Debian 10 new install network configuration issues

Postby alarin » 2019-11-26 16:59

Hello,

I have installed Debian 10 to Dell PowerEdge 1950 server first time. I can login with GUI now. Trying to get the internet to work with cable but no luck (seems it's not "plug-and-play" as my laptop linux). It will be used as a web server.
So my question - what files should i edit and what the settings must be and where to change them. Is there a tutorial on how to do this? I tried to edit some files as Wiki suggested but it still doesn't work. I can't ping anything and web browser is offline also, so there's no internet.

Any ideas?

Thanks and best wishes,
Andres

Please list what you have already tried (including any commands you ran and the content of any configuration files) so we know what doesn't work.

Again, please post the exact command used, along with the verbatim full output. Thanks.

At the top right corner i can open network settings, where there are many network settings to change - General, Ethernet, Proxy, IPv4 etc. Is it absolutely necessary to change individual files at all or i can make the internet work by just changing these settings? Why doesn't it just recognize there is internet cable plugged in?

So I can see there are 2 network cards there, which is probably good thing and i don't need to find any additional drivers hopefully.

With some command I found out that network adapter is called eno1

I have changed following files (content below the filename):

*** /etc/network/interfaces ***

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo eno1
iface lo inet loopback
allow-hotplug eno1
iface eno1 inet dhcp

*** /etc/NetworkManager/NetworkManager.conf: ***

[main]
plugins=ifupdown, keyfile

[ifupdown]
managed=true

***

That's all I have done so far.

No.

Yes.

Don't do that unless you know exactly what you are doing.
If you want to configure an interface with NetworkManager, don't configure it in /etc/network/interfaces.

Yes and No answers doesn't help me much. Please answer only if you have something constructive to say.

I found this video from Youtube https://www.youtube.com/watch?v=X1HyrSzmtKA and followed exactly these steps. Seems good little tutorial.

So i'm trying to bring the network up with "sudo ifup eno1" but it doesn't work.

"ip a" shows that eno1 is DOWN.

Could it be firmware problem?

I'm an old schooler, rather read than watch youtube-videos. :mrgreen:

Bridging cable and wifi usually requires a bit more, check https://wiki.debian.org/BridgeNetworkConnections. Read the whole page.
