Hi gurus,
I am facing some problems with my network adapter. I would give a full
description of the situation.
I have an onboard LAN card (Intel EtherExpress/1000, its a gigabit
ethernet controller) on a Intel Xeon processor 3.06Ghz. I am running
Rh9 (2.4.20-8 kernel). The problem is that though the eth0 interface
comes up, still I cannot even ping to other machines. I would give a
detailed view of my configuration files:
/////////////////START OF CONFIG FILES AND OTHER SYMPTOMS//////////

# that require network functionality will fail.

/////////////////END OF CONFIG FILES AND OTHER SYMPTOMS////////////
As you can see that I am not using DHCP. So I have tried to give a
static IP address (141.11.90.104) to it. I know it doesnt clash with
other Ip addresses since this is the same IP address that I get for
this ethernet card everytime I boot using windows XP and DHCP enabled.
I have also checked the IPs of the nameservers and they seem to be
correct. I only have one pointer to the root of the problem and that in
NETDEV WATCHDOG output with dmesg. What exactly is this ghost?? I am
unable to decipher the problem and have been held up for a week now.
The funny part is that the same configuration(with different IP add)
works with another machine(running RH9 and similar ethernet card) that
is in the same subnet.
I have also tried to use DHCP but my machine does not seem to connect
to the DHCP server, hence I tried the other option of giving static
IPs.
Please help me with this problem. Any pointers would be a great help
since I have run out of ideas...
Thanks in advance
Harry.
