First, download the Bering kernel configuration file in the /usr/src/linux directory and rename it .config.

Then do the following:

cd /usr/src/linux
make dep
cd /usr/src/freeswan-1.99
make menugo (or make xgo if compilation is done within an xterm)

Notice that the kernel compilation is started from within the freeswan-1.99 directory. The make menugo (or xgo) command will create the necessary symlinks, apply the freeswan patches to the kernel, compile the kernel and the modules. Go for coffee, that can take a while. Also you will have to save and exit the kernel configuration menu that will popup in the process. This is the safest procedure to install freeswan. The problem is that it will install ipsec on your development machine so you will have to remove some files in the /etc directory if you do not want ipsec to start when you next log on:

cd /etc
rm -f init.d/ipsec
rm -f rc?.d/???ipsec

You now have to install the modules and to compress the kernel image:

mkdir /tmp/Bering_modules_2.4.18
cd /usr/src/linux
make modules_install INSTALL_MOD_PATH=/tmp/Bering_modules_2.4.18
upx --best -o linux.upx arch/i386/boot/bzImage

Well you are now done! Your modules are available in the /lib/modules/2.4.18 directory and your floppy linux is the linux.upx you have just generated.
