<div>I was thinking of IP-tables too. I know it needs some
sort of forwarding of the traffic from the TFTP server to the main

<div>My plan was to use this very out-dated machine to simply play
internet radio streams via the console given that it uses very
little energy. I like having background music in my house

<div>but I can absolutely no longer listen to any commercial radio
stations; the advertising and yackity-yack is mind-numbing...that's
an entirely different conversation! </div>

<div>I put the Debian network install disk ISO on to my USB flash

<p dir="ltr">Greetings,</p>
<p dir="ltr">With the configuration you described here you'd
probably want to look at iptables on the host machine for all of
the forwarding-fu. It's as not difficult as it sounds but it
can get somewhat confusing. I've never personally attempted
it with a direct connection to the client but it *shouldn't* be
much different.</p>
<p dir="ltr">It is a tad overkill in your situation but If you
still want to give it a shot I'd be happy to help you try to get it
working once I am back at a keyboard (software keyboards are an

go let me know.</p>

<div dir="ltr">Well, it's one of those things where I don't "have"
to use a PXE boot. But I just wanted to see if I could figure
out how to do it using this machine:
<div><br></div>
<div><a href="http://www.fic.com.tw/product/iona603.aspx" target="_blank">http://www.fic.com.tw/product/iona603.aspx</a>
obviously, no optical drive. I was able to squeeze a
60gigabyte laptop IDE drive into it though!<br>
<div><br></div>
<div>All of the stuff I've been finding online is for configuring
the client machine (target of install) with it being a part of the
regular network, i.e.-attached</div>
<div>to the router like the other machines, including the one with
the boot image files and such.</div>
<div><br></div>
<div>My configuration was to have the client machine directly
attached to the host machine (via eth0) which was then
attached to the router for web access</div>
<div>(via eth1). The host machine has two NICs built onto the
motherboard.</div>
<div><br></div>
<div>Unfortunately, with my limited networking knowledge (enough to
get myself into trouble) I was not able to figure out how to use
the host machine not only as</div>
<div>the PXE boot host with the install files, but also the bridge
to allow the client doing the Debian install to have internet
access to complete the installation via</div>
<div>a mirror.</div>
<div><br></div>
<div>I ended up just using a Debian installation ISO on a 1
gigabyte USB flash memory stick and ran the network cable
direct to the router. So far, so good. If I</div>
<div>can get basic Debian install on the AMD Geode, I want to try
building a cut-down, streamlined kernel for it; again, just to see
if I can get it to work.</div>
<div><br></div>
<div>I didn't want to get too carried away with my workstation
machine (host) as I mainly use it to edit video/audio; no telling
what I might have done had I started trying to</div>
<div>set up a mirror on that machine for the client to
use....eek.</div>
<div><br></div>
<div>Thanks for the suggestions, though. I appreciate the
input!</div>

Greetings everyone,<br>

**initial disclaimer; new to this stuff, not good with
networking**<br>

I was able to get a PXE boot started for a Debian installation on
an AMD Geode machine. The installer begins fine and it gets
to the point of asking for a mirror to use for installation
packages. I select the main Debian mirror. This is where it
fails as it seems unable to access the internet. Alt-F4 shows
messages on the client ending with:<br>

Do you have to do a PXE boot?<br>
<br>
Can you boot an ISO image and install from that?<br>
<br>
After the install then do the final setup for what you
need.<span><font color="#888888"><br>
