a maze, and I don't really see how this was an
improvement on the previous methodology.


A single system-wide resolv.conf cannot handle more complicated setups,
such as a VPN where lookups for certain domains should be sent to a
server across the VPN.  You have to run some form of local DNS server to
handle that (which could be BIND, Unbound, dnsmasq, etc.).  Each of
those have their own configuration quirks that can make it more
complicated to programmatically manage, so systemd-resolved was created.


I have open vpn installed.  It communicates through a network bridge and 
the old ifcfg files.


I have not used it in a while, as open vpn for Windows
is corked on Windows 10 and 11.  I gave up on it.
I did a bug report on it, but they never fixed it.



I'm not entirely satisfied with systemd-resolved, but it solves things
for a majority of cases.


Likewise with network configuration.  If the previous config files
actually did the job, why didn't they keep on using them, and just
update the tools that set them up?


The previous ifcfg files had many quirks, starting from being created as
shell variable lists to feed to bash scripts for network config.  They
were also specific to Red Hat Linux derived OSes (e.g. Fedora, RHEL,
CentOS, etc.).  NetworkManager was created to solve multiple things, one
of which was standardizing network configuration across distributions.

The NM plugin to support the RHL-style ifcfg files has been there as a
backwards-compatibility wedge, but it was time to move on from using
that by default (and deprecate the old network-scripts pile of shell
code).


Maybe some day when I have a ton of time to waste,
I will try to get the official way to work.

Yeah, if you just edit /etc/resolv.conf without reading it (leaving it a
symlink to /run), your edits will get lost.  All you have to do is
remove the symlink and replace it with a file, and systemd-resolved will
stop touching it (again, as documented in the file).  It's not some
mystery, or difficult problem to solve, if you read the comments and
referenced documentation.

A single system-wide resolv.conf cannot handle more complicated setups,
such as a VPN where lookups for certain domains should be sent to a
server across the VPN.  You have to run some form of local DNS server to
handle that (which could be BIND, Unbound, dnsmasq, etc.).  Each of
those have their own configuration quirks that can make it more
complicated to programmatically manage, so systemd-resolved was created.

I'm not entirely satisfied with systemd-resolved, but it solves things
for a majority of cases.

The previous ifcfg files had many quirks, starting from being created as
shell variable lists to feed to bash scripts for network config.  They
were also specific to Red Hat Linux derived OSes (e.g. Fedora, RHEL,
CentOS, etc.).  NetworkManager was created to solve multiple things, one
of which was standardizing network configuration across distributions.

The NM plugin to support the RHL-style ifcfg files has been there as a
backwards-compatibility wedge, but it was time to move on from using
that by default (and deprecate the old network-scripts pile of shell
code).

I waited one release cycle to try it in the hopes that
any possible bugs might be resolved by then. Worked OK for
me.

There's your new hostname, fubar-a-go-go...  ;-)

But being serious, I did start looking through the man files for the
new networking schemes (man systemd-resolved).  And supposedly,
/etc/resolv.conf is a link to /run/systemd/resolve/stub-resolv.conf
And when it is, it controls the file its linked to.

If you unlink the file, and edit your /etc/resolv.conf, systemd-
resolved should leave it alone, and you could could manually adjust it.
Of course, something else could, now, edit /etc/resolv.conf.

The DNS server data that comes from the DHCP daemon ends up in
/run/systemd/resolve/resolv.conf (note the different filename), and
systemd-resolved is using that information in conjunction with what it
provides to the traditional /etc/resolve.conf file.

It is all a bit of a maze, and I don't really see how this was an
improvement on the previous methodology.

Likewise with network configuration.  If the previous config files
actually did the job, why didn't they keep on using them, and just
update the tools that set them up?

NB:  My Fedora 36 installation works as it came out of the box, so to
speak.  DHCPD on my CentOS server is configuring the network as
I expect.  The F36 does go through its own DNS maze, but is making use
of my BIND DNS server on CentOS.  And mDNS does work for the three
other things on my LAN that make use of it.  But I'm not using VPNs, or
multi-port networking cards.

But I'd say, start by looking at man systemd-resolved and noodling your
way through the things it mentions in there.

You renamed a symlink. It’s not really a solution, and unless you disable or 
remove systemd-resolved (and/or NetworkManager) it will be returned. 

And it is extremely childish behavior calling it Mickey Mouse.  Making fun of 
something you don’t understand is not a good way to learn how the world works.

I'm not sure how that's a good example.

If you are using systemd-resolved, then /etc/resolv.conf should simply have "nameserver 127.0.0.53"

It puts it there and things ago foo bar

for the nameserver. This is where the OS looks for name lookups when doing DNS lookups.
Then systemd-resolved will have whatever different DNS servers, defined per interface
along with which search paths that should be searched, as well as priority. That way you
can have all your internal names go to one interface that's on the internal network, a
certain name go to the virtual machine interface so it can manage DNS for local VMs
(which libvirtd supports), your work domain goes to your VPN interface, and the rest go
to your external interface for default resolution. If you're running bind, then you
would just need to set the the IP for your installation as the default name server. For
all of this, /etc/resolv.conf should remain using "nameserver 127.0.0.53".

Those ifcfg files aren't even supported in a fresh install
of fedora these days. As attempting to avoid NetworkManager
is a hopeless task, I converted all my ifcfg files to keyfiles
and it seemed to work OK.

https://fedoramagazine.org/converting-networkmanager-from-ifcfg-to-keyfiles/

It took a long time to define all my network stuff correctly,
and I found I could only do it with the nmcli command because
the GUI provided is utterly useless. It leaves buttons I want to
push disabled, and won't tell you why they are disabled.

Why don't you post the proper terminology?

I don't know about "those" people, but one server of mine has 12

resolv.conf on that one with no problems because of some issue with

You saw how it fell apart when it put different

did not match resolv.conf?  And how I kept
over riding my manual configurations.

This hurt me more than a Windows upgrade.
I use Linux to avoid that kind of nonsense.

If you do the config differently (ie the old way, and if dns is not

Re: Tip: how to make your own resolv.conf

2022-12-18 Thread Roger Heflin

>From what I can tell they developers expect everyone to do the config in
exactly one way.

If you do the config differently (ie the old way, and if dns is not
configured/defined I assume from dhcp and/or directly in the  Network
manager config), then the software rewrites the file with a valid entry in
it, to have no entry.

Developers seem to ignore backward compatibility and/or supporting how
something has been configured since before they were born.

I do not know what FC37 did.

By the way, I have two network cards.

The Internet facing was using dhclient to get
an IP from my router's dhcp server.  I have now
switched it to fixed IP.

My other network card has a DHCP server connected
to an internal DDNS server on it to to service
the comptuers on the internal side of the network.

Both cards are connected through iptables.

What ever helpful tools FC37 installed or updated
did not realize the comlexitiy of the network
and made things a nightmare for me.

2022-12-17 Thread Roger Heflin

You have to love developers erroring out on boot because they cannot update
resolv.conf.

I have written enough code to evaluate errors and report minor errors and
not give up.   If you give up on all errors the system is not going to be
very robust.

That may work on Fedora, but the last time I tried it on Ubuntu, the system
refused to boot past trying to initialize the network :-(.

I tried that.  I does not work on a link.

I threw that on the source file it links to.
Micky and Friends found a way around it.

Micky and Friends was a new feature of
FC37.  FC36 worked fine

Not when you don't have networkmangler installed. All my current Fedora

Not good enough. In the /etc/NetworkManager/NetworkManager.conf

Otherwise a DHCP lease renewal will replace resolv.conf yet again.



Good luck with that!

The file that DHCP lease renewal alters is not
/etc/names.conf, but /run/NetworkManager/resolv.conf.
Named.conf is a link to it.

So in my tip, what see is /etc/named.conf.000 getting
updated.

Micky and friends can't find my stuff!  Raspberries!!!

Maybe when Fedora fixes Micky and Friends, I
will alter it back.
