Re: Network configuration

Hi Yamakaky,

netctl, wpa_supplicant, and NetworkManager all manage your network interface
connections (your OSI layer 2 connections). dhcpcd and dhclient are DHCP
clients, responsible for automatically getting you an IP address (OSI layer 3).

More information about these tools can be found on the Arch Wiki:
https://wiki.archlinux.org/index.php/Wireless#Wireless_management

I prefer to use wpa_supplicant because it is very simple, and exposes much of
the low level stuff. I have heard that it can be annoying to maintain, but I
haven't reached that drawback yet. My strategy is to use the most minimal tool
available until I understand why it is better to use higher level tools.

I would like to move to NetworkManager because I run chronyd and want to bring
it online and offline as my Internet connection comes and goes, which
wpa_supplicant does not support AFAIK. But I haven't been able to get it to
work yet.

For my DHCP client I chose dhcpcd, for no particular reason.

Hope that helps.
Dolan
