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 `' 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. - diff --git a/LICENSE b/LICENSE deleted file mode 100644 index bb754e1..0000000 --- a/LICENSE +++ /dev/null @@ -1,33 +0,0 @@ -The radsecproxy source code is subject to two licenses, you may pick -the one that best suits your needs. - -The radsecproxy source code is subject to the terms of the GNU General -Public License Version 2 or later (GPL). - -Alternatively the radsecproxy source code is subject to the terms of the -below BSD style license. - -* Copyright (c) 2006-2010, UNINETT AS -* All rights reserved. -* -* Redistribution and use in source and binary forms, with or without -* modification, are permitted provided that the following conditions are met: -* * Redistributions of source code must retain the above copyright -* notice, this list of conditions and the following disclaimer. -* * Redistributions in binary form must reproduce the above copyright -* notice, this list of conditions and the following disclaimer in the -* documentation and/or other materials provided with distribution. -* * Neither the name of the UNINETT AS nor the names of its -* contributors may be used to endorse or promote products derived -* from this software without specific prior written permission. -* -* THIS SOFTWARE IS PROVIDED BY UNINETT AS ``AS IS'' AND ANY -* EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED -* WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE -* DISCLAIMED.

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 . diff --git a/THANKS b/THANKS deleted file mode 100644 index 26eef23..0000000 --- a/THANKS +++ /dev/null @@ -1,17 +0,0 @@ -Thanks to Stefan Winter and Andreas Solberg for talking me into doing -this, and the funding from GEANT2.

Overall design - -At startup client and server configurations are read. Two lists -are created, called clconfs and srvconfs.

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.

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.

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.

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 -.sp -\fIDebug level\fR -.sp -This specifies the debug level.

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 -.sp -\fIConfig file path\fR -.sp -This option allows you to specify which config file to use.

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 file URL is the standard one, specifying a local file that -should be used. For syslog, you must use the syntax: -x-syslog:///FACILITY where FACILITY must -be one of LOG_DAEMON, LOG_MAIL, -LOG_USER, LOG_LOCAL0, -LOG_LOCAL1, LOG_LOCAL2, -LOG_LOCAL3, LOG_LOCAL4, -LOG_LOCAL5, LOG_LOCAL6 or -LOG_LOCAL7. 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 - is specified on the command line. - - - - - listenUDP - - -Normally the proxy will listen to the standard RADIUS UDP port -1812 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 *:port where -port is any valid port number. If you also want to specify a specific address -you can do e.g. 192.168.1.1:1812 or -[2001:db8::1]:1812. The port may be omitted if you want the -default one (like in these examples). These examples are equivalent to -192.168.1.1 and 2001:db8::1. Note that -you must use brackets around the IPv6 address. -This option may be specified multiple times to listen to multiple addresses -and/or ports. - - - - - listenTCP - - -This option is similar to the listenUDP option, except -that it is used for receiving connections from TCP clients.

For the full -description, see the configuration syntax section above. - - - - - - - Blocks - -There are five types of blocks, they are client, -server, realm, tls -and rewrite. At least one instance of each of -client and realm is required. This is -necessary for the proxy to do anything useful, and it will exit if not. The -tls block is required if at least one TLS/DTLS client or -server is configured. Note that there can be multiple blocks for each type. -For each type, the block names should be unique. The behaviour with multiple -occurences of the same name for the same block type is undefined. Also note -that some block option values may reference a block by name, in which case -the block name must be previously defined. Hence the order of the blocks may -be significant. - - - - Client Block - -The client block is used to configure a client. That is, tell the proxy about a -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. - - -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. - - -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. - - -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. - - -Alternatively one may use the host option inside a client -block. In that case, the value of the host 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. - - -The allowed options in a client block are host, -type, secret, tls, -certificateNameCheck, -matchCertificateAttribute, -duplicateInterval, addTTL, -rewrite, rewriteIn, -rewriteOut and rewriteAttribute. -We already discussed the -host option. The value of type must be -one of udp, tcp, tls -or dtls. The value of secret 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. - - -For a TLS/DTLS client you may also specify the tls 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 -defaultClient will be used if defined. If not defined, it -will try to use the TLS block named default. 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. - - -For a TLS/DTLS client, the option certificateNameCheck -can be set -to off, to disable the default behaviour of matching CN or -SubjectAltName against the specified hostname or IP address. - - -Additional validation of certificate attributes can be done by use of the -matchCertificateAttribute option. Currently one can only do -some matching of CN and SubjectAltName. For regexp matching on CN, one can use -the value CN:/regexp/. For SubjectAltName one can only do -regexp matching of the URI, this is specified as -SubjectAltName:URI:/regexp/. Note that currently this option -can only be specified once in a client block. - - -The duplicateInterval 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. - - -The addTTL option is similar to the -addTTL option used in the basic config. See that for -details. Any value configured here overrides the basic one when sending -messages to this client. - - -The rewrite option is deprecated. Use -rewriteIn instead. - - -The rewriteIn 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 -tls discussed above, if this option is not used, there is a -fallback to using the rewrite block named -defaultClient if it exists; and if not, a fallback to a -block named default. - - -The rewriteOut option is used in the same way as -rewriteIn, 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. - - -The rewriteAttribute 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: -
- -rewriteAttribute User-Name:/^(.*)@local$/\1@example.com/ - -
- - - - Server Block - -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. - - -Alternatively one may use the host option inside a server -block. In that case, the value of the host 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. - - -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. - - -The allowed options in a server block are host, -port, type, secret, -tls, certificateNameCheck, -matchCertificateAttribute, addTTL, -rewrite, -rewriteIn, rewriteOut, -statusServer, retryCount, -retryInterval, dynamicLookupCommand -and loopPrevention. - - -We already discussed the host option. The -port option allows you to specify which port number the -server uses. The usage of type, secret, -tls, certificateNameCheck, -matchCertificateAttribute, addTTL, -rewrite, -rewriteIn and rewriteOut are just as -specified for the client block above, except that -defaultServer (and not defaultClient) -is the fallback for the tls, rewrite -and rewriteIn options. - - -statusServer can be specified to enable the use of -status-server messages for this server. The value must be either -on or off. The default when not -specified, is off. 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. - - -The options retryCount and -retryInterval 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. - - -The option dynamicLookupCommand 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. - - -Using the loopPrevention option here overrides any -basic setting of this option. See section BASIC -OPTIONS for details on this option. - - - - Realm Block - -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 server -options, and similarly accountingServer options. There are -also replyMessage and accountingResponse -options. We will discuss these later. - - - Realm block names and matching - -In the general case the proxy will look for a @ in the -username attribute, and try to do an exact case insensitive match between what -comes after the @ and the name of the realm block. So if you -get a request with the attribute value anonymous@example.com, -the proxy will go through the realm names in the order they are specified, -looking for a realm block named example.com. - - -There are two exceptions to this, one is the realm name * -which means match everything. Hence if you have a realm block named -*, 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. - - -The other exception is regular expression matching. If the realm name starts -with a /, 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 -/ after the regexp. So as an example, if you want to use -regexp matching the domain example.com you could have a -realm block named /@example\\.com$. Optinally this can also -be written /@example\\.com$/. If you want to match all -domains under the .com top domain, you could do -/@.*\\.com$. Note that since the matching is done on the -entire attribute value, you can also use rules like -/^[a-k].*@example\\.com$/ to get some of the users in this -domain to use one server, while other users could be matched by another realm -block and use another server. - - - - Realm block options - -A realm block may contain none, one or multiple server -options. If defined, the values of the server options must -be the names of previously defined server blocks. Normally requests will be -forwarded to the first server option defined. If there are multiple server -options, the proxy will do fail-over and use the second server if the first -is down. If the two first are down, it will try the third etc. If say the -first server comes back up, it will go back to using that one. Currently -detection of servers being up or down is based on the use of StatusServer (if -enabled), and that TCP/TLS/DTLS connections are up. - - -A realm block may also contain none, one or multiple -accountingServer options. This is used exactly like the -server option, except that it is used for specifying where -to send matching accounting requests. The values must be the names of -previously defined server blocks. When multiple accounting servers are -defined, there is a failover mechanism similar to the one for the -server option. - - -If there is no server option, the proxy will if -replyMessage is specified, reply back to the client with -an Access Reject message. The message contains a replyMessage attribute with -the value as specified by the replyMessage option. Note -that this is different from having no match since then the request is simply -ignored. You may wonder why this is useful. One example is if you handle say -all domains under say .bv. Then you may have several realm -blocks matching the domains that exists, while for other domains under -.bv you want to send a reject. At the same time you might -want to send all other requests to some default server. After the realms for -the subdomains, you would then have two realm definitions. One with the name -/@.*\\.bv$ with no servers, followed by one with the name -* with the default server defined. This may also be useful -for blocking particular usernames. - - -If there is no accountingServer option, the proxy will -normally do nothing, ignoring accounting requests. There is however an option -called accountingResponse. If this is set to -on, 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 off. - - - - - TLS Block - -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 default, defaultClient and -defaultServer 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 default, 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 defaultClient and -defaultServer. 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 defaultServer if you really want to. - - -The available TLS block options are CACertificateFile, -CACertificatePath, certificateFile, -certificateKeyFile, -certificateKeyPassword, cacheExpiry, -CRLCheck and policyOID. -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 certificateFile -and certificateKeyFile options, as well as -certificateKeyPassword if a password is needed to decrypt -the private key. Note that CACertificateFile 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 -CACertificateFile or CACertificatePath. -Note that you may specify both, in which case the certificates in -CACertificateFile are checked first. By default CRLs are -not checked. This can be changed by setting CRLCheck to -on. One can require peer certificates to adhere to certain -policies by specifying one or multiple policyOIDs using one or multiple -policyOID options. - - -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 -cacheExpiry 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. - - - - Rewrite Block - -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 -default, defaultClient and -defaultServer 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 default, 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 defaultClient and -defaultServer. Note that these defaults are only used for -rewrite on input. No rewriting is done on output unless explicitly specifed -using the rewriteOut option. - - -The available rewrite block options -are addAttribute, addVendorAttribute, -removeAttribute, removeVendorAttribute -and modifyAttribute. They can all be specified none, one -or multiple times. - - -addAttribute is used to add attributes to a -message. The option value must be on the -form attribute:value where attribute is a numerical -value specifying the attribute. Simliarly, -the addVendorAttribute is used to specify a vendor -attribute to be added. The option value must be on the -form vendor:subattribute:value, where vendor and -subattribute are numerical values. - - -The removeAttribute 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, removeVendorAttribute 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 -vendor:subattribute, where vendor and subattribute are -numerical values, for removing a specific subattribute for a specific -vendor. - - -modifyAttribute is used to specify modification of -attributes. The value must be on the form -attribute:/regexpmatch/replacement/ where attribute is -a numerical attribute type, regexpmatch is regexp matching rule and -replacement specifies how to replace the matching regexp. Example usage: -
- -modifyAttribute 1:/^(.*)@local$/\1@example.com/ - -
