[pptp-server] CTRL: PTY read or GRE write failed

[Leonardo Rodrigues]

	Hello guys,

	I'm having problems with pptpd. This is my /var/log/messages file:

Feb 13 10:58:25 firewall pptpd[879]: CTRL: Client 200.209.153.40 control 
connection started
Feb 13 10:58:25 firewall pptpd[879]: CTRL: Starting call (launching pppd, 
opening GRE)
Feb 13 10:58:25 firewall kernel: registered device ppp0
Feb 13 10:58:25 firewall pptpd[879]: GRE: 
read(fd=5,buffer=804d8a0,len=8196) from PTY failed: status = -1 error = 
Input/output error
Feb 13 10:58:25 firewall pptpd[879]: CTRL: PTY read or GRE write failed 
(pty,gre)=(5,6)
Feb 13 10:58:25 firewall pptpd[879]: CTRL: Client 200.209.153.40 control 
connection finished

This is /etc/pptpd.conf:

speed 115200
option /etc/ppp/options.pptp
debug
localip 192.168.0.50-100
remoteip 192.168.1.50-100
listen 200.200.88.178
pidfile /var/run/pptpd.pid

this is options.pptp:
lock
debug
auth
+chap

	Finally, pptpd was hand compiled, with:

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var 
--with-pppd-ip-alloc

	I've searched the list archive, and noticed there are some guys with the 
same problem ( GRE 5,6 ) ... but I couldn't find a solution.

	Do anybody knows how to get this working ..... do anybody knows whats the 
REAL cause of this error ???

kernel 2.2.18 and ppp 2.3.11-4

	Hope hearing from you soon,
	Leonardo Rodrigues
