Help me, Ethernet does not work in Linux
 

Hi everybody,

My board has
CPU: MPC8360E
Boot code version: u-boot-1.3.2
linux kernel version: linux-2.6.22(with updated patches).

My problem is:

In kernel, I am able to ping only my board, but when i try to ping a host system in LAN,it fails!

EXPLANATION:
Using bootm cmd,I loaded
kernel image: uImage,
ramdisk image:rootfs.ext2.gz.uboot taken from MPC8360E_PB_K26_20071012-LTIB.iso
and fdtfile.

From this, I concluded network card is ok.After bootm cmd,I got the console for Kernel.

Next I doubted Ethernet card, to confirm I executed the below commands and confirmed Ethernet card is working fine.

- But Network configuration is Ok.
- And Network card is OK.( eth0: Micrel KSZ8041TL PHY ).

But really, phy can't connect to outside network. I am able to ping to my board ip address, but when i try to ping a host in LAN fails!

What could be the problem here? Am I missing some configuration?

There's too much information here, but some things are missing.

First, what kind of internet connection do you have?--ie DSL, Cable modem, etc.?
Do you have a router?
Static IP or DHCP?

If eth0 shows in ifconfig, and "ifconfig up" works, then the driver for the card is OK.

You don't mention setting the IP address or using DHCP. If you have DHCP, you have to issue dhcpcd or dhclient to connect.

Have you tried setting things up with the GUI tools in your distro?

Do you have a default route? Without it you won't be able to see beyond your local ip block.

Yeah, default route is set. Still i am not able to ping other than my system.

There is no DHCP to set ip address, it is static.

I asked you several questions---we can't help you if you don't provide complete information.

waaaaaaa......
thank you all here,for that I met the same problem with subhashini.s
