# Sample Poptop PPP options file /etc/ppp/options.pptpd
# Options used by PPP when a connection arrives from a client.
# This file is pointed to by /etc/pptpd.conf option keyword.
# Changes are effective on the next connection. See "man pppd".
#
# You are expected to change this file to suit your system. As
# packaged, it requires PPP 2.4.2 and the kernel MPPE module.
###############################################################################
# Authentication
# Name of the local system for authentication purposes
# (must match the second field in /etc/ppp/chap-secrets entries)
name pptpd
# Strip the domain prefix from the username before authentication.
# (applies if you use pppd with chapms-strip-domain patch)
#chapms-strip-domain
# Encryption
# (There have been multiple versions of PPP with encryption support,
# choose with of the following sections you will use.)
# BSD licensed ppp-2.4.2 upstream with MPPE only, kernel module ppp_mppe.o
# {{{
refuse-pap
refuse-chap
refuse-mschap
# Require the peer to authenticate itself using MS-CHAPv2 [Microsoft
# Challenge Handshake Authentication Protocol, Version 2] authentication.
require-mschap-v2
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
require-mppe-128
# }}}
# OpenSSL licensed ppp-2.4.1 fork with MPPE only, kernel module mppe.o
# {{{
#-chap
#-chapms
# Require the peer to authenticate itself using MS-CHAPv2 [Microsoft
# Challenge Handshake Authentication Protocol, Version 2] authentication.
#+chapms-v2
# Require MPPE encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
#mppe-40 # enable either 40-bit or 128-bit, not both
#mppe-128
#mppe-stateless
# }}}
# Network and Routing
# If pppd is acting as a server for Microsoft Windows clients, this
# option allows pppd to supply one or two DNS (Domain Name Server)
# addresses to the clients. The first instance of this option
# specifies the primary DNS address; the second instance (if given)
# specifies the secondary DNS address.
#ms-dns 10.0.0.1
#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
10.0.0.3
#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
# system. This will have the effect of making the peer appear to other
# systems to be on the local ethernet.
# (you do not need this if your PPTP server is responsible for routing
# packets to the clients -- James Cameron)
proxyarp
# Logging
# Enable connection debugging facilities.
# (see your syslog configuration for where pppd sends to)
#debug
# Print out all the option values which have been set.
# (often requested by mailing list to verify options)
#dump
# Miscellaneous
# Create a UUCP-style lock file for the pseudo-tty to ensure exclusive
# access.

# Disable BSD-Compress compression

Este é o pedaço de codigo onde o erro é gerado.
if( !(f->callbacks->ackci? (*f->callbacks->ackci)(f, inp, len):
(len == 0)) ){
/* Ack is bad - ignore it */
error("Received bad configure-ack: %P", inp, len);
return;
}
Eu estou com uma grande tendencia a acreditar que nao é bug no codigo. Meus arquivos de configuraçao tambem acredito que nao tenham problemas.
Ele fica recebendo esses "bad configure-ack" desde o pacote #1.
Interessante, nao?
Se alguem tiver alguma ideia sera bem vinda.
