I have installed a basic command-line system and didn't configure networking at setup time. Namely, I have booted from Lubuntu 14.04 Alternate CD, pressed F4 and selected 'Install a command-line system'.
Now I only have the loopback interface configured:
$ ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:50121 errors:0 dropped:0 overruns:0 frame:0
TX packets:50121 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:4381349 (4.3 MB) TX bytes:4381349 (4.3 MB)
I know my hardware (both eth0
and wlan0
interfaces) works ok if I just install the default Ubuntu image with a graphical installer.
How do I configure wired and wireless network interfaces after installing a basic command-line system?
