I am trying to install natt and Klips under Debian Linux 4.0. I follow
exactly README file of openswan and the book of Paul. I faced a
problem that KLIP does not load. What I did is shown below.
I patched the kernel with natt using the following number of commands:
/usr/src/openswan#make nattpatch > /usr/src/openswan-ipsec.natt.patch
cd /usr/src/linux
cat ../openswan-ipsec.natt.patch | patch -p1 -s
The patch works OK and I can build and the kernel. And everything
seems fine till this point.
When I compile openswan by the following command:
/usr/src/openswan#make programs module
the output from the above is long and ends with the following:

=======================start of output====================

KLIPS26 module built successfully.
ipsec.ko is in /usr/src/openswan-2.4.12/modobj26/ipsec.ko

-rw-r--r-- 1 root root 369348 2008-06-09 23:15 ipsec.ko

 269243   10408    5484  285135   459cf ipsec.ko

use make minstall as root to install it

=========================end of  output===========
And it seems fine until this point.
Then, I use these commands to install openswan.
/usr/src/openswan# make install minstall
the output from the above command is very long and the last portion of
the output is shown as follows:

when I veify what I did so far with the following commands I see the
following results:

/usr/src/openswan# ipsec --version

See `ipsec --copyright' for copyright information.

/usr/src/openswan# modprobr ipsec

Can anybody direct me how to install klips, and what exactly I did wrong.
Your help would be very much appreciated.
Thanks and regards.
