is there a way i can change the DNS server on the command-line without having to change anything on the disk?
i recently booted into the rescue session and i got an IP address (using DHCP) but no DNS server. as my network config is usually done with the
nm-applet in the desktop session and not in
/etc/network/interfaces i would like to be able to provide a DNS server just for this rescue session and not write anything on disk.
this is usually possible by editing
resolvconf seems not to be running in the ubuntu 14.04 rescue session.
i was hoping there was something similar to the network configuration where i can configure an interface without having to edit a file:
# ifconfig eth0 192.168.2.5 netmask 255.255.255.0 # route add default gw 192.168.2.1
is there a way to do this for DNS in a rescue session on ubuntu 14.04?
