Hello guys,

I am very new in Linux and I am not confortable with Linux Prompt (text mode), so I usually use the X-Window.

I used to work with Red Hat 9.0 and everything was perfect. Now I did an upgrade in my Linux to Fedora Core 1 and I am having some problems with my Internet, in fact I can't connect to the Internet.

Here is what is happening: I installed Fedora Core 1 and I have no problem during the instalation, everything was successfull. However, when I reboot the machine, the system coudn't bring the Ethernet up. This problem occurs each time the computer starts or reboot.

When I saw the problem above I tryied to Active the Ethernet (logged as root) from inside the X-Window, but I fail when trying to Active the Ethernet.

What can I do to solve this problem?? I hope you can help me... Please, give me very detailed instructions (if you can...).

Thank you very much!!!


Obs.: Here is the messages that I receive:

* Activating network device eth0, please wait...

Determining IP information for eth0...

SIOCSIFFLAGS: Device or resourse busy
SIOCSIFFLAGS: Device or resourse busy
failed

* Bringing up interface eth0:
SIOCSIFFLAGS: Device or resourse busy
SIOCSIFFLAGS: Device or resourse busy
failed

su to root in a shell and try bring the network down, then up again... doubt it'll help much but who knows...

ifconfig eth0 down

ifconfig eth0 up

then run pump --interface eth0 to get an IP (if RH still use pump that is) if not try dhclient eth0

cg

Didn't work....

Another suggestions??

Are you set up for DHCP or static? Could something as easy as this be preventing it? If static and have another same ip address that could be the problem.

My DHCP is set up... but I have already tried with an static IP and it didn't work as well...

Here is the results of some configuration files:

/etc/sysconfig/network
NETWORKIN=yes
HOSTNAME=localhost.localdomain

/etc/sysconfig/network-scripts/ifcfg-eth0
#Realtek | RTL-8139/8139C/8139C+
DEVICE=eth0
BOOTPROTO=dhcp
HWADD=00:60:67:06:24:55
onBOOT=yes
TYPE=Ethernet
DHCP_HOSTNAME=localhost.localdomain
USERCTL=yes
PEERDNS=no

/etc/modules.conf
alias eth0 8139too
alias usb-controller usb-ohci
alias usb-controller1 ehci-hcd
alias souund-slot-emu10k1

ping -c1 localhost everything is fine... OK!!!

ifconfig eth0 up
SIOCSIFFLAGS: Device or resource busy


What can I do to solve this problem??
Please help me...

It's really easy... you just need to disable "Plug and play OS" in BIOS.
I experienced exactly the same problems as you, but this little trick seems to do the job...

If that doesn't work, perhaps you just need to bring up your driver :

"modprobe 8139too", perhaps in a script somewhere.

It's true... it's really easy!!!

Everything was perfect (network and soundcard configuration was OK). I hadn't had to change anything.

The only thing I had to do was disable "Plug N' Play OS" in the BIOS. When I did this both (network and soundcard) worked perfectly well!!!

Thank you all guys!!!

Hrm, when I checked the BIOS, Plug and Play O/S was already disabled....any help?

I'm using Fedora, btw...thanks!
