I am running Ubuntu server 20.04 on a Raspberry Pi 4 and I am having difficulty updating the DNS entry in resolv.conf. resolv.conf points to the nameserver 127.0.0.53; however, I disabled the systemd-networkd dnsstublistener so I could run my own DNS server. How can I change the nameserver to point to 127.0.0.1 instead?
When i want to boot up my laptop it shows this error to me
[FAILED] Failed to start Dispatcher daemon for systemd-networkd
Please help me.
I have my eth0 interface configured for DHCPv4 via netplan:
network:
version: 2
renderer: networkd
ethernets:
eth0:
dhcp4: true
dhcp6: true
optional: true
How do I tell systemd-networkd to renew my DHCP lease? I know with dhclient it's as simple as dhclient -r eth0 && dhclient eth0, as explained in many other answers on this site, but how do I do it for systemd-networkd?
I'm in Ubuntu 18.04 Server.
Is it sufficient to have one of these three in Ubuntu 19.04? Is it possible to have all three and how to configure them so they were not conflicting?
Does systemd-networkd started by networking.service?
I am learning to use netplan. When writing a YAML configuration file I need to know which renderer to use, either NetworkManager or networkd.
How do I know if I am running NetworkManager or networkd?
