Re: Update - Re: Weird Network Card problems - 2

[Ajit Warrier <unixajit yahoo com>]

I did one better. I removed the eth0 card from the
machine and removed the card from the network
configuration tool. This is only card in the laptop.
Then rebooted.

This removed all entries from the routing table except
for the entry for lo.

Then shutdown and re-inserted the card. During
startup, it once again did *not* detect the card. I
added eth0 as a DC clone from the network
configuration tool. I checked that the card came up
and that the module for tulip was loaded.

The routing table generated was exactly the same - one
entry for the default gateway set correctly, one for
lo and one for the network. Now, as far as I know, the
entry for the local network should have the eth0 IP
address as the gateway. Am I correct here? This is how
I see the routing table in other machines.

At any rate, I can ping the IP of eth0. Cannot ping
any other IPs in the internal network. And I still do
get a different MAC address than when I am in Win98 on
the same machine. I know that each card in the world
has a unique MAC address and that it is not possible
for a card to have different MAC's in different OS's,
but it *is* nevertheless happening. 

Could it be that eth0 is only a virtual adapter (the
physical adapter not getting detected at all) and so
it can ping itself and nothing else? Because in dmesg
I get the message -

eth0: Digital DS21143 Tulip rev 48 at 0xc48e0000,
EEPROM not present, 00:4c:69:6e:75:79, IRQ 11

Any ideas? In case it helps, I can send a detailed
document showing my network, IPs etc and any other
file that may help, as attachement. Just say the word
- I am desperate here!

Thanks for your time guys.
