Hi,
Thank you for replying.
Yes, I can link up fine when doing peer to peer communication. I’ve used ethtool utility to verify that the port is linked up. However, the IP address keeps disappearing after a few seconds. The problem looks like the following below.
The following showed that I’ve assigned 192.168.0.12 to eth26.
root@user:/home/user# ifconfig eth26 192.168.0.12
root@user:/home/user# ifconfig eth26
eth26 Link encap:Ethernet HWaddr 00:1e:67:d7:01:59
inet addr:192.168.0.12 Bcast:192.168.0.255 Mask:255.255.255.0

root@user:/home/user#
At this point, it was able to ping to 192.168.0.1 for a few seconds and it starts to display “Destination Host Unreachable” once the IP address is lost.
64 bytes from 192.168.0.12: icmp_req=20888 ttl=64 time=0.004 ms

I hit ctrl + c and entered ifconfig eth26. Notice the IP address assigned to eth26 has disappeared.

The problem keeps recurring even after I assign it with a different IP address. I’ve swapped the harddrive and CPU but the problem still persist. I do not see the problem when I use the harddrive and CPU with a different motherboard.
Thanks,
