[pptp-server] Cannot dial in

[Orion Poplawski]

Have PPTP 1.1.1 with PPP 2.3.11 installed and configured as follows:

/etc/pptp.conf:
debug
localip 192.168.20.240
remoteip 192.168.20.241-245
listen <server IP>

/etc/ppp/options:
#ms-dns 192.168.20.90
#ms-dns 192.168.20.83
#ms-wins 192.168.20.90
#ms-wins 192.168.20.83
debug
auth
proxyarp
require-chap
#+chapms
#+chapms-v2
#+mppe-40
#+mppe-128
#+mppe-stateless

I've also tried with various permutations of the above.  However is always
get the following error after timing out during "Verifying username and
password.." when trying to connect from my NT4 box:

Disconnected.
Error 629: The data link was terminated by the remote machine.

Looking at the debug log I see:

These last 8 messages repeat a few times , until:

Sep 23 13:09:21 bldigw pppd[24936]: rcvd [LCP ConfReq id=0x0 <magic 0x4891>
<pco

Sep 23 13:09:22 bldigw pptpd[819]: MGR: Reaped child 24935

So it looks like the two machines are commincating fine (no blocked packets)
but they can't agree on the PPP configuration.  Any ideas?
