Hi everybody!!!

This is my first post in this mail list.

I have
a problem to connect to my company's vpn. I did some research and
followed several howtos. I have googled for hours:-). My actual
configuration is:
******************************************************************************
Configuration (network manager)

Gateway *******
User: DOMAIN\user
password: blank
Advanced:
PAP and EAP are disabled and MPPE enabled.
******************************************************************************
After clicking on my vpn connection on Network manager and typing my password if I look in /var/log/syslog I see this:

I did some research about this line Aug 20 11:51:08 dell pptp[13401]: nm-pptp-service-13396 warn[decaps_gre:pptp_gre.c:331]: short read (-1): Protocol not available
and I found this http://pptpclient.sourceforge.net/howto ... ead_eproto
*************************************************************************************************************************************************************************************************************************************************************
Protocol not available
Symptom: the following messages appear before the tunnel is established:

log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:580]: Client connection established.
log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:708]: Outgoing call established (call ID 0, peer's call ID 0).
log[decaps_gre:pptp_gre.c:215]: short read (4294967295): Protocol not available
log[callmgr_main:pptp_callmgr.c:245]: Closing connection
log[pptp_conn_close:pptp_ctrl.c:307]: Closing PPTP connection
log[call_callback:pptp_callmgr.c:88]: Closing connection

Diagnosis:
usually caused by the client not binding to the GRE socket early enough
during the connection sequence. The first GRE packet from the server
causes an ICMP protocol unreachable reply. This happens more frequently
on high speed connections.

Workaround: load the ip_gre module. This prevents the ICMP protocol unreachable reply from being generated.

# modprobe ip_gre

Solution:
upgrade to pptp-linux 1.2.0, which binds the GRE socket prior to
calling the server. Loading the ip_gre module should not be needed.

*************************************************************************************************************************************************************************************************************************************************************
My
pptp-linux version is: 1.7.2-1. I have tried this solution an even
including the module ip_gre in /etc/modules and restarting but the
problem persists. The module loads without problem and if I do and
ifconfig -a I can see it. 

I have not firewalls and I'm not
behind a router. I can do a telnet <gateway> 1723 without problems. 

I would appreciate very much if someone could help me
to solve this problem. I don't want to switch back to Windows Xp and I
don't want to hear my boss kidding me saying that Linux is bullshit, 

Regards,
Mr.Ip
