Debian IPtables insmod

Hi all,
I just installed Debian stable distro. I ran an apt-get update and upgrade.
I then configured my pppoe using roaring penguin.

I want to use my linux box as a gateway and router for my internal network.

I am trying to use iptables. I just wanted to get the most basic routing
configured so my roommates can stay on the internet will I work on the
firewall. So, I entered the following command at the terminal as root.

iptables -t nat -A POSTROUTING -s 192.168.0.0/255.255.255.0 -j MASQUERADE

and I get:

can't initialize iptables table `nat': iptables who? (do you need to
insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Any ideas? I just updated. I am confused.

Please help me.

Thanks for your time.

Debian stable installs a 2.2 kernel by default unless you tell it otherwise.
Upgrade to a 2.4 kernel with

apt-get install kernel-image-2.4.18-1-xxx

where "xxx" is the processor class you're using. Use

apt-cache search kernel-image

for a list of all possible images

If you don't want to upgrade the kernel use ipchains instead.

upgraded to kernel-image-2.4.18-1-K7 now my network card will not
initialize. System says that eth0 is not installed. Is there any way to
rollback drivers? Are there default drivers included in the kernel?

Thanks.

It says that the device is not found. I tried to do: modprobe 3c59x. insmod
failed.

All help thanks.

Please don't top post.

I need a lot more information. Exactly how did you install the kernel image?
Are you using LILO or GRUB (my guess would be LILO for Debian but I want to
make sure)? This is a stupid question but you really do have a K7
processor? What does "lspci -v" say about you card? What's the output from
"uname -a"? Assuming LILO, did you add "initrd=/initrd.img"
to /etc/lilo.conf and re-run /sbin/lilo (if you didn't the kernel shouldn't
boot but it's worth checking)? Run dmesg and look for lines that start with
"eth0". What does it say there?

You can't "rollback" drivers (in the MS sense) because drivers are built for
that kernel and that kernel only. The setup should've added this
to /etc/lilo.conf so you can boot the old kernel again:

image=/vmlinuz.old
label=LinuxOLD
read-only
optional

If it didn't, make sure /vmlinuz.old exists and is symlinked to
boot/vmlinuz-2.2.20 (or whatever 2.2 kernel you have), add the above stanza
to the end of /etc/lilo.conf and run /sbin/lilo.

Any other error?

I have done some more reading. I used apt-get install kernel-image to
upgrade the kernel. However, I did not install the headers or the
pcmcia-modules for the k7. I am currently reading about how to properly
upgrade a kernel. Thanks for the help.

Do you know a good tutorial for upgrading the kernel via the apt-get without
compiling the source manually? I am confused on the order of operations.
When to download the pcmcia and headers?

thanks.

The procedure I use for upgrading a 2.2 to 2.4 kernel on my Debian systems
is this (assuming I'm upgrading an Athlon or Duron based system):

apt-get install kernel-image-2.4.18-1-k7

Then I edit /etc/lilo.conf to read:

image=/vmlinuz
label=Debian
initrd=/initrd.img
read-only

image=/vmlinuz.old
label=Rescue
read-only
optional

and make sure the vmlinuz, vmlinuz.old and initrd.img symlinks in / point to
the correct files in boot:

vmlinuz -> boot/vmlinuz-2.4.18-1-k7
initrd.img -> /boot/initrd.img-2.4.18-1-k7
vmlinuz.old -> boot/vmlinuz-2.2.20

And that's it. Everything just works after that. You only need the pcmcia
modules package if you're using a laptop. You don't need the source or
headers packages at all.

I don't know what else to say except please don't top post.

I apologize. Won't top post anymore.
