[H-GEN] Ip Masquarade Module Install

[Ross Camm]

Hello all

As a linux newbie, I have a number of problems, that I hope some of you
have been thru before.

I installed Redhat 4.2 ( Kernel 2.0.30 ) successfully. Got my linux box on
my local lan. Configured my serial/modem port successfully. I even managed
to configure pppd without a hitch. I was feelin good.

Next: IP Masquarading, so my lan could access the net without haveing to
use 3rd party software tacked onto a winnt machine.

I have read all the documentation on masquareding and modules I can find.
It sounds so simple. make config; make dep; make zImage ;make modules ;make
modules_install.

I did'nt know so much could go wrong !

In /usr/src/linux the only thing there is the include directory.
so I rpm kernel-2.0.30-2.src.rpm

I cannot find where this is installed to as the /usr/src/linux directory
does't change. No amount of looking would locate it.

So I grabbed linux-2.0.30.tar.gz and unpacked it into /usr/src/linux ( I
created a new directory and linked /usr/src/linux to it, so to not
overwrite the existing /usr/src/linux/include files. )

I then did a make config, saying that I wanted the ip_masquarading compiled
directly into the kernel. then make dep; make clean; make zImage; make
modules; make modules_install. All make's ran without error.

I then placed the following lines in rc.local

/sbin/depmod -a
/sbin/modprobe ip_masq_ftp
/sbin/modprobe ip_masq_raudio
/sbin/modprobe ip_masq_vdolive
/sbin/modprobe ip_masq_app
/sbin/modprobe ip_masq_irc

as per the ip_masquarade mini howto.


I then placed the file /usr/src/linux/arch/i386/boot/compressed/vmlinux in
the /boot and changed the link for vmlinuz to point to it.

Nothing changed. So i backed up the file /boot/vmlinuz-2.0.30 and renamed
vmlinux to vmlinuz-2.0.30, and pointed the link vmlinuz back to
/boot/vmlinuz-2.0.30.
Wouldn't boot.

Since I don't remember redhat asking me if I wanted a floppy boot disk made
afer it installed, I made a boot disk from bare.i, as I only have ide disks.

I then tried the file /usr/src/linux/arch/i386/boot/Zimage, renaming it
/boot/vmlinuz-2.0.30.

My new kernel booted, but heaps of erors when loading modules, all
"undefined" errors.

I then rebooted with the floppy again, and changed back everything I had
done in /boot, ie renaming my backup of the original vmlinuz-2.0.30 to
/boot/vmlinuz-2.0.30. The link boot/vmlinuz is still pointing to
/boot/vmlinuz-2.0.30.

When I reboot now, lilo comes up with Invalid Compressed Format (err=1),
System Halted.

I even put a copy of the original vmlinuz-2.0.30 on another machine as a
backup, but trying this file still gets the above lilo error.!!!

So from floating high to backto earth. I now can't even run my linux box
without booting from a floppy, and I'm still a long way from getting these
modules working for ip masquarading, although I have verified the the
ip_masq*.o files are in the /lib/modules/2.0.30/ipv4 directory.

I someone has the time to set me right on what I have done incorrectly, it
would be appreciated.
