Ethernet card missing after DNS setup

Post by texmansru47 »

I was trying to get my DNS servers to work on my new install of Mint Linux 19. Before both my wired ethernet enps20 and the wireless were visible and working... not only the wireless is visible and I have to assume working. There was no resolv.conf and nothing in the interfaces files. So I added the following to each:

Interfaces:
auto enp2s0
iface enp2s0 inet dhcp
dns-nameservers 192.168.1.100 192.168.1.111 192.168.1.1
dns-search wilson.home
resolv.conf
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "systemd-resolve --status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 127.0.0.53
search home
I notice that when I change the nameserver in the resolv.conf file and restart the network services... it comes back to 127.0.0.53
