Gentlemen,

Thank you for your replies.  Since the the URL I posted in my original email
apparently is not working, I will recap what I have done for my system.

1)  Completed a successful build of CLFS for the 586 architecture using this
guide: http://cross-lfs.org/files/BOOK/1.0.0/CLFS-1.0.0-x86.html

2)  Applied certain BLFS extensions to my CLFS build.  The one that is
relevant to DHCP issue can be referenced here:
http://www.linuxfromscratch.org/blfs/view/stable/connect/dhcp.html

3)  Thanks to some wonderful help I received a couple days ago, I installed
net-tools-1.60:
http://www.linuxfromscratch.org/blfs/view/stable/basicnet/net-tools.html

I have installed DHCP-3.05 so that I could have access to 'dhclient'.  On a
separate incarnation of my CLFS system, I tried using DHCPCD-2.0.8.  In both
cases, I was unable to obtain a DHCP IP lease from my router.

My router is working fine, I have tested it with other systems, and I have
tested the CAT-5 cable I am using to connect my CLFS system.

I have verified that NIC chip-set on CLFS system is functioning properly (I
tested previously with Fedora Core 5).

Here are the outputs I received when issuing various commands under the
CLFS:

When I run "lspci | grep -i ethernet":
00:12.0 Ethernet controller: Intel Corporation 8255xER/82551IT Fast Ethernet
Controller (rev 10)

When I run "dmesg | grep eth0":
eth0: OEM i82557/i82558 10/100 Ethernet, 00:30:59:02:42:EA, IRQ 5.

When I run "lsmod":
Module             Size  Used by
eepro100          23824  0
mii                4224  1 eepro100
evdev              6912  0
apm               15468  0
rtc                8628  0

I have tried to configure the eth0 interface manually, issuing the following
command:
ifconfig eth0 192.168.1.104 netmask 255.255.255.0 broadcast 192.168.1.255 up

However, when I attempt to ping my router (at 192.168.1.1), I receive
messages that the "Destination Host (is) Unreachable".

Ultimately, my system requires DHCP support.  I cannot use/depend on a
static IP setup.  Similar systems to which I am building will be shipped
across the World to various clients who are running their own networks (or
maybe none at all), and for which I have no control over.  If they do not
support DHCP, well then I will have to cross that bridge when the time
comes.

I can testify that I am not a networking guru, but I do know enough to
configure my router and setup my own little LAN in my home.  There is
nothing wrong with a h/w.   For the s/w, I followed the instructions in the
CLFS guide and the instructions within the BLFS guide.  I have enabled or
"moduled" the ying-yang of pretty much every network option in the Kernel
configuration (which is overkill, but...).  My network device is detected,
the appropriate kernel module is loaded, ifconfig (from net-tools) seems to
be able to configure the eth0 interface, however I cannot even ping my
router at 192.168.1.1.

I do have a question about /etc/resolv.conf with DHCP.  The CLFS guide
mentions about setting it up as appropriate for one's local area network.
In my case, I have the file empty because I knew I was going to use DHCP.
Was this a bad choice?  Or should I insert "search localdomain"?

As for iptables, firewalls, etc, if it is something that is not discussed in
the CLFS or BLFS sections I followed, then I probably do not have it
setup/configured/installed on my system.  If you have any advice, concerning
these items, please be explicit with your instructions.

Anyhow, here's the correct URL at LinuxQuestions.org:
