Redhat 9.0 PPTPD Problem

Hallo everybody,

I have a problem with PopTop on my Redhat 9.0 machine.

I installed the needed packages
pptpd-1.1.3-3
ppp_mppe-2.4.1-7
kernel-mppe-2.4.20-8.i686.rpm

Than I configured the configuration files
/etc/pptpd.conf
option /etc/ppp/options.pptpd
localip 192.168.34.1 # ip-adress of the linux machine
remoteip 192.168.34.234-238

/etc/ppp/options.pptpd
name sel
lock
auth
proxyarp
-chap
-chapms
+chapms-v2
ipcp-accept-local
ipcp-accept-remote
lcp-echo-failure 3
lcp-echo-interval 5
deflate 0
debug
logfd 2
logfile /var/log/pptp.log
mppe-40
mppe-128
mppe-stateless
mtu 1490
mru 1490
ms-dns 192.168.34.16

/etc/ppp/chap-secrets
# Secrets for authentication using CHAP
# client server secret IP addresses
sel\\test test secret *

than I opened the ports on the iptables firewall:
Port 1723 and the protocol 47.

But I get always the following error when I try to connect me from
my Windows XP machine.

Nov 27 17:01:52 WebCache pptpd[5954]: CTRL: Client 80.180.26.236
control connection started
Nov 27 17:01:52 WebCache pptpd[5954]: CTRL: Starting call (launching
pppd, opening GRE)
Nov 27 17:01:52 WebCache pptpd[5954]: GRE:
read(fd=5,buffer=804d5a0,len=8196) from PTY failed: status = -1 error
= Input/output error
Nov 27 17:01:52 WebCache pptpd[5954]: CTRL: PTY read or GRE write
failed (pty,gre)=(5,6)
Nov 27 17:01:52 WebCache pptpd[5954]: CTRL: Client 80.180.26.236
control connection finished

Please can anyone help me.
I tried several configuration but with no success.

thanx in advance

Hello,

I noticed that the problem occurs when the
auth and the +chapms-v2 in the /etc/option.pptpd
file are set. When I comment this line out,
than I can connect to the server get an IP-Adress
but I am not authenticated in the network.
What could be a possible solution to solve this
problem? Is there a missing package?

thanx

I installed pptpd-1.1.3-4, kernel-mppe-2.4.20-24.9 (had to make the
rpm from the scripts) and then elected to use ppp-2.4.2-0.1b3 (since
ppp >2.4.2 has the mppe stuff built in).

My options.pptpd:
lock
debug
name pptpd
proxyarp
bsdcomp 0
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe
ms-dns 10.1.1.20
---------------------

It does work, at least on one of my test machines. I can vpn in and it
is fine. For me, some machines fail. Go figure.
