When I connect via Network Manager I get two servers in /etc/ppp/resolv.conf and mywork.com.br as a search domain in /etc/resolv.conf. While it allows me to resolve names in that network it … Read more

In the good old days in which I was using Slackware I just needed to edit /etc/resolv.conf and my job was done. After figuring out that /etc/resolv.conf is actually generated by resolvconf I edited /etc/resolvconf/resolv.conf.d/head as … Read more

Answer You … Read more

I use Lubuntu 17.04, on which the NetworkManager service (subsystem?) performs some configuration actions when I connect to a new network. One of these is (re)setting the /etc/resolv.conf file to: # Generated by NetworkManager search some-local-domain-here nameserver 127.0.1.1 at least that’s what I get when DHCP is used. There’s a dnsmasq instance which listens on … Read more

How can I make it append stuff to the end (i.e. give lower priority to these settings)? Answer You can use the resolv.conf.head and resolv.conf.tail files … Read more
I’ve got two network cards, one is onboard and the other is an added PCI card. I also created a bridge interface for my KVM virtual machines to use, so my desktop (host) uses the enp3s0 interface and the VMs (guests) use the enp4s3 interface through a bridge that I created named VM-NetBridge. Here’s the … Read more
