system installation – Proper way to install Ubuntu (Server 21.04) with PPPoE?

Recently I downloaded and burned ‘ubuntu-21.04-live-server-amd64.iso‘ to an USB-stick.
I need PPPoE connection while installing (as my router is in bridge mode).
https://www.debian.org/releases/jessie/amd64/apds05.html.en says to add (grub) boot-command-line-option ‘modules=ppp-udeb‘.
So I interrupted the boot-process pressing ‘e’ and made up this:

setparams 'Ubuntu Server'

  set gfxpayload=keep
  linux /casper/vmlinuz --- modules=ppp-udeb
  initrd /casper/initrd

At installation after keyboard-selection comes ‘detection of network hardware‘, where the interface is found and is selected to (IPv4) DHCP.
PPPoE configuration does not appear (and DHCP obviously fruitless).


So, what is the proper way to install Ubuntu (Server 21.04) with PPPoE ?

Domain Name System – DNS settings are overwritten by the ISP during PPPOE authentication?

I have a TP Link SafeStream router.

I set my DNS setting in my router under WAN configuration on the same page as PPPOE authentication to 1.1.1.1. Now the connection is properly established and the router shows the following:

Connection status Connected IP address xxx.xxx.xxx.xxx subnet
Mask 255.255.255.255 Standard gateway xxx.xxx.xxx.xxx primary
DNS 1.1.1.1 Secondary DNS 1.0.0.1

It should be noted that I have hidden my IP address, the actual address is obviously contained in the router information 🙂

Here's my problem, when I look at the router system logs, I see the following:

WAN1: IPCP negotiation succeeded. (Local=xxx.xxx.xxx.xxx, Peer=xxx.xxx.xxx.xxx, DNS1=MY ISP's DNS SERVER, DNS2=MY ISP's DNS SERVER2, MTU=1492)

Again, I've replaced my ISP's DNS servers with wildcard names, but you got the idea … the authentication process seems to override my DNS preference.
When I run a trace route, I also get a number of addresses from my ISP, but nothing to do with Cloudlflares 1.1.1.1 DNS.

I also set the DNS settings in my router's DHCP configuration and on individual devices. It doesn't seem like I can avoid this. I even tried to create a routing policy that forwards all DNS traffic to 1.1.1.1. However, the router's route information simply jumps from 1.1.1.1 to the DNS server of my Internet service provider …

Can I try something else? I know I could use a VPN, but I would prefer my entire network to just use 1.1.1.1

Any thoughts, comments or solutions would be greatly appreciated

How do I create DHCP srver from the PC with Ubuntu Server 19.10? (pppoe connection)

How do I create a DHCP server from a PC with Ubuntu Server 19.10?

The PC has two Ethernet cards. (enp3s5 – lan, enp3s6 – wan)

Pppoeconf is missing after installing Ubuntu Server 19.10

How do I configure this file for the PPPOE connection: /etc/netplan/50-cloud-init.yaml?

Networking – How do I fix the DNS problem with the dsl pppoe connection? Ubuntu 04/18

I configured /etc/resolvconf/resolv.conf.d/head as follows:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 1.1.1.1 
nameserver 1.0.0.1
nameserver 8.8.8.8 
nameserver 8.8.4.4

This is my /ets/resolv.conf file:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 1.1.1.1 
nameserver 1.0.0.1
nameserver 8.8.8.8 
nameserver 8.8.4.4
nameserver 127.0.0.53

So everything works fine. The problem is that I lose my internet connection every 1 or 2 hours and get the error dns_probe_finished. This can be solved by turning the connection off and on most of the time. And sometimes I have to restart my computer to get back on the internet. Can somebody help me with it?

Networking – How can I automatically connect PPPoE under Linux Mint?

So I have Linux Mint 19.3 with pppoe connection through Network Manager and after I restart my PC, this connection is lost, so I have to re-enter my user and password every time I turn on my PC. I don't want to use sudo pppoeconf because it's the same thing.
"Automatically connect to this network when it is available" is checked. Which value do I also have to set for "Connection priority for automatic activation"? This value is always set to "0".

How do I use NetPlan to configure PPPoE for the Etherent interface in Ubuntu Server 18.04?

everyone..

Can someone please help me to build a pppoe connection Ubuntu 18.04 server? I used to have Ubuntu 14.04 server, and I did it over pppoeconf but now it seems that it is no longer supported. I have found that I need to use netplan, but there is no information on how to set the pppoe connection there. On the net, people just show the examples of their wired connections, while I do not have a router, just a cable that comes with login and PSWD to my machine.
