Installation

Abstract:

• download patch; patch and reboot kernel
• download source distribution
  tar -zxvf koctopus-version.tar.bz
  ./configure
  make
  su -c "make install
  

Kernel Patch

Download the kernel patch that match your kernelversion:

uname -r
# e.g. 2.6.12-rc4-mm1

You should take patch 2.6.12-rc4-mm1-koctopus.patch.diff

Patch you kernel

cd /usr/src/linux
patch -p1 ../KERNEL-VERSION-kocotpus.patch.diff

Configure you kernel:

make menuconfig
# under drivers->net select kocotpus
# if you wan't to debug the kocotpus you can also select the debug option
make
make modules_install
cp arch/i386/boot/bzImage /boot/`uname -r`-koctopus
reboot

Fine! If you see a linux booting message like
koctopus network performance framework
everything works fine and you did a goof job! ;-)

Errors, Problems, ...

If you find some errors, here are some generic pointers:

• make sure you had a valid linux source pointer:

  
  ls -al /lib/modules/`uname -r`/build
  # e.g. /lib/modules/2.6.12-rc4-mm1/build -> /usr/src/linux-2.6.12-rc4-mm1
  

• your kernel boot messages MUST display somehting like this this

  
  ...
  test
  test
  test
  ...
  

• your kernel version MUST higher or equal then 2.6 (uname -r)
