eduroam Africa

Installation and setup for eduroam Africa including eduroam CAT and Switchboard configuration.

If you encounter any issues or need assistance with eduroam setup, email me at ezeasorekene[@]unizik[.]edu[.]ng

Setup eduroam using Freeradius

Install freeradius with mysql (or postgresql) support. Choose any as the case may be

  sudo apt update
  sudo apt install freeradius freeradius-mysql
  sudo apt install freeradius freeradius-postgresql

Create local users in the users file for testing purposes. Open the users file with your preferred editor (vi or nano) and add the text below at the top of the file (preferably replacing the bob line)

sudo nano /etc/freeradius/3.0/users

eduroam    Cleartext-Password := "eduroampass"
       Reply-Message := "Hello, %{User-Name}"

Now restart the freeradius service and test the newly created user. You should get an accept reply.

sudo systemctl restart freeradius.service
radtest eduroam eduroampass localhost 0 testing123

Sometimes, we may want to reject requests immediately instead, then set reject_delay = 0 in radiusd.conf file

sudo nano /etc/freeradius/3.0/radiusd.conf

  reject_delay = 0

Setup eduroam server

Now delete all the files in sites-enabled folder. Create two files called eduroam and eduroam-inner-tunnel and paste the contents below to the corresponding files

sudo rm /etc/freeradius/3.0/sites-enabled/*
sudo touch /etc/freeradius/3.0/sites-enabled/eduroam
sudo nano /etc/freeradius/3.0/sites-enabled/eduroam

Copy the contents of eduroam file in sites-enabled to the new file created

sudo touch /etc/freeradius/3.0/sites-enabled/eduroam-inner-tunnel
sudo nano /etc/freeradius/3.0/sites-enabled/eduroam-inner-tunnel

Copy the contents of eduroam-inner-tunnel file in sites-enabled to the new file created

In some cases, attr_filter.pre-proxy removes by default Operator-Name and Calling-Station-Id, which are two very useful attributes for debugging and analytics. We ensure they don’t get removed by editing pre-proxy file. Open the pre-proxy file and add the following to the end of the file.

sudo nano /etc/freeradius/3.0/mods-config/attr_filter/pre-proxy

Append the contents located here towards the end of the file or make appropriate changes

Configure proxy.conf

Let us now configure our RADIUS server to forward all users it doesn’t recognize to the federation Proxy Server for Nigeria (or any other African country). It will now serve as a Service Provider.

sudo mv /etc/freeradius/3.0/proxy.conf /etc/freeradius/3.0/proxy.conf.original
sudo touch /etc/freeradius/3.0/proxy.conf
sudo nano /etc/freeradius/3.0/proxy.conf

Generate the proxy.conf configuration file from the Switchboard

The contents of proxy.conf generated from the Switchboard typically looks like this file. Some unique values were stripped.

Configure clients

Now let us configure the clients. Again the main contents of the file should be generated and downloaded from the Switchboard. Rename, create and open the clients.conf file and add the generated contents.

sudo mv /etc/freeradius/3.0/clients.conf /etc/freeradius/3.0/clients.conf.original
sudo touch /etc/freeradius/3.0/clients.conf
sudo nano /etc/freeradius/3.0/clients.conf

The contents of proxy.conf generated from the Switchboard typically looks like this file. Some unique values were stripped.

Configure certificate

Let us now make the certificates used by eduroam. Open the ca.cnf file and edit the file to correspond as specified

sudo /etc/freeradius/3.0/certs/ca.cnf

Edit the file as appropriate

default_days            = 3650

[certificate_authority]
countryName             		= NG
stateOrProvinceName     	= Your State
localityName            		= Your City
organizationName        	= Your Institution
emailAddress            		= [email protected]
commonName              	= "Your Institution Certificate Authority"

Now build the ca.pem and ca.der files

cd /etc/freeradius/3.0/certs/
sudo make ca.pem
sudo make ca.der

Edit the server.cnf file to correspond with the values edited in ca.cnf as shown below

sudo nano /etc/freeradius/3.0/certs/server.cnf

default_days            = 3650

[server]
countryName             		= NG
stateOrProvinceName     	= Your State
localityName            		= Your City
organizationName        	= Your Institution
emailAddress            		= [email protected]
commonName              	= "Your Organization eduroam Server Certificate"

Then build the server.pem

cd /etc/freeradius/3.0/certs/
sudo make server.pem

We need to now assign the correct file ownership

sudo chown freerad:freerad ca.*
sudo chown freerad:freerad server.*
sudo chown freerad:freerad index.*

Let us configure the EAP by editing the contents of the eap file to correspond as shown in this file. Here we are telling the eap file where our certificate is located and setting different configuration to use.

sudo rm /etc/freeradius/3.0/mods-enabled/eap
sudo touch /etc/freeradius/3.0/mods-enabled/eap
sudo nano /etc/freeradius/3.0/mods-enabled/eap

Setup testing with rad_eap_test

Let us now setup testing with rad_eap_test

sudo apt install libnl-genl-3-200 libpcsclite1
cd ~/
sudo apt install git
git clone https://github.com/CESNET/rad_eap_test.git
cd rad_eap_test
sudo cp bin/eapol_test /usr/local/bin/

Let us now run any of the following tests using any of the users specified in the users file

./rad_eap_test -H localhost -P 1812 -S testing123 -u eduroam -p eduroampass -m WPA-EAP -e TTLS
./rad_eap_test -H localhost -P 1812 -S testing123 -u eduroam -p eduroampass -m WPA-EAP -e PEAP
./rad_eap_test -H localhost -P 1812 -S testing123 -u eduroam -p eduroampass -m WPA-EAP -e TTLS -2 PAP
./rad_eap_test -H localhost -P 1812 -S testing123 -u eduroam -p eduroampass -m WPA-EAP -e TTLS -2 MSCHAPV2
./rad_eap_test -H localhost -P 1812 -S testing123 -u eduroam -p eduroampass -m WPA-EAP -e PEAP -2 PAP
./rad_eap_test -H localhost -P 1812 -S testing123 -u eduroam -p eduroampass -m WPA-EAP -e PEAP -2 MSCHAPV2
