    PPPoE and PPTP VPN Problems

    Hello,
    First please let me apologise for the length of this post.

    The Situation

    I am trying to connect to my university network using Kubuntu 6.06. I can connect using Windows but would like to be able to connect using Linux as I want to start using it as my main OS. I have tried asking the Computer Centre (who run the uni IT) and the Computer Science department (which I belong to) but they don't have anything to suggest.

    The Problem

    In order to connect to the network, you must dial a PPPoE connection and then make a PPTP VPN connection to the server. They have said that "the distribution must support Microsoft CHAPS", which may be one of my stumbling blocks.
    So far, I have tried using pppoeconf to set up the PPPoE connection. I used the default settings when setting up the connection, however the logs show that it does not connect (Please see the output of plog below).
    I have taken a look at KPPP as you can specify to use CHAPS however this only seems to be for analogue modems and the "Connect" button is always greyed out.
    I have also tried editing the "options" file (which I believe/hope contains the pppoeconf settings) and enabled "+chaps" but this had no effect.
    I have checked that I've entered my login details correctly in pppoeconf so I'm not sure why it seems to fail on "Name".

    I'd be incredibly grateful for any help anyone can give with this problem. I'm hoping that when it does get sorted I'll be able to help give the Computer Centre a generic solution to help other users. (I've even posted a message on our "Message of the Day" to see if anyone else is in a similar situation!).

    Going on the following extract from plog, does anyone know how to change from EAP to CHAPS authentication?

      So far I've still had no luck with the PPPoE connection. However, it seems like using pptpconf to set up the VPN connection should work.

      Does anyone have any ideas how I can change the authentication method PPPoE uses so that it uses CHAPS? Setting "+CHAP" in /etc/ppp/options seems to have no effect.

      Many thanks
