-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
-2006, 2007, 2008, 2009 Free Software Foundation, Inc.
-
-   This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  6. Often, you can also type `make uninstall' to remove the installed
-     files again.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug.  Until the bug is fixed you can use this workaround:
-
-     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *Note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-This is unreleased radsecproxy 2.0-alpha.
+This is not radsecproxy, it's libradsec (see lib/) sharing the
+radsecproxy repository.
 
-radsecproxy is a generic RADIUS proxy that supports both UDP and TLS
-(RadSec) RADIUS transports.  There is also experimental support for
-TCP and DTLS.
+For radsecproxy, see branch 'master'.
 
-It should build on most Linux and BSD platforms by simply typing
-"./configure && make".  It is possible to specify which RADIUS
-transport the build should support.  Without any special options to
-configure, all transports supported by the system will be enabled.
-See the output from "configure --help" for how to change this.
-
-Known build issues:
-- Older BSD's (like NetBSD 4.x) need newer OpenSSL in order to support
-  DTLS.  Workaround: ./configure --disable-dtls.
-- FreeBSD 6.x needs newer OpenSSL to build at all.
-
-To use radsecproxy you need to create a config file which normally is
-called "/etc/radsecproxy.conf".  You can also specify the location
-with the "-c" command line option (see below).  For further
-instructions, please see the enclosed example file and the
-documentation at
-http://software.uninett.no/radsecproxy/?page=documentation
-
-There are five options that may be specified on the command line:
-"-c configfile" to specify a non-default config file path.
-"-d loglevel" to set a loglevel of 1, 2, 3, 4 and 5 where 5 is the
-              most detailed.
-"-f" to run the proxy in the foreground with logging to stderr.
-     Without "-f" the default is to detach as a daemon and log to
-     syslog.
-"-v" just prints version information and exits.
-"-p" (pretend) makes the proxy go through the configuration files as
-     normal, but stops before creating any sockets or doing any
-     serious work.  This is useful for validating config files.
+The repository ca be found at http://git.nordu.net/?p=radsecproxy.git;a=summary .

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a

-\`configure' configures radsecproxy 1.4 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR        program executables [EPREFIX/libexec]

-  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
-  --libdir=DIR            object code libraries [EPREFIX/lib]
-  --includedir=DIR        C header files [PREFIX/include]
-  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
-  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]

-  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
-  --with-ssl              Use SSL (in specified installation directory)
-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  DOCBOOK2X_MAN
-              docbook2x-man
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to <radsecproxy@uninett.no>.

-radsecproxy documentation for developers
-
-1. Overall design
-
-At startup client and server configurations are read. Two lists
-are created, called clconfs and srvconfs. Both contain clsrvconf
-structs.
-
-For each server config, a client writer thread is created. This
-takes care of sending requests to a server.
-
-Next for each known transport type which has a configured client,
-we create listeners. Typically there is a default server port
-that will be listened on, but multiple ports might be configured.
-For each port there will normally be 1-2 sockets (IPv4 and/or IPv6).
-For each socket a thread is created with the listener() defined for
-the transport.
-
-This is all that happens in the main thread. The threads created
-above need to take care of the rest.
-
-Client writers are generally responsible for sending messages to
-clients, and if necessary creating and maintaining connections to
-the client. Client writers create threads for handling replies from
-servers. If connections are used, one thread is created for reading
-from each connection. clientwr() will use connecter() and
-clientconnreader() definitions for the transport.
-
-The listeners may receive RADIUS messages directly, which is the
-case for UDP which is not connection based. Or they may receive
-connections and create a new thread for handling each incoming
-connection, where that thread will receive RADIUS messages.
-The function receiving RADIUS client requests is generally called
-xxxserverrd, where xxx is the transport name. The server reader
-is responsible for creating a server writer thread that takes care
-of sending RADIUS replies to a client.
-
-2. RADIUS message processing
-
-In 1 we described the threads used and the high level operations.
-We will now describe how RADIUS messages are processed and flow
-through the system.
-
-An incoming RADIUS request from a client is handled by a server
-reader. The server reader calls newrequest() to obtain a request
-struct. It sets rq->buf to point to the received message, rq->from
-to point to the client struct for the client, and might for some
-transports specify additional data. E.g. for UDP, the source port
-and socket it was received on. The reader must make sure buf is
-at least as large as the specified RADIUS message length. The
-client reader calls radsrv(rq). When that returns it just waits
-for the next message.
-
-radsrv() is in a way the core part of the proxy. It takes care
-of validation, processing and routing of incoming requests.
-It first creates a radmsg struct calling buf2radmsg(). This also
-takes care of basic validation (e.g. that lengths add up) and
-checking message authenticators. Unless it receives a valid
-Access Request, Accounting Request or Status Server, it will
-drop the request and return.
-
-It next calls addclientrq() which adds this request to a request
-queue for rq->from. Before adding it to the queue, it checks if
-it is a duplicate of something already in the queue. If a
-duplicate, radsrv() drops the request and returns.
-
-Next radsrv() checks if it received a Status Server message. In
-that case it responds with Access Accept and returns.
-
-Next it applies any rewritein rules and also checks TTL attribute.
-If TTL expired, it will drop request and return.
-
-Next it looks for a User-Name attribute. If not present it will
-will drop the request. However, if it is an accounting request
-it will first send an accounting response.
-
-Next it calls findserver() to pick a server for sending the
-message to. For this it will use the user-name attribute and the
-realm definitions. It also takes into account which servers are
-alive.
-
-If no server is found it will drop the message. However, in
-certain cases it may send a reject or accounting response message.
-
-Next it reencrypts any attributes that are encrypted based on
-the secrets of clients/servers. And after that, decrements TTL if
-present, and applies any rewriteout rules.
-
-Finally radsrv() calls sendrq(rq) to pass the request to the
-chosen server.
-
-sendrq() checks the request queue for a server. The request queue
-is an array holding 256 entries, one for each possible message ID.
-Normally it will start looking for a free slot at the ID after the
-last entry inserted in the queue (0 follows 255). However in a
-special case where sendrq() is called to send a status-server message,
-it will always use ID 0. If status-server is enabled, ID 0 is not used
-for other requests. If there are no free slots, the message is
-discarded.
-
-When finding a free slot, it does, "to->requests[i].rq = rq" and
-signals the writer thread : "pthread_cond_signal(&to->newrq_cond)".
-After that, it returns, and the server reader thread can wait for a
-new client request.
-
-We will now consider the client writer thread that takes care of
-sending this request to a server.
-
-clientwr() continually looks for requests in its request buffer
-and tries to send them to a server. It uses timers so that it can
-sleep waiting for a new request, or sending status server, or
-re-sending an existing request. When a new request comes in, it
-will send it ASAP to the server and set tries to 1. For the
-server there is a retryinterval timer. retryinterval seconds later
-clientwr() will resend or remove the request. It is removed if the
-server's retrycount parameter is exceeded (0 retries if reliable
-transport). Status server messages are never resent.
-
-The handling of the request stops here, unless we get a reply.
-We will now describe how replies are handled.
-
-Each transport has a function called something xxxclientrd() for
-receiving replies from a server. This is run as a separate thread.
-All they do is read a RADIUS message and call replyh(server, buf)
-where server points to the server struct for the server, and buf
-is a buffer large enough to contain the entire RADIUS message. It
-will not read another message until replyh() returns.
-
-We will now consider replyh(). It will first check if there is an
-outstanding request matching the id of the reply. This is done by
-checking the request queue of the server.
-
-If it maches a request, it will validate and authenticate the
-reply by calling buf2radmsg(). If this fails or the message type
-is not one of Access Accept, Access Reject, Access Challenge or
-Accounting Response, the reply is ignored.
-
-If the request was a status-server message, it simply removes
-the request and returns.
-
-Next it will apply any rewritein rules and check TTL attribute if
-present. If TTL is exceeded, the reply is ignored.
-
-Next it reencrypts some attributes with the secret of the client
-the original request came from, and which the reply will be sent
-back to. It also applies any rewriteout rules.
-
-Finally to pass the reply back to the client, it does
-"rqout->rq->msg = msg" to store the reply message in the request,
-and calls sendreply() with rqout->rq as parameter. When
-sendreply() returns, we free the request from the server's
-request queue. This also means that the ID can be used for a new
-request.
-
-Now about sendreply(). All it does is basically to assemble the
-reply message, take care of authenticators and set rq->replybuf
-to point to the result. After that it adds a pointer to rq to
-the clients reply queue and signals the server writer who is
-responsible for sending replies to the client.
-
-The server writer is a separate thread created by the server reader,
-typically called something like xxxserverwr. All it does is to send
-whatever it finds in its replyq to the client and remove it. When
-the queue is empty it waits for a signal from a sendreply().
-
-The above shows the complete flow. It might be worth also looking a
-bit more at the state created for each request though.
-
-As mentioned above, each request received from a client is stored in
-request queue for the client. The request is stored in a request
-struct which looks like this:
-
-struct request {
-    uint8_t *buf, *replybuf;
-    struct radmsg *msg;
-    ...
-};
-
-This request will remain in the queue until a new request is
-received with the same id and which is not a duplicate. The
-new one then replaces the previous.
-
-Initially for a new request, only buf is used (of the above specified
-fields). Next the message is parsed and validated, and if ok, it is
-stored in msg. buf with the request is freed.
-
-In sendrq() a request that is to be sent to a server, is again
-reassembled from rq->msg into rq->buf.
-
-When a reply is received, it will again be parsed and validated, and
-if ok, it will free the old rq->msg, and store the new instead.
-
-Finally, in sendreply() rq->replybuf is created from rq->msg, and
-rq->msg is freed. rq->replybuf is kept so that if a duplicate request
-is received later, we can just return rq->replybuf.
-
-rq->buf is removed by freerqoutdata(), because then we will not try
-to send the request in rq->buf any more.
-
-Request structs should perhaps be freed when they "expire", rather
-than wait until a new request with the same ID comes along.
-
-x. Transports
-
-struct protodefs protodefs[] contains definitions of the different
-transport protocols. We will here describe the different parameters.
-
-struct protodefs {
-    char *name;
-This should be a textual name for the transport, e.g. "udp". This is
-used in client/server configurations and for debug/log messages.
-    
-    char *secretdefault;
-Some transports like TLS that provides strong encryption, may have a
-default RADIUS secret, since the RADIUS encryption is not needed.
-    
-    uint8_t socktype;
-Typically set to SOCK_DGRAM or SOCK_STREAM. This is used when a
-socket for the transport is created.
-    
-    char *portdefault;
-The default server port for the transport, e.g. 1812.
-    
-    uint8_t retrycountdefault;
-How many time a client request should be resent. For a reliable
-transport like TCP/TLS, this should be 0.
-    
-    uint8_t retrycountmax;
-The maximum allowed configurable value for retrycount. For reliable
-transport it should probably be 0.
-    
-    uint8_t retryintervaldefault;
-This is the default for how many seconds there should be between each
-retry. For a reliable transport with 0 retries, this controls how
-long it should wait for a reply to the client request.
-    
-    uint8_t retryintervalmax;
-This is the maximum allowed retryinterval
-    
-    uint8_t duplicateintervaldefault;
-This is the time period two requests with the same UDP source port
-and request authenticator are considered duplicates. If a reply has
-been sent to the first request, then that is resent. If no reply
-has been sent, the second request is ignored.
-    
-    void *(*listener)(void*);
-Each transport must define a listener function for the sockets
-created by the transport. The socket is created by radsecproxy
-core. If successful, the listener is called.
-    
-    int (*connecter)(struct server *, struct timeval *, int, char *);
-When creating a new server, a clientwr() thread is created for sending
-requests to the server. If a connecter() is defined for the transport,
-clientwr() will call connecter() and exit if connecter() returns 0.
-
-    void *(*clientconnreader)(void*);
-If a connecter() is defined, then when that successfully returns,
-a separate thread is created for reading from the connection. This
-thread is responsible for handling replies from a server.
-
-    int (*clientradput)(struct server *, unsigned char *);
-Used by clientwr() for sending a RADIUS message.
-
-    void (*addclient)(struct client *);
-Need only be defined if need to override default client creation.
-Used by UDP to have a common reply queue, rather than one per client.
-
-    void (*addserverextra)(struct clsrvconf *);
-Need only be defined if something needs to be done in addition to
-the default server creation.
-    
-    uint8_t freesrcprotores;
-Whether should free the resolver state for source ports and
-addresses after initial startup.
-
-    void (*initextra)();
-Can be defined it extra initialisation is needed for the transport.

-Documentation for gconfig
-
-gconfig is a configuration file parser. It is generic in the sense that it can
-be used for different applications that need different configuration keywords
-and value. There is however a fixed syntax.
-
-The basic syntax is
-
-option-name value
-or
-option-name = value
-
-where white space is used as delimiters, where you can have any amount of
-whitespace (spaces and tabs) where there is a space above. option-name cannot
-contain spaces. A value can contain spaces if the value is quoted. E.g.
-
-option-name = "option value"
-
-There is a special keyword "include" used for including config files.
-Anywhere in a config file one can write "include filespec". At that
-point the entire content of a file pointed to by filespec will be
-inserted. When the end of the file is read, the config parser will
-continue with whatever is after include. "filespec" can use UNIX
-shell type globbing, so you may do e.g. "include /etc/gconf.d/*" to
-include everything in that directory. This will behave exactly like
-including each of the files separately (in alphabetic order).
-
-In addition to this, one may also group options together into
-blocks, where blocks also have names.
-
-A block has the syntax
-
-type name {
-     option-name value
-     option-name value
-     ...
-}
-
-The application specifies which block types are valid, and which
-option-names and syntaxes can be used for each of the types.
-
-The available option syntaxes (or types) are String, Integer and
-Boolean.
-
-Usually the same option-name cannot be repeated (unless in different
-blocks). For Strings one can specify whether it is allowed or not.
-Also, for strings one can use hex notation for bytes. This works
-similar to URL hex escaping. E.g. a space can be written as "%20".
-
-radsecproxy uses gconfig and shows what is possible. Here is an
-example extracted from getmainconfig() from radsecproxy.
-
-struct gconffile *cfs;
-cfs = openconfigfile(configfile);
-    if (!getgenericconfig(&cfs, NULL,
-                          "ListenUDP", CONF_MSTR, &listenudp,
-                          "LogDestination", CONF_STR, &logdestination,
-                          "LogLevel", CONF_LINT, &loglevel,
-                          "LoopPrevention", CONF_BLN, &loopprevention,
-                          "Client", CONF_CBK, confclient_cb, NULL,
-                          NULL
-                          ))
-        debugx(1, DBG_ERR, "configuration error"); /* exit */
-    /* parsing successful, continue normal operations */
-
-The arguments to getgenericconfig are as follows. First there is a
-gconffile struct, this is normally a single file, but as we discuss later,
-it can also be a list of files (or data). The second parameter should be
-NULL when not in a block, or the block name if inside one. This is only
-used for logging.
-
-After this one lists all the legal option and block names that are allowed.
-For each option one specifies a name followed by a syntax type and a pointer to
-the variable that will hold the value. The syntax types are CONF_STR for a
-string, CONF_MSTR for string when the option can be used multiple times,
-CONF_LINT for Integer (long int), CONF_BLN for Boolean ("on" or "off"). For
-blocks one uses CONF_CBK followed by a callback function for handling the
-block, and a pointer to userdata that can be passed to the callback. Normally
-this would just be set to NULL.
-
-We will now discuss each of the syntax types and blocks in more detail.
-
-CONF_STR:
-This is used for strings. The value argument must be of type "char **". If
-the option is found in the config, it will allocate memory for a null-terminated
-copy of the string and return a pointer to this. The value argument is not
-modified if the option is not used. In the example above, one might do
-"char *logdestination = NULL". One then uses &logdestination for the
-argument, and can check for NULL to see whether the option was present.
-
-CONF_MSTR:
-This is used for strings when the option can be used multiple times. It
-will return an array of strings in the order they are found in the config.
-The value argument must be of type "char ***". One might do
-"char **listenudp = NULL", and use &listenudp for the argument. Memory will
-be allocated for the array and the strings if the option is used. If no
-options are found, the value is unchanged. If there is at least one value,
-one will get an array of strings, and the last element of the array will be
-set to NULL.
-
-CONF_LINT:
-The option value argument must be of type "long int *". If the option is
-present, the value will be set, else it will not be modified.
-
-CONF_BLN:
-The option value argument must be of type "uint8_t *". It is set to 0 or 1
-for "off" or "on" resp. It is only modified if the option is found.
-
-CONF_CBK:
-This is a block where one uses a call back. Here is an example callback:
-
-int confclient_cb(struct gconffile **cf, void *arg, char *block, char *opt, char
- *val) {
-    char *type = NULL, *host = NULL;
-    debug(DBG_DBG, "confclient_cb called for %s", block);
-    if (!getgenericconfig(cf, block,
-                          "type", CONF_STR, &type,
-                          "host", CONF_STR, &host,
-			  NULL
-			  ))
-        debugx(1, DBG_ERR, "configuration error"); /* exit */
-    /* parsing successful, continue normal operations */
-
-Here cf is the list of config files we're using, arg is a pointer to
-userdata (the parameter after the name of the callback function, often
-this is just set to NULL). opt is the type of block, in this case it will
-be set to "client". val is the value of the block. E.g. if the config said
-
-client example {
-	type udp
-	host 1.2.3.4
-}
-
-then val will be set to "example". The string block is set to
-"client example" (opt val) and is normally just used for logging.
-Note that the opt, val and optval parameters to the callback will all be
-freed when the callback function exits.
-
-The gconffile struct can hold a list of config files. Typically one would
-just use cfs = openconfigfile(configfile) as above. But one can use any of
-the ones below. It can be used to create a new struct (a pointer to NULL),
-or a pointer to an existing struct where new files are pushed (as a stack).
-The latest pushed is used first, when that is used it continues reading
-from the next.
-
-int pushgconfdata(struct gconffile **cf, const char *data);
-This can be used to read config stored in memory
-
-FILE *pushgconfpath(struct gconffile **cf, const char *path);
-Here one specifies a file path (no globbing)
-
-FILE *pushgconfpaths(struct gconffile **cf, const char *path);
-Here one specifies a filespec with globbing. In case of multiple files,
-they are pushed in reverse alphabetical order so that the alphabetically
-first file is read first.
-
-FILE *pushgconffile(struct gconffile **cf, FILE *file, const char *description);
-This can be used for reading config from an already open file descriptor.
-
-For a complete example, see radsecproxy.

-.TH radsecproxy 1 "12 March 2009"
-
-.SH "NAME"
-radsecproxy - a generic RADIUS proxy that provides both RADIUS UDP and TCP/TLS (RadSec) transport.
-
-.SH "SYNOPSIS"
-.HP 12
-radsecproxy [-c configfile] [-d debuglevel] [-f] [-i pidfile] [-p] [-v]
-.sp
-
-.SH "DESCRIPTION"
-radsecproxy is a \fBgeneric RADIUS proxy\fR that in addition to to
-usual \fBRADIUS UDP\fR transport, also supports \fBTLS (RadSec)\fR. The
-aim is for the proxy to have sufficient features to be flexible,
-while at the same time to be small, efficient and easy to configure.
-Currently the executable on Linux is only about \fI48 KB\fR, and it uses
-about \fI64 KB\fR (depending on the number of peers) while running.
-.sp
-The proxy was initially made to be able to deploy \fBRadSec\fR (RADIUS
-over TLS) so that all RADIUS communication across network links
-could be done using TLS, without modifying existing RADIUS software.
-This can be done by running this proxy on the same host as an existing
-RADIUS server or client, and configure the existing client/server to
-talk to localhost (the proxy) rather than other clients and servers
-directly.
-.sp
-There are however other situations where a RADIUS proxy might be
-useful. Some people deploy RADIUS topologies where they want to
-route RADIUS messages to the right server. The nodes that do purely
-routing could be using a proxy. Some people may also wish to deploy
-a proxy on a site boundary. Since the proxy \fBsupports both IPv4
-and IPv6\fR, it could also be used to allow communication in cases
-where some RADIUS nodes use only IPv4 and some only IPv6.
-
-.SH "OPTIONS"
-.TP
-.B -f
-.sp
-\fIRun in foreground\fR
-.sp
-By specifying this option, the proxy will run in foreground mode. That
-is, it won't detach. Also all logging will be done to stderr.
-
-.TP
-.B -d <debug level>
-.sp
-\fIDebug level\fR
-.sp
-This specifies the debug level. It must be set to 1, 2, 3, 4 or 5, where
-1 logs only serious errors, and 5 logs everything. The default is 2 which
-logs errors, warnings and a few informational messages.
-
-.TP
-.B -p
-.sp
-\fIPretend\fR
-.sp
-The proxy reads configuration files and performs initialisation as
-usual, but exits prior to creating any sockets. It will return different
-exit codes depending on whether the configuration files are okay. This
-may be used to verify configuration files, and can be done while another
-instance is running.
-
-.TP
-.B -v
-.sp
-\fIPrint version\fR
-.sp
-When this option is specified, the proxy will simply print version
-information and exit.
-
-.TP
-.B -c <config file path>
-.sp
-\fIConfig file path\fR
-.sp
-This option allows you to specify which config file to use. This is useful
-if you want to use a config file that is not in any of the default locations.
-
-.TP
-.B -i <pid file path>
-.sp
-\fIPID file path\fR
-.sp
-This option tells the proxy to create a PID file with the specified path.
-
-.SH "SIGNALS"
-The proxy generally exits on all signals. The exceptions are listed below.
-
-.TP
-.B SIGHUP
-.sp
-When logging to a file, this signal forces a reopen of the log file.
-
-.TP
-.B SIGPIPE
-.sp
-This signal is ignored.
-
-.SH "FILES"
-.TP
-.B /etc/radsecproxy.conf
-.sp
-The default configuration file.

- *              rd is responsible for init and launching wr
- * For TLS there is a server instance that launches tlsserverrd for each TLS peer
- *          each tlsserverrd launches tlsserverwr
- * For each UDP/TLS peer there is clientrd and clientwr, clientwr is responsible
- *          for init and launching rd
- *
- * serverrd will receive a request, processes it and puts it in the requestq of

- * serverwr monitors its reply and sends replies
- *
- * In addition to the main thread, we have:
- * If UDP peers are configured, there will be 2 + 2 * #peers UDP threads
- * If TLS peers are configured, there will initially be 2 * #peers TLS threads
- * For each TLS peer connecting to us there will be 2 more TLS threads
- *       This is only for connected peers
- * Example: With 3 UDP peers and 30 TLS peers, there will be a max of
- *          1 + (2 + 2 * 3) + (2 * 30) + (2 * 30) = 129 threads

-/* Bugs:
- * May segfault when dtls connections go down? More testing needed
- * Remove expired stuff from clients request list?
- * Multiple outgoing connections if not enough IDs? (multiple servers per conf?)
- * Useful for TCP accounting? Now we require separate server config for alt port

-# will be checked.
-#
-# The simplest configuration you can do is:

-# If you want one cert for all clients and another for all servers, use

-# particular server to use something else you could specify a block
-# "tls myserver" and then reference that for that server. If you always
-# name the tls block in the client/server config you don't need a default
-
-# Now we configure clients, servers and realms. Note that these and
-# also the lines above may be in any order, except that a realm
-# can only be configured to use a server that is previously configured.

-# A realm can be a literal domain name, * which matches all, or a

-    <title>Description</title>
-    <para>
-When the proxy server starts, it will first check the command line arguments,
-and then read the configuration file. Normally radsecproxy will read the
-configuration file <filename>/etc/radsecproxy.conf</filename>. The command
-line <option>-c</option> option can be used to instead read an alternate
-file (see
-      <citerefentry>
-        <refentrytitle>radsecproxy</refentrytitle>
-        <manvolnum>1</manvolnum>
-      </citerefentry>
-for details).
-    </para>
-    <para>
-    If the configuration file can not be found, the proxy will exit with an
-    error message. Note that there is also an include facility so that any
-    configuration file may include other configuration files. The proxy will
-    also exit on configuration errors.
-    </para>
-  </refsect1>
-  <refsect1>
-    <title>Configuration Syntax</title>
-    <para>
-When the configuration file is processed, whitespace (spaces and tabs) are
-generally ignored. For each line, leading and trailing whitespace are ignored.
-A line is ignored if it is empty, only consists of whitespace, or if the first 
-non-whitespace character is a <literal>#</literal>. The configuration is
-generally case insensitive, but in some cases the option values (see below)
-are not.
-    </para>
-    <para>
-There are two types of configuration structures than can be used. The first
-and simplest are lines on the format <emphasis>option value</emphasis>. That
-is, an option name, see below for a list of valid options, followed by
-whitespace (at least one space or tab character), followed by a value. Note
-that if the value contains whitespace, then it must be quoted using
-<literal>""</literal> or <literal>''</literal>. Any whitespace
-in front of the option or after the value will be ignored.
-    </para>
-    <para>
-The other type of structure is a block. A block spans at least two lines, and
-has the format:
-      <blockquote>
-<literallayout>
-blocktype name {
-    option value
-    option value
-    ...
-}
-</literallayout>
-      </blockquote>
-That is, some blocktype, see below for a list of the different block types, and
-then enclosed in braces you have zero or more lines that each have the
-previously described <emphasis>option value</emphasis> format. Different block
-types have different rules for which options can be specified, they are listed
-below. The rules regarding white space, comments and quotes are as above. Hence
-you may do things like:
-      <blockquote>
-        <para>
-<literallayout>
-blocktype name {
-#    option value
-    option "value with space"
-    ...
-}
-</literallayout>
-        </para>
-      </blockquote>
-    </para>
-    <para>
-Option value characters can also be written in hex. This is done by writing the
-character <literal>%</literal> followed by two hexadecimal digits. If a
-<literal>%</literal> is used without two following hexadecimal digits, the
-<literal>%</literal> and the following characters are used as written. If you
-want to write a <literal>%</literal> and not use this decoding, you may of
-course write <literal>%</literal> in hex; i.e., <literal>%25</literal>.
-    </para>
-    <para>
-There is one special option that can be used both as a basic option and inside
-all blocks. That is the option <literal>include</literal> where the value
-specifies files to be included. The value can be a single file, or it can use
-normal shell globbing to specify multiple files, e.g.:
-      <blockquote>
-        <para>
-include /etc/radsecproxy.conf.d/*.conf
-        </para>
-      </blockquote>
-The files are sorted alphabetically. Included files are read in the order they
-are specified, when reaching the end of a file, the next file is read. When
-reaching the end of the last included file, the proxy returns to read the next
-line following the <literal>include</literal> option. Included files may again
-include other files.
-    </para>
-  </refsect1>
-  <refsect1>
-    <title>Basic Options</title>
-    <para>
-The following basic options may be specified in the configuration file. Note
-that blocktypes and options inside blocks are discussed later. Note that none
-of these options are required, and indeed in many cases they are not needed.
-Note that you should specify each at most once. The behaviour with multiple
-occurences is undefined.

-      <varlistentry>
-        <term><literal>logLevel</literal></term>
-        <listitem>
-	  <para>
-This option specifies the debug level. It must be set to 1, 2, 3, 4 or 5, where
-1 logs only serious errors, and 5 logs everything. The default is 2 which logs
-errors, warnings and a few informational messages. Note that the command line

-This specifies where the log messages should go. By default the messages go to
-syslog with facility <literal>LOG_DAEMON</literal>. Using this option you can
-specify another syslog facility, or you may specify that logging should be to
-a particular file, not using syslog. The value must be either a file or
-syslog URL. The file URL is the standard one, specifying a local file that
-should be used. For syslog, you must use the syntax:
-<literal>x-syslog:///FACILITY</literal> where <literal>FACILITY</literal> must
-be one of <literal>LOG_DAEMON</literal>, <literal>LOG_MAIL</literal>,
-<literal>LOG_USER</literal>, <literal>LOG_LOCAL0</literal>,
-<literal>LOG_LOCAL1</literal>, <literal>LOG_LOCAL2</literal>,
-<literal>LOG_LOCAL3</literal>, <literal>LOG_LOCAL4</literal>,
-<literal>LOG_LOCAL5</literal>, <literal>LOG_LOCAL6</literal> or
-<literal>LOG_LOCAL7</literal>. You may omit the facility from the URL to
-specify logging to the default facility, but this is not very useful since
-this is the default log destination. Note that this option is ignored if
-<option>-f</option> is specified on the command line.

-Normally the proxy will listen to the standard RADIUS UDP port
-<literal>1812</literal> if configured to handle UDP clients. On most systems it
-will do this for all of the system's IP addresses (both IPv4 and IPv6). On some
-systems however, it may respond to only IPv4 or only IPv6. To specify an
-alternate port you may use a value on the form <literal>*:port</literal> where
-port is any valid port number. If you also want to specify a specific address
-you can do e.g. <literal>192.168.1.1:1812</literal> or
-<literal>[2001:db8::1]:1812</literal>. The port may be omitted if you want the
-default one (like in these examples). These examples are equivalent to
-<literal>192.168.1.1</literal> and <literal>2001:db8::1</literal>. Note that

-client, and what parameters should be used for that client. The name of the
-client block must (with one exception, see below) be either the IP address
-(IPv4 or IPv6) of the client, an IP prefix (IPv4 or IPv6) on the form
-IpAddress/PrefixLength, or a domain name (FQDN). Note that literal IPv6
-addresses must be enclosed in brackets.
-    </para>
-    <para>
-If a domain name is specified, then this will be resolved immediately to all
-the addresses associated with the name, and the proxy will not care about any
-possible DNS changes that might occur later. Hence there is no dependency on
-DNS after startup.
-    </para>
-    <para>
-When some client later sends a request to the proxy, the proxy will look at the
-IP address the request comes from, and then go through all the addresses of
-each of the configured clients (in the order they are defined), to determine
-which (if any) of the clients this is.
-    </para>
-    <para>
-In the case of TLS/DTLS, the name of the client must match the FQDN or IP
-address in the client certificate. Note that this is not required when the
-client name is an IP prefix.
-    </para>
-    <para>
-Alternatively one may use the <literal>host</literal> option inside a client
-block. In that case, the value of the <literal>host</literal> option is used as
-above, while the name of the block is only used as a descriptive name for the
-administrator. The host option may be used multiple times, and can be a mix of
-addresses, FQDNs and prefixes.
-    </para>
-    <para>
-The allowed options in a client block are <literal>host</literal>,
-<literal>type</literal>, <literal>secret</literal>, <literal>tls</literal>,
-<literal>certificateNameCheck</literal>,
-<literal>matchCertificateAttribute</literal>,
-<literal>duplicateInterval</literal>, <literal>addTTL</literal>,
-<literal>rewrite</literal>, <literal>rewriteIn</literal>,
-<literal>rewriteOut</literal> and <literal>rewriteAttribute</literal>.
-We already discussed the
-<literal>host</literal> option. The value of <literal>type</literal> must be
-one of <literal>udp</literal>, <literal>tcp</literal>, <literal>tls</literal>
-or <literal>dtls</literal>. The value of <literal>secret</literal> is the
-shared RADIUS key used with this client. If the secret contains whitespace,
-the value must be quoted. This option is optional for TLS/DTLS.
-    </para>
-    <para>
-For a TLS/DTLS client you may also specify the <literal>tls</literal> option.
-The option value must be the name of a previously defined TLS block. If this
-option is not specified, the TLS block with the name
-<literal>defaultClient</literal> will be used if defined. If not defined, it
-will try to use the TLS block named <literal>default</literal>. If the
-specified TLS block name does not exist, or the option is not specified and
-none of the defaults exist, the proxy will exit with an error.
-    </para>
-    <para>
-For a TLS/DTLS client, the option <literal>certificateNameCheck</literal>
-can be set
-to <literal>off</literal>, to disable the default behaviour of matching CN or
-SubjectAltName against the specified hostname or IP address.
-    </para>
-    <para>
-Additional validation of certificate attributes can be done by use of the
-<literal>matchCertificateAttribute</literal> option. Currently one can only do
-some matching of CN and SubjectAltName. For regexp matching on CN, one can use
-the value <literal>CN:/regexp/</literal>. For SubjectAltName one can only do
-regexp matching of the URI, this is specified as
-<literal>SubjectAltName:URI:/regexp/</literal>. Note that currently this option
-can only be specified once in a client block.
-    </para>
-    <para>
-The <literal>duplicateInterval</literal> option can be used to specify for how
-many seconds duplicate checking should be done. If a proxy receives a new
-request within a few seconds of a previous one, it may be treated the same if
-from the same client, with the same authenticator etc. The proxy will then
-ignore the new request (if it is still processing the previous one), or
-returned a copy of the previous reply.
-    </para>
-    <para>
-The <literal>addTTL</literal> option is similar to the
-<literal>addTTL</literal> option used in the basic config. See that for
-details. Any value configured here overrides the basic one when sending
-messages to this client.
-    </para>
-    <para>
-The <literal>rewrite</literal> option is deprecated. Use
-<literal>rewriteIn</literal> instead.
-    </para>
-    <para>
-The <literal>rewriteIn</literal> option can be used to refer to a rewrite block
-that specifies certain rewrite operations that should be performed on incoming
-messages from the client. The rewriting is done before other processing.
-For details, see the rewrite block text below. Similarly to
-<literal>tls</literal> discussed above, if this option is not used, there is a
-fallback to using the <literal>rewrite</literal> block named
-<literal>defaultClient</literal> if it exists; and if not, a fallback to a
-block named <literal>default</literal>.
-    </para>
-    <para>
-The <literal>rewriteOut</literal> option is used in the same way as
-<literal>rewriteIn</literal>, except that it specifies rewrite operations that
-should be performed on outgoing messages to the client. The rewriting is done
-after other processing. Also, there is no rewrite fallback if this option is
-not used.
-    </para>
-    <para>
-The <literal>rewriteAttribute</literal> option currently makes it possible to
-specify that the User-Name attribute in a client request shall be rewritten in
-the request sent by the proxy. The User-Name attribute is written back to the
-original value if a matching response is later sent back to the client. The
-value must be on the form User-Name:/regexpmatch/replacement/. Example usage:
-      <blockquote>
-        <para>
-rewriteAttribute User-Name:/^(.*)@local$/\1@example.com/
-        </para>
-      </blockquote>
-    </para>

-    <title>Server Block</title>
-    <para>
-The server block is used to configure a server. That is, tell the proxy about a
-server, and what parameters should be used when communicating with that server.
-The name of the server block must (with one exception, see below) be either the
-IP address (IPv4 or IPv6) of the server, or a domain name (FQDN). If a domain
-name is specified, then this will be resolved immediately to all the addresses
-associated with the name, and the proxy will not care about any possible DNS
-changes that might occur later. Hence there is no dependency on DNS after
-startup. If the domain name resolves to multiple addresses, then for UDP/DTLS
-the first address is used. For TCP/TLS, the proxy will loop through the
-addresses until it can connect to one of them. In the case of TLS/DTLS, the
-name of the server must match the FQDN or IP address in the server certificate.
-    </para>
-    <para>
-Alternatively one may use the <literal>host</literal> option inside a server
-block. In that case, the value of the <literal>host</literal> option is used as
-above, while the name of the block is only used as a descriptive name for the
-administrator. Note that multiple host options may be used. This will then be
-treated as multiple names/addresses for the same server. When initiating a TCP/TLS
-connection, all addresses of all names may be attempted, but there is no failover
-between the different host values. For failover one must use separate server
-blocks.
-    </para>
-    <para>
-Note that the name of the block, or values of host options may include a
-port number (separated with a column). This port number will then override the
-default port or a port option in the server block. Also note that literal IPv6
-addresses must be enclosed in brackets.
-    </para>
-    <para>
-The allowed options in a server block are <literal>host</literal>,
-<literal>port</literal>, <literal>type</literal>, <literal>secret</literal>,
-<literal>tls</literal>, <literal>certificateNameCheck</literal>,
-<literal>matchCertificateAttribute</literal>, <literal>addTTL</literal>,
-<literal>rewrite</literal>,
-<literal>rewriteIn</literal>, <literal>rewriteOut</literal>,
-<literal>statusServer</literal>, <literal>retryCount</literal>,
-<literal>retryInterval</literal>, <literal>dynamicLookupCommand</literal>
-and <literal>loopPrevention</literal>.
-    </para>
-    <para>
-We already discussed the <literal>host</literal> option. The
-<literal>port</literal> option allows you to specify which port number the
-server uses. The usage of <literal>type</literal>, <literal>secret</literal>,
-<literal>tls</literal>, <literal>certificateNameCheck</literal>,
-<literal>matchCertificateAttribute</literal>, <literal>addTTL</literal>,
-<literal>rewrite</literal>,
-<literal>rewriteIn</literal> and <literal>rewriteOut</literal> are just as
-specified for the <literal>client block</literal> above, except that
-<literal>defaultServer</literal> (and not <literal>defaultClient</literal>)
-is the fallback for the <literal>tls</literal>, <literal>rewrite</literal>
-and <literal>rewriteIn</literal> options.
-    </para>
-    <para>
-<literal>statusServer</literal> can be specified to enable the use of
-status-server messages for this server. The value must be either
-<literal>on</literal> or <literal>off</literal>. The default when not
-specified, is <literal>off</literal>. If statusserver is enabled, the proxy
-will during idle periods send regular status-server messages to the server
-to verify that it is alive. This should only be enabled if the server
-supports it.
-    </para>
-    <para>
-The options <literal>retryCount</literal> and
-<literal>retryInterval</literal> can be used to specify how many times the
-proxy should retry sending a request and how long it should wait between each
-retry. The defaults are 2 retries and an interval of 5s.
-    </para>
-    <para>
-The option <literal>dynamicLookupCommand</literal> can be used to specify a
-command that should be executed to dynamically configure and use a server.
-The use of this feature will be documented separately/later.
-    </para>
-    <para>
-Using the <literal>loopPrevention</literal> option here overrides any
-basic setting of this option.  See section <literal>BASIC
-OPTIONS</literal> for details on this option.
-    </para>
-  </refsect1>
-  <refsect1>
-    <title>Realm Block</title>
-    <para>
-When the proxy receives an Access-Request it needs to figure out to which
-server it should be forwarded. This is done by looking at the Username attribute
-in the request, and matching that against the names of the defined realm blocks.
-The proxy will match against the blocks in the order they are specified, using
-the first match if any. If no realm matches, the proxy will simply ignore the
-request. Each realm block specifies what the server should do when a match is
-found. A realm block may contain none, one or multiple <literal>server</literal>
-options, and similarly <literal>accountingServer</literal> options. There are
-also <literal>replyMessage</literal> and <literal>accountingResponse</literal>
-options. We will discuss these later.
-    </para>
-    <refsect2>
-      <title>Realm block names and matching</title>
-      <para>
-In the general case the proxy will look for a <literal>@</literal> in the
-username attribute, and try to do an exact case insensitive match between what
-comes after the <literal>@</literal> and the name of the realm block. So if you
-get a request with the attribute value <literal>anonymous@example.com</literal>,
-the proxy will go through the realm names in the order they are specified,
-looking for a realm block named <literal>example.com</literal>.
-      </para>
-      <para>
-There are two exceptions to this, one is the realm name <literal>*</literal>
-which means match everything. Hence if you have a realm block named
-<literal>*</literal>, then it will always match. This should then be the last
-realm block defined, since any blocks after this would never be checked. This
-is useful for having a default.
-      </para>
-      <para>
-The other exception is regular expression matching. If the realm name starts
-with a <literal>/</literal>, the name is treated as an regular expression. A
-case insensitive regexp match will then be done using this regexp on the value
-of the entire Username attribute. Optionally you may also have a trailing
-<literal>/</literal> after the regexp. So as an example, if you want to use
-regexp matching the domain <literal>example.com</literal> you could have a
-realm block named <literal>/@example\\.com$</literal>. Optinally this can also
-be written <literal>/@example\\.com$/</literal>. If you want to match all
-domains under the <literal>.com</literal> top domain, you could do
-<literal>/@.*\\.com$</literal>. Note that since the matching is done on the
-entire attribute value, you can also use rules like
-<literal>/^[a-k].*@example\\.com$/</literal> to get some of the users in this
-domain to use one server, while other users could be matched by another realm
-block and use another server.
-    </para>
-    </refsect2>
-    <refsect2>
-      <title>Realm block options</title>
-      <para>
-A realm block may contain none, one or multiple <literal>server</literal>
-options. If defined, the values of the <literal>server</literal> options must
-be the names of previously defined server blocks. Normally requests will be
-forwarded to the first server option defined. If there are multiple server
-options, the proxy will do fail-over and use the second server if the first
-is down. If the two first are down, it will try the third etc. If say the
-first server comes back up, it will go back to using that one. Currently
-detection of servers being up or down is based on the use of StatusServer (if
-enabled), and that TCP/TLS/DTLS connections are up.
-      </para>
-      <para>
-A realm block may also contain none, one or multiple
-<literal>accountingServer</literal> options. This is used exactly like the
-<literal>server</literal> option, except that it is used for specifying where
-to send matching accounting requests. The values must be the names of
-previously defined server blocks. When multiple accounting servers are
-defined, there is a failover mechanism similar to the one for the
-<literal>server</literal> option.
-      </para>
-      <para>
-If there is no <literal>server</literal> option, the proxy will if
-<literal>replyMessage</literal> is specified, reply back to the client with
-an Access Reject message. The message contains a replyMessage attribute with
-the value as specified by the <literal>replyMessage</literal> option. Note
-that this is different from having no match since then the request is simply
-ignored. You may wonder why this is useful. One example is if you handle say
-all domains under say <literal>.bv</literal>. Then you may have several realm
-blocks matching the domains that exists, while for other domains under
-<literal>.bv</literal> you want to send a reject. At the same time you might
-want to send all other requests to some default server. After the realms for
-the subdomains, you would then have two realm definitions. One with the name
-<literal>/@.*\\.bv$</literal> with no servers, followed by one with the name
-<literal>*</literal> with the default server defined. This may also be useful
-for blocking particular usernames.
-      </para>
-      <para>
-If there is no <literal>accountingServer</literal> option, the proxy will
-normally do nothing, ignoring accounting requests. There is however an option
-called <literal>accountingResponse</literal>. If this is set to
-<literal>on</literal>, the proxy will log some of the accounting information
-and send an Accounting-Response back. This is useful if you do not care much
-about accounting, but want to stop clients from retransmitting accounting
-requests. By default this option is set to <literal>off</literal>.
-      </para>
-    </refsect2>
-  </refsect1>
-  <refsect1>
-    <title>TLS Block</title>
-    <para>
-The TLS block specifies TLS configuration options and you need at least one
-of these if you have clients or servers using TLS/DTLS. As discussed in the
-client and server block descriptions, a client or server block may reference
-a particular TLS block by name. There are also however the special TLS block
-names <literal>default</literal>, <literal>defaultClient</literal> and
-<literal>defaultServer</literal> which are used as defaults if the client or
-server block does not reference a TLS block. Also note that a TLS block must
-be defined before the client or server block that would use it. If you want
-the same TLS configuration for all TLS/DTLS clients and servers, you need
-just a single tls block named <literal>default</literal>, and the client and
-servers need not refer to it. If you want all TLS/DTLS clients to use one
-config, and all TLS/DTLS servers to use another, then you would be fine only
-defining two TLS blocks named <literal>defaultClient</literal> and
-<literal>defaultServer</literal>. If you want different clients (or different
-servers) to have different TLS parameters, then you may need to create other
-TLS blocks with other names, and reference those from the client or server
-definitions. Note that you could also have say a client block refer to a
-default, even <literal>defaultServer</literal> if you really want to.
-    </para>
-    <para>
-The available TLS block options are <literal>CACertificateFile</literal>,
-<literal>CACertificatePath</literal>, <literal>certificateFile</literal>,
-<literal>certificateKeyFile</literal>,
-<literal>certificateKeyPassword</literal>, <literal>cacheExpiry</literal>,
-<literal>CRLCheck</literal> and <literal>policyOID</literal>.
-When doing RADIUS over TLS/DTLS, both the
-client and the server present certificates, and they are both verified by
-the peer. Hence you must always specify <literal>certificateFile</literal>
-and <literal>certificateKeyFile</literal> options, as well as
-<literal>certificateKeyPassword</literal> if a password is needed to decrypt
-the private key. Note that <literal>CACertificateFile</literal> may be a
-certificate chain. In order to verify certificates, or send a chain of
-certificates to a peer, you also always need to specify
-<literal>CACertificateFile</literal> or <literal>CACertificatePath</literal>.
-Note that you may specify both, in which case the certificates in
-<literal>CACertificateFile</literal> are checked first. By default CRLs are
-not checked. This can be changed by setting <literal>CRLCheck</literal> to
-<literal>on</literal>. One can require peer certificates to adhere to certain
-policies by specifying one or multiple policyOIDs using one or multiple
-<literal>policyOID</literal> options.
-    </para>
-    <para>
-CA certificates and CRLs are normally cached permanently. That is, once a CA
-or CRL has been read, the proxy will never attempt to re-read it. CRLs may
-change relatively often and the proxy should ideally always use the latest
-CRLs. Rather than restarting the proxy, there is an option
-<literal>cacheExpiry</literal> that specifies how many seconds the CA and
-CRL information should be cached. Reasonable values might be say 3600
-(1 hour) or 86400 (24 hours), depending on how frequently CRLs are updated
-and how critical it is to be up to date. This option may be set to zero to
-disable caching.
-    </para>
-  </refsect1>
-  <refsect1>
-    <title>Rewrite Block</title>
-    <para>
-The rewrite block specifies rules that may rewrite RADIUS messages. It can be
-used to add, remove and modify specific attributes from messages received
-from and sent to clients and servers. As discussed in the client and server
-block descriptions, a client or server block may reference a particular
-rewrite block by name. There are however also the special rewrite block names
-<literal>default</literal>, <literal>defaultClient</literal> and
-<literal>defaultServer</literal> which are used as defaults if the client or
-server block does not reference a block. Also note that a rewrite block must
-be defined before the client or server block that would use it. If you want
-the same rewrite rules for input from all clients and servers, you need just
-a single rewrite block named <literal>default</literal>, and the client and
-servers need not refer to it. If you want all clients to use one config, and
-all servers to use another, then you would be fine only defining two rewrite
-blocks named <literal>defaultClient</literal> and
-<literal>defaultServer</literal>. Note that these defaults are only used for
-rewrite on input. No rewriting is done on output unless explicitly specifed
-using the <literal>rewriteOut</literal> option.
-    </para>
-    <para>
-The available rewrite block options
-are <literal>addAttribute</literal>, <literal>addVendorAttribute</literal>,
-<literal>removeAttribute</literal>, <literal>removeVendorAttribute</literal>
-and <literal>modifyAttribute</literal>. They can all be specified none, one
-or multiple times.
-    </para>
-    <para>
-<literal>addAttribute</literal> is used to add attributes to a
-message. The option value must be on the
-form <literal>attribute:value</literal> where attribute is a numerical
-value specifying the attribute.  Simliarly,
-the <literal>addVendorAttribute</literal> is used to specify a vendor
-attribute to be added.  The option value must be on the
-form <literal>vendor:subattribute:value</literal>, where vendor and
-subattribute are numerical values.
-    </para>
-    <para>
-The <literal>removeAttribute</literal> option is used to specify an
-attribute that  should be removed from received messages. The option value
-must be a numerical value specifying which attribute is to be removed.
-Similarly, <literal>removeVendorAttribute</literal> is used to specify a
-vendor attribute that is to be removed. The value can be a numerical value
-for removing all attributes from a given vendor, or on the form
-<literal>vendor:subattribute</literal>, where vendor and subattribute are
-numerical values, for removing a specific subattribute for a specific
-vendor.
-    </para>
-    <para>
-<literal>modifyAttribute</literal> is used to specify modification of
-attributes. The value must be on the form
-<literal>attribute:/regexpmatch/replacement/</literal> where attribute is
-a numerical attribute type, regexpmatch is regexp matching rule and
-replacement specifies how to replace the matching regexp. Example usage:
-      <blockquote>
-        <para>
-modifyAttribute 1:/^(.*)@local$/\1@example.com/

-Mail[1] to the radsecproxy mailing list Wed, 14 Apr 2010 from Stefan
-Winter explaining the radsec-dynsrv.sh and naptr-eduroam.sh scripts.
-
-------------------------------------------------------------
-Hi,
-
-the radsec-dynsrv.sh script right now looks up _radsec._tcp.$REALM. For
-eduroam, the production discovery will rely on S-NAPTRs of "s" type and
-subsequent SRVs.
-
-I have attached a preliminary version of the discovery script which
-takes this logic into account. It could use some public scrutiny (where
-"public" might very well evaluate to Kolbjørn Barmen, who wrote the SRV
-script and knows much more about bash scripting than I do *cough cough*).
-
-As with the other script, you call
-
-naptr-eduroam.sh <realm>
-
-If you need a test case, the DNS domain restena.lu has the NAPTR and the
-SRV record live in place. On my system, you get:
-
-> ./naptr-eduroam.sh restena.lu
-server dynamic_radsec.restena.lu {
-host radius-1.restena.lu:2083
-type TLS
-}
-
-with our live DNS data (radius-1.restena.lu isn't really
-production-ready yet though).
-
-If you're curious, the S-NAPTR for eduroam right now is
-
-x-eduroam:radius.tls
-
-with a possibility of a later IETF allocation of either
-
-aaa:radius.tls (probable)
-eduroam:radius.tls (wishful thinking)
-
-, in which case changing the script to use the new ones is trivial.
-
-Greetings,
-
-Stefan Winter
