This is a tutorial to compile kernel 2.6.11.12 with grsecurity. Works cool specially with exec logging you can trace just any minor activity on your server. Here are the commands I used for the compilation :


cd /usr/local/src/
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.5.tar.bz2
wget http://grsecurity.net/grsecurity-2.1.11-2.6.24.5-200804211829.patch.gz
tar xvfj linux-2.6.24.5.tar.bz2
gunzip grsecurity-2.1.11-2.6.24.5-200804211829.patch.gz
patch -p0 < grsecurity-2.1.11-2.6.24.5-200804211829.patch.gz
cd linux-2.6.24.5
cp /boot/config-'uname -r' .config
make menuconfig
make 
make modules_install
make install
grubby --bootloader-probe
pico /etc/grub.conf
grub-install /dev/hda
reboot

  Try at your own risk :D . Best of luck.

The new kernel and new patch is out. I would be updating this tutorial soon :)
