I just installed Redhat 5.2 and linux doesn't see my ethernet
card. It's an Intel Pro/100 PCI, but the problem is that I don't know
what I/O range the card is using. I know it's using IRQ 9, but linux
wants both an I/O and an IRQ. Is there some kind of linux driver
specific to this type fo card?! Any help appreciated, thanks!

THANK YOU! This post solved 75% of the problem I was having ... even
if I still don't understand why it works through a "normal" connection
and just not through a MASQ connection. I just changed the IMG tags
to FQDN (absolute) references instead of the indirect (?) ones I was
using.
Now, just the large graphic ("The Kids") doesn't work. It is a FQDN
reference, I really don't see anything wrong with it BUT it still just
loads the top 5% (about) then just sits ther ... stalled I guess. It
just never finishes.
The proxy server seems rather extreme ... I hope there are some other
solutions. One which addresses the "indirect" image reference would
make me feel better.
The web page in question is in my signature.
Thanks again for the post!

Hi Patrick,

You probably get assigned a IP number dynamicly by dial-up. If you run
kernel 2.0.36 just do:
echo 7 >/proc/sys/net/ipv4/ip_dynaddr
If you run a kernel version below but from 2.0.31 this should work too
but there is less functionality.
For kernels of the 2.1 or 2.2 series you can get a patch from
http://www-users.rwth-aachen.de/Michael.Mueller4/dynip.hmtl
which does introduce the same features as for 2.0.36 there. The features
supported from 2.0.31-35 should be allready integrated into later 2.1
kernels and all 2.2 ones.
In all cases you might want to read
/usr/src/linux/Documentation/networking/ip_dynaddr.txt (note for 2.1+
this will be modified with the patch).

1. Make sure the default gateway does not exist (let pppd create this
for you).
2. Make sure that the "other machines" have the linux box as the
gateway.
This can be tough to ferret out in both Linux and Windows, so you have
to be persistent.

There is something strange here.. the ip assigned to your computer is
24.65.228.0, correct?
That is usually wrong.. The .0 ip is normally not assigned since it
designates a subnet not an individual computer.
I believe the ip on your computer should be 24.65.228.x where x is not 0
or 1. Also, then the netmask assigned to your computer's ip above is
255.255.255.0.. this is a subnet netmask.. if should be 255.255.255.255
for your particular ip.
So check your file /etc/sysconfig/network . In there you'll find your
gateway ip and your your hostname or host ip. Also check the file
/etc/hosts. In there you might also find your host ip.
Maybe you've done this already..

There's a cool WindowMaker app called wmppp which can probe the ppp device
somehow and tell you its connect speed. It needs glibc/libc6 to compile.
Alternatively, chat can return the connect speed/options if you use REPORT
"CONNECT" in its script.

The Linux 2.0.x-kernel has support for the Specialix IO8+ card.
I think it will make the Specialix ports appear as "normal" serial

the attached terminals.

Look at the "securetty" file in the /etc/ directory and either remove or

Subject: How to setup 2 NICs in RH5.2
From: [EMAIL PROTECTED] (wlo)
Date: Thu, 04 Feb 1999 02:28:38 GMT
Hi all, I am trying to setup the second NIC card inside my linux for IP
masqurading. However, Linux can only see one card. Is there any specical
procedures that need to be done in the OS in order to do this ? The two cards
are SMC 8216 I/O: 300 IRQ :10, and SMC 8416 I/O 320 IRQ:15 running on AMD 486
133mhz. I have done the following:
1. From DOS, I can run EZsetup (Diag tool) . Both cards can be detected
properly.
2. Linux only see eth0 SMC 8216 and assigned with IP add. If I take out the
8216 and leave the 8416 inside, reboot linux , it will see the 8416 card as
eth0. eth1 is just never want to show up.
3. Replaced SMC 8416 NIC with 3COM 3C509, same situation. It can be
individually regconized by Linux but eth1 will never not show up.
Is there anything that I need to do in order to get them coexist together ?
Please help ... Many thanks in advance...

Subject: trouble with Linksys ethernet card
Reply-To: [EMAIL PROTECTED]
Date: Wed, 03 Feb 1999 21:39:21 GMT
I have a system (Slackware with a 2.0.34 kernel) that is having
trouble recognizing a Linksys 16 bit ethernet card (an NE2000
compatible).
The card is set to use IRQ 5, and i/o address 0x300 through it's own
setup program. When I do a "cat /proc/interrupts", the IRQ listing
shows that IRQ 5 is not being used so there shouldn't be a conflict
problem.
In the file "rcd.modules" the line for NE2000 compatible is
uncommented; this is what I've got:
i/o=0x300 irq=5 # I added the irq=5 argument; is that the correct
way to add the IRQ number?
When booting, the system gives an error message that the "card is not
being detected by the system, so either add a line for it in
rcd.modules or comment it out completely in <some other file>" (this
is paraphrased, obviously; I'm going from memory, the linux system is
at home and I'm writing from my office computer).
On the chance that the card is defective, is there some kind of test
that can be done to check the card itself?
Any suggestions?
Thanks in advance.

It's not quite THAT easy. What you have to do is to set up the Linux box to

Check the contract with @home for legal problems with that. Otherwise, you
can use the same IP masquerading for that as you set up for your home PCs.

Most distributions are already set up that way - I have debian and the only
tree users can www to is under /var/www - if they try any other directory,
they get Access Denied.

I responded both email and to the group.

BTW, this is a very common setup. I have the same setup running now, as do
many others, ever since cable-modems came out..:)

Which means that there is a route declaration that isn't correct. You may
not be on a full class-C network (255.255.255.0) but on a subnet (like
255.255.128.0 or something).

I think you have misinterpreted the output of netstat. "netstat -nr"
shows the routing table without name resolution and in this case it's
showing that:
1) LAN 24.65.228.0 is connected to eth0
2) LAN 127.0.0.0 is connected to lo
3) the default route is to 24.65.228.1 via eth0
This all makes sense to me, provided that the ISP is using a full class-C
network.
So, I suggest checking the output of ifconfig. It should say that your ip
address is 24.65.228.x with netmask 255.255.255.0 and broadcast
24.65.228.255 if you are on a full class-C. If it's different, then your
routing table doesn't match the interface's settings or vice versa.
Hope this helps,
Luca

Subject: Suggestions for a small network
Date: Wed, 03 Feb 1999 21:34:10 -0500
I'm a Linux neophyte and need suggestions on my small 3 machine network.
I currently have a Win 98 and NT 4 server networked. When I try to
configure my RH 5.2 box, I cannot even ping the NT server. I changed the
default gateway to the NT server IP address because it is the DNS
server. I noticed on the IFCONFIG that packets were TX but errors on RX.
What should the settings be for a non-routed network? I simply used
three different IP addresses for each machine and made the apporpiate
entries in the hosts file.
Should I let the RH box do the DNS?
I'm struggling to learn this linux, but anything is better than NT.
Thank God for a K/V/M switch.
Assistance appreciated.

Yes, exactly. I far prefer to keep Samba on a machine inside the firewall. It
is safer. Also simpler to configure and upgrade if the two functions are on
separate servers.
