Arch Linux = NetworkManager and dhcpcd

Amarildo · 06-23-2014, 11:20 PM

After 4 hours doing research, I came to the conclusion that NetworkManager will conflict with dhcpcd no matter what I do, no matter what configuration I try. Disabling dhcpcd, however, fixes everything related to my wired and VPN connections.

Is it really possible that NM wants to be the King of the Hill and deal with dhcpd stuff by itself? Is there any security issues using it alone with the dhcpcd module disabled? Basically what I do:

Code:

# pacman -S openvpn

Code:

# pacman -S networkmanager-openvpn

Code:

# pacman -S kdeplasma-applets-plasma-nm

Code:

# systemctl stop dhcpcd ; systemctl disable dhcpcd

Code:

# systemctl start NetworkManager

i don't think dhcpcd provides security, it's simply needed to resolve addresses and renew leases.

i think NM would start its own instance of dhcpcd and it simply gets confused when it's already running.

afaik i'm not using NetworkManager (although it's installed), but the same happens with netctl.

I'm just going to chime in and say NetworkManager is the devil and leave it at that.
