You must modify the Makefile under the FreeS/WAN source directory and subdirectories named utils, klips/utils, Pluto,
and lib to specify installation paths. We must modify these files to be compliant with Red Hat's file system structure and install FreeS/WAN files under our PATH environment variable.
Move to the top-level directory of the new FreeS/WAN distribution and type the following commands on your terminal:
Edit the Makefile file, viMakefile and change the following lines:
PUBDIR=/usr/local/sbin
To read:
PUBDIR=/usr/sbin
PRIVDIR=/usr/local/lib/ipsec
To read:
PRIVDIR=/usr/lib/ipsec
FINALPRIVDIR=/usr/local/lib/ipsec
To read:
FINALPRIVDIR=/usr/lib/ipsec
MANTREE=/usr/local/man
To read:
MANTREE=/usr/man
Edit the Makefile file of the subdirectory utils, viutils/Makefile and change the following lines:
PUBDIR=/usr/local/sbin
To read:
PUBDIR=/usr/sbin
PRIVDIR=/usr/local/lib/ipsec
To read:
PRIVDIR=/usr/lib/ipsec
FINALPRIVDIR=/usr/local/lib/ipsec
To read:
FINALPRIVDIR=/usr/lib/ipsec
MANTREE=/usr/local/man
To read:
MANTREE=/usr/man
Edit the Makefile file of the subdirectory klips/utils, viklips/utils/Makefile and change the following lines:
BINDIR=/usr/local/lib/ipsec
To read:
BINDIR=/usr/lib/ipsec
MANTREE=/usr/local/man
To read:
MANTREE=/usr/man
Edit the Makefile file of the subdirectory pluto, vipluto/Makefile and change the following lines:
BINDIR=/usr/local/lib/ipsec
To read:
BINDIR=/usr/lib/ipsec
MANTREE=/usr/local/man
To read:
MANTREE=/usr/man
Edit the Makefile file of the subdirectory lib, vilib/Makefile and change the following lines:
MANTREE=/usr/local/man
To read:
MANTREE=/usr/man
Edit the Makefile file of the subdirectory libdes, vilibdes/Makefile and change the following lines:
LIBDIR=/usr/local/lib
To read:
LIBDIR=/usr/lib
BINDIR=/usr/local/bin
To read:
BINDIR=/usr/bin
INCDIR=/usr/local/include
To read:
INCDIR=/usr/include
MANDIR=/usr/local/man
To read:
MANDIR=/usr/man
The above changes, from step1 to step 6, will locate all files related to the FreeS/WAN software to the destination target directories we have chosen in order to be compliant with the Red Hat file system structure.
Now, we must compile and install FreeSWAN on the server:
[root@deep ]/freeswan-1.3# make insert
[root@deep ]/freeswan-1.3# make programs
[root@deep ]/freeswan-1.3# make install
The make insert command creates a symbolic link /usr/src/linux/net/ipsec, pointing to the KLIPS source directory. It patches some kernel files, where
necessary, to know about KLIPS and/or to fix bugs. It also adds its default configuration to the kernel configuration file, and finally, it makes the KLIPS communication file, /dev/ipsec,
if it's not already there.
The make programs command builds the libraries, Pluto, and various user-level utilities.
The make install will install the Pluto daemon and user-level utilities, and set things up for boot-time startup.
