[SOLVED] installing buster 10.5: can't get networking setup

jjanderson5 · 08-11-2021, 10:57 AM

I am installing Bunsenlabs Lithium 2.1 which is a derivative of Buster 10.5. I have been following the instructions that I found at:

https://linuxconfig.org/how-to-setup...n-debian-linux

As suggested, I did the following steps:

1) systemctl stop NetworkManager.service
2) systemctl disable NetworkManager.service
3) Created a /etc/network/interfaces file:

Code:

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

allow-hotplug eno1

4) Created a /etc/network/interfaces.d/eno1 file

Code:

iface eno1 inet static
    address 192.168.1.235
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 8.8.8.8 8.8.4.4

5) ran "service networking restart"

6) ran "ip -a" and got

Code:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 5c:26:0a:32:c9:fa brd ff:ff:ff:ff:ff:ff

When I ran "ip -a", I was expecting the ip address of eno1 to be 192.168.1.235. This is not the case, and I have no connectivity to my router.

Can some one help?

I think ip always shows the ipv6 address. For ipv4, try ifconfig instead.

@hazel

Thank you for your comment.

When I run "ip -a" on one of my working pc's, I get:

______________________________________________________
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:18:8b:59:99:8c brd ff:ff:ff:ff:ff:ff
inet 192.168.1.250/24 brd 192.168.1.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::218:8bff:fe59:998c/64 scope link
valid_lft forever preferred_lft forever
_______________________________________________________

which shows both the ipv4 and ipv6 addresses. I am expecting the same on the new installation, which is running the same version of the linux o/s.

Rebooting should work but without NetworkManager the commands to manually start/stop the network adapter are:

sudo ifup eno1

or

sudo ifdown eno1

The PC was rebooted and the networking is working properly now. Kudos to michhaelk - he was right on target.
