localhost is off on my machine.

it's described in my /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth1
iface eth1 inet dhcp

but when i run route

 route -n" with wireless off

I get:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

how can i turn it on?

@tachyons Its perfectly on-topic here on Ask Ubuntu. Its a general networking question. Hence on-topic. – James Mar 31 '12 at 16:26
Thanks for the info :) – Tachyons Mar 31 '12 at 17:41

You can use ifconfig to check whether a network interface (e.g., the localhost interface (lo)) is enabled or not.

You can use sudo ifconfig lo up to enable the localhost interface.

sorry, "sudo ifconfig lo up" didn't change anything. maybe my case is different. – Pavel K. Nov 1 '11 at 18:42
