netctl DNS server selection

hargoniX · 2018-04-14 13:20:15

I set up an own DNS server in my network yesterday and now tried to configure netctl to use it with:

Description='custom DNS profile'
Interface=wlp3s0f0u3
Connection=wireless
Security=wpa
ESSID=FIREBIRD
DNS=('192.168.188.231')
IP=dhcp
Key=mygreatkey

However my resolv.conf always looks like

# Generated by resolvconf
domain fritz.box
nameserver 192.168.188.1
nameserver 192.168.188.231

after i start the profile, so my machine always uses the nameserver it gets from the DHCP server instead of my own.

How can I configure netctl to only use my DNS server and ignore the one from DHCP

How about just editing the config of your DHCP server to provide the correct DNS address?

I dont have access to the router so i can not do that.

Tried

DHCPClient=dhcpcd --nohook resolv.conf

?

Did not work.

You can try this. According to the source, setting DhcpcdOptions should be possible
https://git.archlinux.org/netctl.git/tr … hcp/dhcpcd

DHCPClient=dhcpcd
DhcpcdOptions="-L --nohook resolv.conf"

But in any case, if DNS is set, then netctl should automatically prevent dhcpcd from running the resolv.conf hook.

    # If using own dns, tell dhcpcd to NOT replace resolv.conf
    [[ $DNS ]] && options+=" -C resolv.conf"

I tried that too, did not work either. Maybe there is something wrong with my dhcpcd config?

Ruling out the d'ohh: you do have dhcpcd installed and in use (running) and are not defaulting to dhclient?

hargoniX · 2018-04-14 19:53:53

Yes, I do.

Have you tried editing /etc/dhcpcd.conf?
