Je colle ici mes fichier de configuration. J'écrirais la documentation un peu plus tard...Il est déjà  23h40 quand j'écris ce billet et Simba m'attend pour dormir LOL..
FreeRadius: Compilation et installation (mode quick)
J'ai effectué les tests su une Ubutnu 8.04.3 Server Edition fraà ®chement installé sous ma VMWare
apt-get install gcc make libldap2-dev libssl-dev openssl
wget ftp://ftp.freeradius.org/pub/freeradius/freeradius-server-2.1.7.tar.gz -O - | tar xzf -
cd freeradius-server-2.1.7
./configure --prefix=/opt/freeradius && make && make install
Génération des certificats
Une fois freeradius installé, se conformer au fichier
/opt/freeradius/etc/raddb/certs/README que je ne détaillerais pas ici.
A la fin de la génération, ne pas oublier de faire
make random
make dh
Configuration cliente en utilisant wpa_supplicant
Avec la configuration suivante dans le fichier
root@bremko:/var/lib/david/# cat /etc/wpa_supplicant/wifi_belkin54g.conf |grep -v '#'
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="belkin54g"
scan_ssid=1
key_mgmt=WPA-EAP
phase2="auth=PAP"
identity="LOGIN_LDAP"
password="PASSWORD_LDAP"
ca_cert="/etc/wpa_supplicant/certs/ca.pem"
}
Bien sà »r, ici on prendra soin de remplaçer comme il se doit les paramètres
identify et
password. Puisque on utilise ici de l'EAP-TTLS, le certificat n'est pas obligatoire mais bon c'est l'habitude de l'avoir
On aura en lançant la connexion
root@bremko:~# /sbin/wpa_supplicant -P /var/run/wpa_supplicant.ath0.pid -i ath0 -Dwext -c /etc/wpa_supplicant/wifi_belkin54g.conf

C'est avec un certain plaisir que j'ai découvert en pianotant sur le site georezo.net ce soir, cette jeune SSLL (Sociéte de Services en Logiciels Libres).
J'ai procédé à  la mise à  jour de ma documentation pour inclure les recommandations pour Oracle 8.1.7.4.0
