How to remove an inactive eth0

satimis · 08-17-2004, 07:31 AM

Hi folks,

FC2
(upgraded from RH8)

On starting the 'Network Configuration window'
(K_Start --> System Settings --> Network)

Code:

Profile    Status    Device   Nickname    Type
(check)    Active    ppp0     BroadBand   xDSL
(uncheck)  Inactive  eth0     eth0        Ethernet

An Inactive eth0 is always there. Deleting it did not help. On next start it came back.

BroadBand is working without problem.

Kindly advise how to remove it permanently. OR it must be there?

Hi,

If your DSL modem uses RJ45 (i.e Ethernet card), you need eth0. Else (i.e modem uses USB) you can remove it. To do that, remove your network card module and be sure that Linux doesn't load it at boot anymore.

Hi,
I found that Linux configures ehernet cards by reading their configuration files in:
/etc/sysconfig/networking/devices/ path, you well find for each ethernet card a file named like this
ifcfg-eth0
ifcfg-eth1
etc....
simply move the file for which ethernet card you don't want to known location (just in case), then restart your computer to take affect.

Hi folks,

Tks for your advice.

I have only one ethernet card (NIC) which is connected to xDSL modem with a RJ45 plug. On other Linux distro including Redhat it needs both ppp0 and eth0 to be present on the 'Network Configuration window'. I'm curious to learn whether on Fedora Core2 eth0 is not necessary and can be removed. Because even when it is inactive broadband is still connected.

$ ls /etc/sysconfig/networking/devices/
ifcfg-eth0
ifcfg-Broadband

No more, only 2 (two)

If your modem is connected via RJ45, you need eth0 'cause if eth0 is not present, it means that his driver is not present (as a matter of fact, it's driver insertion which create eth0). And If driver is not present, when your packets will arrive, NIC's IRQ will be lost and so packects

One point I don't understand why eth0 being inactive but ppp0 still working with broadband connected.

I suppose that 2 protocols of the same layer can't be active at the same time on the same device (PPP linked to ppp0 dev and Ethernet linked to eth0 but both use NIC).
