- Under KDE:
Situation # 1
KNetworkConf (in KDE ConfigCentre – Network parameters) does show
eth0 _alone_ , but it is not given any IP address (although DHCP is
the preselectioned IP detection mode); nothing changes before
detection is restarted by deactivating then reactivating the
interface in this module. Situation #2
knetworkmanager, the applet I installed to ease connection and
deconnection to the network, is as much “confused”; after KDE starts
it “runs empty” can't/won't connect to any interface for about 20
seconds, to finally systematically choose the wrong one: “usb0”
I don't know that tool and I would not trust it. But did you by chance
install the network-manager? dpkg -l network-manager will tell you.
--> Yes it is installed.
This confirms what I see under KDE:
something (what?) makes the system (which element, routine, module,
programme, package?) choose the wrong interface “usb0”.
How to solve this problem? This is the whole headache here!
My other problem is, I don't really know which other tests to carry
out to find out which setting I have to try with which programme,
routine or module or else... - before thinking of filling any bug
report for a particular package...
Please check if you have network-manager installed. You could also try
`ip addr` and the like.
--> What is `ip addr`? Can you explain?
PS Here is the contents of the first /etc/network/interfaces file
(the one generated at install)
BEGIN---
# 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
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
auto eth0
END---
I've had five versions and none worked as I wished...
Did you try commenting out allow-hotplug eth0?
--> Yes, that is gone in my present /etc/network/interfaces file.
