Hello. First and foremost I am brand new to linux.
Onto my issue. I am attempting to install the latest
ipsec tools onto a fresh fedora machine using their
latest iso.
I am following THESE basic instructions on how to do it, but I am getting an error when trying to run
Code:
./configure --prefix=/usr --sysconfdir=/etc/racoon --enable-hybrid --enable-frag --enable-dpd --enable-natt
This is the error :
Code:
configure: error: Unable to find linux-2.6 kernel headers. Aborting.
This is the entire output to the command :

The first command on the website checking for ipsec tools came up with nothing. I downloaded the ipsec tools to the downloads folder. I unpacked the file using the given tar command. Not sure what is wrong or how to fix it. I tried searching google but didn't come up with much i could understand.
Any help is appreciated.
