Hi,
I'm trying to run pptpd to allow Windows clients to connect via VPN. I have the latest versions of pptpd, ppp (with mppe-mppc patch) and gentoo-sources 2.6.11 (with mppe-mppc patch).
When I try to connect from my windows machine, it fails with error 629. My sytem reports the following:

I've researched as much as possible, and "require-mppe-128" SHOULD work with ppp 2.4.2. I think that's the root of the problem, but I've been unable to figure out how to fix it.
my /etc/ppp/options.pptpd looks like this:
| Code: | name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
lock
nobsdcomp
defaultroute
|
Any help would be appreciated.
Thanks in advance! |

For clarification, I've also tried using "require-mppe" and just plain "mppe". Those are unrecognized as well. |

I played around with it for a bit. It seems to work now:
I upgraded to ppp-2.4.3-r1 (masked) and changed the options file.
/etc/ppp/options.pptp
| Code: | name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
+mppe stateless |
I'm not sure if there's anything else I should have enabled. |
