Compile Kernel 2.6 under Debian Sarge

[falko]

Did you enable iptables during

make menuconfig

?

[ikkem]

hi....
yes I did enable iptables at first I thought I overlooked it but it is enabled....

[falko]

There must be a config file for your new kernel in the /boot directory. What's the output of

grep -i iptables /boot/kernel_config

?

hi....

the output is:

# grep -i iptables /boot/config-2.6.20.1-raysun3
CONFIG_IP_NF_IPTABLES=y
CONFIG_IP6_NF_IPTABLES=m

this time I got it working I did not make a symlink to linux instead I cd into /usr/src/linux-2.6.20.1 and I followed your how to
at my first and second attempt the system kept hanging on boottime and after it booted I could not connect to the net...
thanks for reacting....

I am not able to run shorewall anymore.
Do I have to compile iptables against the new kernel? part of the output of shorewall show capabilities:

# shorewall show capabilities
NAT: Not available
Packet Mangling: Not available

Looked on google/clusty but I could not find a how to compile iptables against a kernel for debian/ubuntu....

thanks in advance....

[falko]

Did you use an old, working kernel configuration for configuring your new kernel? Or did you configure your new kernel from scratch?

[ikkem]

Hi....
I used an old working kernel configuration I used the 2.6.8....configuration and then I enabled xtables... during menuconfig...

[falko]

What's the output of

which iptables

and

modprobe iptables

?

[ikkem]

the out is:

# which iptables
/usr/local/sbin/iptables

# modprobe iptables
FATAL: Module iptables not found.

I am trying to compile iptables against the kernel I installed iptables-1.3.7 now I am going to compile the kernel hopefully it will work
is there a debian/ubuntu way for this?
thanks in advance....

I finally got it working I compiled iptables against the kernel(2.6.20.3)....
here is the how to:

to patch the kernel you will need to download iptables and patch-o-matic

apt-get remove iptables ipchains --purge

cd /usr/src
iptables source - wget -c http://ftp.netfilter.org/pub/iptables/iptables-1.3.7.tar.bz2
patch-o-matic - wget -c http://ftp.netfilter.org/pub/patch-o-matic-ng/snapshot/patch-o-matic-ng-20070322.tar.bz2
Linux kernel source - wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.3.tar.bz2

unpack the downloaded files:

tar xjf patch-o-matic-ng-20070322.tar.bz2 
tar xjf  iptables-1.3.7.tar.bz2
tar xjf linux-2.6.20.3.tar.bz2

First you need to run the make menuconfig command to
preconfigure the kernel otherwise *PATCHING WILL FAIL* change into the
linux-2.6.20.3 directory and run the make menuconfig command

apt-get install kernel-package libncurses5-dev fakeroot wget bzip2 build-essential udev
cd /usr/src/linux-2.6.20.3
make clean && make mrproper
cp /boot/config-`uname -r` ./.config
make menuconfig

exit and save the config file. Now you will need to go into the patch-o-matic directory

cd /usr/src/patch-o-matic-ng-20070322
# KERNEL_DIR=/usr/src/linux-2.6.20.3 ./runme extras

Once you issue that command you will be prompt with the following

Hey! IPTABLES_DIR is not set.
Where is your iptables source code directory? [/usr/src/iptables]/usr/src/iptables-1.3.7

Once that is done you will be prompt for which patches you would like to apply, they also give you a little description on
what each patch does.

Once you have finished selecting which patches you want installed you will need to compile your iptables so you will
need to do the following in the iptables source directory.

cd /usr/src/iptables-1.3.7
make KERNEL_DIR=/usr/src/linux-2.6.20.3
make install KERNEL_DIR=/usr/src/linux-2.6.20.3
make clean

your iptables have been compiled now you can start compiling your kernel so you can issue the following in the kernel source directory

cd /usr/src/linux-2.6.20.3
make-kpkg clean
make-kpkg --initrd kernel_image kernel_headers

after the kernel build the kernel can be found in the /usr/src directory

cd /usr/src
dpkg -i *deb

Create A Ramdisk

apt-get install libhtml-template-perl libparse-recdescent-perl
cd /tmp
wget http://downloads.howtoforge.com/files/yaird_0.0.12-8bpo1_i386.deb
dpkg -i yaird_0.0.12-8bpo1_i386.deb

nano -w /boot/config-2.6.20.3-raysun1
[....]
# CONFIG_DEFCONFIG_LIST="/lib/modules/$UNAME_RELEASE/.config"
[....]

create ramdisk

mkinitrd.yaird -o /boot/initrd.img-2.6.20.3-raysun1 2.6.20.3-raysun1

update grub

 update-grub

reboot system

shutdown -r now

hope it helps....
