I just installed ubuntu 12.04.1 alternative install (for raid 0 on some disks). I Have some problems with the net. I'm at school, we use cable, and it got IPv6.

If I run ifconfig eth0 heres my output:

eth0      Link encap:Ethernet  HWaddr e0:cb:4e:87:ff:db  

          inet addr:128.39.194.217  Bcast:128.39.194.223  Mask:255.255.255.224

          inet6 addr: fe80::e2cb:4eff:fe87:ffdb/64 Scope:Link

          inet6 addr: 2001:700:1100:8008:48f7:c23:1d87:da6c/64 Scope:Global

          Interrupt:68 Base address:0x6000

My /etc/network/interfaces look like this:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).



# The loopback network interface



auto lo

iface lo inet loopback

# The primary network interface

auto eth0

# NetworkManager#iface eth0 inet dhcp

# NetworkManager#hostname 2001:700:1100:1::4

# This is an autoconfigured IPv6 interface

iface eth0 inet6 auto

(I had to remove the hash tags, because of the BIGFONT i get on ask ubuntu)

The "network manager" says that I'm not connected.

Let me know if you need any more information. :)

Ok so I have a way better answer then I had before.

How about we try this.

Open a terminal.

gksu gedit /etc/rc.local

Add: sudo dhclient eth0 like so.

#!/bin/sh -e

#

# rc.local

#

# This script is executed at the end of each multiuser runlevel.

# Make sure that the script will "exit 0" on success or any other

# value on error.

#

# In order to enable or disable this script just change the execution

# bits.

#

# By default this script does nothing.

sudo dhclient eth0

exit 0

Save & Close. Reboot and should work.
