OpenVPN le client ne se connecte pas Résolu/Fermé

Question

Bonjour, 

Je viens de remonter un openVPN sur un serveur CentOS 6 64 bits.

J'ai installé l'application, généré mes clés et j'ai un problème.
Le PC client ne se connecte pas.

J'ai refait mon jeu de certificats plusieurs pensant que cela venait de là, mais finalement je ne crois pas.
J'ai plutôt l'impression que ça provient de l'application openvpn, mais je ne vois pas ce qui bloque.

Pour info, je donne l'adresse 200.100.100.50, mais forcément, elle est trop ronde pour être l'adresse réelle du serveur.

Coté serveur l'interface réseau iptunnel se monte correctement :

(extrait du résultat de ifconfig)

Voici ce que j'ai sur le serveur dans /var/log/messages

Je pense que le problème se situe coté serveur, car avec un fichier client openvpn qui fonctionnait avec un ancien serveur, ça ne fonctionne pas mieux. (configuration cliente équivalente, j'ai pris soin de mettre la bonne addresse du serveur avant d'essayer).


Coté client le journal est un peu long, donc avant de le mettre je vais fournir les fichiers :

Dans le journal coté client (Windows), j'ai beaucoup de lignes comme celles-ci :

Mais comme j'ai mis le journal en mode "verbeux" je ne pense pas que ça ait un rapport.

Vers la fin de mon journal coté client (Windows), j'ai ça :

Je pense qu'il y a beaucoup de détails dans ce message, peut-être même un peu trop.
Il y a deux jours que je me bagarre avec cette config et j'ai du mal à m'en sortir.
J'ai déjà regardé sur le site "openvpn.net" et j'ai trouvé des messages décrivant le même problème, mais pas de solutions.

Merci par avance pour votre aide.

bonjour, 
déjà, si tu indiques client-cert-not-required, alors les clés d'authenfication sur le client deviennent inutiles.

lignes à commenter pour le test:  
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
reneg-sec 0
plugin /etc/openvpn/openvpn-auth-pam.so /etc/pam.d/login
client-cert-not-required
username-as-common-name


et donnes l'affichage sur le serveur avant de lancer le client

à la fin, tu dois avoir ça:
   MULTI: TCP INIT maxclients=1024 maxevents=1028   Initialization Sequence Completed

Bonjour,
J'ai modifié un peu la config pour avoir un fichier log distinct au démarrage de l'application.
Et j'ai un fichier qui répertorie les machines connectées.

Le fichier 1194.log (Qui est sensé répertorier les machines connectées) ne voit rien passer.
[root@servername openvpn]# cat 1194.logOpenVPN CLIENT LISTUpdated,Thu Feb 19 19:29:07 2015Common Name,Real Address,Bytes Received,Bytes Sent,Connected SinceROUTING TABLEVirtual Address,Common Name,Real Address,Last RefGLOBAL STATSMax bcast/mcast queue length,0END[root@servername openvpn]#

Le fichier openvpn.log est le même que précédemment, sauf que j'ai réactivé l'authentification par jeu de clés.

Je ne pense pas que le problème provienne des clés, car il apparait même sans ça.
Mais je ne vois pas ou est l'erreur.
Je pense que je vais sauvegarder mon jeu de clés et tenter de réinstaller totalement OpenVPN.

Qu'en penses-tu ?


Ou bien, je peux essayer de l'installer sur une autre machine et m'en servir comme modèle.

Finalement, j'ai repris le fichier sample, puis en même temps, j'ai déplacé les certificats dans le dossier /etc/openvpn.
Et Ca a refonctionné.

Ouf !

Je n'ose pas encore mettre en résolu, on verra demain...
