[pptp-server] New PoPToP - GRE: PTY Read failed.

[Eric H. Raskin]

Hello:

  I've just installed pptpd-1.0.0 and ppp-2.3.10 on my Linux 2.2.14 system.  PPP
seems fine, since I'm up on an ISDN line and all seems OK there.  I've got
masquerading and firewalling configured.  The pertinent lines from my ipchains
listing are:

ACCEPT     tcp  ------  0.0.0.0/0            168.100.187.41        * ->   1723
ACCEPT     47   ------  0.0.0.0/0            168.100.187.41        n/a

This tells me that I'm open for pptp connections.  I'm using the inetd.conf
method to operate, so my inetd.conf contains:

pptpctrl stream tcp     nowait  root    /usr/sbin/tcpd /usr/local/sbin/pptpctrl
1 1 /etc/ppp/options.pptp 1 115200 0 0 0  --buffer--

My /etc/ppp/options.pptp contains:

debug
name gatekeeper
require-chap
+chap
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless

Here's what shows up in my debug log:

Can anyone help me get this working?

TIA
