netctl fails with "link is not ready"

Hi all

I was hoping that you can help me out! I'm new to archlinux so please accept my apologies if I've missed something obvious.

I've just setup a new archlinux system on my HP N40L according to the archwiki beginner's guide and this btrfs guide.

I want to automatically connect to the internet with a static ip via ethernet cable.

netctl setup

cp /etc/netctl/examples/ethernet-static /etc/netctl/ethernet
nano /etc/netctl/ethernet
netctl start ethernet

netctl profile

Description='A basic static ethernet connection'
Interface=enp2s0
Connection=ethernet
IP=static
Address=('192.168.1.212/24')
#Routes=('192.168.0.0/24 via 192.168.1.2')
Gateway='192.168.1.1'
DNS=('62.24.128.17')

## For IPv6 autoconfiguration
#IP6=stateless

## For IPv6 static address configuration
#IP6=static
#Address6=('1234:5678:9abc:def::1/64' '1234:3456::123/96')
#Routes6=('abcd::1234')
#Gateway6='1234:0:123::abcd'

I can connect if I use these commands so there's no physical problem with hardware.

ip link set enp2s0 up
ip addr add 192.168.1.200/24 dev enp2s0
ip route add default via 192.168.1.1

or

systemctl start dhcpcd@enp2s0

I also tried to bring the interface up first.

ip link set enp2s0 up
netctl start ethernet

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

58 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

My modem router (192.168.1.1) handles DNS and DHCP (192.168.1.2 - 192.168.1.254).
I tried change the address pool to 192.168.1.2 - 192.168.1.253 and setting my computer's ip to 192.168.1.254 to avoid possible conflicts but this made no difference.
I have only installed packages from the base group and the packages openssh, amd-ucode and btrfs-progs.

thanks for the help - hopefully it's something simple I've missed

EDIT

I've found out that the following works

pacman -S ifplugd
systemctl start netctl-ifplugd@enp2s0.service

does anyone know why the beginner's guide wasn't working for me? is there a bug with netctl?

Re: netctl fails with "link is not ready"

I've had a similar problem not long ago, solved it by usng a custom service file as described here :
https://wiki.archlinux.org/index.php/Ne … IP_address


Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: netctl fails with "link is not ready"

Thanks for the pointer Lone_Wolf.

I've opted for the method you linked to as it means I can remove netctl and ifplugd.

[Unit]
Description=Wired Static IP Connectivity
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-enp2s0.device
After=sys-subsystem-net-devices-enp2s0.device

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/ip link set dev enp2s0 up
ExecStart=/usr/bin/ip addr add 192.168.1.254/24 dev enp2s0
ExecStart=/usr/bin/ip route add default via 192.168.1.1

ExecStop=/usr/bin/ip addr flush dev enp2s0
ExecStop=/usr/bin/ip link set dev enp2s0 down

[Install]
WantedBy=multi-user.target

I guess this is a solution sorts, although the original issue remains unsolved.

Is it worth cross posting to netctl on git?

Re: netctl fails with "link is not ready"

tadetter, when pasting code or command output, please use [ code ] tags, not [ quote ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and - in case of longer listings - more convenient to scroll through.

Re: netctl fails with "link is not ready"

It happens to me too. I think to switch to OpenRC (again). For me  The  Beginner's Guide works but netctl and wifi-menu don't.
