This is where we can set up our secret key that is used by the clients to connect to the RADIUS server. It should look like this now: # Pluggable Authentication Modules.įinally, the last FreeRADIUS config file that we need to change is the /etc/freeradius/nf. We now need to uncomment the pam line to enable it. Once the file is open, look for the following lines: # Pluggable Authentication Modules. $ sudo vi /etc/freeradius/sites-enabled/default This file tells FreeRADIUS to enable PAM authentication. The second to the last config file on our list to be edited is the /etc/freeradius/sites-enabled/default file. # Instruct FreeRADIUS to use PAM to authenticate usersĭEFAULT Auth-Type := PAM Third config file I found out the hard way when I was troubleshooting an issue with L2TP over IPsec authentication. This will ensure that this line will take precedence. Add the line after all the commented text of the file, just before the DEFAULT Framed Protocol = PPP line. I usually like to add lines at the end of the file. $ sudo vi /etc/freeradius/usersĪdd the lines found below. This file will instruct FreeRADIUS to use PAM libraries to authenticate users as the default. The the next config file that we need to edit is the /etc/freeradius/users file. I will explain more about this once we get to the section where we need to edit the /etc/pam.d/radiusd file. Group = root Option 2 – Use default configurationĪs mentioned, we can just leave the file as default. The default configuration is set to freerad. We’ll now need to find the lines user = and group =. That said, letting FreeRADIUS run as root will have access to the necessary files. My Linux boxes have encrypted home directories so only the owner and root can access these. google_authenticator) in each user’s home directory – I could be totally wrong with this. My observation seems to indicate that FreeRADIUS will also need to access the secret key (. Option 1 – Run as rootĪccording to my limited research, the need to change the user and group to root is because of how both FreeRADIUS and Google Authenticator PAM works. For some people, this is not acceptable so I included instructions below where we’ll leave it as the default configuration. There are two ways in configuring this and it seems that the most popular option is the one with FreeRADIUS running as root. The first config file that we need to edit is the /etc/freeradius/nf file. By no means, one needs to follow the order. There are four config files we need to edit to complete this setup.

$ sudo apt-get install freeradius libpam-google-authenticator -y Configuring FreeRADIUSĪfter the package installation, the next step is to set up FreeRADIUS by editing configuration files. If one went through the Ubuntu installation properly, there might not be a need for this so long as the system is syncing to the time correctly. I added NTP package here since my Google Authenticator configuration is TOTP based.

All we need is to issue one line command. Installing FreeRADIUS and Google Authenticator on Ubuntu 16.04 is very easy. Related: What is multi-factor authentication (MFA)? I have not read it so read through the reviews to see if that will work for your needs. If you want to know more about FreeRADIUS, you might want to check this book out. Since it has PAM library, this is also perfect for integrating it with Google Authenticator PAM.

While there are several RADIUS software out there, FreeRADIUS is one of the most popular RADIUS software of choice in Linux. Update: FreeRADIUS 3.0 with Two-Factor Authentication (2FA) Installing FreeRADIUS and Google Authenticator PAM Update: Migrated FreeRADIUS with Google Authenticator to a Docker container As a result, any hosts that are pointed to my RADIUS server will have the 2FA functionality. In today’s post, I will talk about integrating Google Authenticator PAM to FreeRADIUS. In my previous post, I talked about enabling two-factor authentication (2FA) for my public facing Linux host.
