Hello, I've just installed arch and I was able to connect to the internet automatically via the boot disk, however after running the following commands on my newly built system (after reboot):

systemctl  enable dhcpcd@eth0.service
systemctl start dhcpcd@eth0.service

I got the following errors in journal

 
Timeout waiting for device sys-subsystem-net-devices-eth0.device.
Subject: Unit sys-subsystem-net-devices has failed.
Defined-By: systemd


The result is timeout.
Dependency failed for dhcpcd on eth0.
Subject: Unit dhcpcd@eth0.service has failed
Defined-By: systemd

Any ideas on what the dependency is and what I can do to solve it? Like I said, I was able to ping google from the bootdisk...

My guess is this is back to the step where you use ip link command to find out what interfaces you have.

I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...
Look ma, no mouse.

Re: New network naming schema in systemd 197

Hi,

I have installed Arch on Asus Eee PC 901 and I'm experiencing
some problems with Wireless networking.

During the installation, I booted from USB pendrive, created partitions, filesysems, and followed all steps of typical Arch installation. I also used wifi-menu to get Wireless connectivity.
BTW, I also installed wireless_tools, netcft and wifi-menu in the chrooted system (one of the Eee PC wiki articles suggested that).
So, the installation went without any troubles.

The problem is that after reboot to the newly installed system, I can't get the wireless card working.
It loooks like the devices are somehow blocked, rmmod/modprobe of ath5k module does not help.

Here are details of the two configurations relevant to networking:

1) listed when I boot to live Arch from the USB pendrive
2) listed when I boot to the installed Arch


1) Live system

I have noticed some differences between these two configurations that seems to be relevant to the problem.
For example, in dmesg messages I see some messages about wlan0, the 1) shows:

[   14.061500] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

whereas the configuration 2) shows:

[    3.387054] systemd-udevd[136]: renamed network interface wlan0 to wlp1s0

I searched the Web a lot trying to figure out what's the problem and many articles mention use of rfkill.
For example, all these seem to be direclty related to my problem:

Netcfg Tips wiki on Eee PC

Wireless network stopped working after updating to gnome3 thread

AcerAspire 3500 ath5k rfkill hard block

Interestingly, there is no rfkill command available on the installed system with configuration 2),
although the rfkill module is loaded. I'm curious why the installer skipped the rfkill.

On the live system 1), I see /etc/conf.d/rfkill file which is missing from the installed system 2):

# /etc/conf.d/rfkill
# Configuration for the rfkill startup script
#

# List of devices to block on startup (space-separated)
RFKILL_BLOCK=""

# List of devices to unblock on startup (space-separated)
RFKILL_UNBLOCK="all"

Is that possible the missing or incomplete rfkill setup on the installed system 2) is the root of the problem?

I have tried to juggle the ath5k (wireless) and atl1e (ethernet) modules manuall to see if there is
any difference. I also played with hardware switching of WiFi on the Eee PC.
I always see the same message in dmesg: renamed network interface wlan0 to wlp1s0.

Unfortunately, web searching does not give anything useful about the wlp1s0.

If I need the rfkill installed indeed, can I do it by booting to live Arch
then arch-chroot the root partition, and pacman missing packages?
Is that enough?

I'd be thankful for any help in solving this mystery and helping me to get the WiFi working.

Re: New network naming schema in systemd 197

Systemd has brought about new behaviour.  It will rename your network interfaces while booting.  Just use the renamed interface it gives you.  The reason it now does this is because of race conditions when naming interfaces.  Previously interfaces weren't guaranteed to always get the same names.  With the new systemd behaviour an adapter interface will always receive the same name even if you change the hardware configuration of the computer.  So, short: just use the name systemd gives you as part of the boot process.

Re: New network naming schema in systemd 197

https://wiki.archlinux.org/index.php/Be … e#Wireless

If you're coming from another distribution, or if this is your first time installing Arch Linux since the deprecation of the old interface naming scheme, you might be surprised to learn that the first wireless interface is not named "wlan0". In fact, none of the interfaces are automatically prefixed with "wlan" any longer. Don't panic; simply execute iwconfig to discover the name of your wireless interface.

Warning: At the moment, netcfg's wifi-menu, when executed without arguments, will look for "wlan0". Execute wifi-menu with your interface as the argument in order to use it.

Thanks for the explanation. If I only had linked my problem to the new features of systemd, I would have not contributed to this growing thread smile

Re: New network naming schema in systemd 197

Hey,

I just did a fresh install on my server (previosly debian) and a can't get my internet working, my network cards don't even show.
if i type "ip addr" is get:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

And "lspci -v" gives: (after some cleanup)

Re: New network naming schema in systemd 197

Hello arch community,

I always used arch linux, but a while ago I decided to fresh install it again, to get rid of a lot of crap, like useless files and libraries, bad programs and a lot of other junk. So I grabbed my disc and reinstalled following the official arch installation guide (I have always followed it to not screw things up), but after the installation, I can't connect to the internet. I have reinstalled arch a lot and yet installed on another computer (desktop), but still the same thing happened.
When I try to connect via wifi-menu, I got no wlan0 device message.

I tried various solutions but none of them worked for me. Any ideas?

Re: New network naming schema in systemd 197

After installing Arch from scratch using the 2013-02-01 image my system boots fine but without any network.  I've tried everything I can think of still to no end... systemctl enable dhcpcd@eth0.service was used during install.  They system was running fine but I had a HDD failure so I know the NIC is good because it connects fine when I boot up the image.  Any thoughts on what this could be?


Thanks for any help

Yeah Sorry, I was in a panic because I have a paper do in 2days... I normally search hard before I post but I wasn't using a good enough search string... Right after I posted I found the post that explained everything.

Re: New network naming schema in systemd 197

I'm a brand new Arch user, but I have wetted my feet with Ubuntu before. I did a brand new install of arch yesterday following this guide

Because I'm using only a wired connection with a dynamic ip I enabled the dhcpcd service with the command 

# systemctl enable dhcpcd@eth0.service

but when I reboot and login I am not connected to my network and 

# ping -c 3 www.google.com

returns an unknown host error

and when I attempt to enable eth0 manually with 

# sudo dhcpcd eth0

it returns eth0: interface not found or invalid. Believing it to be a bad install I wiped the partitions and reinstalled, this time using ifplugd alternateive method found in the guide.

#pacman -S ifplugd
# cd /etc/network.d
# ln -s examples/ethernet-dhcp .
# systemctl enable net-auto-wired.service

but I have the same problem and receive the same errors

I then attempted a solution I found on a forum post from 2009

# lspci | grep Eth
00:0a.0 Ethernet controller: nVidia Corporation MCP78S [GeForce 8200] Ethernet (rev a2)
07:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
# lspci -s 00:0a.0 -n
00:0a.0 0200: 10de:0760 (rev a2)
# grep  -e '10de.*0760' /lib/modules/`uname -r`/modules.pcimap
forcedeth            0x000010de 0x00000760 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0

however 

# grep  -e '10de:0760' /lib/modules/`uname -r`/modules.pcimap

returned a no such file or directory error on the path  /lib/modules/3.7.7-1-ARCH/modules.pcimap  (yes, I did substitute my Ethernet controller for the examples')

Both the ifconfig and rc.conf commands are not found (I believe because I have not installed them yet) and I am using the newest release (2013.02.01)

Re: New network naming schema in systemd 197

Welcome to archlinux.  Please make sure to do your own searches before posting new issues.  This particular issue has been covered ad naseum over the past month.  There is a stickied thread in the forums dedicated to this change.  And there is a big red highlighted box in the very same wiki page you said you followed: https://wiki.archlinux.org/index.php/Be … connectionThe whole netowrking section of that wiki page elaborates on this in detail.

Re: New network naming schema in systemd 197

hello, I have read this new naming for those devices now and I do have both when I type ip link. Basically I got:
1:lo
2:enp5s0
3:wlp9s0

2 and 3 down.

But I can`t connect to wlp9s0, and when I type ip link set wlp9s0 up, I got:

RTNETLINK  answers: Operation not possible due to RF-kill

so wifi-menu wlp9s0 can`t connect to my network, saying Interface unavailable.

However, enp5s0 works when I set it up and enable dhcpcd service.


What can I do to connect via wifi?

This is unrelated to the current issue, please don't hijack threads:
https://wiki.archlinux.org/index.php/Fo … _Hijacking

What has searching told you? Toggle the kill switch and bring the interface up...
If that doesn't work, open a new thread and include all of the steps you have tried and any relevant error messages.

Welcome to archlinux.  Please make sure to do your own searches before posting new issues.  This particular issue has been covered ad naseum over the past month.  There is a stickied thread in the forums dedicated to this change.  And there is a big red highlighted box in the very same wiki page you said you followed: https://wiki.archlinux.org/index.php/Be … connectionThe whole netowrking section of that wiki page elaborates on this in detail.

Is it worth adding a cautionary warning/link in the wiki Beginner's Guide for the case where there is more than one wired ethernet NIC in the motherboard?  I have had quite a few issues with this until I read the details at https://wiki.archlinux.org/index.php/Ud … ork_device - even experienced linux users can be caught out by that issue (I have been using linux exclusively for a decade!)

Re: New network naming schema in systemd 197

Hello.

I have seen a few other posts regarding this issue, but none of them have resolved my problem. I have used linux for a while (Ubuntu/Debian, Fedora, Opensuse), and I really want to use Arch. I followed an instalation guide from http://lifehacker.com/5680453/build-a-k … he-process and everything went smooth, except that my internet was not working when I rebooted. Everything I know isn't working.

(ifconfig) - command not found, (rc.d)- command not found (ip link set eth0 up) - cannot find device 'eth0'

Maybe somebody else knows whats up?

Re: New network naming schema in systemd 197

There's a stickied topic in the network subforum all about the new networking device naming system, did you read that?

Sakura:-
