Bonjour,

Je veux configurer VPN client sous mon serverur debian linux server (linux server 2.6.32-5-amd64) en ligne de commande.
J’ai suivi les étapes dans ce tutorial:

pon $TUNNEL debug dump logfd 2 nodetach

SVP, aideez moi si vous avez des idées.
J’ai bien cherché en net mais je n’arrive pas à résoudre mon problème.

merci d’avance

Salut!
pourquoi compiquer la vie. Installe plutôt openvpn

penvpn fonctionne en mode ligne de commande?
je veux un client vpn et non un server?

merci
