RedHat 9 as VPN server

[nightowl]

I have RedHat 9 (Clarkconnect 2.0) setup as a PPTP VPN server. I am using PoPToP and I can connect to the Linux VPN server but I cannot get MPPE encryption working. I have installed the following RPMs pptpd-1.1.4-1b4.fr.i386.rpm, ppp-2.4.2-0.1b3.i386.rpm, and kernel-mppe-2.4.20-19.9.i686.rpm. When ever I try to enable MPPE I get an error saying that the PPP daemon does not support MPPE. I thought that all I needed to to was patch the kernel to enable MPPE but I guess not. I have also seen some information about a PPP daemon patch for OpenSSL and MPPE. Do I need to install this or something else to get MPPE working?

set the pptpd to use 128 encrytion only here is my /etc/ppp/options file

lock
proxyarp
auth
require-mppe-128
require-mschap-v2
nomppe-40
require-mppe


i was getting the same errors as you unitll i forced chap v2 and mppe 128. may work for you also. i use a full rh9 install but cant see that making too much difference.

Thanks. I'll give that a try but if I remember correctly, whenever I tried to enable MPPE I received an error and I could not complete the VPN process. I could authenticate but I could not register my computer on the network. When I get a chance I will post my pppd options file.

Well, I have changed my ppp options file and still no luck. I get this error message in Windows 2k when trying to connect "Error 734: The PPP control link was terminated". It is still having problems with the MPPE encryption. I am am thinking about trying an older version of the PPP daemon with MPPE support but I am not sure how to remove the current PPP daemon.

EDIT: I found out what my problem was. I installed the wrong kernel patch and it did not take effect. I installed the correct kernel patch and now I have MPPE encryption.
