I'm running Ubuntu 12.04 LTE. I'm trying to connect via ethernet for the first time but have had no success. Ifconfig eth0 returns: eth0 Link encap:Ethernet HWaddr: 00:01:2e:3f:f1:a0 inet6 addr: fe80::201:2eff:fe3f:f1a0 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:68 errors:0 dropped:0 overruns:0 frame:0 TX packets:183 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8374 (8.3 KB) TX bytes:42944 (42.9KB) Interrupt:16 Base address:0x6c00 /etc/network/interfaces has auto lo iface lo inef loopback auto eth0 iface eth0 inet dhcp sudo /etc/init.d/networking prints: * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces * Reconfiguring network interfaces...
