Bonsoir à tous, je suis actuellement en résidence étudiante avec une connexion internet (ethernet) derrière un proxy. J'ai donc uniquement le port 80 et 443 (http et https) de disponible. Ayant un serveur chez OVH (kimsufi) je voudrais installer un VPN pour avoir internet sur tous les ports en passant par le 443.
J'ai donc d'abord suivi ce tutoriel: http://doc.ubuntu-fr.org/openvpn
Ceci fait j'ai testé mon VPN en 3G (donc sans proxy pour le moment) et tout fonctionne bien, j'accède à mon VPN sans problème.
Par contre dès que je me remets en ethernet avec le proxy je galère, ça ne marche plus. Voici les logs du client VPN:
Sun Sep 14 01:28:32 2014 TCP connection established with 193.54.225.89:3128
Sun Sep 14 01:28:32 2014 Send to HTTP proxy: 'CONNECT wildcraft.fr:443 HTTP/1.0'
Sun Sep 14 01:28:32 2014 recv_line: TCP port read failed on recv(): Connection reset by peer (errno=54)
Sun Sep 14 01:28:32 2014 TCP/UDP: Closing socket
Sun Sep 14 01:28:32 2014 SIGTERM[soft,init_instance] received, process exiting
Sun Sep 14 01:28:32 2014 MANAGEMENT: >STATE:1410650912,EXITING,init_instance,,
La connexion au serveur proxy a l'air de marcher d'après la première ligne pourtant :/
Voilà ma config du client VPN :
##############################################
# Sample client-side OpenVPN 2.0 config file #
# for connecting to multi-client server. #
# #
# This configuration can be used by multiple #
# clients, however each client should have #
# its own cert and key files. #
# #
# On Windows, you might want to rename this #
# file so it has a .ovpn extension #
##############################################
# Specify that we are a client and that we
# will be pulling certain config file directives

# To use this feature, you will need to generate

De plus, rien ne s'affiche dans la console du côté serveur, comme si je n'arrive pas à y accéder du tout.
