Poptop problems


I'm having problems getting my XP workstation to connect to my new Poptop server.

Here is my configuration:

ppp-2.4.2_cvs_20030610-1
pptpd-1.1.4-b4
kernel-2.4.20-20.7
kernel-mppe-2.4.20-20.7


Here are my config files:

/etc/pptpd.conf:
option /etc/ppp/options.pptpd
debug
localip 192.168.0.2
remoteip 192.168.0.100-200

/etc/ppp/options.pptpd:
lock
debug
noauth
name xxx-pptpd
proxyarp
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe

mtu 1450
mru 1450
ipcp-accept-local
ipcp-accept-remote
lcp-echo-failure 3
lcp-echo-interval 5
nodeflate
ms-wins 192.170.0.1 (bogus, for now)
ms-dns 192.170.0.1 (bogus, for now)

/etc/ppp/chap-secrets:
xxxUser xxx-pptpd *******

I've setup pppd to log activities in /var/log/ppp-log. Here is the part where it bombs out.

May 12 16:35:01 xxxSystems pppd[19116]: sent [CCP ConfReq id=0x1 <mppe +H -M +S +L -D -C>]
May 12 16:35:01xxxSystems pppd[19116]: CHAP peer authentication succeeded for BMHUser

May 12 16:35:01 xxxSystems pppd[19116]: Discarded non-LCP packet when LCP not open
May 12 16:35:01 xxxSystems pptpd[19115]: CTRL: Received PPTP Control Message (type: 15)
May 12 16:35:01 xxxSystems pppd[19116]: rcvd [CCP ConfNak id=0x1 <mppe +H -M +S -L -D -C>]
M

On my Windows XP workstation, I've disabled LCP compression but no success.

Any form of help would be greatly appreciated.

Regards,
Rikk

Rikk,

I am able to connect using my WinXPPro client to my RedHat Linux PPTP (poptop) server.
My server versions are very similar to yours.

I also got the error: MPPE required peer negotiation failed.
Looks like your WinXPPro client does not want to do encryption. The change would be to force it for encryption.

Here's what I did:

In the WinXP-pro VPN client, click Properties, then open the Security Tab.
In the Data encryption box, select the "Require encryption" option.
Then save and retry.

Also, you may want to add "nobsdcomp" to your options.pptpd file.

Hope this works for you.
