i know there is already a post about this topic here:
/etc/resolv.conf keeps resetting itself
but i already checked that
network-manager
dhclient
resolvconf
are not installed on this server system.
could dnsmasq be responsible for changing the resolf.conf file? but that wouldnt make much sense since it reads its "upstream" dns servers from it...or does it not?
my /etc/network/interfaces looks like this:
source /etc/network/interfaces.d/*
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.178.215
netmask 255.255.255.0
gateway 192.168.178.1
what else would change that file...and why?
