Re: internal network

[Patrick Dupre via users <users@xxxxxxxxxxxxxxxxxxxxxxx>]

Thank for the feedback.

 

It is just a temporally solution. I must get a new doogle at the end of next week.

Before I had PC A with the 2 internet interfaces connected to PC B and PC C.

The setup was easy, and new had problem.

 

Now

From PC B

nmcli connection show
NAME                           UUID                                  TYPE      >
Teucidide                      8f233537-6418-3b76-abb7-cd0249809ac0  ethernet  enp3s0
A20Pro                         f8647833-80fd-49d1-8ae8-bbd959ca74b7  wifi      wlp2s0
lo                             4648a7f6-3db2-4582-8f6b-9079832dae56  loopback lo

Teucidide is

enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.42.0.1  netmask 255.255.255.0  broadcast 10.42.0.255
 

 

On PC A

NAME                UUID                                  TYPE      DEVICE 
Sappho              4a0b706f-011e-395a-a9fa-5e212ad0b60a  ethernet  enp2s0 
Homere              dd613977-f953-3da3-8610-6ff7442e1860  ethernet  enp1s0 
lo                  78b25b4b-efda-4ef5-a6a9-e962f02fdbce  loopback  lo     
virbr0              ee77b5b7-d886-41a7-816d-6761a7772d0d  bridge    virbr0 
 

Sappho is

enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.42.0.2  netmask 255.255.255.0  broadcast 10.42.0.255
 

Homere is

enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.42.0.3  netmask 255.255.255.0  broadcast 10.42.0.255
 

What should I modify to have at least PC A (in addition to PC B) accessing to the rest of the world,

i.e., to access to A20Pro through PC B?

 enp3s0 and enp2s0 are wired (enp1s0 is wired to PB C)

 

I set the gateway and now it works.

 

Now

1) I wish to use internet from PC A.

I guess that I need to set a name server

But not possible manually

nmcli connection modify <connection_name> ipv4.dns <dns_servers>

(From: https://idroot.us/fedora-41-network-configuration/)

 2) How do I need to set for PC 3

From PC A

From PC C

I tried several things but none works

Your life would be made a lot simpler if you had a small switch or router, as Tim suggested. You can even get USB-powered devices.
