1. INSTALLATION

  Ignore this file if you have a pre-installed binary package.


2. SIMPLE INSTALLATION

  If you do not need to modify the default configuration, then take
the following steps to build and install the server:


$ ./configure
$ make
$ make install

  The first time after installation, you should run the server as
"root". This will cause the server to create the certificates it
needs for EAP.

$ radiusd -X

  Once that is done, the server can be run from an unpriviledged user
account.


3. UPGRADING

  The installation process will not over-write your existing
configuration files. It will, however, warn you about the files it
did not install.

  For users upgrading from 1.x to 2.0, we STRONGLY recommend that 2.0
be installed in a different location than the existing 1.x
installation. Any local policies can then be migrated gradually to
the new 2.0 configuration. While we have put a lot of time into
ensuring that 2.0 is mostly backwards compatible with 1.x, it is not
COMPLETELY backwards compatible. There are differences that mean it
is simpler and safer to migrate your configurations.

  If you are upgrading an existing installation, please be aware that
at least one default virtual server SHOULD be used. If you don't need
virtual servers, your configuration can remain mostly unchanged.

  If you do need virtual servers, we recommend creating a default one
by editing radiusd.conf, and wrapping all of the authorize,
authenticate, etc. sections in one server block, as follows:

...
  server { # line to add
authorize {
...
}
authenticate {
...
}
accounting {
...
}
...
post-proxy {
...
}
  } # matching line to add
...


4. CUSTOM INSTALLATION

  FreeRADIUS has autoconf support. This means you have to run
./configure, and then run make. To see which configuration options
are supported, run './configure --help', and read it's output. The
following list is a selection from the available flags:

  --enable-shared[=PKGS] build shared libraries [default=yes]
  --enable-static[=PKGS] build static libraries [default=yes]
  --enable-fast-install[=PKGS] optimize for fast installation [default=yes]
  --with-logdir=DIR Directory for logfiles [LOCALSTATEDIR/log]
  --with-radacctdir=PATH Directory for detail files [LOGDIR/radacct]
  --with-raddbdir=DIR Directory for config files [SYSCONFDIR/raddb]
  --with-threads Use threads, if available. (default=yes)
  --with-snmp Compile in SNMP support. (default=yes)
  --disable-ltdl-install Do not install libltdl
  --with-experimental-modules Use experimental and unstable modules. (default=no)
  --enable-developer Turns on super-duper-extra-compile-warnings
                              when using gcc.
  --with-edir Compile with support for Novell eDirectory
                              integration.

  The "make install" stage will install the binaries, the 'man' pages,
and MAY install the configuration files. If you have not installed a
RADIUS server before, then the configuration files for FreeRADIUS will
be installed. If you already have a RADIUS server installed, then

** FreeRADIUS WILL NOT over-write your current configuration. **

  The "make install" process will warn you about the files it could
not install.

  If you DO see a warning message about files that could not be
installed, the it is YOUR RESPONSIBILITY to ensure that the new server
is using the new configuration files, and not the old configuration
files. You may need to manually 'diff' the files. There MAY be
changes in the dictionary files which are REQUIRED for a new version
of the software. These files will NOT be installed over your current
configuration, so you MUST verify and install any problem files by
hand.

  It is EXTREMELY helpful to read the output of both 'configure',
'make', and 'make install'. If a particular module you expected to be
installed was not installed, then the output of the
'configure;make;make install' sequence will tell you why that module
was not installed. Please do NOT post questions to the FreeRADIUS
users list without carefully reading the output of this process.


2. RUNNING THE SERVER

  If the server builds and installs, but doesn't run correctly, then
you may use debugging mode (radiusd -X) to figure out the problem.

  This is your BEST HOPE for understanding the problem. Read ALL of
the messages which are printed to the screen, the answer to your
problem will often be in a warning or error message.

  We really can't emphasize that last sentence enough. Configuring a
RADIUS server for complex local authentication isn't a trivial task.
Your ONLY method for debugging it is to read the debug messages, where
the server will tell you exactly what it's doing, and why. You should
then compare its behaviour to what you intended, and edit the
configuration files as appropriate.

  If you don't use debugging mode, and ask questions on the mailing
list, then the responses will all tell you to use debugging mode. The
server prints out a lot of information in this mode, including
suggestions for fixes to common problems. Look for "WARNING" in the
output, and read the related messages.

   Since the main developers of FreeRADIUS use debugging mode to track
down their configuration problems with the server, it's a good idea
for you to use it, too. If you don't, there is little hope for you to
solve ANY configuration problem related to the server.

  To start the server in debugging mode, do:

$ radiusd -X

  You should see a lot of text printed on the screen as it starts up.
If you don't, or if you see error messages, please read the FAQ:

http://www.freeradius.org/faq/

  If the server says "Ready to process requests.", then it is running
properly. From another shell (or another window), type:

$ radtest test test localhost 0 testing123

  You should see the server print out more messages as it receives the
request, and responds to it. The 'radtest' program should receive the
response within a few seconds. It doesn't matter if the
authentication request is accepted or rejected, what matters is that
the server received the request, and responded to it.

  You can now edit the 'radiusd.conf' file for your local system.
Please read the ENTIRE file carefully, as many configuration options
are only documented in comments in the file.

  Configuring and running the server MAY be complicated. Many modules
have "man" pages. See "man rlm_pap", or "man rlm_*" for information.
Please read the documentation in the doc/ directory. The comments in
the configuration files also contain a lot of documentation.

  If you have any additional issues, the FAQ is also a good place to
check.
