Setting up network on 'vanilla' bullseye

#1 Post by otalado »

I downloaded weekly Debian 11 net install ISO for ARM64 (15th FEB 2021-02) and installed it on my Raspberry Pi 4. During install, the network was not recognized, so I continued without it. After the install was finished the network did not work. When I checked with ip a command, I found an ethernet interface, but the status was DOWN. I set it UP with the ip link set dev xxzzyy up. At that point, I should be able to ping the network by IP Address, yet for any address which I try to ping, I am getting the message: Network is unreachable. Command ip neighbor show shows nothing.

At that point, my limited knowledge is exhausted. I was searching the forums, all hits I managed to get were either obsolete or irrelevant. So, I'll appreciate any suggestions or links with some explanation, ...

@Hallvor, @arochester: lspci command you asked me to try produces no output in both your cases. If I read the man page for lspci command correctly, data is stored in /usr/share/hwdata/pci.ids. Unfortunately, there is no directory /usr/share/hwdata.

No. The interface is UP but is not configured with any IP addresse and route.

As expected.

Code: Select all

ip addr add ...
ip route add ...
or, if you have a DHCP server,

Code: Select all

dhclient xxzzyy
For persistent configuration, consider using /etc/network/interfaces or any other network manager.

@p.H
Sigh! Now, that you gave me an answer, it seems pretty obvious. As they say, everyone has 20/20 hind vision :(
Let's hope I won't forget this one (too soon).
Many thanks!
