Libradsec is a RADIUS library for clients doing RADIUS over UDP or TLS. The goal is to add support for writing servers (and thus proxies) and to add transports TCP and DTLS. The canonical pickup point is http://git.nordu.net/?p=radsecproxy.git;a=shortlog;h=refs/heads/libradsec The source code is licensed under a 3-clause BSD license. See the LICENSE file. Libradsec depends on - libconfuse - libevent2 - openssl (if configured with --enable-tls) To compile the library and the examples, do something like sh autogen.sh && ./configure && make There are a couple of options that can be used when configuring. See ./configure --help for the full list. Worth mentioning here is --enable-tls and --enable-tls-psk. If the preprocessor has a hard time finding some of the header files are, try setting environment variable CPPFLAGS at configure time. Example: CPPFLAGS="-I/usr/local/include" ./configure --enable-tls If the link editor has trouble finding any of the libraries needed, try setting environment variable LDFLAGS at configure time. Example: LDFLAGS="-L/usr/local/lib" ./configure --enable-tls The parts of the library which has been tested has been so on Linux (Debian) with libconfuse (2.7), libevent (2.0.19) and OpenSSL (1.0.1c). The file HACKING contains more detailed info on the state of the various parts of the library.
