[Netctl] can't get a basic DHCP to work [solved]

Hi all,

eth1-ethernet:
Description='A basic dhcp ethernet connection'
Interface=eth1
Connection=ethernet
IP=dhcp

netctl start eth1-ethernet:
A depedency job for netctl@eth1\x2dethernet.service failed. See 'journaltcl -xn' for details.

journaltcl -xn gives me a "Dependency failed for a basic dhcp ethernet connection" with not much more info....
I only have dhcpd installed.
Any ideas? Did I miss something?

Does eth1 exist? the current udev configuration names the network cards differently. use "ip link" to list the names.

Re: [Netctl] can't get a basic DHCP to work [solved]

I deleted /etc/udev/rules.d/80-net-name-slot.rules now eth1 is called enp3s0 but still the same error with netctl.....

Re: [Netctl] can't get a basic DHCP to work [solved]

Here is my /etc/netctl/ethernet-dhcp profile.
I had to change 'eth0' to 'enp0s20' as per 'ip link' info;

Description='A basic dhcp ethernet connection'
Interface=enp0s20
Connection=ethernet
IP=dhcp

Yes...it would be interesting...as a lot of us are new to netctl.

Thanks in advance.

Re: [Netctl] can't get a basic DHCP to work [solved]

No idea actually..... there was another file in /etc/udev/rules.d/ that forced my interface to be called eth1 deleted it....

Re: [Netctl] can't get a basic DHCP to work [solved]

I had a similar problem with both ether and wifi.

You might try adding your interface to the BindsTo array in the interface profile like so:

<code>
Description='Wireless with wpa_supplicant.conf'
Interface=wlp12s0
BindsTo=(wlp12s0)
Connection=wireless
Security=wpa-config
WPAConfigFile='/etc/wpa_supplicant/wpa_supplicant.conf'
IP=dhcp
</code>

The netctl.profile man page says this isn't necessary, but the netctl/systemd unit file that gets generated was bogus without the BindsTo line.

Perhaps more to the point, it works for me if I fill in BindsTo in the profile, but not if I leave it unset.

To see what changes, run:

<code>
du -a /etc/systemd | grep netctl
</code>

then look at the BindsTo and the After parameters in those files when BindsTo in the corresponding netctl profiles is set vs. not set.

I forget what happened to my ether interface, but for wifi the systemd file fingered wlan0.device, not wlp12s0.
