Red hat 9.0
I had my linux box connected to the internet via a router that was connected
to the dsl modem.
it worked for a couple of days. Now I have no internet connection through
the linux box.

when I ifconfig in the terminal eth0 was present with no associated ip
address. lo 27.0.0.1 Mask 255.0.0.0

In the Network Configuration window

eth0 an Ethernet connection is inactive. This used to be active when the
internet worked. when I try to activate it I get the this message Titled
Cannot activate network device eth0:1! "Determining IP information for
eth01...SIOCSIFFLAGS: Cannot assign requested address SIOCSIFFLAGS: cANNOT
ASSIGN REQUESTED ADDRESS FAILED"

How can I change status of eth0 to active?

The error message doesn't mention "eth0", it talks about "eth0:1"; in
Linux, that's a second IP address to be recognized by your NIC, and
another device altogether.

As root, do a:

# tail -f /var/log/messages

in one window while you do:

# ifup eth0

in another and show us what you get.

Cheers!

We didn't catch enough "/var/log/message" traffic to be very helpful.

I can think of two more places to look:

# ls -l /etc/sysconfig/network-scripts/ifcfg-eth0*

and

# cat /etc/sysconfig/network-scripts/ifcfg-eth0*

and let us see that.

Cheers!

tommy reynolds

Having "ifcfg-eth0:1" and not having "ifcfg-eth0" is quite odd.

We are getting closer.


First, you need a space after cat:

# cat /etc/sysconfig/network-scripts/ifcfg-eth0*

Keep the faith ;-)

Thanks

this is the result

root@localhost root]# cat /etc/sysconfig/network-scripts/ifcfg-eth0*
# Please read /usr/share/doc/initscripts-*/sysconfig.txt

# for the do***entation of these parameters.

TYPE=Ethernet

USERCTL=yes

PEERDNS=yes

GATEWAY=192.168.0.1

Here is my "ifcfg-eth0" for a DHCP setup:

# Realtek|RTL-8139/8139C/8139C+
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=08:00:46:BD:1B:55
ONBOOT=yes
TYPE=Ethernet
DHCP_HOSTNAME=lexx.localdomain
USERCTL=yes
PEERDNS=yes

as a reference.

Change your "ifcfg-eth0:1" file and as root:

# ifdown eth0:1 <--- Ignore errors
# ifup eth0:1 <---

P.S.: You don't need to restart the networking service if it is
already running. We just want to reset "eth0:1".

As usual, if any error messages are captured or displayed, please let
us see them.

Cheers!

Thank you sir the problem is solved. I think it was the ifcfg-eth0:1 file

Thanks for all the help.
