When I want to login into my Ubuntu System, it appears

waiting for network configuration

and the second is

waiting for more 60 seconds

then it appear when we use the common Ctrl+ALt+F1 the Screen System, which caused the problem I think is I can't connect to the Internet.

So I changed something in /etc/network/, but now I want to it go back to the original the network configuration, but I don't know what to do.

Anyone can help?
Can anyone give detailed answers?

Thank you

  • for you advise,so I gives the network configuration as follows: #interfaces(5) file used by ifup(8) and if down(8) auto lo# iface lo inet loopback auto eth0 iface etho inet dhcp auto eth0 I have Omission some comment – user2900037 Mar 21 '14 at 7:24

If you edited your /etc/network/interfaces file and want to return to a default Server config, try 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 eth0
iface lo inet loopback

# The primary network interface
iface eth0 inet dhcp

This assumes that you are getting an IP address from DHCP on the eth0 (primary) Ethernet interface.

  • Run ifconfig and post the contents of the output. – douggro Mar 22 '14 at 19:05

Edit this file sudo nano /etc/init/rc-sysinit.conf

Go to the line; start on (filesystem and static-network-up) or failsafe-boot

Change to; start on (filesystem) or failsafe-boot

Than restart..
