Pour lancer la connexion, il suffit de taper ppp-on et ppp-off pour arrêter. Voici le genre de commentaires que vous pouvez voir:

Pour avoir un max d'info, avant de lancer ppp-on, ouvrer un shell en tant que root et taper tail -f /var/log/messages, vous devriez y voir ça:

Cette sortie est un peu différente dans le cas d'une connexion avec identification CHAP (Free).
A noter que le mot de passe de connexion PPP ainsi que le login apparaît en clair dans le fichier de log.
