I have a Ubuntu 12.04 x32 running in a Chroot environment (using Crouton) on my Chromebook. It runs perfectly, and can access the internet. However, it cannot access computers on the local network (it won't discover Minecraft LAN devices, but others can discover and NOT connect to mine), and it won't discover or connect to any LAN devices in Nautilus (error message when opening "Windows Network" saying "Unable to Mount location" and "Failed to retrieve share list from server").

Here is my /etc/hosts file, as default when installed:

127.0.0.1 localhost

::1     localhost ip6-localhost ip6-loopback

fe00::0     ip6-localnet

ff00::0     ip6-mcastprefix

ff02::1     ip6-allnodes

ff02::2     ip6-allrouters

Can someone please help me with this? I need to access samba shares (Raspberry Pi NAS and my desktop computer file shares), and Minecraft LAN would be a bonus :)
