I've been struggling through a new Suse 10.1 install. Actually, everything has gone well accept for my network configuration.

I'm running the following...

NIC: "HP 82562ET/EZ/GT/GZ - PRO/100 VE (LOM)
Kernel: 2.6.16.13-4

During the standard YaST install procedure, the card is detected, and seemingly correctly configures the module name to e100. I have it configured to use DHCP to acquire an address. However, during the internet connection test, it fails to get out (no IP address is obtained). The log displayed during this workflow says,

"DHCP client is already running on eth0"

1. After completing the installation, the card does appear to be working partially. The loopback interface is up and I can ping localhost.

This *does not* prove anything about the NIC - the IP stack
is smart enough to route accesses to *any* of the local IP
addresses via the loopback interface.


I've since learned that the loopback works even without a NIC card physically present...

Please verify the presence of the interface with

ifconfig -a


I'd print it here if it were easy, but you'll have to trust me that the interface is present.

Do the cable link LEDs light at the NIC and the box at
the other end?


No lights at the other end of the tunnel....

2. /var/log/messages has the following repeatedly...

"ifstatus-dhcp : eth0 dhcpd is still waiting for data
** this seems to be at odds with the log message during the internet test, no?

It seems that your interface in there, but the thingy at the
other end of the cable does not understand to serve your
DHCP requests.

3. dmesg produces the following during boot up...

"e100 : eth0 : e100_probe : addr 0xcfffe000, irq 209, MAC addr 00:17:31:A5:40:9E"
** no errors

4. lsmod lists the following for the e100 module...

"mii 5120 1 e100"
** what is mii? is this another interface that is stealing access?

MII (Media Independent Interface) is a specification for the
connection between the Ethernet protocol engine and the media
access unit inside the modern Ethernet chips. It needs to be
set up by the NIC driver to enable the medium (means CAT-5 cable)
access properly. The module is OK and necessary here.



Thanks.


7. there are no limitations (mac filtering, dhcp client limitations, etc.) in my linksys router configuration that would explain the lack of an IP address being served up.

Very possible. If the box is providing a NAT service to the
internal network, it should provide DHCP also.


I was thinking about trying a newer version of the e100 driver, but there is nothing in the documentation that indicates the current one would not work. Furthermore, Intel has nothing on their support site to help troubleshoot this.

Thanks.
