This is usually the easiest solution, but at the moment of writing (2016-06) both Ubuntu 16.04 and Ubuntu 14.04.4 contain packages which are EOL and which are not the latest in their own main version. So building from source is recommended as it will contain the latest version, which probably got most of the bugs sorted.

To Install :

Get the latest info about packages from Ubuntu :

Then make sure the system is fully upgraded before installing freeradius :

or

After that has been done we can use apt to install freeradius :

This will install the common,utils, ssl-cert, libdbi-perl, and libfreeradius2 packages. As you probably going to connect to a database or use perl, you should probably also install (some of) the suggested packages. Such as: freeradius-ldap, freeradius-postgresql and freeradius-mysql.

The 'apt install freeradius' command will list all the suggested packages.

If all went well freeradius should now be installed and started. You can start or stop the server with :

or

Suggested is to stop the service and until all is working use freeradius in debug mode.

Right now your config files are in :

Documentation and files for creation of certificates are in :

Installing from source can be daunting for people who never did it but as long as you read the output of the building process, it should tell you what went wrong or what is missing.

First step is to get the source. 2 places that currently offer the material : * freeradius.org : http://freeradius.org/download.html(http://freeradius.org/download.html) * GitHub : https://github.com/FreeRADIUS/freeradius-server(https://github.com/FreeRADIUS/freeradius-server) On GitHub select the branch you wish to install and press clone or download.

Make sure unzip or any other utility that can extract the zip is installed. If not :

Here I download and extract the source to a temporary directory: (I’m using here a directory in my home folder.) Make sure the filename is the same as your downloaded one.

or (depending on type of archive)

Now we need to go into the directory containing the source.

And run the following :

It will probably error out on a clean system. Because the build tools are not installed or because not all dependencies are installed.

Make sure fakeroot and build tools are installed (read the error message!!):

In the file debian/rules we might need to make some changes depending on other packages we might not have installed or support that we do (not) need. In one of my own installs, there was no iodbc database support required as I’m using ldap as a database backend. If I build it will give an error and fail to build because of that. You can modify your install in the following way to prevent the error.

And just before

I create a new line :

You can remove and add any module that you (do not) require this way.

It might also error with more unmet dependencies to be able to build. When you run the command to build the package but it errors out with a dependencies/conflict abortion, install them as well.

In my clean Ubuntu 16.04 install that meant :

After that we try again to build.

If it errors out after it has already started building the deb files, you are sometimes better off starting anew. If that happens :

And unpack the archive again. I.e.

And edit the debian/rules commenting out or adding depending on the error it gave you at the end of the build.

After build has completed without any errors we can finally install.

The install might show errors. Read the error !! Ask questions on freeradius list if you cannot figure it out. v2 will fail install often on open_ssl issues. Quick thing to change to prevent just that error is to edit a config file so freeradius will not complain about ssl that might be vulnerable. ( /etc/freeradius/eap.conf (v2) or /etc/freeradius/modules-enabled/eap )

Building packages should be very simple. First obtain a copy of the source and unpack it. Second, build the packages.

include:Getting-the-Source

Use the following to make sure that all build dependencies are all installed:

Having retrieved whichever version of the source you require and installed dependencies, build the FreeRADIUS packages:

This will build packages in the parent directory, which can be installed with dpkg -i or apt install.

On recent releases you should ensure the source tree is completely clean before running make deb, e.g. do not run ./configure first. (However, on releases before 3.0.16 you must run ./configure first.)

Alternatively, rather than building packages, you can build the source directly. Note that you will need to ensure all required dependencies are installed first (such as libkqueue-dev, libtalloc-dev, and libssl-dev).

Note that version 4 is for developers only. Do not use these versions unless you know what you are doing.

Older versions of Debian and Ubuntu use GCC < 4.8, which lacks support for the C11 features needed to build FreeRADIUS >= v4.0.x.

In order to switch to GCC 4.9

Get the source as described above, then:
