il faut recompiler le pkg en modifiant la version de ppp dans un des header (plugin/patchlevel.h ?) ou alors désactiver le plugin 'logwtmp' dans le fichier de conf

J'ai installé un serveur pptpd sur ma debian, noyau 2.6.18.
j'ai suivi ce tuto:
http://wiki.gadz.org/Linux/TunnelVPNAvecPptp
J'ai testé avec et sans le mppe, mais bon comme j'ai un noyau récent ca devrait etre bon, j'ai bien les modules ip_gre et ppp_mpe.
Je teste dans un réseau local, pas de pare-feu ni routeur.
quand je me connecte depuis un client XP j'ai une erreur 619. et voici le log sur le serveur:
Sep 24 16:04:56 localhost pptpd[1506]: MGR: Manager process started

Qui a une idée ?

# Network and Routing
# If pppd is acting as a server for Microsoft Windows clients, this

#ms-dns 10.0.0.2
# If pppd is acting as a server for Microsoft Windows or "Samba"
# clients, this option allows pppd to supply one or two WINS (Windows
# Internet Name Services) server addresses to the clients. The first
# instance of this option specifies the primary WINS address; the
# second instance (if given) specifies the secondary WINS address.

#ms-wins 10.0.0.4
# Add an entry to this system's ARP [Address Resolution Protocol]
# table with the IP address of the peer and the Ethernet address of this
