Title: RE: [speedtouch] Re: Probleme avec pppd

merci � tous ceux qui m'ont aid� � configurer ma connection avec le driver de Benoit. Tout marche parfaitement maintenant. Je voulais juste ajouter ma petite contribution � ce forum en fournissant les scripts qui me permettent de me connecter/deconnecter/reconnecter et incluant des scripts de reconnection automatique et de mise � jour de DNS dynamique (petite compilation de scripts existants) :

Il ne sont surement pas parfait, s'il y a des choses a rajouter ou enlever dit-le moi

Voila j'�sp�re que ces scripts aideront certains � mieux configurer leur connection adsl ;))

# Script to start, restart or stop an ADSL connection with a PPTP client.
# It also launches the checkip script that restarts ADSL if ppp0 is down.
# It also launches the uddns script that updates a DNS adress if the IP has
# changed.

Le fichier ipcheck.py de Kal ([EMAIL PROTECTED]) est trop gros pour le mettre dans ce mail mais vous pouvez le recuperer sur http://support.dyndns.org/dyndns/clients/unix.shtml apr�s avoir cr�� un compte sur dyndns
