[pptp-server] Linux to Linux pptp-connection ?

[christian.jung at professional-solution.com]

Hi,
I Still haven't found a solution to the below problem.  Any advice you can
give would be appreciated.


I am trying to connect to my Linux pptp server from a Linux client
(Suse 6.4 with Kernel 2.2.16, ppp-2.3.11 and pptp 1.0.2)

my options-file on the client looks like this:

  #lock
  debug
  name test
  remotename fdhqw060
  auth
  -pap
  #proxyarp
  +chap
  +chapms
  +chapms-v2
  mppe-40
  mppe-128
  mppe-stateless
  #ms-wins 192.168.1.16
  #ms-dns 192.168.1.3
  require-chap
  netmask 255.255.255.0
  mru 512
  mtu 512
  ktune
  #lcp-echo-failure 10
  #lcp-echo-interval 5
  #deflate 0
  defaultroute
  logfile /var/log/log.options


  And this is the options-file on the server:


  lock
  debug
  name fdhqw060
  auth
  -pap
  #proxyarp
  +chap
  +chapms
  +chapms-v2
  mppe-40
  mppe-128
  mppe-stateless
  ms-wins 192.168.1.16
  ms-dns 192.168.1.3
  require-chap
  netmask 255.255.255.0
  mru 512
  mtu 512
  ktune


If I try to connect to the Server I get the following messages:

(unknown)[20059]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:531]: Client
connection established.
(unknown)[20059]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]: Outgoing call
established.

but I have no working connection and there is no ppp - interface.


The pptp - Server (Suse 6.4 with Kernel 2.2.16 and pptpd 1.0.0) writes the
following lines into the
/var/log/messages - File and repeats the last 6 lines :

This configuration works with a Windows Nt and a Win 98 Client.

Thanks for your help.
