Question

localhost is off on my machine.

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?

Answer 1

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.
