Failed to start Networking for netctl profile <profile name>.

felippe_ro · 2018-11-29 19:22:51

Hello,

I have a fresh installation of Arch Linux on an old laptop and I am having troubles connecting to the wireless network at home. No issues in connecting to my switch using a network cable.

After booting into the new install, I installed "wpa_supplicant" then created the netctl profile manually (I don't want to use, for now, "wifi-menu").

cp /etc/netctl/examples/wireless-wpa /etc/netctl/MyWirelessProfile

nano /etc/netctl/MyWirelessProfile

Description='A simple WPA encrypted wireless connection'
Interface=wlp4s0
Connection=wireless
Security=wpa
IP=dhcp
ESSID='MyHomeSSID'
Key='MyPassword'
Priority=10

Then I try to start the profile:

netctl start MyWirelessProfile

but I got the error:

Job for netctl@MyWirelessProfile.service failed because the control process exited with error code.
See "systemctl status netctl@MyWirelessProfile.service" and "journalctl -xe" for details.

Examining the logs:

systemctl status netctl@MyWirelessProfile.service

Please edit your original post and wrap code with code tags

Nov 29 19:06:21 advent-laptop network[431]: The interface of network profile 'MyWirelessProfile' is already up

mabye

netctl stop MyWirelessProfile

felippe_ro · 2018-11-29 21:35:56

Thanks for your input, jbenge1.

I have stopped and started the interface many times before posting but it didn't work. In any case having the interface "up" before issuing "netctl start profile" should not pose a problem. I am not sure but the message

The interface of network profile 'MyWirelessProfile' is already up

is just a warning, not an error. I tested it with my other Arch laptop and it has no effect.

What is the output of

systemctl list-unit-files --state=enabled

felippe_ro · 2018-11-29 22:26:37

[root@advent-laptop ~]# systemctl list-unit-files --state=enabled
UNIT FILE        STATE  
autovt@.service  enabled
dhcpcd.service   enabled
getty@.service   enabled
sshd.service     enabled
remote-fs.target enabled

5 unit files listed.

I have installed and used iw to connect to the wireless network and it works:

3: wlp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 00:1f:3c:67:7b:18 brd ff:ff:ff:ff:ff:ff

I would very much like to use netctl with which I am quite familiar, though. With your help, there is still hope

seth · 2018-11-29 22:28:38

dhcpcd.service is controlling the interface and brings it up.
netctl will not try to control interfaces that are already up (thus likely controlled)

limit dhcpcd to the wired interface or drop it and rely on netctl profiles for everything.

felippe_ro · 2018-11-29 22:54:59

That worked, seth. Many thanks.

Now, I am not sure how to mark this topic as "SOLVED"...

You can marked it as solved by editing your first post and prepending [SOLVED] to the title.
