[Lilux-help] Seeking help with Debian and PPP

Hi List! I'm hoping someone here will be able to help me. I have set up a Debian unstable system for my sister while she was here in Hungary for the summer vacation, now she is back to Luxembourg (Schifflange). She is very happy with her shiny new Gnome 2.6 desktop. The only thing which is not working is the analogue internet connection. We have installed wvdial and gnome-ppp hoping it would work out-of-the-box, but somehow it will not authenticate with neither P&T nor Luxweb. I'm quite certain the username and password etc. are okay, also, the external modem works fine. We tried tweaking /etc/ppp/options, but no luck there. I managed to get my syster to add debug logging and find the relevant info in /var/log/debug, but the only line I'm sure of goes something like "failed to athenticate ourselves with peer". As you can imagine it is nearly impossible for me to solve this problem over the telephone, without having access to the machine. I'm looking for a person in Luxembourg who would be willing to visit my sisters' house and fix the connection, it shouldn't be too difficult for someone who has some experience with ppp links. In return I can offer some programming in PHP, a guided tour in Budapest, or anything else. Thanks for reading this post! Gergo Soros
