Hello Everyone,

I'm new to Debian 9 and a server (PowerEdge R610) I just got from ebay to mess around with.

Usually I mess around with Kali Linux but I'm looking to run a web server on this old server I just got.


I thought this was going to be a simple OS install.
However, looks like Debian isn't allowing me to connect via ethernet.

I figured I'd just grab my ethernet cable and hook it up and that would be it.

However, doesn't seem like Debian is picking up anything.


I did try to bring up the eno1 interface however, the terminal came up with something a long the lines of
"Eno1 interface unknown"

Here's some pics

I'm mainly just trying to run a web server on this PowerEdge R610.
I decided to go with Debian 9 as it's been around for quite sometime and I've heard is the to go to OS for running a web server.

Let me know if you'd like me to run any commands on the terminal to help you help me.

Thank You and any help is appreciated.

i've never heard of an eno1 interface.
please show us the commands issued & output received.
post it between code tags.
also the output of

It looks to me like there are four ethernet interfaces detected and usable, eno1, eno2, eno3, eno4. The "error" in your screenshot seems to be:

This is not a "real" error, since it seems that you just don't know what commands to enter for the "ip" command. If you want to see a list of interfaces and addresses, use the following command:

or simply
Which is what you typed in after. That is all fine.

My first guess is that maybe the ethernet cable is plugged into the wrong port, or the connection is not configured properly (look in the IPv4 settings on the connection in particular - you want DHCP, assuming you've got a router or some other DHCP server active on the network).

At some point, you'll probably want to learn how to set up /etc/network/interfaces rather than use the Network Manager GUI to set up and configure the network interfaces. Network Manager is a really nice tool for laptops, but its capabilities are extremely limited when it comes to handling multiple ethernet interfaces.

Debian 9 is extremely well suited for running a web server.

Having said this, one does not normally install a GUI and thing like networkmanager on a server. Using networkmanager requires that you don't have the interfaces setup in /network/interfaces.

If you install Debian using netinstall it will detect the first network interface. Then is requests a DHCP address. It is unlikely that you passed this step succesfully and the network interface does not show up after installation.

With Dell it is also possible and likely that the NIC uses non-free drivers. A netinstall does not pass beyond the point of NIC detection, but a CD install does. So I assume you have installed from a CD and ignored warnings about firmware being not available.

I recommend that you download a netinstall with non-free firmware included and do a netinstall. And see where it gets stuck.

I am not a fan of reinstalling, but without network connection I don't see how you can install the non-free firmaware.

Wired Ethernet cards usually don't have extra firmware blobs. During the install it should give you a choice of all of the configured interfaces.

I am sorry but I have to contradict this. They do. I am sure at least one Dell PowerEdge R210 server had this problem. That is a few years ago now, but messages about non-free firmware for NICs in Debian have not become less frequent. Especially Realtek.

eno1 should mean it is supported in kernel but that assumes you actually have an enoX nic(s) and are not using a prior distro.

eno1 means predictive naming scheme. Every time you boot the exact nic should be in that exact same place.

Use IP configure or gui to configure. Be sure to start with lspci to see what nic model maybe.

If this R610 has a Broadcom NIC 5709 installed it uses non-free firmware.

Unfortunately the OP has already lost interest and leaves to the usual LQ members to have a discussion among themselves. He could have informed us about the installed NIC.
