Problems (eth0) staying connected to the Internet

[specialist125]

Ok I recently installed etch and eveything was working fine for the past 3 days. Yesterday I rebooted the computer to do some work in windows. When I started debian again my internet connection wasn't found. So, I figured out that my eth0 connection was disable. I went to kde control center
1. Internet & Network
2.Network setting
3 Enable etho
Everything was working fine again. Today after rebooting from windows I seem to have the same problem. I tried doing what I did yesterday but that did not work. When I try to enable eth0 it switches back thus not allowing me to change the setting. I decided to restart the computer agaian and during bootup I saw that some things where failing in startup. I think it said /etc/network/???? I didnt catch this last part. After trying to reset the eth0 once again and having no luck I restart the computer so I could come to the forum. During the shutdown process their were also errors/fail processes which I belive is "up-down"(this could be wrong). I recall seeing something similar in the /etc/network/??? directory. I dont know what is wrong with it. Everything else seems to work fine. I have to use Window to connect to the internet now. Oh I am not on a network.

Do you lose connection only when booting after Windows or after any reboot?
Try:
ifconfig eth0 up
see if that will get your connection. Also, can you display what your /etc/network/interfaces here?

Edit: What does:
ifconfig
give you?

this is what I got

the-cage:/home/specialist125# ifup eth0
/etc/network/interfaces:20: too few parameters for iface line
ifup: couldn't read interfaces file "/etc/network/interfaces"



This is the /etc/network/interfaces file.

# 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
address 127.0.0.1
netmask 255.0.0.0

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
mapping eth0
script grep
map eth0

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

iface eth1 inet



auto eth0

That file looks ok,
What does

ifconfig

give you?

I'll try to reply, but I am in the process of moving right now, so I might not be back for some time.
