-1. Required packages
- -----------------
-
- In order to be able to build strongSwan you'll need the GNU Multiprecision
- Arithmetic Library (GMP) available from http://www.swox.com/gmp/.
-
- The libgmp library and the corresponding header file gmp.h are usually
- included in the form of one or two packages in the major Linux
- distributions (SuSE: gmp; Debian unstable: libgmp3, libgmp3-dev).
-
-
-2. Optional packages
- -----------------
-
-2.1 libcurl
- -------
+ Since version 4.x strongSwan uses the GNU build system (Autotools).
+ This simplifies the build process and package maintenance. First, check for
+ the availability of required packages on your system (section 2.). You may
+ want to include support for additional features, which require other
+ packages to be installed (section 3.).
- If you intend to dynamically fetch Certificate Revocation Lists (CRLs)
- from an HTTP server or as an alternative want to use the Online
- Certificate Status Protocol (OCSP) then you will need the libcurl library
- available from http://curl.haxx.se/.
+ To compile an extracted tarball, run the ./configure script first:
- In order to keep the library as compact as possible for use with strongSwan
- you can build libcurl from the sources with the optimized options
+ ./configure
- ./configure --prefix=<dir> --without-ssl \
- --disable-ldap --disable-telnet \
- --disable-dict --disable-gopher \
- --disable-debug \
- --enable-nonblocking --enable-thread
+ You may want to specify some arguments listed in section 3., or see the
+ available options of the script using "./configure --help".
- As an alternative you can use the ready-made packages included with your
- favorite Linux distribution (SuSE: curl, curl-devel).
+ After a successful run of the script, run
- In order to activate the use of the libcurl library in strongSwan you must
- set the USE_LIBCURL option in "Makefile.inc":
+ make
- # include libcurl support (CRL fetching, OCSP and SCEP)
- USE_LIBCURL?=true
+ followed by
- Under Gentoo emerge strongSwan with
+ make install
- USE="curl -ssl" emerge strongswan
+ in the usual manner.
+ To check if your kernel fulfills the requirements, see section 4.
-2.2 OpenLDAP
- --------
+ Next add your connections to "/etc/ipsec.conf" and your secrets to
+ "/etc/ipsec.secrets".
- If you intend to dynamically fetch Certificate Revocation Lists (CRLs)
- from an LDAP server then you will need the libldap library available
- from http://www.openldap.org/.
+ At last start strongSwan with
- OpenLDAP is usually included with your Linux distribution. You will need
- both the run-time and development environments (SuSE: openldap2,
- openldap2-devel).
+ ipsec start
- In order to activate the use of the libldap library in strongSwan you must
- set the USE_LDAP option in "Makefile.inc":
- # include LDAP support (CRL fetching)
- USE_LDAP?=true
+2. Required packages
+ -----------------
- Depending upon whether your LDAP server understands the V3 (preferred) or
- V2 LDAP protocol, uncomment one ot the two following lines:
+ In order to be able to build strongSwan you'll need one of the following
+ cryptographic libraries:
- # Uncomment to enable dynamic CRL fetching using LDAP V3
- LDAP_VERSION=3
- # Uncomment to enable dynamic CRL fetching using LDAP V2
- #LDAP_VERSION=2
+ * The GNU Multiprecision Arithmetic Library (GMP, libgmp)
+ http://www.gmplib.org
+ * The OpenSSL cryptographic library (libcrypto)
+ http://www.openssl.org
+ * The GNU cryptographic library (libgcrypt)
+ http://www.gnupg.org
- The latest OpenLDAP releases use the LDAP V3 protocol, whereas older
- versions require LDAP V2.
+ If no other options are specified during ./configure libgmp will be used.
- Under Gentoo emerge strongSwan with
+ The libraries and the corresponding header files are usually included in
+ the form of one or two packages in the major Linux distributions (for GMP on
+ Debian: libgmp3 and libgmp3-dev).
- USE="ldap -ssl" emerge strongswan
+3. Optional packages
+ -----------------
-2.3 PKCS#11 smartcard library modules
- ---------------------------------
+3.1 HTTP Fetcher
+ ------------
- If you want to securely store your X.509 certificates and private RSA keys
- on a smart card or a USB crypto token then you will need a PKCS #11 library
- for the smart card of your choice. The OpenSC PKCS#11 library (use
- versions >= 0.9.4) available from http://www.opensc.org/ supports quite a
- selection of cards and tokens (e.g. Aladdin eToken Pro32k, Schlumberger
- Cryptoflex e-gate, Oberthur AuthentIC, etc.) but requires that a PKCS#15
- directory structure be present on the smart card. But in principle
- any other PKCS#11 library could be used since the PKCS#11 API hides the
- internal data representation on the card.
+ If you intend to dynamically fetch Certificate Revocation Lists (CRLs)
+ from an HTTP server or as an alternative want to use the Online
+ Certificate Status Protocol (OCSP) then you will need the either of the
+ following libraries:
- For USB crypto token support you must add the OpenCT driver library
- (version >= 0.6.2) from the OpenSC site, whereas for serial smartcard
- readers you'll need the pcsc-lite library and the matching driver from the
- M.U.S.C.L.E project http://www.linuxnet.com/ .
+ * The cURL library (libcurl)
+ http://curl.haxx.se/libcurl/
+ * The LibSoup library (libsoup)
+ https://live.gnome.org/LibSoup
- In order to activate the PKCS#11-based smartcard support in strongSwan
- you must set the USE_SMARTCARD option in "Makefile.inc":
+ In order to activate the use of either of these libraries in strongSwan you
+ must enable the appropriate ./configure switch.
- #include PKCS11-based smartcard support
- USE_SMARTCARD?=true
- During compilation no externel smart card libraries must be present.
- strongSwan directly references a copy of the standard RSAREF pkcs11.h
- header files stored in the pluto/rsaref sub directory. During compile
- time a pathname to a default PKCS#11 dynamical library can be specified
- in "Makefile.inc"
+3.2 LDAP
+ ----
- # Uncomment this line if using OpenSC <= 0.9.6
- # PKCS11_DEFAULT_LIB=\"/usr/lib/pkcs11/opensc-pkcs11.so\"
- # Uncomment tis line if using OpenSC >= 0.10.0
- PKCS11_DEFAULT_LIB=\"usr/lib/opensc-pkcs11.so\"
+ If you intend to dynamically fetch Certificate Revocation Lists (CRLs)
+ from an LDAP server then you will need the libldap library available
+ from http://www.openldap.org/.
- This default path to the easily-obtainable OpenSC library module can be
- simply overridden during run-time by specifying an alternative path in
- ipsec.conf pointing to any dynamic PKCS#11 library of your choice.
-
- config setup
- pkcs11module="/usr/lib/xyz-pkcs11.so"
+ OpenLDAP is usually included with your Linux distribution. You will need
+ both the run-time and development environments (SuSE: openldap2,
+ openldap2-devel).
- Under Gentoo emerge strongSwan with
+ In order to activate the use of the libldap library in strongSwan you must
+ enable the ./configure switch:
- USE="smartcard usb -pam -X" emerge strongswan
+ ./configure [...] --enable-ldap
+ LDAP Protocol version 2 is not supported anymore, --enable-ldap uses always
+ version 3 of the LDAP protocol
-3. Building and running strongSwan with a Linux 2.6 kernel
- -------------------------------------------------------
+3.3 Other pluggable modules
+ -----------------------
- * Because the Linux 2.6 kernel comes with a built-in native IPsec stack,
- you won't need to build the strongSwan kernel modules. Please make sure
- that the the following Linux 2.6 IPsec kernel modules are available:
+ There are many other optional plugins that, for instance, provide support
+ for PKCS#11 or SQL databases.
+ For a more detailed description of these refer to our wiki:
- o af_key
- o ah4
- o esp4
- o ipcomp
- o xfrm_user
- o xfrm_tunnel
+ * http://wiki.strongswan.org
- Also the built-in kernel Cryptoapi modules with selected encryption and
- hash algorithms should be available.
- * First select any desired compile options in "Makefile.inc" (see section 2.
- Optional packages). Then in the strongwan-4.x.x top directory type
+4. Kernel configuration
+ --------------------
- make
+ Since version 4.x strongSwan only supports 2.6.x and 3.x kernels and its
+ native NETKEY IPsec stack. Please make sure that the following IPsec kernel
+ modules are available:
- followed by
+ * af_key
+ * ah4
+ * esp4
+ * ipcomp
+ * xfrm_user
+ * xfrm4_tunnel
- make install
+ These may be built into the kernel or as modules. Modules get loaded
+ automatically at strongSwan startup.
- * Next add your connections to "/etc/ipsec.conf" and your secrets to
- "/etc/ipsec.secrets". Connections that are to be negotiated by the new
- IKEv2 charon keying daemon should be designated by "keyexchange=ikev2" and
- those by the IKEv1 pluto keying daemon either by "keyexchange=ikev1" or
- the default "keyexchange=ike".
+ Also the built-in kernel Cryptoapi modules with selected encryption and
+ hash algorithms should be available.
- * At last start strongSwan with
+ Support for multiple routing tables is also recommended.
- ipsec start
+ For a more up-to-date list of recommended modules refer to:
