Connection ADSL suite migration de release

Fau-il recréer la connection avec les outils Rh comme adsl-setup
A priori dans /var/log/messages j'ai ceci :
[jb@alpha111 jb]$ pg trace-2.4.21_messages
Aug 6 16:03:29 alpha111 pppd[1849]: Exit.

re-connection.

Manquerai-t-il un ou des argument dans le .config
