I just installed RedHat 7.1 and am having considerable difficulty getting connected to the Internet. I have disabled my onboard ethernet card because it was incompatible and am now using a DLink card.

It's currently part of a LAN (with a alcatel adsl speed touch home, and a linksys etherfast cable/dsl router.

When the system is booting up it does it's normal stuff but when it comes to eth0 it says:

Bringing up interface eth0:

and takes a good couple minutes and finally returns something to the effect of "assigning ip address failed"

When I type ifconfig in the terminal the eth0 doesn't show up at all. When I enter in ifconfig -a I get the following

eth0 Link encap:Ethernet HWaddr 00:50:FC:1B:96:2A
BROADCAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:14 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:11 Base address:0xd000

I also get the lo information, but I'm not sure if that's relevant so I'll leave it out for now.

I may just have the netcfg configured wrong (I'm not entirely sure what I have to assign manually, I'm using dhcp), but I'm really stuck on this and any help would be greatly appreciated (and would allow me to be rid of the evil windows forever

Thanks a lot guys

Assuming that you get your IP lease from the router and not directly from the ISP, you should be able to secure a lease with the following:

ensure that your /etc/sysconfig/network-scripts/ifcfg-eth0 file has these 3 lines

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp

Just run 'netconfig' as root and set the system for DHCP. That should set the card up properly and poll the network for a DHCP lease.

Let us know if that doesn't work.

Note: Running 'ifconfig' will only show active interfaces, the '-a' switch you added is for 'all' which includes inactive interfaces.

Other things:

- make sure you're getting a link light
- You say you are part of a LAN? Does that mean you have several machines sharing your ADSL connection? If so, then how are the other machines set up? Are they DHCP or do they have static IP addresses?

Hi there.

Where do you get the IP address for your Linux box from? Is it from your ISP?

I had the same problem when I switched from using my *cough* windows *cough* box for internet access to using a linux box.

I have a cable connection, which is very picky on which ethernet card it accepts. Basically I had to tell the ethernet card (the new one) to have the MAC address of the old card. (Don't use the old card anymore since it is only 10 MBit.)

In the ifup-eth0 file I added:

MACADDR="00.11.22.33.44.55" <- insert MAC here

to trick the cable modem into believing it was the same card.

A good place to look would be http://www.europe.redhat.com/documen...dem/index.php3

This one also has bits about DSL in it.

Hope this helps

Okay... this might help... my cable provider just moved us from static to dynamic addressing. I have trouble getting it to work in Linux. I found out that the ISP's DHCP server requires the system's hostname to be sent when requesting a lease.
You can check this by issuing "dhcpcd -h YOURHOSTNAME" using whatever name your ISP gave you.

To make that happen automatically, you need make your ifcfg file like this:

DEVICE=eth1
DHCP_HOSTNAME=YOURHOSTNAME
BOOTPROTO=DHCP
ONBOOT=YES
TYPE=Ethernet
USERCTL=no
PEERDNS=no

I moved the computer to a different Lan and altered the config files as suggested and it's working great now. Thanks for the help guys
