[pptp-server] encryption not working

[Soren Dayton]

Hi,

I'm running linux 2.2.14-5.0smp (Redhat 6.2)

I got the pptpd 1.0.0-1 rpm.
I got the ppp 2.3.11 mppe compression stuff.

My /etc/ppp/options file looks like

debug
name everest
auth
require-chap
proxyarp
+chap
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless

The client is win2k.

When I don't require encryption, everything works great:

Aug 11 18:09:26 everest pptpd[3548]: GRE: Discarding duplicate packet
Aug 11 18:09:28 everest pptpd[3548]: CTRL: Ignored a SET LINK INFO packet with real ACCMs!

Aug 11 18:09:29 everest pppd[3549]: remote IP address 63.93.29.81


When I do require encryption, It says that encyption is not supported.
This is what happens:

Some stuff is definitely getting used:

# lsmod
Module                  Size  Used by
ppp_deflate            39660   0  (autoclean)
ppp_mppe               13656   0 
ppp                    20268   0  (autoclean) [ppp_deflate ppp_mppe]
slhc                    4336   0  (autoclean) [ppp]



Any ideas?

Thanks,
