[pptp-server] Win98SE2 PPTP connection problem with Encryption

[Jean-Francois Gagnon]

Hi,

I am unable to create a pptp connection with encryption turned on error 691
in the dialup networking.

In /var/log/pptpd.log:
Aug 23 05:43:31 C410745-A pptpd[7179]: CTRL: Client 192.168.1.2 control
connection started
Aug 23 05:43:31 C410745-A pptpd[7179]: CTRL: Starting call (launching pppd,
opening GRE)

char-major-108
Aug 23 05:43:32 C410745-A pptpd[7179]: GRE:
read(fd=5,buffer=804d9c0,len=8196) from PTY failed: status = -1 error =
Input/output error
Aug 23 05:43:32 C410745-A pptpd[7179]: CTRL: PTY read or GRE write failed
(pty,gre)=(5,6)
Aug 23 05:43:32 C410745-A pptpd[7179]: CTRL: Client 192.168.1.2 control
connection finished

My kernel is 2.2.16 and ppp is 2.3.10. I installed the various patches as
indicated in the HOWTO.

Settings in pptpd.options
auth
#require-chap
#require-chapms
#require-chapms-v2
+chap
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless

BTW if I only have +chap turned on and no encryption except for the
password, I can connect with no problem... No problems with my firewall
either.

Thanks for the help
