Hi ,
I have a Hitachi Solution engine board for which i m trying to get
the Networking.

I have built the Root file system from scratch having all the necessary
entries for Networking.
( i installed all redhat packages for building the
Root file system)

But still the Network is not up.( this i have verified by pinging from
other systems, Even arping is not working)

I have checked for the important networking scripts such as

\etc\sysconfig\network-scripts\ifcfg-eth0
\etc\sysconfig\network-scripts\ifcfg-eth1

\etc\sysconfig\networking\devices\ifcfg-eth0
\etc\sysconfig\networking\devices\ifcfg-eth1
All are fine.basically there are two interfaces in my board


Some Details:

1 . when I type ifconfig i m able to get all the information required
such as
IP address and others.

Except the Mac address
The mac address looks something like this.
00:00:00:00:ff:ff

Is it correct to have like this??

2. when i type arp i got the output like this

$ /sbin/arp

hardware address.
incomplete


3. When i tried to do arping it gets failed.


4. i checked the dmesg.

it shows something like TX error: dirty_bit bla bla.......


I feel the problem is with finding the Mac address...Please share with
me your views and suggestions.

I m a newbie in Linux networking. Thanks in advance.

Regards
SaranJothy.

Not familiar with it.

That is an indication that you are not using the correct network driver,
or that there is a hardware conflict. You might see clues looking at
the boot messages that would normally go to /var/log/messages and
/var/log/dmesg (on a Red Hat or derivative system). Hitachi doesn't have
an OUI code registered with IEEE, so I can't say what the MAC address
should be, but for certain the first six characters will not be 00:00:00:.

Yes, until you see a "reasonable" MAC address, all attempts at using the
network are useless. As this is an embedded device, have you tried the
comp.os.linux.embedded newsgroup? Have you also tried a search at
google groups?
