Re: Configuring ethernet tap on a new Debian install

Wolodja -- the output from the lspci command is

00:19.0 Ethernet controller [0200]: Intel Corporation Device [8086:10f0]
(rev 06)

Papul -- the kernel is 2.6.26-2-amd64.

Sounds like I should just go ahead and update my kernel, and that should
solve some other, unrelated and less critical issues. I'll try that tonight
(right now it's 7:15 AM local time and I'm off to work).

Thanks for the suggestions,

I just finished building a new computer around the Intel DH55TC
motherboard. I would like to configure the computer to use DHCP via its
built-in ethernet tap, but the ethernet was not detected or configured on
installation. There is no eth0 entry in /etc/network/interfaces, no eth0
entry displayed by ifconfig, no dhcpd.conf file is present, and dhcpd is not
listed in inetd.conf.

I suspect that the problem is that the motherboard is so new that it's not
supported in the 2.6.26 version of the kernel: when I looked at the Intel
webpage relevant to the board,
http://www.intel.com/support/motherboards/desktop/dh55tc/sb/CS-031186.htm,
it suggests that a LAN driver may be needed for Linux, and I infer from
their table of information that this is more likely to be the case for
kernel versions prior to about 2.6.31.

So what I think I need to do is the following:

1. Download and install the LAN driver
2. Manually configure the system so that it recognizes the Ethernet tap
3. Add eth0 to /etc/network/interfaces
4. add a dhcpd.conf file
5. add dhcpd to inetd.conf.

Does that sound about right, or is the reality simpler / less simple than
that?

Assuming I've got it right: how do I accomplish step 2?

Thanks in advance,
