having to manually turn on and dhcpcd network interfaces every startup

Every time I login I am having to turn on the network interface manually with ip link set enp0s3 up, and turn on dhcp with dhcpcd enp0s3. Do I have to modify a file to automate this process? ..

Thanks

Re: having to manually turn on and dhcpcd network interfaces every startup

Unlike the installation environment, an installed system has no automatic network setup configured.

Configure the network again for the newly installed environment: see Network configuration and Wireless network configuration.

"systemctl enable dhcpcd@enp0s3.service" is one simple solution.

I just enter that into the command line? That's it?

Re: having to manually turn on and dhcpcd network interfaces every startup

I was told dhcpcd is not needed anymore (after wasting hours, trying to get it to work properly with my ancient fritzbox sl) and eventually:

systemctl disable dhcpcd.service
systemctl enable systemd-networkd.service

solved all my connectivity problems.

edit: fixed typos

It should say 'service' or just

systemctl enable systemd-networkd

See https://wiki.archlinux.org/index.php/Systemd-networkd

Sorry. Fixed/edited my post and removed the 's', so it's service instead of services.

Note:
Systemd-networkd requires aditional configuration unlike dhcpcd. On the other hand dhcpcd is slower.

Re: having to manually turn on and dhcpcd network interfaces every startup

I use the netctl-auto@wifi-card-here and netctl-ifplugd@ethernet-card-here method on a laptop and I don't have dhcpcd or dhclient installed.  I have found this to be a nice setup on any computers I have that use wifi and ethernet on that same system.

LiquidAurum, what have you tried so far (apart from the one command above that didn't work for you)? What documentation have you followed? Did you read the Network Configuration page that alphaniner linked? Or the systemd-networkd page that karol linked?

The command doesn't work immediately, just after restart the computer.
If it's needed instantly, you'd enforce

# systemctl start systemd-networkd

But if you show us what the system got to say

# journalctl -b -u  systemd-networkd
# systemctl status systemd-networkd
