If you contact addtron and get a driver disk for that card they supply
a rtl8139 driver for the card. (old version, go for a new one) That
is probably something you already have on your machine.

Linuxconf (get a updatet version if possible, nicer GUI) and get in to

Client Task
Basic host information
Hostname (set it)
adaptor 1 (set it)
There set something like this (vlb-486 is my 'hostname' with the

The 'F2 Lists Combo Choices' should have given you the rtl8139 as a

But just tested on a machine (Redhat 5.1 and it was not there as an
option)
Fill it in anyway and test.

3Com is very expensive. why choose a $80 3com card vs. a $15 card or a
$40 card?
what's the difference between them? does it last longer? faster?
reliable?

I'm using it now when I boot Linux. My only problem is that there is some
kind of conflict between it and my soundcard (Genius Sound Maker) which I
haven't resolved yet. The upshot is no sound but I get onto the network
ok.
(If anyone knows how to resolve this particular pnp problem - not pnp
problems _in general_ but this specific one -, boy, I'd welcome a hand, by
direct mail.)

this isn't a forsale group, so I'll give it some content.
24 port hubs are down to a little over $10/port nowadays.
hubs are fairly unpleasant devices, since they impose half-duplex.
switches, even lots of small switches, are often a better idea.
you start out with greater bandwidth (100 Mb either way), and
throughput degrades a lot slower than with a shared media.
these days, 10/100 switches are down around $700 for 24p,
or only $20-30 for small switches.

1. 10/100 cards still cost more than 10-only cards.
2. Performance. All modern PC 10 Mbps Network Interface Controllers (NICs)
can saturate the wire sending, or receive at the full rate without dropping
any packets. Some of them will use up a third of your CPU time doing it.
ISA cards have to do that, because the ISA bus is only about three times
faster than 10 Mbps Ethernet. On a client workstation, this may not matter.
3. Noise margin. Badly designed no-name cards from Taiwan in plain white
boxes may have a perfectly good controller chip, but they don't provide it
a stable power supply and it barely works. A card like that may work fine
until you upgrade the video card in the next slot, and then it starts
dropping half the packets or worse, because the few extra millivolts of
power supply noise pushed it over the line.
4. Radio Emissions. Cheap cards may have fudged the FCC B or CISPR 22 B
(CE Mark) tests, and they use poorly controlled magnetics, and they don't
qualify for the huge OEM customers who move most of the NICs these
days who have to comply with these things. If you don't mind not getting
a clear TV picture within ten meters of the card, this could be a bargain.
5. IEEE signalling compliance. You might get lucky and get a $19 NIC
that can send and receive over the full cable length, with the cable draped
over fluorescent light fixtures and run next to power lines. The $98 NIC
is tested at the factory for its ability to do that. The $19 NIC comes
from a factory where they wouldn't know how to perform that test
if they wanted to. Or it's a closeout deal on a good product, grab it.
6. Safety. Ethernet cables are supposed to be isolated from the PC chassis.
The isolation is supposed to withstand 1500 volts. 3Com tests to 2500.
This matters on a large network in office cubes, when the night cleaning
crew comes in and plugs a 5 HP floor polisher into your PC's outlet strip,
and when they turn it on your PC sees a 1200 volt surge relative to
ground and the ethernet cable. If your $19 NIC only has 400 volt
isolation, your PC fries, or maybe it just loses data.
It also matters if your Ethernet runs from one floor to another.

there is a control panel, it just looks different than the
windows version.
to acces this, login as root, and type
control-panel
if that doesn't work, the the abosolute path (under rh 6.0) is
/usr/bin/control-panel
there you can set up everything.
if you want to setup your network via the network scripts, they
are located (again, under rh 6.0) in
/etc/sysconfig/ and
/etc/sysconfig/network-scripts/
the important files are network (in which you setup your
hostname, gateway, domain-name etc...
and in network-scripts/ the file
ifcfg-eth0 which contains all of the arguments to pass to
ifconfig on bootup
(like the device, the ip address, the netmask, the network, the
broadcast address, weather to execute this script at boottime
and what-not)
hope this helps.

Hi,
One of the first commands (if not the first) in those scripts is to
source /etc/rc.d/init.d/functions which defines the "daemon" function.

Subject: Please help: client Win98 -> Server RedHat 5.2
Date: Wed, 11 Aug 1999 23:25:29 -0700
Hi,
Can someone please help:
1. I am trying to connect Win98 (client) box and
RedHat 5.2 (server) through Ethernet crossed cable
(no hub).
I know that I have to make the file Hosts under Win98
with IP addresses from /etc/hosts file under Linux.
What settings has to be entered under
Contol Panel -> Networking for Win98?
2. I am having hard times trying to follow the book "Apache - the
Definitive guide" (II edition), maybe partially due to the fact
that the authors used FreeBSD. For example, the /etc/hosts file
is:
127.0.0.1 localhost localhost.localdomain
192.168.123.2 www.butterthlies.com
192.168.123.2 sales.butterthlies.com
192.168.123.3 sales-IP.butterthlies.com
192.168.124.1 www.faraway.com
What I see in netcfg is :
127.0.0.1 localhost localhost.localdomain
192.168.123.2 sales.butterthlies.com
192.168.123.2 sales.butterthlies.com
192.168.123.3 sales-IP.butterthlies.com
192.168.124.1 www.faraway.com
And in linuxconf I see :
127.0.0.1 localhost localhost.localdomain
192.168.123.3 sales-IP.butterthlies.com
192.168.123.2 sales.butterthlies.com

marketing. the 98 is probably some gilded card with "3com" or "intel"
on it. the $15 is probably a noname with a ne2k clone or similar.
in most cases, a $15 card is going to work very nicely for you;
in some cases, you should trade up to a $25 tulip/tulipclone.
there's _ZERO_ reason to buy an overpriced 3com/etc.

Hi
I'm having some problem trying to get ipchains to redirect traffic destined for
port 80 to port 8080 on a proxy machine for transparent proxying.
Here's what I've tried:
ipchains -A input -p TCP -d 127.0.0.1/32 www -j ACCEPT
ipchains -A input -p TCP -d 1.2.3.4/32 www -j ACCEPT
ipchains -A input -p TCP -d 0/0 www -j REDIRECT 8080
ipchains -L
Chain input (policy ACCEPT):
target prot opt source destination ports
ACCEPT tcp ------ anywhere localhost any -> www
ACCEPT tcp ------ anywhere some.server.com any -> www
REDIRECT tcp ------ anywhere anywhere any -> www => webcache
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):
Running Linux 2.2.10 with (I think) all necessary modules compiled.
If I try and telnet to port 80 on localhost or a client machine I get
connection refused - port 8080 is open and accepting connections.
I've obviously missed something along the way, and I've read FAQ's and howto's
to the point of going barmy with no solution.
Would someone mind pointing me in the right direction?
