RE: network unreachable

[Ilocto Noel-C1395z <c1395z email mot com>]

Hi,

I can't remember it all what I have done or command.

I never edit any startup script, is the linuxconfg is a command line
command, 
I think I used this before but can't remember exactly what I have done with
it.

What I used is the GUI  linuxconf Network Configuration from "startx"  menu.
But the only thing I remember doing here is the addition of Network
Interfaces
Eth0 and assigning IP address on it. I tried to map the 127.0.0.1 IP address

to device lo (loopback) from this menu but I always received error message
something like this "can't edit"

I am at work right now, as far as I remember these are the contents of this
file.

/etc/hosts

127.0.0.1 localhost localhost.localdomain
192.168.42.7 pc1 nilocto

		For a reason I can't fathom, your loopback has a broadcast
address. Mine
		works and doesn't have one. How are you bringing this up?
Have you added
		something in a starup script that tries to start it at boot?
Have you
		chnged its settings wiht linuxconf (know to be buggy on some
things,
		especially mail)? Have you done any configuration to it at
all? What does
		/etc/hosts show?

		Try:

		        /sbin/ifconfig lo down

		After you get the OK (which you have wother problems if you
don't get it)
		type:

		        /sbin/ifconfig lo up

		As a matter of fact, you could try the last one first just
to make sure you
		get an error, then try them both, error or no.
