Archlinux netctl configure static IP address when network cable is unplugged

Question

I have two servers with Archlinux.

Both of them are using static IP address with netctl. Both of them are accessed only with ssh (e.g. I have no keyboard and monitor).

Problem I facing is when server boot, if the network cable is unplugged, the IP address is not set up.

I tried with ExcludeAuto=no and with ForceConnect=yes, but no success.

I tried with ifplugd as well, but it does my server inaccessible so I did not test much.

I know I can probably do it with ip link or ifconfig directly, but I am looking for some more intelligent solution.

Configuration looks like this:

# /etc/netctl/lan1 

Description='A basic static ethernet connection'
Interface=enp1s0
Connection=ethernet
IP=static
Address=('192.168.0.3/24')
Gateway='192.168.0.1'
DNS=('8.8.8.8')

Answer 1

I checked netctl source code and found I need to add following lines into netctl profile:

ForceConnect=yes
SkipNoCarrier=yes

e.g. full profile must be something like this:

# /etc/netctl/lan1 

Description='A basic static ethernet connection'
Interface=enp1s0
Connection=ethernet
IP=static
Address=('192.168.0.3/24')
Gateway='192.168.0.1'
DNS=('8.8.8.8')

ForceConnect=yes
SkipNoCarrier=yes

if you search google for SkipNoCarrier=yes, you can find it online, but it is still not well documented on Archlinux website.
