[SOLVED] eth0 works without configuration... ?

[quaid123]

Hello!

Magically, my internet connections works via my eth0 adapter. For Windows user this may be fine, but I actually would like to know what makes it connect.

My /etc/network/interfaces shows:

auto lo
iface lo inet loopback

auto wlan0
... doesn't work anyway ...

No eth0 mentioned here. dhcp3/dhclient.conf consists only of commented-out lines, so no eth0 here either.
In /etc/init.d I see there is this networking daemon. When I do

sudo /etc/init.d/networking stop, I see:

...
Ignoring unkown interface eth0=eth0

Gee, that magically enhanced eth0 works even if you want to shut it down...

No wonder I don't get my wlan0 working, my PC doesn't seem to care about anything I am configuring here...


EDIT: the only place I see any eth0 in is
/etc/initramfs-tools/initramfs.conf: DEVICE=eth0
is that it? It doesn't make any sense because how should it know that it should use DHCP?

/etc/network/interfaces is for manually configuring your network settings. In fact, if anything other that those two lines are in there, it screws up what is handling your networks, which is called, da da dum, NetworkManager.

Thank you, so no configure writing anymore, huh? I guess this is good

WiFi works too, but sadly the networkmanager crashes when he tries to connect via WPA2. I see that its in beta, is there an alternative?


Best regards,

I've always preferred Wicd.
