No eth0 device

Hi guys,

I've installe archlinux. All works, except the wired network connection (never tried wireless).
When i was using the live system, it worked. But since I've installed arch on disk it doesn't work anymore.

"ip addr show" shows only lo.No eth0 or eth1.

I tried dhcpcd commands because i read in other threads to try this, but nothing works.
So what could be wrong? Do i have to reinstall my system?

Re: No eth0 device

During the 197 systemd update the naming scheme of network interfaces changed, and is default for new installations. Check this.

Re: No eth0 device

I couldn't solve the problem with this article.
But now i know, that my devices are named as enp3s0 and wlp5s0.
But how can i tell the system, that enp3s0 is my eth0 device?

Re: No eth0 device

This post gives a bit more info. In this thread the change is discussed.

I can't help with specifics though, because existing installs have to opt in for the change, which I haven't done yet. But maybe those links help you further.

Re: No eth0 device

You should make sure your systemd is running directly.
Check it by
# systemctl status
Then check its outputs if there is D-bus fail.

Re: No eth0 device

Follow the beginners guide to manually connect to the internet:
https://wiki.archlinux.org/index.php/Be … uide#Wired
# ip link
# ip link set enp2s0f0 up
#ip addr add 192.168.1.2/24 dev enp2s0f0
# ip route add default via 192.168.1.1
# nano /etc/resolv.conf

This is the best method to begin with, because every step will give you output in case of errors.

Re: No eth0 device

# ip link
# ip link set enp2s0f0 up
#ip addr add 192.168.1.2/24 dev enp2s0f0
# ip route add default via 192.168.1.1
# nano /etc/resolv.conf

Did all this steps except editing /etc/resolv.conf. I live in a dorm and have to use their connection to the internet. Their domain is registered so i think it should be allright.
"ip link" lists 1.lo 2.enp3s0 3.wlp5s0
When i use "ip link set enp3s0 up", enp3s0 stays at position 2.

Re: No eth0 device

So does it work now? You've got an ip address, the interface is up...

Re: No eth0 device

Hi,

I may be have the same problem. I have set eht0 to UP state but cannot see it in ''addr'' state. If is this another problem I'll create new thread.

This is output of link:

# ip link show
1:  lo:...
~
2:  etho: <BRADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
       link/ether <MAC.ADDR> brd ff:....:ff

Then I start dhcp client:

# dhcpcd eth0
dhcpcd[5953]: version 5.6.4 starting
dhcpcd[5953]: eth0: rebinding lease of 192.168.1.117
dhcpcd[5953]: eth0: acknowleded 192.168.1.117 from 192.168.1.1 'ÿ'
dhcpcd[5953]: eth0: checking for 192.168.1.117
dhcpcd[5953]: eth0: leased 182.168.1.117 for 7200 seconds
dhcpcd[5953]: eth0: etho0: MTU set to 576
dhcpcd[5953]: forked to background, child pid 5983

BUT in addr I cannot see the result IP address:

# ip addr show
1. lo: <LOOPBACK,UP,LOWER_UP> ....
     inet 127.0.0.1/8 scope host lo
#

I tried to set IP address manualy but with the same result. I cannot ping any server and continue with installation of ARCH.

Re: No eth0 device

So it works fine. Just enable the dhcpcd service then (optionally explicitly for that interface)

Re: No eth0 device

using

dhcpcd enp3s0

works!

I tried that command after installing the system, but with dhcpcd eth0.
So I think it didn't work, because my device is named enp3s0
I have to retype dhcpcd enp3s0 after rebooting, but I think there is a solution in the beginners guide.

Thanks for your help guys!

or symlink dhcpcd@enp3s0.service yourself.

Re: No eth0 device

I realize this question might not be immediately answerable since it's an upstream issue, but I'm wondering:  Is this new naming convention a permanent change, or is it some sort of temporary glitch particular to systemd-197?

Permanent, unless a better solution is found.

Is not a glitch; read official info here: http://www.freedesktop.org/wiki/Softwar … rfaceNames
